Brain changes linked to obesity result in low sperm count

A UC Riverside-led research team found that obesity causes chronic changes in the brain, leading to reduced connections between neurons and lower testosterone levels. The study suggests that the primary site of obesity's effects on reproductive function is the brain, rather than the testes or pituitary gland.

Drop the stress

Researchers discovered that stress triggers the formation of molecular droplets in the transcription regulator NELF, leading to a rapid downregulation of gene activity. This mechanism is essential for cell survival upon stress, as cells lacking proper NELF condensation experience higher death rates during stress.

Drop the stress

Cells form 'lockdown' strategy by slowing down gene activity when stressed, allowing resources to be diverted for crisis response. NELF protein condensation plays key role in this process.

New molecular mechanism of neuropathic pain in mice

A research group at Hiroshima University found that downregulated spinal astrocyte connexin43 expression leads to sustained neuropathic pain following peripheral nerve injury. Restoring Cx43 function via adenovirus vector may reverse mechanical hypersensitivity and modulate glutamatergic neurotransmission.

CD36 deficiency and age-related macular degeneration

A study published in PLoS Medicine found that CD36 deficiency leads to choroidal involution, a key feature of dry age-related macular degeneration. The research also showed that COX-2 down-regulation plays a crucial role in this process.
