Summary
Retinoic acid receptor responder 2 (RARRES2) is a key factor in keloid (scarring) development. This study shows RARRES2 promotes scarring via the STAT3/HSPG2 pathway, offering a potential therapeutic target.
Area of Science:
- Dermatology
- Molecular Biology
- Genetics
Background:
- Keloid pathogenesis molecular mechanisms remain unclear.
- Identifying novel causal factors is crucial for understanding keloid development.
Purpose of the Study:
- To identify molecular regulators of keloid pathogenesis.
- To investigate the role of retinoic acid receptor responder 2 (RARRES2) in keloid formation.
Main Methods:
- Mendelian randomization analysis
- Multi-omics analyses
- In vitro studies using primary fibroblasts
- In vivo animal models
Main Results:
- Retinoic acid receptor responder 2 (RARRES2) identified as a causal risk factor for keloid.
- RARRES2 is highly expressed in keloid fibroblasts and promotes scarring.
- RARRES2 activates the STAT3/HSPG2 pathway, driving keloid pathogenesis.
Conclusions:
- RARRES2 is a key regulator in keloid pathogenesis via the STAT3-mediated HSPG2 pathway.
- RARRES2 represents a potential molecular target for keloid treatment.

01:20The JAK-STAT Signaling Pathway
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...
01:22PI3K/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...
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.

01:19Interactions 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...

01:12Role Of Notch Signalling In Intestinal Stem Cell Renewal
Notch signaling was first discovered in Drosophila melanogaster, where it is involved in cell lineage differentiation. Notch signaling regulates the maintenance and differentiation of intestinal stem cells or ISCs by controlling the expression of atonal homolog 1 or Atoh1. Atoh1 directs cells to differentiate into secretory cells.
Direct cell-to-cell contact is needed for the activation of Notch signaling. The signal is initiated when a notch ligand binds to a receptor on an adjacent cell, also...

02:23Abnormal Proliferation
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the daughter...
