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.

Recognizing minor skin lesions can help identify serious cancer syndromes.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

This article discusses the paradoxical effects of valproic acid on hair, reporting both drug-induced hair loss and the potential for hair growth when used topically, but presents no original research findings.

This case report describes a 36-year-old female patient with panhypopituitarism, experiencing severe adrenal insufficiency and thyroid hormone deficiency, which led to electrolyte imbalance, QT interval prolongation, and ventricular tachycardia; treatment stabilized her condition, underscoring the importance of hormonal evaluation in arrhythmia assessment.

This study found that the L457(3.43)R mutation in the human luteinizing hormone receptor increases phosphodiesterase activity, reducing hormonal response despite elevated basal cAMP levels.

This study on mice found that activating TRPML channels with MLSA1 promoted hair regeneration, accelerated hair cycle transition, and influenced human dermal papilla cells to secrete hair growth promoting factors while reducing hair growth inhibitors and oxidative damage.

In this case report, a 71-year-old woman with severe hyperandrogenism and virilization revealed a bilateral ovarian steroid cell tumor, confirmed after adnexectomy, resulting in normalized testosterone levels and improved hirsutism post-surgery.

This study found that the development of Merkel cell carcinoma from hair follicles in mice can be driven by in vivo reprogramming with ATOH1 and relies on p53 loss for progression.

This study reports that patients with specific MFN2 mutations, including p.Arg707Trp, exhibit significant upper body fat overgrowth with suppressed leptin production, suggesting tissue-selective mitochondrial dysfunction and potential therapeutic targets.

This study found that conditional deletion of Mof in mice resulted in severe defects in skin development, including compromised epidermal differentiation and hair growth, leading to perinatal lethality.

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 case report highlights that macro-TSH, a rare condition causing falsely elevated TSH despite normal thyroid hormone levels, can lead to misdiagnosis and unnecessary treatment; identifying TSH antibodies and fractionation chromatography can prevent incorrect management, as demonstrated in a 19-year-old patient.

In this transgenic mouse study, preliminary findings suggest that overt melanocyte hyperplasia may require prior keratinocyte hyperplasia, indicating a potential role for keratinocyte mutation in early melanoma development.

In this case report, a 70-year-old woman with a history of autoimmune hypothyroidism experienced alternating hypothyroidism and hyperthyroidism over a decade, highlighting the potential role of thyrotropin receptor autoantibodies in these fluctuations.

In this case report, a 66-year-old postmenopausal woman with hyperandrogenism and alopecia underwent bilateral salpingo-oophorectomy, which revealed rare synchronous ovarian tumors causing virilization, highlighting the importance of surgical exploration despite normal imaging.

This case study reported hyperandrogenism in non-obese triplet sisters with one sister's hyperthyroidism masking its clinical and biochemical signs until treatment increased her androgen levels and hirsutism.

This case report details a diagnostic challenge in a postmenopausal woman with severe hyperandrogenism where distinguishing between adrenal and ovarian causes was complicated by elevated 17-OH Progesterone and asymmetric ovarian enlargement; pending surgical pathology is expected to guide further management.

This report describes a complex case of postmenopausal hyperandrogenism with virilization and concurrent rare ovarian tumors, highlighting the critical role of interdisciplinary collaboration in diagnosing and managing such challenging scenarios.

In this case report, a 62-year-old woman with hyperandrogenism and polycythemia was diagnosed with a rare ovarian steroid cell tumor, highlighting the importance of considering such tumors in similar presentations; surgical removal led to symptom and lab normalization.

This study found that overexpression of the mineralocorticoid receptor in a mouse model led to premature epidermal barrier development, keratinocyte apoptosis, and postnatal alopecia, indicating new roles for MR signaling in skin physiology.

In this study, selective overexpression of androgen receptors in muscle cells increased lean muscle mass and reduced fat mass in transgenic rodents, suggesting a potential target for drug development.

This study found that autophagy activation in hair follicle stem cells shifted their metabolism to glycolysis, which promoted hair growth by initiating the hair follicle cycle.

In this study, researchers found that inducing mitophagy can alleviate NLRP3 inflammasome activation in outer root sheath cells under conditions of mitochondrial stress, suggesting that targeting mitophagy and inflammasome interactions may offer new therapeutic approaches for alopecia areata.

In this study, the authors concluded that the TS-associated polyomavirus may disrupt Wnt/β-catenin signaling, likely contributing to abnormal hair follicle formation in trichodysplasia spinulosa.

Minoxidil can cause excessive hair growth.

This study found that transgenic mice overexpressing E2F1 in their epidermis developed skin tumors, confirming in vivo that deregulated E2F1 activity can contribute to tumor development.

This study in mice suggests that defects in hair follicles with mesenchymal TSC2 disruption may result from an impaired TGFβ1 response, indicating a potential novel treatment approach for tuberous sclerosis complex.

This study highlights that the mammalian target of rapamycin complex 2 (mTORC2)-Akt signaling axis is essential for hair follicle stem cells to return to their niche and regenerate effectively by regulating metabolic pathways.

This paper introduces a hypothesis that elevated DHT at puberty may increase cerebral heat output, creating chronic thermal stress linked to androgenetic alopecia, and suggests this could be tested with MR thermometry.
