Germline-specific genes, Vasa, Dazl and Nanos1, have highly conserved functions in germline development and fertility across animal phyla. In this study, the full-length sequences of Opvasa, Opdazl and Opnanos1 were cloned and characterized from the dark sleeper (Odontobutis potamophila). Gonad-specific expression patterns of Opvasa and Opdazl were confirmed in adult tissues by quantitative real-time...
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...
MicroRNAs (miRNAs) are a class of highly conserved small noncoding RNAs that play pivotal roles at the post-transcriptional level in the biological function of various cancers, including breast cancer. In our study, miR-346 mimic, inhibitor, negative control or si-SRCIN1 were transfected into MCF-7 and MCF-7/Doc cells, respectively. Quantitative real time PCR (qRT-PCR) was used to measure miR-346...
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,...
Metastasis is the leading cause of death among breast cancer (BCa) patients and triple negative breast cancer (TNBC) as one of BCa subtypes exhibits the worst survival rate due to its highly aggressive and metastatic behavior. A growing body of research has shown that the dynamic expression of microRNAs (miRNAs) was intimately associated with tumor invasion and metastasis. Recent studies have demonstrated...
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)...
SNaPshot minisequencing is a rapid and robust methodology based on a single base extension with a labeled ddNTP. The present study detected 15 selected SNPs in the mitochondrial DNA (mtDNA) control and coding regions by minisequencing methodology using SNaPshot for forensic purpose. The samples were collected from 99 unrelated individuals of the Yi ethnic minority group in Yunnan Province. We have...
The n−3 fatty acid desaturase gene fat1 codes for the n−3 desaturase enzyme, which can convert n−6 polyunsaturated fatty acids (PUFAs) to n−3 PUFAs. The n−3 PUFAs are essential components required for normal cellular function and have preventive and therapeutic effects on many diseases. Goat is an important domestic animal for human consumption of meat and milk. To elevate the concentrations of n−3...
In the present study, we investigated the genetic polymorphisms of 20 novel STR loci and one previously studied locus in the Xibe ethnic group from China, as well as its genetic relationships with neighboring populations. Totally 226 unrelated healthy Xibe individuals were involved in the study. At least 5 alleles were observed for each locus, with the minimum and maximum allelic frequencies of 0...
This study aims to compare the effects of carvedilol and metoprolol in alleviating viral myocarditis (VMC) induced by coxsackievirus B3 (CVB3) in mice.A total of 116 Balb/c mice were included in this study. Ninety-six mice were inoculated intraperitoneally with CVB3 to induce VMC. The CVB3 inoculated mice were evenly divided into myocarditis group (n=32), carvedilol group (n=32) and metoprolol group...
Prohibitin (PHB) is an evolutionarily conserved multifunctional protein with ubiquitous expression. However, its molecular roles are largely unknown.To better understand the function of prohibitin protein in silkworm (BmPHB), its coding sequence was isolated from a cDNA library of silkworm pupae. An His-tagged BmPHB fusion protein was expressed in Escherichia coli Rosetta (DE3) and purified with affinity...
