Viruses attack human cells, and that's usually a bad thing — some Houston researchers have received fresh funding to develop and use the evil powers of viruses for good.

The developing cancer treatment is called oncolytic virotherapy and has risen in popularity among immunotherapy research. The viruses can kill cancer cells while being ineffective to surrounding cells and tissue. Basically, the virus targets the bad guys by "activating an antitumor immune response made of immune cells such as natural killer (NK) cells," according to a news release from the University of Houston.

However exciting this rising OV treatment seems, the early stage development is far from perfect. Shaun Zhang, director of the Center for Nuclear Receptors and Cell Signaling at the University of Houston, is hoping his work will help improve OV treatment and make it more effective.

“We have developed a novel strategy that not only can prevent NK cells from clearing the administered oncolytic virus, but also goes one step further by guiding them to attack tumor cells. We took an entirely different approach to create this oncolytic virotherapy by deleting a region of the gene which has been shown to activate the signaling pathway that enables the virus to replicate in normal cells,” Zhang says in the release.

Zhang, who is also a M.D. Anderson professor in the Department of Biology & Biochemistry, has received a $1.8 million grant from the National Institutes of Health to continue his work.

Zhang and his team are specifically creating a new OV — called FusOn-H2 and based on the Herpes simplex 2 virus.

“Our recent studies showed that arming FusOn-H2 with a chimeric NK engager (C-NK-E) that can engage the infiltrated natural killer cells with tumor cells could significantly enhance the effectiveness of this virotherapy,” he says. “Most importantly, we observed that tumor destruction by the joint effect of the direct oncolysis and the engaged NK cells led to a measurable elicitation of neoantigen-specific antitumor immunity.”

Documentary featuring Houston Nobel Prize winner to air on PBS

to-watch list

Not all heroes wear capes. In fact, our current coronavirus heroes are donning face masks as they save lives. One local health care hero has a different disease as his enemy, and you'll soon be able to stream his story.

Dr. James "Jim" Allison won the 2018 Nobel Prize in Physiology or Medicine for his work in battling cancer by treating the immune system — rather than the tumor. Allison, who is the chair of Immunology and executive director of the Immunotherapy Platform at MD Anderson Cancer Center, has quietly and often, singularly, waged war with cancer utilizing this unique approach.

The soft-spoken trailblazer is the subject of an award-winning documentary, Jim Allison: Breakthrough, which will air on PBS and its streaming channels on Monday, April 27 at 9 pm (check local listings for channel information). Lauded as "the most cheering film of the year" by the Washington Post, the film follows Allison's personal journey to defeat cancer, inspired and driven by the disease killed his mother.

Breakthrough is narrated by Woody Harrelson and features music by Willie Nelson, adding a distinct hint of Texana. (The film was a star at 2019's South by Southwest film festival.) The documentary charts Alice, Texas native as he enrolls at the University of Texas, Austin and ultimately, cultivates an interest in T cells and the immune system — and begins to frequent Austin's legendary music scene. Fascinated by the immune system's power to protect the body from disease, Allison's research soon focuses on how it can be used to treat cancer.

Viewers will find Allison charming, humble, and entertaining: the venerable doctor is also an accomplished blues harmonica player. Director Bill Haney weaves Allison's personal story with the medical case of Sharon Belvin, a patient diagnosed with melanoma in 2004 who soon enrolled in Allison's clinical trials. Belvin has since been entirely cancer-free, according to press materials.

"We are facing a global health challenge that knows no boundaries or race or religion, and we are all relying on gifted and passionate scientists and healthcare workers to contain and ultimately beat this thing," said Haney, in a statement. "Jim Allison and the unrelenting scientists like him are my heroes – and I'll bet they become yours!"

Jim Allison: Breakthrough premieres on Independent Lens at 9 pm Monday, April 27, on PBS, PBS.org, and the PBS Video App.

These 3 medical innovations are ones to watch in Houston

Research roundup

Every day, important research is being completed under the roofs of Houston medical institutions. From immunotherapy to complex studies on how a memory is made, Houston researchers are discovering and analyzing important aspects of the future of medicine.

Here are three research projects currently being conducted around town.

