This review summarizes the current understanding of microRNAs in skin biology, highlighting their roles in processes like wound-healing and aging, without presenting any new experimental results.

This study found that cysteine supplementation significantly increases keratin expression in human keratinocytes, and counteracts the negative impact of iron deficiency on keratin production by enhancing iron availability for cellular processes.

This review discusses various biologics for hair aging but reports no agent capable of reversing the natural aging process of hair.

This review examines the diverse roles of SRD5α enzymes across species, focusing on their involvement in steroid synthesis, sexual development, and various physiological processes, but reports no new clinical results.

This study suggests that transfection with modified KGF-mRNA enhances keratinocyte reepithelialization in wound therapy by temporarily increasing growth factor expression without affecting nuclear DNA.

This review discusses how recent advances in live imaging have revealed the dynamic and adaptable nature of stem cells during various biological processes, and reports no clinical results.

This study investigated the identity of Victor Vinnetou as Mbuyisa Makhubu using forensic facial comparison and DNA testing, but the findings were inconclusive, requiring further investigation.

This study found that TPA induces apoptosis in pig renal epithelial cells by affecting cell cycle proteins, and activated ras can prevent this process.

This paper details the early stages of human scar regeneration using topical iodine and examines hair's role in the regeneration process, noting hair's ability to move freely and transport regenerative material.

This research outlines the characteristics and potential applications of a GMP-compliant sodium polyphosphate formulation (Na-polyP-GMP) in cellular energy storage and ATP-dependent processes like skin regeneration and wound healing.

This review highlights that microscopic analysis of human scalp hair remains crucial in forensic science for crime scene investigations, despite limitations such as subjectivity and potential misidentification, and notes that integrating DNA analysis and digital imaging could enhance accuracy.

This biographical abstract highlights George Rogers' pioneering contributions to the understanding of keratin molecular structure and keratinisation biochemistry, including the application of electron microscopy to hair ultrastructure and the discovery of enzymes and gene transcription processes relevant to keratin proteins.

This study found that lateral root formation in plants in response to L. bicolor volatiles involves complex signaling processes, potentially including unknown proteins, CRKs, and ABA pathways.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

This study found that stem cells can temporarily act as non-professional phagocytes during hair cycle regeneration by clearing apoptotic cells through a process requiring local lipids and retinoids for activation, providing insights into their dual role in maintaining tissue integrity.

This review outlines the proposed theories behind the development of alopecia areata, emphasizing the autoimmune process involving lost immune privilege in hair follicles, and stresses the need to pinpoint specific pathogenic mechanisms for potential treatments.
