Scientists found a new way aging cells may hide from the immune system — and it could point to future treatments
5+ hour, 19+ min ago (776+ words) Some worn-out cells don't quietly retire. They linger in tissues, release inflammatory signals and may make it harder for neighboring cells to function normally. Scientists call them senescent cells, and their accumulation with age has made them a major target…...
Chemists Craft a One-Handed Molecule That Disarms a Cell-Death Protein
5+ hour, 2+ min ago (661+ words) A single protein called BAX sits at the gateway between life and death for human cells. When tissues are injured, stressed, or deprived of oxygen, BAX springs into action, punching holes in the outer membrane of mitochondria and triggering the…...
ApoA2 Drives Metastasis and Drug Resistance in Liver Cancer Through
5+ hour, 24+ min ago (541+ words) A protein long considered a quiet passenger in the bloodstream has been caught playing a far more sinister role in liver cancer....
OLR1 Emerges as Key Driver of Gastric Cancer Growth and Immune Evasion
6+ hour, 58+ min ago (75+ words) Gastric cancer continues to rank among the most lethal malignancies worldwide, and a new study published in Medical Oncology has identified a molecular culprit that may explain how tumors in the stomach not only grow aggressively but also dismantle the…...
Epigenetic Enzyme Keeps Spinal Disc Cells Metabolically Balanced, Study
7+ hour, 42+ min ago (631+ words) Deep inside the intervertebral disc — the resilient cushion that sits between the vertebrae of the spine — a small population of cells works quietly for decades to keep the tissue functional....
Collagen Switch Turns Fish Fins Into Limb-Like Structures
9+ hour, 18+ min ago (83+ words) When the first fish lineage crawled onto land some 375 million years ago, its fins had to be remodeled into limbs capable of bearing weight. Evolutionary biologists have long focused on the genes that pattern the skeleton—Hox clusters, Sonic hedgehog,…...
One Amino Acid Decides Whether Mitochondria Keep Their Protein Machines
11+ hour, 19+ min ago (75+ words) Mitochondria are the power stations of the cell, but they are also among the most dependent organelles in biology. The vast majority of the roughly one thousand proteins that make up a working mitochondrion are manufactured outside the organelle, in…...
Nanoparticles Emerge as a Powerful New Weapon Against Cellular Aging
11+ hour, 35+ min ago (87+ words) Cellular senescence, one of the most closely studied hallmarks of aging, has long been a paradox in biology. On the one hand, it protects organisms by halting the division of damaged cells that might otherwise become cancerous. On the other,…...
Scientists Discover CD55 Is the Hidden Switch That Powers Natural Killer
11+ hour, 45+ min ago (680+ words) Natural killer cells have long been celebrated as the swift, unsung assassins of the immune system, capable of detecting and destroying tumor cells without the elaborate priming that T cells require....
IMU Biosciences and Eurofins Transplant Genomics Form Strategic Partnership to Advance Transplant-Related Clinical Development Programmes
4+ day, 6+ hour ago (301+ words) Suboptimal immunosuppression remains one of the most persistent challenges in solid organ transplant medicine, contributing to chronic rejection and premature graft loss for hundreds of thousands of recipients worldwide. Despite advances in short-term survival, long-term graft outcomes have stagnated for…...