University of Houston's potential solution to sickle cell disease

For the most part, sickle cells have been a mystery to scientists, but one University of Houston professor has recently reported a new finding on how sickle cells are formed — enlightening the medical community with hopes that better understanding the disease may lead to prevention.

Vassiliy Lubchenko, UH associate professor of chemistry, shared his new finding in Nature Communications. He reports that "droplets of liquid, enriched in hemoglobin, form clusters inside some red blood cells when two hemoglobin molecules form a bond — but only briefly, for one thousandth of a second or so," reads a release from UH.

In sickle cell disease, or anemia, red blood cells are crescent shaped and don't flow as easily through narrow blood vessels. The misshapen cells are caused by abnormal hemoglobin molecules that line up into stiff filaments inside red blood cells. Those filaments grow when the protein forms tiny droplets called mesoscopic.

"Though relatively small in number, the mesoscopic clusters pack a punch," says Lubchenko in the release. "They serve as essential nucleation, or growth, centers for things like sickle cell anemia fibers or protein crystals. The sickle cell fibers are the cause of a debilitating and painful disease, while making protein crystals remains to this day the most important tool for structural biologists."

Lubchenko conclusion is that the key to prevent sickle cell disease is to is to stop the formation of the initial clusters so fibers aren't able to grow out of them.

Baylor College of Medicine researchers are leading an initiative to figure out the potential effect of immunotherapy on different types of breast cancers. Their report is featured in Nature Cell Biology.

The scientists zoned in on two types of immune cells — neutrophils and macrophages — and they found frequency differed in a way that indicated potential roles in immunotherapy.

"Focusing on neutrophils and macrophages, we investigated whether different tumors had the same immune cell composition and whether seemingly similar immune components played the same role in tumor growth. Importantly, we wanted to find out whether differences in immune cell composition contributed to the tumors' responses to immunotherapy," says Dr. Xiang 'Shawn' Zhang, professor at the Lester and Sue Smith Breast Center and member of the Dan L Duncan Comprehensive Cancer Center at Baylor College of Medicine, in a news release.

Further exploring the discrepancies between the immune cells and the role they play in tumor growth will help better understand immunotherapy's potential in certain types of breast cancer.

"These findings are just the beginning. They highlight the need to investigate these two cellular types deeper. Under the name 'macrophages' there are many different cellular subtypes and the same stands for neutrophils," Zhang says. "We need to identify at single cell level which subtypes favor and which ones disrupt tumor growth taking also into consideration tumor heterogeneity as both are relevant to therapy."

Rice University, UTHeath, and UH's memory-making study

When you make a memory, your brain cells structurally change. Through a multi-institutional study with researchers from UH, Rice University, and the University of Texas Health Science Center at Houston, we now know more about the way memories are made.

When forming memories, three moving parts work together in the human brain — a binding protein, a structural protein and calcium — to allow for electrical signals to enter neural cells and change the molecular structures in cognition. The scientists compared notes on how on that binding protein works.

The team's study was published in the Proceedings of the National Academy of Sciences. Peter Wolynes, a theoretical physicist at Rice, UH physicist Margaret Cheung, and UTHealth neurobiologist Neal Waxham worked together to understand the complex process memories experience in the process of being made.

"This is one of the most interesting problems in neuroscience: How do short-term chemical changes lead to something long term, like memory?" Waxham says in a release from Rice. "I think one of the most interesting contributions we make is to capture how the system takes changes that happen in milliseconds to seconds and builds something that can outlive the initial signal."

Houston cancer-fighting biotech company introduces its 4th ongoing clinical trial

health report

A Houston-based biotech company has wrapped up enrollment for its most recent clinical trial of its cancer-fighting drug.

Moleculin Biotech Inc. (Nasdaq: MBRX) has launched its fourth ongoing trial — this time focusing on Cutaneous T-Cell Lymphoma, or CTCL, treatment. The company's other three trials include treatment for glioblastoma, an aggressive brain cancer, pancreatic cancer, one of the most virulent killers in oncology, and acute myeloid leukemia, or AML.

