research Transient mitochondrial DNA double strand breaks in mice cause accelerated aging phenotypes in a ROS-dependent but p53/p21-independent manner
Damaging mitochondrial DNA in mice speeds up aging due to increased reactive oxygen species, not through the p53/p21 pathway.
research Ovarian sex steroid receptors and sex hormones in androgenized rats
High doses of nandrolone decanoate disrupt ovarian hormones and receptors in rats, with recovery only at lower doses and longer recovery times.
research EP-2271: The role of mitochondria in the non-targeted effect of ionizing radiation
Mitochondria may influence how cells respond to radiation, affecting nearby non-irradiated cells.
research P6590Androgenic effects on ventricular repolarization: a translational study from pharmacovigilance databases to iPSC-cardiomyocytes
Androgen-deprivation therapies increase the risk of certain heart conditions, but testosterone treatment may help.
research Hair Regeneration by Small Molecules That Activate Autophagy
Certain small molecules that trigger cell cleanup processes can promote hair growth.
research METABOLISM AND ACTION OF ANDROGEN IN THE SKIN
Androgens affect skin conditions like acne and hair loss through specific biochemical pathways.
research Impact of Chemotherapeutic Drug on People living with Cancer
Fasting may reduce chemotherapy side effects.
research Mouse models with a disrupted PTHrP gene or a disrupted PTH gene (PTH−/− mice)
PTHrP is important for bone formation and may be targeted for osteoporosis treatment and longevity therapies.
research Testosterone metabolism in the skin. A review of its function in androgenetic alopecia, acne vulgaris, and idiopathic hirsutism including recent studies with antiandrogens
Testosterone affects hair loss, acne, and excessive hair growth, and antiandrogens can help treat these conditions.
research YAP1 promotes adipogenesis by regulating the negative feedback mechanism of the Hippo signaling pathway via LATS2
YAP1 helps fat cell formation by influencing the Hippo pathway.
research Enriching Proteolysis Targeting Chimeras with a Second Modality: When Two Are Better Than One
Adding a second method to PROTACs could improve cancer treatment.
research Different synaptic stimulation patterns influence the local androgenic and estrogenic neurosteroid availability triggering hippocampal synaptic plasticity in the male rat
The availability of certain hormones and specific stimulation patterns affect long-term synaptic changes in the male rat brain.
research 14. 膠原病患者における心理状態の統計学的観察(第45回 日本心身医学会東北地方会 演題抄録)
Suppressing ODC activity reduces tumor growth in hair follicles.
research BIOLOGICAL ACTIVITY OF ANTIANDROGENS
Antiandrogens may help treat conditions like excessive hair growth, prostate tumors, male baldness, and acne by blocking male hormone effects.
research Influence of feed restriction on the wool proteome: A combined iTRAQ and fiber structural study
Feed restriction in sheep leads to finer wool fibers but may reduce wool quality.
research STUDIES ON A SKIN CALCIFYING SYSTEM
Mild skin injury can trigger mineral deposits in rat skin, even without full calciphylactic response.
research P381 Kinetics of Titan cells generation and transcriptome modifications comparing three in vitro protocols
Three different methods were compared for creating Titan cells, a type of fungus cell. The OZ method made the most cells initially, but the number dropped quickly. The EB method also made a lot of cells, but the number also dropped. The AA method made fewer cells, but the number stayed steady. The methods also affected which genes were active in the cells.
research 316 Specialized ribosomes in human dermal fibroblast senescence
Specialized ribosomes affect aging in human skin cells.
research Genetic Upregulation of Activated Protein C Mitigates Delayed Effects of Acute Radiation Exposure in the Mouse Plasma
Activated protein C helps protect mice from long-term radiation damage.
research Marie Krogh's contributions to the study of thyroid physiology and pathophysiology
Marie Krogh advanced understanding of thyroid hormones' effects on metabolism.
research Alopecia in Crash Dieters
Crash dieting can cause hair loss due to severe calorie restriction.
research News & Notes
Loop diuretics may double bone loss in elderly men, finasteride lowers prostate cancer risk but may increase high-grade tumors, abarelix reduces testosterone quickly, and transdermal testosterone offers minimal sexual benefit for women.
research Systemic and Topical Factors Involved in the Production of Experimental Cutaneous Calcinosis11From the Institut de Médecine et de Chirurgie expérimentales, Université de Montréal, Montréal, Canada.
Cutaneous calcinosis can be induced in young animals using certain compounds, but only in specific areas and with high mortality.
research Clinical benefits and adverse effects of genetically-elevated free testosterone levels: a Mendelian randomization analysis
Higher free testosterone levels can increase bone density and decrease body fat but may raise the risk of prostate cancer, hair loss, and benign prostate enlargement.
research Recent advances in oxasteroids chemistry
New methods to make oxasteroids show promise for medical treatments like osteoporosis and breast cancer.
