Project description:19 female mice of the C57BL/6J and B6D2F1N strains were housed in either standard (control) or enriched (including access to playgrounds) conditions. The animals were trained to perform a cognitive judgement bias test. Upon completion of training, the animals underwent the test paradigm and were sacrificed. Anterior and posterior portions of the amygdala were finally dissected for RNA-sequencing.
Project description:This study provides a comprehensive proteomic analysis of five matched pairs of the anterior and posterior lobe of the pituitary, which was used to study the proteomic signature specific to both anterior and posterior lobes. Anterior Lobe n=5 Posterior Lobe n=5 A441 PT441 A442 PT442 A457 PT457 A459 PT459 A460 PT460
Project description:Shh signal mediated by Gli family of transcription factors regulates digit growth and patterning in early limb development. Shh expression in the posterior margin of the limb bud defines the zone of polarizing activity. However, much less is know about downstream targets that mediate Shh signal functions. In this dataset, we include the expression data obtained from dissected anterior and posterior halves of mouse limb bud respectively. These data are used to obtain 889 transcripts that were upregulated 1.3 fold or more in the posterior limb bud, and 1189 transcripts that were enriched in the anterior limb bud at 1.3 fold or more. Two samples were analyzed. We generate pairwise comparisons between anterior and posterior limb tissues. Genes with a fold-change ≥1.3 were selected.
Project description:To investigate whether male MPN- and VMHvl-projecting neurons in posterior amygdala have distinct transcriptional profiles, we conducted RNAseq onto these subpoplations that were microdissected by laser capture microdissection. Our results demonstrate that each subpoplations had largely distinct set of enriched genes.
Project description:We profiled the transcriptome of anterior and posterior zebrafish Vagus motor neurons at 28-30 hours post fertilization to identify genes that are differentially expressed between these two cell populations.
Project description:We report the continuous patterning and dynamic morphogenesis of hepatic, biliary and pancreatic structures, invaginating from a three-dimensional culture of human pluripotent stem cell (PSC). The boundary interactions between anterior and posterior gut spheroids differentiated from human PSCs enables autonomous emergence of hepato-biliary-pancreatic (HBP) organ domains specified at the foregut-midgut boundary organoids in the absence of extrinsic factor supply. The regional identity of the boundary region of anterior-posteior spheroids was analyzed by RNA-sequencing with micro-dissected boundary organoid into anterior, posterior, and boundary regions. Each region expressed the corresponding gut lineage markers. The early HBP specification markers including HHEX1 and PDX1 at the boundary were highly upregulated compared with the other two regions, indicating that the anterior-posterior boundary interactions autonomously generate HHEX and PDX1 positive cells in the absence of exogenous inductive factors. To delineate the HBP progenitor self-inductive mechanism, we evaluated the boundary specific expression profiles of known inductive signaling pathways that includes FGF, BMP, Hedgehog, NOTCH and retinoic acid (RA) signals, and found that the signal downstream of RA were activated prominently at the boundary region but not in the anterior or posterior regions.
Project description:Postnatal neuroblasts were microdissected by laser micro dissection from posterior and anterior rostral migratory stream (RMS). Neuroblasts in the posterior RMS are just started their migration. Neuroblasts in the anterior RMS are already migrated for several days in the stream
Project description:The transcriptomes of immortalized anterior and posterior limb cell lines derived from E10.5 embryos were compared. Total RNA extracted from three E10.5 anterior and posterior limb cell line samples were compared.
