The cells lining skin capillaries are constantly sending each other messages—tiny pulses of calcium that help regulate blood ...

Reactive oxygen species (ROS) produced naturally during cellular metabolism often cause oxidative damage to cells. However, these molecules also play an important role in normal cellular signaling.

To function normally, nearly every cell in the human body relies on G-protein coupled receptors (GPCRs) to receive and send ...

We also generated a Hx-induced mouse PH model. CNP ecKO and control Tie2-Cre mice were housed in a Hx chamber (10% O 2) for 4 weeks 19 and then evaluated. RVSP and RV/(LV + IVS) ratios were ...

Xeroderma Pigmentosum C (XPC) is a DNA damage recognition protein central to the global genome nucleotide excision repair (GG-NER) pathway, where it acts as a primary sensor of UV-induced DNA lesions.

Full-body defense does not always look the way textbooks say it should. In planarian flatworms, a newly identified cell type ...

Nerve cells are not just nerve cells. Depending on how finely we distinguish, there are several hundred to several thousand different types of nerve cells in the human brain, according to the latest ...

Senescent "zombie" cells are essential architects required to build and maintain the brain's protective barriers.

Omaveloxolone (approved for Friedreich's ataxia) may help protect cells from stress and correct underlying dysfunction in SMA ...

BPC-157 and TB-500, originating from gastric and thymic sources respectively, both influence angiogenesis, cytoskeletal ...

Before a seedling reaches light, it must grow through darkness with speed and precision. A new tomato study reveals how this ...

Cancer cells are remarkably good at adapting to stress. When treatments damage them, they often find new ways to survive, fueling drug resistance and disease progression.
