Summary
The c-Jun N-terminal kinase (JNK) pathway regulates aging by affecting telomerase activity and cellular senescence. Targeting JNK may offer new ways to promote longevity and healthspan.
Area of Science:
- Molecular Biology
- Gerontology
- Cellular Aging
Background:
- Aging is a complex process with poorly understood molecular mechanisms.
- Specific regulatory proteins involved in aging require further investigation.
- The c-Jun N-terminal kinase (JNK) pathway is emerging as a key player in aging.
Purpose of the Study:
- To elucidate the regulatory mechanisms of JNK signaling in aging.
- To provide molecular insights into JNK-mediated aging processes.
- To identify potential therapeutic targets for extending healthspan and longevity.
Main Methods:
- Review of existing literature on JNK signaling and aging.
- Analysis of JNK's role in telomerase activity, senescence, and immune aging.
- Exploration of JNK's interaction with circadian rhythm proteins.
Main Results:
- JNK diminishes telomerase reverse transcriptase activity.
- JNK elevates β-galactosidase activity, a marker of cellular senescence.
- JNK contributes to telomere shortening and immune system aging.
- Circadian rhythm proteins are implicated in JNK-mediated aging.
Conclusions:
- JNK signaling is a critical regulator of aging processes.
- Targeting JNK offers potential therapeutic strategies for age-related decline.
- Interventions focused on JNK may promote longevity and enhance healthspan.

01:07MAPK Signaling Cascades
5.3K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

03:03mTOR Signaling and Cancer Progression
3.8K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

01:20The JAK-STAT Signaling Pathway
8.7K
Several cytokine receptors have tightly bound Janus kinase or JAK proteins attached at their cytosolic tail. Small signaling molecules such as cytokines, growth hormones, or prolactins bind to the cytokine receptors and initiate their dimerization. The dimerization brings the cytosolic JAKs together that trans-phosphorylate and activates each other. The activated JAKs now phosphorylate cytosolic tails of the cytokine receptors, which serve as binding sites for adaptor proteins such as SH2...

01:25cAMP-dependent Protein Kinase Pathways
6.2K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

01:22PI3K/mTOR/AKT Signaling Pathway
3.4K
The mammalian target of rapamycin (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1 (mTORC1) and mTOR complex 2 (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast, mTORC2 consists of a...
