Melanoma is the deadliest cutaneous neoplasm. To prevent metastasis, early diagnosis and surgical treatment is vital. Long non-coding RNAs (lncRNAs) may serve as biomarkers and therapeutic targets in tumors. We investigated the molecular mechanisms of lncRNA KCNQ1OT1 in melanoma. Real time PCR demonstrated that KCNQ1OT1 expression is up-regulated in melanoma tissues and cells. KCNQ1OT1 promoted cell proliferation and metastasis in melanoma. By directly bindin to miR-153, KCNQ1OT1 acted as a competing endogenous RNA (ceRNA) to de-repress MET expression...

New applications of DNA and RNA sequencing are expanding the field of biodiversity discovery and ecological monitoring, yet questions remain regarding precision and efficiency. Due to primer bias, the ability of metabarcoding to accurately depict biomass of different taxa from bulk communities remains unclear, while PCR-free whole mitochondrial genome (mitogenome) sequencing may provide a more reliable alternative. Here we used a set of documented mock communities comprising 13 species of freshwater macroinvertebrates of estimated individual biomass, to compare the detection efficiency of COI metabarcoding (3 different amplicons) and shotgun mitogenome sequencing...

Bone is one of the most common sites of metastasis in patients with advanced breast cancer; however, the mechanisms of bone metastasis remain to be fully elucidated. Animal models are essential research tools for investigating the mechanisms of diseases and drug actions. To date, there have only been a few reports in which C57BL/6 mice were used for the study of bone metastases of breast cancer. In the current study, we found that intracardiac inoculation of C57BL/6 mouse-derived parental E0771 breast cancer cells (E0771/Pa) frequently lead to bone metastases in C57BL/6 mice within 2 weeks...

Tacrolimus (FK506), an effective immunosuppressant, is widely used in the treatment of autoimmune diseases. In this study, we identified that BulZ, a Streptomyces antibiotic regulatory protein (SARP) family regulator, acted as a positive regulator for spore differentiation and tacrolimus production. A knockout of bulZ resulted in a 47.5% decrease of tacrolimus production and a delay of spore differentiation. Using quantitative real-time PCR (qRT-PCR) analysis and electrophoretic mobility shift assays (EMSAs), it was found that BulZ directly activated the transcriptions of bulZ and bulS2, a putative γ-butyrolactone (GBL) synthetase, and bulS2 was shown to play a positive role in tacrolimus biosynthesis...
