This article reviews cytokeratin expression patterns in epithelial tissues and tumors, suggesting these patterns can aid in differentiating primary and metastatic carcinomas, without presenting new clinical results.

This study found that Epstein-Barr virus infection upregulated a truncated variant of human basic hair keratin 1 (hHb1-ΔN) in gastric carcinoma cell lines, suggesting a possible link to carcinoma differentiation.

This case report describes a 36-year-old woman with hidradenitis suppurativa whose condition progressed to rapidly fatal squamous cell carcinoma, highlighting the potential for aggressive tumor development linked to specific protein markers.

This report describes a rare case of elevated serum DHEAS levels in a postmenopausal woman, linked to an ovarian sex cord-stromal tumor rather than the adrenal glands, challenging common assumptions about androgen sources.

This article reports two cases where ovarian hyperthecosis caused hyperandrogenism in postmenopausal women, confirmed by imaging and resolved after bilateral oophorectomy.

In this case study, a 71-year-old woman with postmenopausal hirsutism was diagnosed with a Leydig cell tumor and endometrial carcinoma, with hirsutism improving one month after surgery.

This study found that Neuregulin3 can influence the development and differentiation of mammary glands and epidermal features in mice, potentially by inducing c-Myc and altering cell proliferation and adhesion.

This study found that multiphoton microscopy imaging allows for detailed observation and quantitative analysis of collagen alterations in the progression of endometrial cancer, potentially offering a faster, more accurate method for early diagnosis compared to current protocols.

This letter reports a woman with nevoid basal carcinoma syndrome and pronounced androgenic alopecia associated with a novel PTCH gene mutation p.Leu1159fsx32, suggesting a genetic link in this case study.

This study found that the truncated hHb1-DeltaN transcript in breast cancer cells is produced by a cryptic intron promoter and responds to DNA demethylation, potentially altering cancer cell adhesion.

This study identified the c.1204G to A (p.E402K) mutation in the hHB6 gene as a cause of monilethrix in a Chinese family, highlighting the gene's role in the condition.

This study found that super-enhancers in squamous cell carcinoma stem cells are distinctly different from those in normal skin stem cells, with ETS2 playing a crucial role in promoting tumor growth.

This study reported that immortalizing human dermal papilla cells using HPV16 E6/E7 oncogenes increased their proliferation and maintained their hair follicle formation capability, potentially facilitating in vitro hair growth and regeneration research.

This proof-of-concept study reported that a new, ultra-fast, one-step immunohistochemistry method improved the interpretation of Mohs surgery slides, particularly for poorly differentiated tumors.

This study describes a functional disorder in the ovary, known as stromal hyperplasia, characterized by the proliferation of ovarian stroma and luteinization of stromal cells, which is linked to excessive androgen production and elevated testosterone levels.

This systematic review found that mixed epithelial and stromal tumor of the seminal vesicle (MESTSV) is characterized by abundant stromal proliferation, architectural heterogeneity, and strong immunoreactivity for ER/PR, with most being benign but warranting surveillance for possible recurrence or metastasis.

This case report identified ovarian hyperthecosis as the cause of recent-onset androgenic symptoms in a 73-year-old woman, which was confirmed by ovary removal and led to symptom improvement.

This study reported that the PTGER2 gene is strongly expressed in cashmere goat skin and its expression tends to decrease from the anagen to telogen stages of the hair follicle cycle.

A new mutation in the HR gene causes hair loss in a specific family.

In a mouse model of chemotherapy-induced alopecia, this study found that enhancing ETV2 expression improved angiogenesis and hair regrowth following 5-fluorouracil treatment.

This study found that targeting HSP70 can suppress basal cell carcinoma growth, underscoring the importance of tumor microenvironment interactions in cancer progression.

This review discusses androgen receptor targeting as a potential treatment strategy for triple-negative breast cancer and reports no new experimental outcomes.

In this case report, a 55-year-old postmenopausal woman was diagnosed with ovarian hyperthecosis as the cause of her hyperandrogenism after detailed hormonal and imaging investigations, which was successfully treated with bilateral salpingo-oophorectomy, leading to symptom improvement and normalized testosterone levels.

This study reported that NRP2 expression in melanocytes and melanocyte stem cells is linked to migration inhibition and potentially melanoma progression, suggesting its role as a target for understanding melanoma and hair follicle biology.

This study reports that high expression of proteins ST14 and TMEFF1 in ovarian cancer correlates with higher tumor malignancy and worse prognosis, and reveals an interaction where ST14 regulates TMEFF1 to promote cancer cell proliferation, migration, and invasion.

This study examined a case of postmenopausal virilization in a woman and found that despite normal imaging, bilateral salpingo-oophorectomy revealed rare ovarian Leydig cell and Brenner tumors as the source of hyperandrogenism, with symptoms resolving post-surgery.

This study found that colorectal cancer patients could be categorized into two groups based on mitochondrial-related gene features, with distinct survival outcomes and tumor microenvironment characteristics, suggesting these features could inform individualized treatment plans.
