Project description:RUNX1-ETO knockdown was performed in Kasumi-1 cells and transcriptomic analyses by RNA-sequencing were performed at two different time points (day2 and day9). Control cells (Kasumi-1 shControl) were also analysed at day2 and day9. All samples were analysed in triplicates.
Project description:Samples of adherent and suspension cells undergoing reprogramming were collected at day 0, day2, day6, day15 (with doxycycline) and day25 (without doxycycline).
Project description:Testis-specific transcript 10 (Tex10) is highly expressed in the testis, embryonic stem cells (ESCs), and primordial germ cells (PGCs). We previously generated a Tex10 knockout mouse model demonstrating its critical roles in ESC pluripotency and preimplantation development. Here, using conditional knockout mice and dTAG-degron ESCs, we show Tex10 is required for spermatogenesis and ESC-to-PGCLC differentiation. Specifically, Tex10-null spermatocytes arrest at metaphase I, compromising round spermatid formation. Tex10 depletion and overexpression compromise and enhance ESC-to-PGCLC differentiation, respectively. Mechanistically, bulk and single-cell RNA sequencing reveals that Tex10 depletion downregulates genes involved in pluripotency, PGC development, and spermatogenesis while upregulating genes promoting somatic programs. Chromatin occupancy study reveals that Tex10 binds to H3K4me3-marked promoters of Psmd3 and Psmd7, negative regulators of Wnt signaling, and activates their expression, thereby restraining Wnt signaling. Our study identifies Tex10 as a previously unappreciated factor in spermatogenesis and PGC development, offering potential therapeutic insights for treating male infertility.
Project description:In order to identify potential mechanisms involved in cardioprotection by IGF1 we performed microarray analysis of the infarcted areas on day1, day2, and day7 after acute myocardial infarction.
