Key Highlights
•
A new study reveals that mitochondrial fission factor (MFF) is a key regulator of appetite-controlling AgRP neurons in the brain, where its deficiency increases calcium uptake and neuronal excitability to enhance food intake. This discovery highlights a specific molecular mechanism in the hypothalamus that could be targeted to better understand and manage metabolic disorders and body weight control.

Researchers identified that the protein Fra-2 controls how pancreatic cancer cells respond to the KRAS inhibitor MRTX-1133, a promising new drug. This finding is significant because KRAS mutations drive most pancreatic cancers, and understanding Fra-2 could help improve the effectiveness of this targeted therapy.

The protective effects of Vitamin E in yak ovarian cells are linked to its ability to block a specific cellular pathway (AMPK/mTOR-mitophagy-ferroptosis axis) that causes cell death under energy stress. This provides a new scientific basis for using Vitamin E to support reproductive health and manage cellular damage in livestock.
