TCDD changes skin gene expression and may harm skin health.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

This study examined 16 sporadic trichoblastic tumors and found that although one showed malignant transformation, clinical follow-up revealed no residual or metastatic disease. RNA sequencing indicated a high tumor mutational burden and absence of a UV-related signature, helping to distinguish these tumors from similar growths.

This study found that ritlecitinib, approved for alopecia areata in patients aged 12 and older, has an acceptable safety profile with mild to moderate side effects and no increase in serious adverse events compared to placebo.

This study identifies KLK14 as a significant factor contributing to hair defects and skin inflammation in a mouse model of Netherton syndrome.

This study observed that different alkaline buffers had a significant impact on the volume of liquid consumed by fall armyworm larvae, emphasizing the importance of measuring imbibed volumes to reduce dose errors in bioassays.

This study examined the safety profile of ritlecitinib, a drug for alopecia areata, and found that it does not cause significant QTc prolongation or severe lymphopenia, with no unique safety risks expected in adolescents.

The KDM1 gene helps Venus flytraps close by managing potassium ions.

In these two clinical trials, DS-2325a, a KLK5 inhibitor, was found to be generally safe and well tolerated in healthy volunteers, with mild and non-serious adverse events, suggesting its potential for further development as a treatment for Netherton Syndrome.

In this study, Brca1(S971A/S971A) mice showed a moderately increased risk of spontaneous tumor formation and defects in DNA damage response, suggesting CHK2 phosphorylation of BRCA1 is crucial for tumor suppression.

This study found that serine 44 in the N-terminal head domain of keratin 17 is phosphorylated in response to various stimuli affecting skin keratinocyte growth, linking K17 up-regulation with growth and stress responses in skin epithelium.

This study found that keloid tissues exhibit epithelial-mesenchymal transition-related changes and alterations in gene expression, implicating these processes in the pathogenesis of keloids.

This study found that increased intracellular expression of thymosin β4 is necessary and sufficient to induce PAI-1 gene expression in endothelial cells, potentially mediated through Ku80 as a novel receptor.

This study used cryo-electron microscopy to reveal the structural mechanisms by which TRPV6 and TRPV3 ion channels open, close, and are regulated, providing insights for potential future research.

This study identified a new keratin, K6irs, as a potential histological marker for the inner root sheath of hair follicles in mice and humans, and as a candidate gene for hereditary hair defects.

In this study, researchers identified two types of potassium channels, BK and Kv4.2, in rat Merkel cells and reported that these channels play important roles in repolarizing action potentials and maintaining resting membrane potentials, potentially influencing tactile encoding in these cells.

CTP-543 effectively promotes hair regrowth in adults with moderate to severe alopecia areata.

This review discusses Robertsonian chromosomal translocations and their prevalence in the population, highlighting their association with infertility, and reports no new clinical results.

This review discusses the role of tyrosine kinase signaling pathways in autoimmune and inflammatory skin diseases and reports no new clinical results, highlighting ongoing research into small-molecule tyrosine kinase inhibitors as potential treatments.

This study found that Tsukushi facilitates wound healing in mice by regulating macrophage function and myofibroblast differentiation.

This study suggests that variations in α-keratin proteins influence the structure and characteristics of wool fibers, indicating that keratin genes could serve as useful markers for identifying different wool traits.

This study found that overexpression of PKCepsilon in transgenic mice reduced papilloma development but accelerated carcinoma formation in a skin tumor promotion model.

This study identifies a mechanism where dsRNA activates TLR3 to induce RA production, promoting hair follicle regeneration in mice and suggesting a potential role in human tissue regeneration.

This study identified four immune-related signaling molecules (LGR5, PTN, JAG1, and DKK1) associated with keloid, suggesting their potential role in its pathogenesis and as targets for new treatments.

In this study, researchers found that ex vivo and in vivo administration of the TYK2 inhibitor BMS-986202 prevented immune privilege collapse and promoted hair regrowth in models of alopecia areata, suggesting this approach may offer a new therapeutic avenue deserving of clinical investigation.

This study found that overexpression of PKCɛ in mouse epidermis increased sensitivity to metastatic squamous cell carcinoma, suggesting that a PKCɛ-mediated microenvironment may promote cancer development through specific cytokines like TNFα.

This study found that activating the erbB-2 oncogene in transgenic mice led to severe skin abnormalities and fatal defects, indicating erbB-2's significant role in skin and hair follicle development.

ATR12-351 ointment safely delivers LEKTI protein to the skin, reducing enzyme activity in Netherton syndrome.

This study found that trametinib and vemurafenib increased sebum production and gene expression related to lipid accumulation in hamster sebocytes, which may help explain certain side effects in patients.
