Commonly affected sites include the heart, kidneys, liver, gastrointestinal tract, and nervous system, with cardiac involvement being the primary determinant of prognosis. Due to its nonspecific clinical presentation and multisystem nature, AL amyloidosis is often diagnosed at an advanced stage, ...
Lactylation in gynecological malignancies: a bridge between lactate metabolism and epigenetic therapy
2025-10-30
Lactate, once considered a metabolic waste product, is now recognized as a key regulator of cellular homeostasis and disease progression. In gynecological malignancies—including ovarian, cervical, and endometrial cancers—lactate accumulation drives a novel post-translational modification known as lactylation. This modification serves as a critical bridge between metabolic reprogramming and epigenetic regulation, promoting tumor proliferation, metastasis, and therapy resistance. Emerging therapeutic strategies targeting lactate production, transport, and lactylation itself show significant anticancer potential, particularly when combined with immunotherapy. This ...

Immature brain-supporting cells switch fate to restore blood flow after stroke
2025-10-30
Stroke is a leading cause of death and disability, affecting 1 in 4 people during their lifetime. Stroke happens when blood vessels in the brain get clogged or damaged, impairing blood flow and oxygen supply to the brain, which leads to death of neurons and other brain cells. Although brain damage can be limited by interventions to restore blood flow, most stroke survivors experience some lifelong impairments of e.g. speech, movement, or cognitive function.
Despite the existence of immature stem cells in the brain, their role in repair is uncertain and the brain’s ...
Making more supply to meet the demands of muscle cell therapy
2025-10-30
If cancer is a disease of overabundance, where cells divide without restraint and tumors grow despite the body’s best interests, then degenerative diseases are disorders of deprivation.
When malfunctions occur in the biological machinery our muscles or our brains use for renewal and repairs, these tissues gradually wither. This kind of decline is the hallmark of diseases such as Alzheimer’s disease or Duchenne muscular dystrophy.
Scientists have long sought to develop treatments that enhance the muscle’s self-renewal capabilities ...
