Scientists upends scientific understanding of how anticancer drugs kill cancer

BRCA1 and BRCA2 genes play a crucial role in repairing damaged DNA. Mutations in BRCA1 and BRCA2 substantially increase the likelihood of breast and ovarian cancer, respectively. This new research illustrates how small breaks in one strand of DNA can expand into a large single-stranded DNA gap that kills drug-resistant breast BRCA mutant cancer cells. The novel vulnerability in mutant BRCA1 and BRCA2 may be a potential target for new therapeutics.

Future drugs may snap supply chain fueling breast cancer

Cancer cells have an insatiable appetite for energy as they multiply more rapidly than normal cells. Greedy cancer cells hijack various cellular functions to find and exploit energy and other resources, including a group of enzymes that help normal cells maintain a balance of energy. These enzymes, called creatine kinases (CK), allow cells to transport energy produced at the mitochondria to where it is needed throughout the cell. Studies of breast cancer cells have highlighted the importance of a type of CK called ubiquitous mitochondrial creatine kinase (uMtCK).

Study establishes 'ball and chain' mechanism inactivates key mammalian ion channel

A new study has unveiled a precise picture of how an ion channel found in most mammalian cells regulates its own function with a 'ball-and-chain' channel-plugging mechanism. The findings boost the understanding of ion channel biology and could lead to new drugs that target these channels to treat disorders such as epilepsy and hypertension.

Researchers unravel menopause timing, shedding light on ovarian aging and fertility

The research team has developed a theoretical framework that quantitatively predicts menopause timing. By analyzing how ovarian follicles transition through different stages, the researchers' model explains why menopause occurs and sheds light on individual variability and cross-population differences. These insights could improve fertility planning, inform health care decisions related to hormonal therapies and enhance our understanding of age-related health risks associated with ovarian aging.

Data from all 50 states shows early onset breast cancer is on the rise in younger women: Does place of exposure matter?

Breast cancer incidence trends in U.S. women under 40 vary by geography and supports incorporating location information with established risk factors into risk prediction, improving the ability to identify groups of younger women at higher risk for early-onset breast cancer.

Sweet taste receptors in the heart: A new pathway for cardiac regulation

In a surprising discovery, scientists have found that the heart possesses 'sweet taste' receptors, similar to those on our tongues, and that stimulating these receptors with sweet substances can modulate the heartbeat. This research opens new avenues for understanding heart function and potentially for developing novel treatments for heart failure.
