Summary
The protein p62 integrates cellular signals, linking autophagy and mTORC1 activation. This process is crucial for regulating fat cell development (adipogenesis) and energy balance, offering insights into metabolic homeostasis.
Area of Science:
- Metabolic signaling pathways
- Cellular regulation of energy homeostasis
Background:
- Metabolic homeostasis is vital for preventing obesity and diabetes.
- Disruptions in metabolic signaling lead to metabolic diseases.
Purpose of the Study:
- To investigate the molecular mechanisms underlying metabolic homeostasis.
- To explore the role of p62 in integrating cellular signals for metabolic control.
Main Methods:
- In vivo studies were conducted.
- Analysis of molecular pathways involving p62, autophagy, and mTORC1.
Main Results:
- p62 acts as a key linker between autophagy and mTORC1 signaling.
- This linkage regulates adipogenesis and energy balance.
Conclusions:
- p62 plays a critical role in maintaining metabolic homeostasis.
- Targeting the p62-mediated pathway could offer therapeutic strategies for metabolic disorders.

03:03mTOR Signaling and Cancer Progression
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.

01:22PI3K/mTOR/AKT Signaling Pathway
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 rapamycin-insensitive companion...
01:27Autophagy
Autophagy is a self-digesting process by which a cell protects itself from threats both within and outside the cell, ranging from abnormal proteins to invading bacteria. In this process, obsolete components of the cell and invading microbes are degraded by hydrolytic enzymes active in an acidic environment of the lysosomal lumen.
An autophagic pathway consists of a series of signaling events activated in response to diverse stress and physiological conditions such as food deprivation,...

01:18Autophagic Cell Death
Christian de Duve discovered “autophagy,” a process in which cellular components are engulfed by membrane-bound organelles called autophagosomes. The autophagosomes then fuse with lysosomes to digest the enclosed contents. Autophagy is generally activated in cells to prevent cell death. However, cell death is triggered when the damage is beyond repair.

01:19Interactions Between Signaling Pathways
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...
