In this study, researchers found that impaired cholesterol biosynthesis in hair follicles may trigger an inflammatory immune response linked to primary cicatricial alopecia, providing new insights into the disorder's pathogenesis.

This study found that disrupted cholesterol homeostasis in scalp samples from cicatricial alopecia patients hinders hair regrowth by affecting hair follicle stem cell markers, with resulting effects confirmed in vitro and in animal models.

In this mouse study, hair growth defects associated with the Gk5 null allele were partially alleviated by simvastatin treatment, suggesting GK5 plays a key role in skin-specific cholesterol regulation.

This study found that in primary cicatricial alopecia, reducing cholesterol production and targeting EMT modulators like PPARγ, AhR, AGTR, and TGFβ with siRNA may help mitigate hair follicle damage by modulating epithelial-mesenchymal transition, suggesting potential therapeutic strategies for slowing PCA progression.

This study found that impairments in cholesterol biosynthesis in hair follicles of primary cicatricial alopecia patients trigger an inflammatory immune response, potentially linking sterols to inflammation in the disease's pathogenesis.

This study found that disrupted cholesterol homeostasis impairs hair regrowth in individuals with primary cicatricial alopecia by damaging hair follicle stem cells, highlighting the importance of cholesterol in maintaining stem cell function and hair follicle integrity.

This commentary reviews potential dietary and mineral influences on androgenetic alopecia and suggests considering a diet low in cholesterol and glycaemic index with improved glucose control and magnesium fortification, without new clinical results.

In this study, researchers found that finasteride inhibits progesterone synthesis by blocking cholesterol side-chain cleavage in mouse-derived MA-10 Leydig cells, but this effect may not be evident in human or rat cells.

This review discusses the roles of interferon-γ and PPAR-γ-mediated signalling in scarring alopecia, suggesting these pathways as potential therapeutic targets, but it reports no new empirical results.

This study identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

This review discusses 46,XY disorders of sex development caused by defects in androgen production and highlights the need for long-term care from experienced multidisciplinary teams, but it reports no new clinical findings.

In this study, higher expression levels of aromatase and steroidogenic acute regulatory protein were correlated with increased estrogen synthesis and fewer hair follicles in human skin, suggesting a link to elastic fiber formation and hair growth.

This review discusses potential treatments for androgen excess in polycystic ovary syndrome and reports no new findings, emphasizing the importance of individualized antiandrogenic management to minimize side effects.

This review highlights that while dexamethasone may reduce mortality in severe COVID-19, no other drugs have proven effectiveness for treatment, emphasizing the need for clinical trials of existing medications.

This study suggests that using cholesterol-free liposomes, specifically PPD-Lip, as a delivery system with dutasteride may enhance the treatment of androgenetic alopecia by promoting hair regrowth in mice models.

This study identified mutations in the SREBF1 gene that impair SREBP1 function, potentially contributing to IFAP syndrome by affecting skin, hair, and eye development.

This study identified biallelic variants in the LSS gene as a possible genetic cause of palmoplantar keratoderma-congenital alopecia syndrome type 2, highlighting the role of cholesterol synthesis in skin cornification.

This study found that Insig deficiency in the skin of mice causes cholesterol precursors to accumulate, leading to defective hair development and skin abnormalities, which were alleviated by simvastatin treatment.

In this review and meta-analysis, the authors concluded that 5α-reductase inhibitor therapy is not consistently associated with significant increases in serum testosterone levels in men.

This study demonstrated that benzothiazepines, such as diltiazem and JTV-519, exert anxiolytic-like effects through allopregnanolone biosynthesis in mice, similar to carbamazepine.

This study identified diltiazem, a calcium channel blocker for hypertension, as a promising repurposed treatment for influenza, enhancing antiviral efficacy when combined with oseltamivir.

This review summarizes recent research and patents on 17β-HSD3, 17β-HSD5, and 3α-HSD3 inhibitors, suggesting their potential in treating androgen-dependent diseases, but reports no new clinical results.

This study suggests that both the central biosynthesis and metabolism of progesterone to 3α,5α‐THP in the ventral tegmental area are crucial for facilitating lordosis in female rats.

This review discusses the influence of oestrogens on various skin components and highlights their modulatory roles and receptor pathways, but it reports no new clinical results.

This review discusses various targets for treating prostate cancer and benign prostatic hyperplasia and reports on recent studies of new compounds and 5α-reductase inhibitors, but provides no new experimental results.

This study suggests that fish oil, specifically its components EPA and DHA, play a beneficial role in promoting skin health by supporting epidermal growth and reducing proinflammatory cytokines.

This study reports that in human glioblastoma and neuroblastoma cell lines, 24-hydroxycholesterol significantly suppressed the conversion of testosterone to growth-inducing androgens via the 5α-reductase pathway, revealing a new connection between cholesterol homeostasis and androgen metabolism.

The study found that social isolation in mice increases the sensitivity of their hippocampal synapses to ethanol's inhibitory effects on long-term potentiation, an effect preventable by finasteride.

In this study, baicalin from Scutellaria baicalensis decreased androgen levels in both cells and PCOS model rats by inhibiting key gene expression, suggesting it may be a potential treatment for hyperandrogenism in PCOS.
