Project description:Hoxc13 has been shown to be essential for proper hair shaft differentiation as Hoxc13 gene-targeted (Hoxc13tm1Mrc) mice completely lack external hair. Because of the phenotypic parallels to the Foxn1nu (nude) mutant mice, we tested whether Hoxc13 and Foxn1 act in a common pathway of hair follicle (HF) differentiation. We show that the alopecia exhibited by both the Hoxc13tm1Mrc and Foxn1nu mice is due to strikingly similar defects in hair shaft differentiation and that both mutants suffer from a severe nail dystrophy. These similarities are consistent with the overlap of Hoxc13 and Foxn1 expression patterns in the HF and nail matrix. DNA microarray analysis of scapular skin from Hoxc13tm1Mrc mutant (mut) compared to wild type (wt) mice identified Foxn1 as significantly down-regulated along with numerous hair keratin genes. This Foxn1 down-regulation apparently reflects the loss of direct transcriptional control by HOXC13 as indicated by our results obtained through co-tranfection and chromatin immunoprecipitation (ChIP) assays. Total number of samples was 6. The experiment was perfomed in triplicate involving 3 indendent wild type skin samples (sample 1, 2, and 3) and 3 independent mutant skin samples (sample 4, 5, and 6).

Project description:This study examines the potential of hair shaft proteomic analysis to delineate genetic relatedness. Proteomic profiling and amino acid sequence analysis provide information for quantitative and statistically based analysis of individualization and sample similarity. Protein expression levels are a function of cell specific transcriptional and translational programs. These programs are greatly influenced by an individuals genetic background, and are therefore influenced by familial relatedness as well as ancestry and genetic disease. Proteomic profiles should therefore be more similar among related individuals than unrelated individuals. Likewise, profiles of genetically variant peptides that contain single amino acid polymorphisms, the result of non-synonymous SNP alleles, should behave similarly. The proteomically-inferred SNP alleles should also provide a basis for calculation of combined paternity and sibship indices. We test these hypotheses using matching proteomic and genetic datasets from a family of two adults and four siblings, one of which has a genetic condition that perturbs hair structure and properties. We demonstrate that related individuals, compared to those who are unrelated, have more similar proteomic profiles, profiles of genetically variant peptides and higher combined paternity indices and combined sibship indices. This study builds on previous analyses of hair shaft protein profiling and genetically variant peptide profiles in different real-world scenarios including different human hair shaft body locations and pigmentation status. It also validates the inclusion of proteomic information with other biomolecular substrates in forensic hair shaft analysis, including mitochondrial and nuclear DNA.

Project description:TCQA promoted differentiation of hNSCs at least toward the neuronal lineage and suggests the possibility of using TCQA to promote neurogenesis. When differentiation is induced by growth factor withdrawal, decreased expression of stemness gene and increased expression of NSC fate-promoting genes can be observed. Therefore, we evaluated the effect of TCQA on global gene expression in hNSCs during differentiation at 24h to elucidate the neurogenesis-promoting effects of TCQA.

Project description:Hair follicles undergo recurrent cycling of controlled growth (anagen), regression (catagen), and relative quiescence (telogen) with a defined periodicity. Taking a genomics approach to study gene expression during synchronized mouse hair follicle cycling, we discovered that, in addition to circadian fluctuation, CLOCK-regulated genes are also modulated in phase with the hair growth cycle. During telogen and early anagen, circadian clock genes are prominently expressed in the secondary hair germ, which contains precursor cells for the growing follicle. Analysis of Clock and Bmal1 mutant mice reveals a delay in anagen progression, and the secondary hair germ cells show decreased levels of phosphorylated Rb and lack mitotic cells, suggesting that circadian clock genes regulate anagen progression via their effect on the cell cycle. Consistent with a block at the G1 phase of the cell cycle, we show a significant upregulation of p21 in Bmal1 mutant skin. While circadian clock mechanisms have been implicated in a variety of diurnal biological processes, our findings indicate that circadian clock genes may be utilized to modulate the progression of non-diurnal cyclic processes. To investigate the molecular control of hair follicle cycling, we profiled mRNA expression in mouse dorsal skin at multiple representative time points in the synchronized second postnatal hair growth cycle and in a depilation-induced hair growth cycle. For profiling of second synchronized and depilation-induced hair growth cycle, the same upper-mid region of dorsal skin was excised from C57BL/6 mice at representative postnatal days (P). The time points for second hair growth cycle are classified into different phases of the hair growth cycle based on established morphological guidelines as follow: early anagen (P23, P25), mid anagen (P27), late anagen (P29, P34), early catagen (P37, P39), mid catagen (P41), and telogen (P44). Depilation-induced hair growth cycle by applying wax/rosin mixture on the dorsal skin of seven-week old mice (all follicles in telogen) was performed on mice. The corresponding phases of the hair growth cycle at number of days following depilation (D) is as follow: early anagen (D3), mid anagen (D5), late anagen (D8, D12), and early catagen (D17). For each time point, multiple biological replicates were profiled, with each mouse dorsal skin separately hybridized to an Affymetrix array.

Project description:TCQA- and TFQA- treatments in NSCs showed the significant performance on improving neurogenesis compared with no- treatment NSCs. TCQA and TFQA‐ treatments in NSCs also had significant activation of ErbB signaling pathway, AKT and MAPK kinases. Among them, TCQA- treatment upregulated Myc gene when Jun was mediated in TFQA- treatment, which stimulated the functions of enhancing synaptic growth and neuron differentiation. We used microarrays to detail the global programme of gene expression underlying treatment and identified distinct classes of regulated genes during this process.
