Humans lost body hair relatively recently in evolution.

This study found that the combination of letrozole and quercetin loaded in spanlastics showed enhanced cytotoxicity and other anticancer effects against MCF-7 breast cancer cells compared to individual treatments.

This study suggests that activating AMPK to phosphorylate ZDHHC13 may enhance MC1R function and reduce melanoma risk in individuals with red hair.

This study reported that patients with alopecia areata have reduced expression of the melanocortin receptor MC2R in their scalp tissues compared to normal scalp, indicating potential involvement in the condition's pathophysiology.

In this study, researchers found that caffeine can counteract stress-induced damage in ex vivo human androgenetic alopecia hair follicles, suggesting it may help prevent stress-related hair loss.

This study found that two MC4R gene polymorphisms are associated with higher BMI in women with PCOS in western Saudi Arabia, but are not linked to PCOS itself.

MC4R gene variants not linked to female hair loss.

This study found that in estrogen receptor-positive breast cancer cells, 17β-estradiol repressed polyamine oxidase transcription by interacting with AP-1 sites on its promoter.

In this study, oral contraceptive use in women with PCOS increased the expression of certain inflammatory gene markers, which were positively associated with metabolic abnormalities.

In this study, researchers found that women with telogen effluvium had lower MCV/RDW ratios, MPV, and ferritin levels compared to healthy controls, suggesting iron deficiency's involvement in this chronic hair loss condition.

This study found that the secretory profiles of adipose-derived stem cells vary between balding and non-balding scalp areas in androgenetic alopecia patients, suggesting involvement of angiogenic and inflammatory processes in the condition's development.

This study found that the ACTH/MC2R system is important for hair cycle regulation, with deficiencies in MC2R leading to altered hair growth phases in mice.

This review discusses the role of the MC1R gene in human pigmentation and its genetic variants, reporting no new results; the authors highlight its forensic applications for phenotypic prediction.

This study observed that since the onset of COVID-19 and the introduction of vaccines, there has been an increase in chronic, severe health conditions, with symptoms affecting both those infected with COVID variants and vaccinated individuals, especially those receiving Pfizer and Moderna vaccines.

This study found that, despite confirming MC1R expression and functional cAMP signalling, α-MSH treatment did not alleviate UVA-induced stress in adult dermal fibroblasts, suggesting that α-MSH-MC1R may not directly protect against UVA-induced photoaging in these cells.

This paper provides correct answers and explanations for multiple-choice questions related to epilepsy, but does not present new research findings.

This case report describes an 8-year-old girl with Mixed Connective Tissue Disease who experienced remission after treatment with immunomodulator drugs, highlighting the diagnostic value of anti-U1 RNP antibody testing in children.

In this case study, researchers documented a Chinese boy with hair color changing to red and identified MC1R genetic mutations as the cause, rather than zinc deficiency, enhancing our understanding of hair heterochromia due to genetic factors.

In a mouse model study, researchers observed that the absence of MCPIP1 in myeloid cells decreased susceptibility to chemically induced skin papillomas but caused significant hair loss and skin pigmentation changes, suggesting a role for MCPIP1 in skin carcinogenesis and follicle integrity.

In this study, mice lacking the Mcpip1 gene in their myeloid cells did not develop SCC-like tumors but instead showed increased melanocyte activity and hair loss, indicating a distinct role for myeloid Mcpip1 in skin cancer development compared to keratinocyte Mcpip1.

This review investigates the relationship between certain gene polymorphisms associated with obesity (FTO and MC4R) and Polycystic Ovarian Syndrome, reporting no new results but suggesting a potential genetic link.

In this study, a clear pattern of selective sweep was observed for the SLC24A5 gene, with high linkage disequilibrium and low haplotype diversity, but no clear correlation with UV radiation intensity was found.

This study examined the expression of fatty acid transporters and binding proteins in mouse sebaceous glands and found that CD36 did not affect the localization of other related molecules.

In this case report, tamoxifen-induced hirsutism was observed in a young girl with McCune-Albright syndrome shortly after starting treatment.

This study suggests that Mcl-1 has a non-apoptotic role in promoting keratinocyte proliferation and Wnt/β-catenin signaling, potentially indicating a novel oncogenic activity.

This study found that CMV infection in a mouse model of allogeneic transplantation was associated with increased allo-reactive T cell expansion and exacerbated graft-versus-host disease, highlighting the need for effective GvHD prophylaxis and treatment.

This study found that adipose derived stem cells in areas of alopecia in patients with androgenetic alopecia showed different levels of various signaling proteins compared to other scalp and periumbilical regions.

This study found that Oncostatin M, via JAK-STAT5 signaling, keeps hair follicle stem cells inactive, and its removal leads to hair growth initiation in mice.

This study found that systemic administration of NDP-MSH, a melanocortin receptor agonist, provided neuroprotective effects on dopaminergic nigrostriatal neurons in a mouse model of Parkinson's disease, reducing neuroinflammation and suggesting a role for regulatory T cells in these neuroprotective effects.

High MUC-18/MCAM levels in blood indicate a worse outlook for melanoma patients.
