research Topical Janus Kinase Inhibitors for the Treatment of Pediatric Alopecia Areata
Topical JAK inhibitors may help children with alopecia areata regrow hair.
research Neural Potential of a Stem Cell Population in the Hair Follicle
The study investigated the neural potential of stem cells in the bulge region of hair follicles using nestin-GFP mice. These cells demonstrated multipotency, capable of differentiating into various cell types, including neuronal, astrocytic, and oligodendrocytic cells, both in vitro and in vivo. Transcriptional profiling revealed a unique gene expression signature, indicating a distinct population of multipotent stem cells with broad differentiation potential. The research showed that these cells could form "hairspheres" and differentiate into neurons, astrocytes, smooth muscle-like cells, and keratinocytes under specific conditions. In vivo experiments confirmed their neural potential by successful differentiation into neuronal cells upon transplantation into chick embryos. The findings highlighted the plasticity of adult tissue-specific stem cells, challenging previous notions about their limited differentiation capabilities and suggesting their potential to contribute to both ectodermal and mesodermal lineages.
research Two Distinct Signaling Pathways in Hair Cycle Induction: Stat3-Dependent and Independent Pathways
There are two ways to start hair growth: one needs Stat3 and the other does not, but both need PI3K activation.
research Two Hydroxyproline Galactosyltransferases, GALT5 and GALT2, Function in Arabinogalactan-Protein Glycosylation, Growth, and Development in Arabidopsis

research 9-cis-Retinoic Acid Capsules in the Treatment of AIDS-Related Kaposi Sarcoma
9-cis-retinoic acid showed some effectiveness in treating AIDS-related Kaposi sarcoma but had significant side effects at higher doses.
research Ornithine Decarboxylase Expression Leads to Translocation and Activation of Protein Kinase CK2 In Vivo
The study investigated the impact of ornithine decarboxylase (ODC) overexpression on protein kinase CK2 activity and localization, revealing that elevated polyamine levels led to increased CK2 activity and its translocation from the cytoplasm to the nucleus. Despite a significant increase in CK2 protein levels, only a modest rise in enzyme activity was observed, with nuclear CK2 activity increasing 4-fold. In K6/ODC transgenic mice, high ODC activity in hair follicles resulted in hair loss and follicular cysts, suggesting a link between polyamine metabolism and cancer progression. The findings indicated that polyamines might regulate CK2 by affecting its distribution and activity, potentially contributing to tumor development by altering CK2 activity and disrupting normal signal transduction pathways.
research Androgen-Dependent Beard Dermal Papilla Cells Secrete Autocrine Growth Factors in Response to Testosterone Unlike Scalp Cells
Beard cells, unlike scalp cells, produce growth factors in response to testosterone, which may explain differences in hair growth.
