Research identifies, exploits vulnerability in certain high-risk cancers

A recent study published in Cancer Research identified a unique vulnerability in certain high-risk cancers that can be exploited for targeted therapy. Researchers found that cancer cells with alternative lengthening of telomeres (ALT) have a common weakness, leading to resistance to DNA-damaging agents and chemotherapy.

A healthy lifestyle can offset a high genetic risk for stroke, according to new research by UTHealth Houston

A new study published in the Journal of the American Heart Association found that people with high genetic risk for stroke can reduce their risk by 30-45% by adopting a healthy cardiovascular lifestyle. The study followed 11,568 adults over 28 years and showed that modifying lifestyle risk factors can offset genetic risk.

Oncotarget | Role of germline variants in the metastasis of breast carcinomas

Researchers analyzed germline variants in breast cancer patients to identify their role in metastasis development. The study found that host genetic makeup contributes to metastasis through dysregulation of gene expression, promoting the dispersion of metastatic seeds and establishing a conducive environment for their growth.

Moffitt researchers identify tumor-based methylation patterns as cancer biomarkers

The study identified a specific methylation signature, TCF7, which predicts the presence of anti-tumor T cells and patient outcomes. The findings suggest that determining immunoepignomic status through tumor-based expression quantitative trait methylation screening could allow for accurate prediction of patient outcomes.

The protein that keeps the pancreas from digesting itself

Researchers identified estrogen-related receptor gamma (ERR γ) as crucial for preventing pancreatic auto-digestion in mice. In humans, lower levels of ERR γ were found in cells affected by pancreatitis. These findings suggest new therapies regulating ERR γ activity could help prevent or treat these conditions.

Immunotherapy plus chemotherapy before surgery improves outcomes for lung cancer patients

Adding immunotherapy to chemotherapy before surgery reduced the risk of recurrence and death in lung cancer patients by 37%, according to a phase III trial. The treatment also led to a nearly twelvefold increase in pathological complete response, with 24% of patients achieving no active cancer remaining when the tumor was removed.

Accounting for genetic factors that cause normal variations in PSA levels may improve the accuracy of prostate cancer detection

A study suggests that accounting for genetic factors causing normal variations in PSA levels could improve the accuracy of prostate cancer detection. By analyzing data from over 95,000 men, researchers identified a polygenic score that accounted for 7.3-8.7% of variation in baseline PSA levels and was not associated with prostate cancer.

Houston Methodist researchers identify an immunotherapy target to combat glioblastomas

Glioblastomas, the deadliest brain cancer, have evaded immune cells by promoting immunosuppressive myeloid cells. Researchers identified S100A4 as a key molecule that can selectively target these immune suppressive cells. This discovery paves the way for new therapeutic strategies to restore antitumor action in glioblastoma patients.
