The study aimed to identify new hair growth inducers by analyzing gene expression during hair growth induction in mice treated with cyclosporin A (CsA). Using DNA microarray analysis, researchers observed changes in gene expression related to melanin biosynthesis, immune response, cell proliferation, and hair-specific keratins. By employing connectivity mapping (Cmap), they identified agents with similar gene signatures to CsA-treated mice. Fluphenazine, identified from the d 2 signature, successfully induced hair growth in vivo, and its effect was enhanced by iloprost from the d 4 signature. The study demonstrated that Cmap analysis effectively linked gene expression profiles to potential hair growth-inducing agents.

The study demonstrated that MT-DADMe-ImmA, a potent inhibitor of MTAP, effectively induced apoptosis in head and neck cancer cell lines FaDu and Cal27 by increasing MTA levels and decreasing polyamines, leading to mitochondrial changes and activation of caspases. This treatment selectively targeted cancer cells without affecting normal fibroblasts, suggesting its potential as a cancer treatment. In a mouse model, MT-DADMe-ImmA led to tumor remission, highlighting its promise for cancers sensitive to DNA methylation changes. Despite inducing apoptosis, the treatment did not alter the protein levels of mitochondrial markers Bcl2 and Bax.

The study investigated the effects of deleting the first cut repeat domain of the Cux/CDP homeoprotein gene in mice. Researchers created a mutant form of the protein with an internal deletion of 246 amino acids, leading to a phenotype with curly vibrissae and wavy hair. Additionally, there was a high degree of pup loss in litters from mutant females, likely due to nutritional issues. The mutant protein was present at slightly higher levels than the wild-type and maintained normal tissue distribution and affinity for target sequences. The findings suggested that different DNA binding domains of the Cux/CDP protein regulated various genes in diverse tissues during development.

The study focused on a large Indian family with 127 members, including 41 affected by Clouston syndrome, an autosomal dominant disorder characterized by alopecia, dysplastic nails, and hyperkeratosis. Researchers used DNA polymorphisms for linkage analysis and confirmed linkage to the 13q11-12.1 region with a maximum lod score of 3.27, suggesting the gene responsible for Clouston syndrome in this family is likely the same as that identified in French-Canadian families. The findings indicated that combining data from all families linked to this region could help narrow down the critical area for positional cloning of the gene.