To treat these various types of cancers, Moleculin has a several drugs it's in preclinical or clinical trials testing — most biotech companies have only one they focus on. WP1220 is the drug that will be used in this trial for topical CTCL treatment of the cancer's resulting skin lesions.

"We believe there continues to be an unmet need for an improved topical therapy for Stage I-III CTCL skin lesions," says Walter Klemp, Moleculin's chairman and CEO, in a news release, "especially one that may avoid significant unwanted side effects."

WP1220 is what's known as a p-STAT3 inhibitor. STAT3 is a transcription factor that encourages tumor development. Moleculin's technology directly attacks the tumor, but also quiets T Cells, which allows the body's own immune system to fight the cancer itself. Essentially, it works both as chemotherapy and immunotherapy.

"This proof of concept, if successful, could be an important first demonstration of a therapeutic effect in humans from such a p-STAT3 inhibitor," Klemp continues. "We are pleased with how quickly this trial reached full recruitment and we are hopeful to be able to announce results from this trial yet this year."

Klemp founded the company in 2007, and Moleculin went public in 2016. Now, with the company's four clinical trials, Moleculin is even closer to saving lives with its products.

"Notwithstanding the relatively rare nature of CTCL, we believe showing activity with one of our STAT3 inhibitors, within our WP1066 family of molecules, could be an indicator of both the value of p-STAT3 as a target and the potential for our drugs in other cancers where STAT3 is highly activated," Klemp says in the release.

Houston-based veterinary biotech startup modernizes cancer treatments for dogs

Paw-dern medicine

More than three years after its founding, Houston-based veterinary biotech company CAVU Biotherapies recently accomplished a significant milestone. In October, CAVU's specialized immunotherapy was administered to its first cancer patient: a black Labrador in Pennsylvania diagnosed with B-cell lymphoma.

Dr. Colleen O'Connor, CEO and founder of CAVU Biotherapies, established the company in July 2015 with a goal to help pets live longer post-cancer diagnoses. O'Connor, who earned a PhD in toxicology with a specialty in immunology, has more than a decade of hands-on experience researching cancer treatments.

"Our goal is to scale up and be able to increase our dogs' qualities of life with us," O'Connor said. "We want to keep families intact longer and we want to be able to modernize cancer care for our animals."

At CAVU, O'Connor dedicates her time to modernizing cancer care for dogs by developing an Autologous Prescription Product, otherwise known as adoptive T-cell therapy for dogs. The T-cell therapy is currently offered as a companion treatment to other canine cancer treatments, such as chemotherapy, radiation or surgery, O'Connor said.

Historically, cancer research for animals has lagged behind that of humans, and cancer diagnoses have come late due to the language barrier, O'Connor said. Of the dogs who enter remission, a majority of them relapse within 10 months to one year, she said.

"A majority [of dogs] are diagnosed at stage four, and you have to become very aggressive," O'Connor said. "For B-cell lymphoma, with the current treatments right now and the current standard of [therapies], less than 20 percent make it to two years post-diagnosis."

Launching CAVU
O'Connor first began studying T-cell therapy for humans with cancer during her post-doctoral fellowship at M.D. Anderson Cancer Center. Her fellowship also partnered with Texas A&M University's Small Animal Hospital to develop a clinical trial studying the effects of adoptive T-cell therapies on dogs with B-cell lymphoma.

T-cell therapy is a cellular-based treatment in which a type of white blood cells — or the cells that fight off tumors and infections — are harvested from blood samples drawn from patients. The cells are then injected back into the patient through an IV to fight the cancerous cells, O'Connor said.

Unexpectedly, O'Connor's 19-year-old dog, Bubbles, was diagnosed with transitional cell carcinoma in 2008 and later dying from it in December 2009. Five years later, O'Connor's sister's 6-year-old dog, Daisy, also died from transitional cell carcinoma. O'Connor said she remembers feeling helpless as she watched the dogs succumb to the disease.

"I was giving them drugs and protocols that were from 1980 … and I was really upset that there wasn't much more we could do for our dogs — especially because I treat my dogs like family," O'Connor said.

That was when O'Connor realized she wanted to help prevent other people from feeling the pain of losing their furry family members. While T-cell therapy is not a new method of treating cancer in humans, O'Connor focused on modifying the serum to create a treatment plan appropriate for dogs.

