This study provides the first direct evidence that spermidine can stimulate hair growth and modulate human epithelial stem cell biology in cultured human hair follicles.

This study proposes a model describing the transformation process from living to dead cells during early hair formation, highlighting the stepwise degradation of cellular functions.

This study reported the first known case of tertiary hypothyroidism in a dog, diagnosed after a Labrador treated for hyperadrenocorticism presented with related symptoms and an MRI-revealed pituitary mass.

In this study, animal model observations suggested that GLI1 expression may reduce cSCC initiation but is not involved in the tumor's aggressiveness.

This chapter reviews signaling pathways related to androgenic alopecia in dermal papilla cells of balding human scalps, integrating published information and analysis of molecular interactions, without reporting new clinical results.

This study found that some white or grey hairs can naturally regain pigmentation, suggesting hair greying may be reversible in certain conditions linked to psychological stress.

This study revealed that hair cells undergo an organized process to become keratin-packed "zombie" cells, highlighting a key area for treatment development in the first 1mm of hair follicles.

This chapter reviews studies on the side effects of cytostatics and immunosuppressive drugs, detailing various toxicities such as cardiovascular, pulmonary, and neurotoxicity, but provides no new clinical results.

This study found that epidermal growth factor treatment in male mice delayed normal skin development, inhibiting hair growth and follicle development by maintaining birth-level cell proliferation and differentiation for several days.

This study suggests that degraded human hair shafts are highly resistant to contamination by exogenous DNA, making them a valuable source for forensic and ancient DNA analysis.

This study found that minoxidil provides cardioprotective effects in guinea-pig heart cells through selective activation of mitochondrial ATP-sensitive potassium channels.

This review discusses the role of reactive oxygen species in wound healing, highlighting potential strategies like mitochondrial-targeted antioxidants for managing non-healing chronic wounds, and reports no new clinical results.

This study found that transient mtDNA double strand breaks in mice accelerated aging in certain tissues through increased reactive oxygen species, independent of p21/p53 pathway mediation.

This study found that FLCN deficiency in mice muscles led to increased mitochondrial biogenesis and a metabolic shift towards oxidative phosphorylation, with a similar advantage observed in FLCN-null kidney cancer cells.

Mitoxantrone is effective for treating acute leukemia, especially in older patients, with a lower risk of heart damage.

This research studied the effect of local testosterone propionate applications on rabbit epidermal mitotic activity but reports no new results.

In this study, researchers demonstrated that in a mouse model, the stimulation of mammary tumor growth due to progesterone is primarily caused by its metabolite, 5αP, not progesterone itself.

This review examines the role of P-cadherin in skin and hair biology, emphasizing its importance in human hair growth, cycling, and pigmentation, and reports no new research findings.

This study found that dapagliflozin enhanced mitochondrial quality control and adaptive autophagy in human cardiomyocytes under hypoxic stress, suggesting that these mechanisms may contribute to the cardioprotective effects of sodium-glucose cotransporter 2 inhibitors in ischemic injury.

This study suggests that cedrol may improve mitochondrial function, gut microbiota, and intestinal barrier integrity, indicating its potential value in treating inflammatory bowel disease.

This study observed that feeding ewes a water-soluble complex of fatty acids increased primary hair follicle bulb diameter and mitotic activity, suggesting a positive correlation with wool growth.

Mitochondria may influence how cells respond to radiation, affecting nearby non-irradiated cells.

This study demonstrated that dominant mutations in mouse gasdermin A3 disrupt mitochondrial oxidative stress regulation, suggesting a gain-of-function effect on epidermal differentiation.

In this study, researchers found that depleting mtDNA in mice caused skin wrinkles and hair loss but restoring mitochondrial function reversed these effects, highlighting mtDNA's significant role in skin and hair health.

Mitoxantrone with a corticosteroid helps manage symptoms for some advanced prostate cancer patients but doesn't extend life.

This study found that ZDHHC13 deficiency in mice is associated with abnormal liver function, lipid metabolism issues, and impaired mitochondrial function, highlighting ZDHHC13's regulatory role in liver metabolism.

This study found that oxidative damage is present in the mitochondria of PolG mice, which exhibit premature aging-like phenotypes due to mitochondrial dysfunction.

This study found that 62% of neutered dogs with hair cycle arrest experienced partial to complete hair re-growth after melatonin treatment, but hair re-growth was not consistently linked to normal sex hormone levels.

This study found that phosphatidic acid promotes hair growth by stimulating cell proliferation and protecting against apoptosis in murine hair epithelial cells, unlike lysophosphatidic acid, which showed limited effects.

Martin-Perez et al. show that rapamycin's beneficial effects in a mouse model of Leigh syndrome are linked to the downregulation of protein kinase C.
