UC San Diego biologists have uncovered a quality control timing mechanism tied to cell division. The “stopwatch” function keeps track of mitosis and acts as a protective measure when the process takes too long, preventing the formation of cancerous cells.

MD Anderson Research Highlights for February 21, 2024
The University of Texas MD Anderson Cancer Center’s Research Highlights showcases the latest breakthroughs in cancer care, research and prevention. These advances are made possible through seamless collaboration between MD Anderson’s world-leading clinicians and scientists, bringing discoveries from the lab to the clinic and back. Recent developments at MD Anderson offer insights into drug-drug interactions for patients with acute myeloid leukemia (AML) and myelodysplastic syndromes; patient-derived xenograft models as a viable translational research tool in early-phase clinical trials; a novel gene expression signature to stratify patients with bladder cancer; a potential therapeutic target to overcome treatment resistance in multiple myeloma; a role for mutant p53 in protecting against ferroptosis in triple-negative breast cancer; and diet modifications to improve treatment outcomes in FLT3-mutated AML.
Protein p53 regulates learning, memory, sociability in mice
Researchers at the Beckman Institute for Advanced Science and Technology have established the protein p53 as critical for regulating sociability, repetitive behavior, and hippocampus-related learning and memory in mice, illuminating the relationship between the protein-coding gene TP53 and neurodevelopmental and psychiatric disorders.
Cancer Prevention and Research Institute of Texas awards $2 Million grant to SMU
The Cancer Prevention and Research Institute of Texas (CPRIT) has awarded $2 million to recruit Annika Wylie to SMU and fund five years of her research, which focuses on the p53 gene, a naturally occurring tumor suppressor.
MD Anderson’s Guillermina Lozano receives AAMC Award for Distinguished Research in the Biomedical Sciences
In recognition of her trailblazing work in uncovering the mechanisms of the p53 tumor suppressor, Guillermina “Gigi” Lozano, Ph.D., chair of Genetics at The University of Texas MD Anderson Cancer Center, has been selected to receive the 2022 Award for Distinguished Research in the Biomedical Sciences by the Association of American Medical Colleges (AAMC).
MD Anderson’s Guillermina Lozano elected to Fellows of the AACR Academy
Guillermina (Gigi) Lozano, Ph.D., chair of Genetics at The University of Texas MD Anderson Cancer Center, has been elected to the 2021 class of Fellows of the American Association for Cancer Research (AACR) Academy in recognition of her pioneering work to describe the p53 tumor suppressor pathway, which is undermined in many cancers.
Mutant Gene-Targeted Immunotherapy Approach Developed
Johns Hopkins Kimmel Cancer Center study co-author Bert Vogelstein, M.D., will present the related talk “Targeting genetic alterations in cancers with immunotherapeutic agents” at 11 a.m., March 1, at the Advances in Genome Biology and Technology (AGBT) conference. More information can be found at: https://www.agbt.org/events/general-meeting/agenda/. NOTE: AGBT provides complimentary press registration to staff and working freelance journalists who wish to cover the meeting. https://www.agbt.org/media/guidelines/
Green Tea Compound Aids p53, “Guardian of the Genome” and Tumor Suppressor
An antioxidant found in green tea may increase levels of p53, a natural anti-cancer protein, known as the “guardian of the genome” for its ability to repair DNA damage or destroy cancerous cells.
Radiation Vulnerability
A new study describes how cellular survival after radiation exposure depends on behavior of the protein p53 over time. In vulnerable tissues, p53 levels go up and remain high, leading to cell death. In tissues that tend to survive radiation damage, p53 levels oscillate up and down.
New drug combination shows promise as powerful treatment for AML
Scientists have identified two drugs that are potent against acute myeloid leukemia (AML) when combined, but only weakly effective when used alone. The researchers were able to significantly enhance cancer cell death by jointly administering the drugs that are only partially effective when used as single-agent therapies.
Cancer-Fighting Gene Restrains ‘Jumping Genes’
DALLAS – Oct. 29, 2020 – About half of all tumors have mutations of the gene p53, normally responsible for warding off cancer. Now, UT Southwestern scientists have discovered a new role for p53 in its fight against tumors: preventing retrotransposons, or “jumping genes,” from hopping around the human genome. In cells with missing or mutated p53, the team found, retrotransposons move and multiply more than usual. The finding could lead to new ways of detecting or treating cancers with p53 mutations.
Moffitt Researchers Discover Specific Molecules that Promote Cancer Progression
In a new article published in the journal Nature Communications, Moffitt Cancer Center researchers describe how the protein TAp63 controls levels of RNA molecules, which subsequently connects the activities of p53 and AKT to promote disease progression.
Rutgers Cancer Institute of New Jersey Research Shows Autophagy Impacts Stress Response Pathways Promoting Survival in Laboratory Models
Research from investigators at Rutgers Cancer Institute of New Jersey shows that a cellular process known as autophagy promotes survival in mouse models by suppressing oxidative stress and a tumor suppressor known as p53.
