Project description:We present the draft genome of Nitrospirae bacterium Nbg-4 as a representative of this clade and couple this to in situ protein expression under sulfate-enriched and sulfate-depleted conditions in rice paddy soil. The proteins were extracted from the soil and analysed via LC-MS/MS measurements.

Project description:Microbes play key roles in diverse biogeochemical processes including nutrient cycling. However, responses of soil microbial community at the functional gene level to long-term fertilization, especially integrated fertilization (chemical combined with organic fertilization) remain unclear. Here we used microarray-based GeoChip techniques to explore the shifts of soil microbial functional community in a nutrient-poor paddy soil with long-term (21 years).The long-term fertilization experiment site (set up in 1990) was located in Taoyuan agro-ecosystem research station (28°55’N, 111°27’E), Chinese Academy of Sciences, Hunan Province, China, with a double-cropped rice system. fertilization at various regimes.

Project description:Recent studies reveal that a subset of cancers in various indications are dependent on high and constant expression of certain transcription factors for growth and survival, a phenomenon termed as transcriptional addiction. Therefore, targeting transcriptional machinery can potentially lead to potent and selective anticancer effects. CDK7 is the catalytic subunit of the CDK-activating kinase (CAK) complex. Its function is required for both cell cycle regulation and transcriptional control of gene expression. CDK7 has recently emerged as an attractive target in cancer since its inhibition leads to decrease of the transcript levels of oncogenic transcription factors, especially those associated with super-enhancers (SEs). Here we describe a first-in-class CDK7 inhibitor SY-1365, which covalently targets a cysteine outside the kinase domain, resulting in sustained, highly selective inhibition of CDK7. In vitro studies reveal that SY-1365 has potency in a wide range of cancer models with low micromolar IC50 values. Cancer cells with low BCL-XL expression are found to be more dependent on MCL1 for survival and therefore particularly sensitive towards SY-1365 treatment since SY-1365 downregulates MCL1 protein level. SY-1365 treatment induces distinct transcriptional changes in acute myeloid leukemia (AML) cell lines. SY-1365 also demonstrates substantial anti-tumor effects in multiple AML xenograft models. Additionally, combination treatment with venetoclax shows synergistic effects in AML models both in vitro and in vivo. Our findings support targeting CDK7 as a new approach for treating transcriptionally addicted cancers. SY-1365 is currently being assessed in a Phase I trial in adult patients (NCT03134638) We performed microarray based expression profiling to quantify transcriptional changes upon treatment with the CDK7 inhibitor, SY-1365 and to compare it to transcriptional changes induced by treatment with other transcriptional drugs JQ1 (BRD4 inhibitor), NVP2 (CDK9 inhibitor) and flavopiridol (pan-CDK inhibitor). We profiled a human acute myeloid leukemia (AML) cell line THP-1. Cells were treated with either DMSO, 100nm SY-1365, 25nM NVP2 , 250nM JQ1 or 200nM flavopiridol for two and six hours. All samples were prepared in biological triplicate.

Project description:Paddy rice with husk can be availbale for chicken dietary resource instead of yellow corn. Ingestion of paddy rice potentially affects on gastrointestinal physiology and function including digestion/absorption of nutrients and gut barrier function such as mucosal immunity, but the details of changes is unknown. To obtain insight into the physiological modifications in the small intestine of chickens fed paddy rice, we conducted a comprehensive analysis of gene expression in small intestine by DNA microarray. In the paddy rice group, a total of 120 genes were elevated >1.5-fold in the paddy rice group, whereas a total of 159 genes were diminished < 1.5-fold. Remarkably, the gene expression levels of IGHA (immunoglobulin heavy chain α), IGJ (immunoglobulin J chain), and IGLL1 (immunoglobulin light chain λ chain region), which constitute immunoglobulin A, decreased 3 to 10 times in the paddy rice group.
