T cell activation—the process by which these key immune defenders recognize threats and mobilize against them—depends on exquisitely timed molecular signals. Now researchers have captured one of the ...

(MEMPHIS, Tenn. – November 6, 2025) The enzyme RNA polymerase II transcribes genes into messenger RNA. This process is guided by modifications to the enzyme’s “tail” called phosphorylation patterns.

Clinically available KRAS inhibitors mainly target G12C, which is rare in PDAC and often acquires resistance. Oncogenic KRAS inactivates RB1 via CDK4/6, while RB1 mutation is rare. Thus, CDK4/6 ...
