Potential relevance to the human ageing process

Main reason for selection
Entry selected based on evidence showing that the gene product to be a target of genes previously linked to ageing
Description

JAK2 is a tyrosine kinase involved in cytokine receptor signalling. Disruption of JAK2 causes embryonic lethality due to the absence of definitive erythropoiesis [1175], however, knockdown or pharmacological inhibition of the JAK-STAT enhances satellite stem cell division potential, resulting in better muscle regeneration [3635].

Administrating JAK1/2 inhibitors to aged mice alleviates adipose and systemic inflammation, reduced frailty, and enhanced physical function. Upon JAK inhibition there was a reduction in inflammatory cytokines and chemokines. In addition, inhibition of the JAK pathway partially restored age-related decline in coordination [4344]. Inhibition of the JAK pathway using RNAi or JAK inhibitors in human cells suppresses the senescence associated secretory phenotype (SASP) [4344]. Its signalling functions and its association with a number of genes previously linked to ageing suggest JAK2 may play some role in ageing, even though a direct association of JAK2 with human ageing has not been established.
