Novel drug may be the answer in battling resistance in aggressive breast cancer

Breast cancer is one of the most frequently diagnosed cancers in women across the globe. It represents one in four of all cancers in women. The survival rates for breast cancer vary across the globe, but when it comes to the metastatic or advanced breast cancer type, it is currently incurable, but there are many treatments available.

Research reveals new mechanism which could lead to premature aging in mother cells

Researchers from the University of Seville and the Andalusian Center of Molecular Biology and Regenerative Medicine, have discovered a new mechanism that makes it possible to understand premature aging in cells with asymmetrical cell division, as is the case with mother cells.

Adding targeted therapy drug to standard treatment benefits aggressive breast cancer patients

A study led by UCLA researchers found that adding ribociclib, a targeted therapy drug, to standard hormone therapy has been shown to significantly improve overall survival in postmenopausal women with advanced hormone-receptor positive/HER2- breast cancer, one of the most common forms of the disease.

Human aging processes may hinder cancer development, study finds

A new study, published in Aging Cell, has found that human aging processes may hinder cancer development.

Cellular aging associated with structural changes in the brain

Telomeres are protective caps at the ends of chromosomes that become shorter with each cell division. If they become so short that the genes they protect could be damaged, the cell stops dividing and renewing.

Study on gene mutations may lead to better diagnosis and treatment for cancer

When a cell divides into two daughter cells, it must replicate its DNA according to a very specific scenario. In the presence of some disruptive elements, however, cancer cells are unable to perform this operation optimally; replication then takes place more slowly and less efficiently.

Study identifies factor essential for tendon growth

Insulin-like growth factor 1 (IGF1) is essential for allowing tendons to adapt to physical activity and grow properly, according to basic science research by investigators at Hospital for Special Surgery.

Biologists observe how microtubules branch in new directions in animal cells

Cell biologist Thomas Maresca and senior research fellow Vikash Verma at the University of Massachusetts Amherst say they have, for the first time, directly observed and recorded in animal cells a pathway called branching microtubule nucleation, a mechanism in cell division that had been imaged in cellular extracts and plant cells but not directly observed in animal cells.

CRISPR may explain why so many experimental cancer drugs fail

Scientists have used CRISPR–Cas9 to investigate how ten cancer drugs interact with their protein target, revealing some intriguing findings.

New gene therapy helps stroke patients develop new neurons

Ischemic stroke is a condition in which parts of the brain lose their blood supply, causing nerve damage. Once brain tissue suffers irreparable harm, the patient will experience irreversible disability or death, depending on the extent of neuronal loss.

Memory-protective drug for Alzheimer’s on the horizon

Scientists have come up with a new drug which could prevent patients with features of Alzheimer’s disease (AD) from suffering memory loss and brain damage.

Small-cell clones in epithelial tissues organize differently than their normal-sized counterparts

Small-cell clones in proliferating epithelia – tissues that line all body surfaces – organize very differently than their normal-sized counterparts, according to a recent study from the Stowers Institute for Medical Research.

Study reshapes the understanding of telomerase's function in normal cells

New research from the University of Maryland and the National Institutes of Health reveals a new role for the enzyme telomerase.

Hyperactive signaling pathway blocks cell division in the aging brain

Scientists from Basel have investigated the activity of stem cells in the brain of mice and discovered a key mechanism that controls cell proliferation.

Head-to-head comparison of three breast cancer drugs reveals important differences

Every year, more than 250,000 women in the U.S. are diagnosed with breast cancer. When detected early, patients with the most common form--which tests positive for hormone receptors (HR+) and negative for the HER2 receptor--usually respond well to treatment.

Study shows synergistic effects of drugs that inhibit cell division in pancreatic cancer

Pancreatic cancer is one of the deadliest cancers, with patients surviving on average less than a year once the disease has spread.

Chemists develop new approach based on graphene nanoflakes for drug delivery

Chemists funded by the SNSF have created a new compound for flexible drug delivery that specifically targets prostate cancer cells. Incorporating four different molecules, the compound prevents tumor cells from multiplying, can be detected by medical imaging and has staying power in the bloodstream.