However, launching a company focusing specifically on treating cancer in animals was not without its challenges; O'Connor said she had to learn how to start a business, make industry connections, and adopt an entrepreneurial mindset.

To help with this, CAVU also connected with various entrepreneurial accelerators, such as Houston Technology Center and Station Houston, which are associations that help place young businesses in front of investors.

CAVU later became a member of the Houston Angel Network — a group of private investors of high net worth individuals that as a group invest in startups. By presenting her business to HAN and its investors, CAVU was able to gain financial backing.

CAVU also recently joined the Capital Factory in early 2018, an Austin-based accelerator program for entrepreneurs in Texas. O'Connor said the program has helped her meet investors, mentors and other startups.

"The way I overcame a lot of this [the early challenges] is by education, listening and trying to navigate and talk with as many of the right people as I could that had experience," she said.

The future of CAVU
Since CAVU treated its first patient in October, CAVU's adoptive T-cell therapy treatment has been administered to six dogs, O'Connor said. CAVU's T-cell therapy is currently available at more than 12 veterinary clinics across the country, including clinics in Texas, Florida, Pennsylvania, New York, North Carolina, and Missouri.

Additionally, four Houston-area clinics currently offer the T-cell therapy treatment: Garden Oaks Veterinary Clinic, Bayou City Veterinary Hospital, Memorial-610 Hospital for Animals, and Sugar Land Veterinary Specialists.

In order for a dog to be considered as a candidate — though it is ultimately up to the veterinarian on whether the T-cell therapy is right for specific dogs — the dogs must weigh more than 8 pounds, not be allergic to mouse or cow products and have no active autoimmune diseases.

The company also launched a new clinical trial with A&M University in October, looking at the effects of CAVU's T-cell therapy coupled with reduced chemotherapy periods for dogs, from roughly 19 to 26 weeks of chemotherapy to 6 to 8 weeks.

While CAVU's therapy is currently only available for dogs, O'Connor said her team plans to modify the T-cell therapy to be administered in other animals.

"We have a lot of cat owners ask us [about treatment] and we are going to do that for the next round in funding," she said. "We're going to look at how to translate this for cats and eventually horses."

O'Connor said that CAVU will launch more clinical trials with A&M University's Small Animal Hospital in the future, with CAVU aiming to make T-cell therapy treatments for cats and horses available in 2020.

Looking back, O'Connor said she has come a long way in her career path: from working with sea animals at the Newport Aquarium in Kentucky to studying human immunology and toxicology, but she's returned to studying animals.

"It's amazing how I pivoted, but at the end of the day I kind of came back to animals … and I came back full circle in a way I could have never expected," she said.

2 Houston suburbs roll onto top-15 spots on U-Haul’s list of growing cities

on the move

More movers hauled their belongings to Texas than any other state last year. And those headed to the Greater Houston area were mostly pointed toward Missouri City and Conroe, according to a new study.

In its recently released annual growth report, U-Haul ranks Missouri City and Conroe at No. 13 and No. 19, respectively among U.S. cities with the most inbound moves via U-Haul trucks in 2022. Richardson was the only other Texas cities to make the list coming in at No. 15.

Texas ranks No. 1 overall as the state with the most in-bound moves using U-Haul trucks. This is the second year in a row and the fifth year since 2016 that Texas has earned the distinction.

“The 2022 trends in migration followed very similar patterns to 2021 with Texas, Florida, the Carolinas and the Southwest continuing to see solid growth,” U-Haul international president John Taylor says in a news release. “We still have areas with strong demand for one-way rentals. While overall migration in 2021 was record-breaking, we continue to experience significant customer demand to move out of some geographic areas to destinations at the top of our growth list.”

U-Haul determines the top 25 cities by analyzing more than 2 million one-way U-Haul transactions over the calendar year. Then the company calculated the net gain of one-way U-Haul trucks entering a specific area versus departing from that area. The top U-Haul growth states are determined the same way.

The studies note that U-Haul migration trends do not directly correlate to population or economic growth — but they are an “effective gauge” of how well cities and states are attracting and maintaining residents.

