Pantoea latae strain AS1 was isolated from the rhizophere of a cycad, Zamia floridana, in central Florida, USA. Here, we report the de novo whole-genome sequence of this strain, which consists of a total of 83 contigs spanning 4,960,415 bp, with a G+C content of 59.6%, and comprising 4,527 predicted coding sequences. ...[more]
Project description:ASYMMETRIC LEAVES 1 (AS1) is an important transcription factor for leaf development in Arabidopsis. But how it regulates downstream genes is largely unknown. We found a co-factor of AS1, LIKE HETEROCHROMATIN PROTEIN 1 (LHP1), also named as TERMINAL FLOWER 2 (TFL2), a PcG protein in Arabidopsis. To further investigate how AS1 and LHP1 co-regulate downstream genes at the genome level, we perform the transcriptome analysis of as1-1, tfl2-1, and as1-1 tfl2-1 in comparison with wild type (WT). Overall design: 12-day-old seedlings of wild-type (WT), as1-1, tfl2-1 and as1-1 tfl2-1 grown in normal growth condition were used for RNA extraction and microarray. Duplicate samples were analyzed.
Project description:Prostate cancer is the most common cancer in men and AR downstream signalings promote prostate cancer cell proliferation. We identified a novel androgen-regulated long non-coding (lnc) RNA, SOCS2-AS1. In order to investigate the SOCS2-AS1 function in prostate cancer cells, we performed gene expression in AR-positive prostate cancer cell lines (LNCaP and LTAD) after siSOCS2-AS1 or siSOCS2 treatment. We also treated cells with vehicle or androgen to analyzed the effects of siSOCS2-AS1 on AR function. Observation of androgen dependent gene expression changes after treatmet with siSOCS2-AS1 with microarray.
Project description:Analysis of tiling array data identified 358 genomic regions commonly enriched by the AS1 and T7 antibody datasets. AS1 antibody data set (AS1 antibody versus mock) and the T7 antibody data set (T7 antibody versus mock)
Project description:Long noncoding RNA (lncRNA) play important roles in the pathogenesis of cancer. LncRNA SBF2-AS1is unregulated in lung cancer tissues, while its biological function and molecular mechanism are largely unknown. RNA sequencing results suggest cell cycle-related genes are altered after SBF2-AS1 knockdown. In vivo and in vitro experiments confirm SBF2-AS1 could promote tumorigenesis of lung cancer. Further experiments prove SBF2-AS1 could bind with miR-338-3p and miR-362-3p to regulate various cell cycle-related genes, including E2F1. These results indicate the existence of ceRNA network driven by SBF2-AS1 through sponging miRNAs. Overall design: A549 cells are plated into 6-well plate and then transfected small interfering RNA (siRNA) specifically targeting SBF2-AS1 or negative control (NC) siRNA. 24 hours after transfection, cells are harvested and extract total RNA with TRIZol reagent.
