Granulosa cells (GCs) are essential somatic cells in the ovary and play an important role in folliculogenesis. Brain-derived neurotropic factor (BDNF) and the TGF-β pathway have been identified as a critical hormone and signalling pathway, respectively, in GCs. In this study, we found that a conserved microRNA family that includes miR-10a and miR-10b repressed proliferation and induced apoptosi...

In search of better NSAIDs four novel nitric oxide donating derivatives of curcumin (compounds 9a-d), and four thiophene curcuminoids (compounds 10a-c, 11) have been synthesised. The cytotoxic effects of these compounds along with the lead compound curcumin (7) and their effect on the production of the reactive oxygen species nitric oxide and pro-inflammatory cytokines IL-1β, TNF-α and chemokin...

Atrazine, a pre-emergent herbicide in the chloro-s-triazine family, has been widely used in crop lands and often detected in agriculture watersheds, which is considered as a potential threat to human health. Although atrazine and its metabolites showed an elevated incidence of mammary tumors in female Sprague-Dawley (SD) rats, no molecular evidence was found relevant to its carcinogenesis in hu...

BACKGROUND Acute kidney injury is a common clinical comorbidity and early diagnosis is crucial for improving prognosis, but there is still no ideal biomarker for early diagnosis. MATERIAL AND METHODS miRNA microarray was used for detecting miRNA in kidney subjected to renal ischemia-reperfusion injury 12 h after reperfusion. Real-time PCR was performed to validate the results of microarray. m...

We discovered that an inverse relationship exists in the expression of ras/c-myc and ribosomal protein RPS2 with pre-let-7a-1/let-7a/let-7f miRNA and prostate tumor cell malignancy. Nonmalignant IBC-10a cells expressed low levels of ras/RPS2 and elevated pre-let-7a-1/let-7a/let-7f miRNA, whereas the reverse occurred in malignant PCa-20a and PC-3ML cells. Stable transfection of IBC-10a cells wit...

There has been evidence of warming rate varying largely over space and between seasons. However, little has been done to evaluate the spatial and temporal variability of air temperature in the Tarim Basin, northwest China. In this study, we collected daily air temperature from 19 meteorological stations for the period of 1960-2012, and analyzed annual mean temperature (AMT), the annual minimum ...

In this study, a series of novel benzofuran-based 1,2,4-triazole derivatives (10a–e) were synthesized and evaluated for their inhibitory potential against acetylcholinesterase (AChE) bacterial strains (E. coli B. subtilis). Preliminary results revealed that almost all assayed compounds displayed promising efficacy AChE, while compound 10d was found to be highly potent inhibitor AChE. Similarly,...

Benzotiazole and pyrimidine have been reported to act as effective pharmacophores. However, much less work as been carried out on these heterocycles fused with each other. In the present study, we report the synthesis of a series of 8-chloro-3(phenylcarbonoimidoyl)-10a-H-pyrimido [2,1-b][1,3]benzothiazole-2-thiol. This series was synthesized by the reaction of 8-chloro-2-sulfanyl-10a-H-pyrimido...

PURPOSE There is a continuing need for genetically matched cell systems to model cellular behaviors that are frequently observed in aggressive breast cancers. EXPERIMENTAL DESIGN We report here the isolation and initial characterization of a spontaneously arising variant of MCF-10A cells, NeoST, which provides a new model to study cell adhesion and signal transduction in breast cancer. RESU...

This study aimed to identify and characterize microRNAs (miRNAs) that are related to radiosensitivity in low-grade gliomas (LGGs). The miRNA expression levels in radiosensitive and radioresistant LGGs were compared using The Cancer Genome Atlas database, and differentially expressed miRNAs were identified using the EBSeq package. The miRNA target genes were predicted using Web databases. Fiftee...
