Anthracycline/taxane-based chemotherapy regimens are usually used as neoadjuvant chemotherapies to decrease tumour size and prevent metastasis of advanced breast cancer. However, patients have a high risk of developing chemo-resistance during treatment through still unknown mechanisms. Glutathione S-transferase P1 (GSTP1), which belongs to the family of phase II metabolic enzymes, has been reported...
Chemoresistance mediated by miRNAs in breast cancer have been already validated by previous studies in vitro, while little is known concerning the expression of them in vivo. The aim of this study was to investigate the role of miR-222, miR-29a, miR-34a, miR-130a, miR-90b, miR-200b, miR-452, miR-197, miR-138, miR-210, miR-423, miR-4298, miR-4644, miR-139, miR-1246, miR-1268a, miR-140, miR-149, miR-3178,...
microRNAs (miRNAs) are small noncoding RNAs that could regulate post-transcription level through binding to 3′ untranslated region (3′UTR) of target messenger RNAs (mRNAs), which were reported to be related with the incidence and development of diverse neoplasms. Among them, miR-197 was confirmed to play a vital role of oncogene or anti-oncogene in different cancers via targeting key tumorigenic or...
Adriamycin (Adr) is a potent chemotherapeutic agent for chemotherapy of breast cancer patients. Despite impressive initial clinical responses, some developed drug resistance to Adr-based therapy and the mechanisms underlying breast cancer cells resistance to Adr are not well known. In our previous study, in vitro, we verified that miR-222 was upregulated in Adr-resistant breast cancer cells (MCF-7/Adr)...
To better understand the characteristics and the evolutionary dynamics of mt genomes in Arcidae, the complete mitochondrial genome of Tegillarca granosa was firstly determined and compared with other two Arcidae species (Scapharca broughtonii and Scapharca kagoshimensis). The complete mitochondrial genome of T. granosa was 31,589bp in length, including 12 protein-coding genes, 2 rRNA genes and 23...
MicroRNAs (miRNAs) are directly involved in cancer initiation, progression and metastasis. Alterations of miRNAs expression in cancer tissue may be reflected in circulation. We attempted to investigate the expression and clinical significance of plasma miR-20a, miR-31 and miR-375 in patients with non-small cell lung cancer (NSCLC). The plasma levels of miR-20a, miR-31 and miR-375 in 164 NSCLC patients...
The present study was designed to investigate the underlying molecular mechanism for Angiotensin II type 1 receptor blockers (ARBs) mediated cardio-protection against pressure overload-induced cardiac remodeling with a focus on Smad7. ROCK-1, Smad3 and fibronectin expressions were increased in male C57BL/6 mice underwent transverse aortic constriction (TAC) for 2weeks. Treatment with Candesartan (2mg/kg...
By analyzing the predicted gene expression levels of 33 prokaryotes with living temperature span from <10 °C to >100 °C, a universal positive correlation was found between the percentage of predicted highly expressed genes and the organisms' optimal growth temperature. A physical interpretation of the correlation revealed that highly expressed genes are statistically more thermostable than lowly...
