RNase L suppresses regeneration in mammals.

The researchers found that HOXC13 regulates different keratin proteins in a mixed manner, with certain SNPs impeding this regulation, while also demonstrating negative-feedback by HOXC13 and positive regulation by LEF1 and melatonin on the HOXC13 promoter.

Phospholipase Cδ1 is crucial for normal skin and hair development.

This study found that matriptase, a membrane serine protease, is crucial for maintaining multiple types of epithelial tissues in mice, with its absence leading to severe organ dysfunction and increased permeability.

Researchers created a new mouse model for studying scleroderma.

This study found that BBS7 expression is crucial for maintaining Sonic hedgehog signaling activity and periodontal ligament homeostasis, suggesting its downregulation in occlusal hypofunction affects cell migration and angiogenesis.

Serenoa repens extract may help hair growth in both men and women.

This study found that Punica granatum ethanolic leaf extract may alleviate skin fibrosis in rats by modulating inflammation-related pathways and reducing dermal alterations.

The Celsr1 gene is crucial for normal hair patterning in mice.

In this study, researchers found that syntaxin 9, a novel syntaxin family member, interacts specifically with the epidermal growth factor receptor and may influence its transport and signaling in some epithelial cells.

This article discusses research about Netherton syndrome, highlighting its contributions to understanding epidermal structure, immune responses, and processes like atopic dermatitis, but it reports no new clinical findings.

This study found that Rab5c is crucial for proper HSPC development in zebrafish embryos by regulating Notch and AKT signaling through endocytic trafficking, with both deficiency and overactivation leading to production defects.

The Trichodysplasia spinulosa virus protein can cause abnormal hair growth in mice.

In this study, the deletion of NIPP1 in keratinocytes led to chronic skin inflammation and epidermal changes in mice, with early cell-cycle arrest and premature senescence observed, potentially contributing to reduced mutagen sensitivity.

This study discovered two new species of mites in the hair follicles of squirrel monkeys from South America, potentially causing follicle damage due to secondary infection.

This study found that lncRNA-599554 contributes to the inductive ability of dermal papilla cells in cashmere goats by sponging miR-15a-5p, promoting Wnt3a expression, and potentially influencing hair follicle regeneration.

This study revealed that nestin-expressing progenitor cells capable of becoming ORS keratinocytes are present during both hair follicle development and in adult hair follicles.

This study indicates that the Sp6 gene is crucial for the development of skin, teeth, limbs, and lungs in mice, possibly through regulating apoptosis.

This research investigated the role of EphA1 in embryonic and adult tissues, generating mouse models suggesting potential links to skin and colon cancer, sepsis, and post-traumatic injury.

This study suggests that finasteride might reduce SARS-COV-2 infectivity by inducing epigenetic changes in the TMPRss2 protein, which is crucial for viral activation and multiplication.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study suggests that Sonic hedgehog from hair follicles may support the proliferation of dentate neural stem cells in mice through transport by platelets during the perinatal period.

This study suggests that finasteride may inhibit the enzyme phenylethanolamine N-methyltransferase, which could contribute to its sexual and psychological side effects.

This study proposes that the terminal tuft structure in sensory nerve endings, involving Schwann cell processes and axon fingers, potentially plays a role in mechano-electric transduction in rats.

In this study, a mouse model with a PIK3CA gain-of-function mutation in Schwann cells revealed unique communication with neighboring cells and a glycolytic shift in peripheral nerves, and early alpelisib treatment significantly improved symptoms, though efficacy declined with delayed administration due to limited drug penetration.

This study found that BBS7 is crucial for maintaining Shh signaling and periodontal ligament homeostasis, with occlusal hypofunction leading to its downregulation and impacting cell migration and angiogenesis.

Reduced TRPS1 leads to increased STAT3 and SOX9 in hair follicles, affecting hair growth.

Serenoa repens, a natural compound, can increase hair count and help repair capillaries, making it a promising treatment for hair loss.

This study found that in hidradenitis suppurativa, the proteins SERPINB3/B4 and S100A7/A8/A9 were significantly overexpressed in lesional skin compared to nonlesional skin, suggesting new pathways in the disease's pathogenesis.
