In this study, researchers found that the efflux of calcium in root hairs of Arabidopsis thaliana, particularly through the ER-localized ACA2 and ACA7, is crucial for modulating cytoplasmic calcium signals and enabling proper root hair growth, with disruptions leading to impaired elongation.

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.

This study found that patients with acne vulgaris had higher serum IGF-1 levels and more intense FoxO1 and mTOR expression than controls, suggesting their role in acne pathogenesis.

This study demonstrates that c-MYC overexpression in sebaceous glands affects differentiation via a regulatory axis involving the androgen receptor and p53, influencing carcinoma formation outcomes.

In this study, researchers showed that the CAP1 gene regulates root hair growth in plants by modulating cytoplasmic ammonium levels and maintaining calcium gradients, highlighting its role in ammonium homeostasis.

This study found that carbonic anhydrase II was significantly upregulated in human keratinocytes when treated with toll-like receptor 3 agonist and Th2 cytokines, suggesting its potential role in inflammatory skin conditions.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This study found that overexpressing PLC5 in Arabidopsis thaliana reduced root growth but improved drought tolerance, and suggests PIP2 is crucial for root hair growth.

This study found that interleukin-1 directly induces the expression of keratin 6 in keratinocytes, which is a marker of activation and involved in inflammatory skin responses.

This study found that certain metabolites from the plants Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana may support hair follicle growth by promoting dermal papilla cell proliferation, supporting their traditional use in hair care.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

In this study using human cell cultures, type 1 5α-reductase was found to vary in both protein heterogeneity and expression levels across different types of skin cells.

In this study, researchers found that specific mutations in iRhom2 in mice lead to skin and hair abnormalities which depend on the presence of the protein ADAM17, suggesting a complex role for iRhom2 in tissue development and potential implications for treating tylosis with oesophageal cancer.

This study found that activating Toll-like receptor 3 signaling in periodontal ligament stem cells may enhance their immunomodulatory properties, suggesting potential implications for future stem cell therapy applications.

In this study, overexpression of YAP1 was found to promote adipogenic differentiation of goat adipose-derived mesenchymal stem cells by up-regulating LATS2 expression and activating the Hippo pathway's negative feedback loop.

This study found that cephalanthine inhibited the growth of gastric cancer cells in vitro and in vivo by inducing oxidative stress and altering energy metabolism, suggesting its potential as a treatment for gastric cancer.

In this study, copper was found to promote the proliferation of dermal papilla cells in Rex rabbits by maintaining the function of the cellular mitochondrial electron transport chain.

This study demonstrated that AtVLN4 plays a role in root hair growth by regulating actin organization in a calcium-dependent manner.

This study found that plasma cardiac troponin I levels were highest in subjects with alopecia areata, potentially indicating increased heart remodeling and a need for close cardiovascular monitoring in these individuals.

This study observed significant clinical effects, such as hair loss and testicular changes, in common quail treated with the steroids IVF-C Inj and Diane-35, especially highlighting cyproterone acetate's impact on vital organs like the liver.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This study found that direct interactions between human dermal papilla cells and melanocytes under low oxygen conditions improved cell functions and could be important for hair regeneration efforts.

This study found that restoring hypothalamic NPY levels in mice delayed aging-related characteristics such as fat loss, hair loss, and memory decline, suggesting that maintaining these levels could be important for counteracting aging and its effects.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

This study found that inhibiting PKC-β activity with bisindolylmaleimide reduces pigmentation in the skin and hair of guinea pigs and mice by preventing tyrosinase activation.

This study found that low-level laser therapy effectively reduced relapse rates, while functional appliances did not; combining them offered no additional benefits.

This study found that Ca²⁺ signaling and peptidylarginine deiminase enzymes play a crucial role in activating neural stem cells in response to injury in zebrafish, suggesting potential therapeutic targets for CNS injuries and cancer.

In this study, a novel mutation in the glucocorticoid receptor gene was identified in a young woman, impairing glucocorticoid signaling and leading to generalized glucocorticoid resistance.

This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.