Missouri City is known for its convenient location only minutes from downtown Houston. The city’s proximity to major freeways, rail lines, the Port of Houston, and Bush and Hobby Airports links its businesses with customers “around the nation and the world,” per its website.

The No. 19-ranked city of Conroe is “the perfect blend of starry nights and city lights,” according to the Visit Conroe website. Conroe offers plenty of outdoor activities, as it is bordered by Lake Conroe, Sam Houston National Forest and W. Goodrich Jones State Forest. But it also has a busy downtown area with breweries, theaters, shopping and live music.

Houston expert: Space tourism is the future — do we have the workforce to run it?

guest column

Throughout history, humans have always been fascinated in exploring and traveling around the world, taking them to many exotic places far and away. On the same token, ever since the dimension of space travel has been inaugurated with multiple private companies launching rockets into space, it has become an agenda to make space travel public and accessible to all. We believe that space travel is the next frontier for tourism just like for our forefathers world travel to faraway places was the next frontier, for recreational and adventure purposes.

In a world racing on technology, we can picture flying cars, invisible doors, and international cuisine in space. With this rapid expansion of the land, the idea of space tourism has stirred the space industry to think about running businesses, start trade, and set up universalization beyond the ring of the earth. It is no longer science fiction but our immediate future. However, the true question remains. Who will be responsible for all of it? Are we training the right workforce that is needed to build and run all of this?

Space tourism is an exciting idea in theory, traveling to extra-terrestrial destinations, exploring new planets, all by being in an anti-gravitational environment. Through these diminishing borders and rapid advancements soon we'll be living the space life, all the virtual, metaverse gigs coming to reality. But before that let's explore space tourism and how the solar system will welcome humans.

What is Space tourism?

Ever since 1967, Apollo opened the getaway of space travel and the technological intervention spun to rise. Just like nomad tourism, space tourism is human space travel for commercializing interstellar for leisure or pleasurable adventures of the unknown. Space has different levels of horizons, according to research, orbital space has high speeds of 17,400 mph to allow the rocket to orbit around the Earth without falling onto the land. While lunar space tourism goes into subcortical flights and brings people back at a slower speed.

Studies have shown that in the upcoming years, commercial space exploration will hike up the economical database, by generating more than expected revenue. On these grounds, space tourism won't be limited to suborbital flights but rather take onto orbital flights, this revolutionary expenditure will change the future.

Everything aligns when the right team works together endlessly to reach the stars. The space exploration will only take place with enthusiastic and empowered individuals catering towards their roles.

Astronomers, space scientists, meteorologists, plasma physicists, aerospace engineers, avionics technicians, technical writers, space producers, and more will work in the field to make this space dream come true.

The attraction of Space exploration

Curiosity is the gateway to the seven wonders of the world. Humans are born with novelty-seeking, the drive to explore the unknown and push boundaries. This exploration has benefited society in a million ways, from making bulbs to jets.

The attraction towards exploring the space stems from the same desire for novelty seeking. We want to answer the most difficult questions about the universe, is there only darkness beyond that sky? Can we live on another planet if ours die? To address the challenges of space and the world, we have created new technologies, industries, and a union worldwide. This shows how vital space exploration is to humans. Many astronauts dwell on the idea of seeing the iconic thin blue outline of our planet, the quintessential experience makes the astronaut go back and back. However, are we entering this dimension with the right skills? Is our future workforce ready to take need the best

Who will lead the path?

The main question that still goes unanswered is who will run space tourism. When it comes to the future, there are infinite options. One decision and you will fly into an endless sky.

This expenditure has opened multiple career opportunities for the future workforce to take on for diversification and exploration of space. Currently, we cannot predict how people will find meaning and improve their lives through space tourism, but it will be a soul-awakening experience. According to experts, travelers would prefer a livelihood in space for which companies are working day and night to figure out accommodation and properties. The ideas include having space hotels, offices, research labs, and tents for operations.

Lastly, space tourism is just a start, we are moving into a dimensional field of physics and astronomy to create new opportunities and ground-breaking inventions to explore the untouchable. The new era of more refined and thoroughly accessed careers are on the rise, let's see how the world evolves in the next 10 years.
