Aberrant levels of preadipocyte differentiation, triggered by adipocyte hyperplasia and hypertrophy, results in the obesogenic phenotype. Obesity is a risk factor for several metabolic disorders. In this paper, dehydroleucodine inhibited the accumulation of lipid droplets and decreased the elevations of triglycerides, and this inhibitory effect occurred during the early stage of adipogenesis. Thus, not only did dehydroleucodine downregulate the expression of C/EBPα and PPARγ, it also strongly blocked the expression of C/EBPβ, an early stage biomarker of early adipogenesis, in a concentration-dependent manner...

The incidence and mortality rate of bladder cancer have dramatically expanded, so it's urgent to discover new biomarker and therapeutic target for bladder cancer. Recently, lncRNA has been identified as oncogene or tumor suppressor to regulate the tumorigenesis. LncRNA ZFAS1 has been confirmed as oncogene in various tumors. However, the expression, function, and underlying mechanism of ZFAS1 in bladder carcinogenesis have yet to be totally clarified. In the current study, our data demonstrated that ZFAS1 expression was significantly upregulated in bladder cancer tissues and cell lines...

Acute kidney injury (AKI) has a high prevalence in critical care patients. Early detection might prevent patients from developing chronic kidney disease and requirement for renal replacement therapy. If we compare AKI with acute coronary syndrome, in which an increase in cardiac troponin may trigger early diagnosis and therapeutic intervention, we could extrapolate a similar technique in patients with early AKI without changes in urinary frequency or serum creatinine. The objective is to identify biomarker-positive, creatinine-negative patients that would allow therapeutic interventions to be initiated before finding changes in serum creatinine, preventing kidney damage...

The elevated requirement of methionine by cancer cells (methionine dependence) is a general metabolic abnormality in cancer. Methionine-dependent cancer cells are unable to proliferate and arrest in the late S/G2 phase of the cell cycle when methionine is restricted in vitro or in vivo. Cell-cycle arrest in late S/G2 was used as a biomarker of methionine dependence for patient tumors in Gelfoam®  histoculture. Human cancer patient tumors, including tumors of the colon, breast, ovary, prostate, and a melanoma, were observed to be methionine dependent in Gelfoam® histoculture based on cell cycle analysis...

Heregulin‑1β is capable of promoting the nerve regeneration of acellular nerve allografts with skin‑derived precursor differentiated Schwann cell (SC) therapy in peripheral nerve injury. Long non‑coding RNAs (lncRNAs) serve important roles in the regulation of gene transcription and trans-lation in multiple biological processes, but its association with the repair of peripheral nerve injury is unexplored. Therefore, in the present study, the aim was to identify novel indicators for peripheral nerve injury, and to detect whether there is an association between lncRNA expression and the treatment effect of heregulin‑1β on this disorder...

Sulfur mustard is a vesicant chemical warfare agent, which has been used during Iraq-Iran-war. Many veterans and civilians still suffer from long-term complications of sulfur mustard exposure, especially in their lung. Although the lung lesions of these patients are similar to Chronic Obstructive Pulmonary Disease (COPD), there are some differences due to different etiology and clinical care. Less is known on the molecular mechanism of sulfur mustard patients and specific treatment options. microRNAs are master regulators of many biological pathways and proofed to be stable surrogate markers in body fluids...

Esophageal cancer is one of the most common types of malignant tumors located within the digestive system, with >50% of esophageal cancer cases worldwide occurring in China. Recent studies have demonstrated that long non-coding RNAs (lncRNAs) are frequently dysregulated in cancer; however, few lncRNAs have been characterized in esophageal squamous cell carcinoma (ESCC). In the present study, a novel lncRNA, SET-binding factor 2 (SBF2) antisense RNA1 (SBF2-AS1) was exhibited in ESCC. Expression levels of SBF2-AS1 in ESCC and adjacent non-cancerous tissues were detected using the reverse transcription-quantitative polymerase chain reaction...

Bladder cancer is the most common tumor of the urinary tract. Tyrosine 3-monooxygenase/tryptophan 5-monooxygenase activation protein zeta (YWHAZ), a gene encoding the 14-3-3ζ protein, has been observed to be frequently amplified in bladder cancer. However, the role of 14-3-3ζ in various types of cancer is controversial. With reproduction of The Cancer Genome Atlas database, we searched the correlation of YWHAZ expression with survival outcomes of multiple cancers in silico. Our results revealed that only in bladder cancer was there a positive survival trend with YWHAZ overexpression...

Inconsistent results of Sex-determining region Y-box2 (SOX2) expression have been reported in gastric cancer (GC) before. Our recent studies showed that SOX2 was significantly downregulated in GC cells compared with GES-1 at both mRNA and protein level. Transfected with pcDNA3.1-SOX2 resulted in enforced expression of SOX2 at mRNA and protein levels compared with NC group in undifferentiated cell lines including HGC27 and BGC823. MTT assay showed that exogenous expressed SOX2 suppressed cell proliferation. FC analysis revealed that SOX2-overexpressing cells exhibited cell-cycle arrest and apoptosis...

The commonly used antimitotic chemotherapeutic agents such as taxol and vinblastine arrest cell cycle progression by disrupting mitotic spindles, and cause cancer cells to undergo apoptosis through 'mitotic catastrophe'. The molecular mechanisms by which these drugs induce apoptosis and their relevance to clinical efficacy are not known. Facilitated by a new spindle poison diazonamide, we found that apoptosis induced by these agents requires death receptor 3 (DR3). Mitotic arrest by these agents induces lysosome-dependent secretion of the DR3 ligand, TL1A...

Long non-coding RNA (lncRNA) AC026166.2-001 was found to be down-regulated in laryngeal squamous cell carcinoma (LSCC) tissues and metastatic neck lymph nodes. Decreased AC026166.2-001 was associated with poorer prognosis and may act as a novel biomarker for LSCC patients. In this study, AC026166.2-001 was overexpressed by a lentivirus vector and down-regulated by a small interfering RNA (siRNA). The results of real-time cell analysis (RTCA) and a plate colony formation assay showed that AC026166.2-001 inhibited LSCC cell proliferation and the clone-forming capacity...
