This chapter reviews keratins in skin epithelia, including their roles in cellular function and disease, and reports no new experimental results.

This study found that polyamines enhance genome integrity by facilitating homologous recombination-mediated DNA repair, suggesting a novel role for polyamines beyond promoting cell growth and proliferation.

In this study, full-size KRT81 was expressed in both normal breast epithelial and breast cancer cells, and contributed to the migration and invasion abilities of breast cancer cells.

This study found that the XEDAR receptor can activate the non-canonical NF-kB pathway involving p100 processing, which is regulated by interactions with TRAF proteins and specific kinases.

This study found that dutasteride reduced β-amyloid plaque load in a cerebral amyloidosis model, seemingly linked to mitochondrial apoptosis and autophagy processes.

This article reviews the identification and characterization of soluble proteins in horny tissues such as calluses and psoriatic scales, but reports no new clinical results.

This study presents recombinant human hair keratins K31 and K81, observing novel nanostructures from their self-assembly and emphasizing disulfide crosslinking's role in this process.

In this study, topical application of α-methylspermidine during the telogen phase in mice induced hair growth by increasing the polyamine pool and mimicking the anagen phase's characteristics.

A rare benign skin tumor showed unusual features of sebaceous and sweat glands, important for correct diagnosis.

In this study, researchers found that the naked (N) gene in mice indirectly affects the synthesis of structural proteins in mouse hair, resulting in reduced high tyrosine protein content and unusual amino acid compositions.

In this study, oil body-bound oleosin-rhFGF-10 was more efficiently absorbed through the skin and enhanced wound healing and hair growth in mice, compared to prokaryotically-expressed rhFGF-10.

This study found that Gsdma3 mutations in mice led to thicker skin and longer hair infundibula, possibly by negatively regulating β-catenin expression in the epidermis.

This study found that essence containing fermented Opuntia ficus-indica var. sarboten fruits and Lactobacillus rhamnosus promoted more significant hair growth in mice than minoxidil.

In this study, peptide nanofiber gels RG and RJ significantly accelerated the healing of deep second-degree burn wounds in vivo, with greater wound closure rates and enhanced tissue regeneration compared to controls, attributed to increased angiogenesis and reduced systemic inflammation.

This study optimized the extraction process for abomasum protein from Tianshan red deer, identifying two proteins with anti-inflammatory and anti-tumor activities, suggesting they could be beneficial in foods and nutraceuticals.

This study found that elastin-like recombinamer (ELR) wound dressings promote tissue regeneration and stability without rejection in ex vivo and in vivo models, indicating potential for hard-to-heal wound treatment.

In this study, carboxymethylalanyl disulfide keratin was shown to effectively prevent hair damage during repeated bleaching and permanent waving treatments.

This study found that finasteride-loaded microspheres effectively treated androgenic alopecia in a mouse model, showing similar hair growth effects to orally-administered finasteride.

This study found that caffeic acid treatment mitigated the negative effects of acrylamide toxicity in Wistar rats by normalizing tissue and serological indices.

This study found that Tcf3 and Lef1 differently regulate cell differentiation in multipotent skin stem cells, with Tcf3 promoting follicle-like features and Lef1, when modified, promoting sebocyte differentiation.

This review discusses the role of keratins in epithelial cell stress protection and cancer, highlighting their potential as multifunctional regulators and diagnostic markers, without presenting new research findings.

This article highlights the versatility and potential of alginate and its derivatives in tissue engineering applications, discussing their properties, modification techniques, and various uses in enhancing tissue healing, bone regeneration, and cell growth.

This study found that specific human hair keratins are differentially expressed in the hair follicle, suggesting a shared pathway of epithelial differentiation between hair cortex and nail plate cells.

This study found that induced expression of mir-302 can reprogram human hair follicle cells into induced pluripotent stem cells through a novel epigenetic mechanism involving global demethylation.

This study found that autologous platelet-rich plasma increased hair growth potential by enhancing dermal papilla cell proliferation and stimulating key signaling pathways in both cell cultures and mice models.

This study demonstrated that stress-derived neurosteroid THDOC shifts from inhibiting to activating the HPA axis under stress, presenting potential therapeutic targets for stress-related disorders.

This study identified ectodin as a novel BMP inhibitor that modulates BMP signaling in ectodermal development by interacting with SHH and FGF pathways.

This review discusses the role of intrinsic skin signals, rather than serum signals, in regulating melanin synthesis and hair pigmentation, but reports no new experimental data.

PGD2 stops hair growth and is higher in bald men with AGA.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.
