Adrenomedullin (AM) exerts a potent anti-inflammatory effect. Intrarectal or consecutive intravenous administrations of AM reduce pathological manifestations in rodent colitis models. However, in clinical applications, a safer administration route that provides stronger alleviation of patient burden is preferred. We investigated whether subcutaneously administered AM is effective against dextran sulfate sodium (DSS)-induced colitis. C57BL/6J mice were administered 1% DSS in drinking water and received AM at 8, 40 or 80 nmol/kg subcutaneously once a day for 7 consecutive days...

Bone grafting is necessary before dental implant treatment in patients with jaw bone defects. Currently, autologous bone grafting is a major burden on the patient. However, it is impossible to form a sufficient foundation for the implant with a bone-filling agent alone. It is, therefore, necessary to prepare hybrid artificial bone tissue containing osteoblasts and osteoclasts. In this study, mouse MC3T3-E1 pre-osteoblast cells and human embryonic-derived osteoblastic cell line hFOB1.19 were cultured in radial-flow bioreactors (RFB) to form three-dimensional artificial bone filled with porous beads of β-tricalcium phosphate (β-TCP) or hydroxyapatite (HA)-which are clinically used as bone-filling agents-as cell culture carriers...

The prognosis of colorectal cancer (CRC) is still very poor, owing to the high incidence of metastasis. Long noncoding RNA TCF7 (lncTCF7) has been shown to play critical roles in human CRC development and progression, but the molecular mechanisms of lncTCF7 in CRC are still unknown. This study aimed to explore the functions and molecular mechanisms of lncTCF7 on the migration and invasion of CRC cells. Notably, lncTCF7 was highly expressed in CRC cell lines relative to normal colonic epithelial cells. LncTCF7 knockdown significantly inhibited migration and invasion of CRC cells...

Obesity is associated with increased risks of diverse diseases; brown adipose tissue (BAT) can increase energy expenditure and protect against obesity by increasing the decomposition of white adipose tissue (WAT) to enhance the non-coupled oxidative phosphorylation of fatty acid in adipocytes and contributes to weight loss. However, BAT is abundant in only small rodents and newborn humans, but not in adults. PRDM16 is a key factor that induces the differentiation of skeletal muscle precursors to brown adipocytes and simultaneously inhibits myogenic differentiation...

Accumulating evidence has demonstrated that there is critical involvement of miRNAs in the initiation and progression of cancers. Here, we showed that miR-323a-3p was significantly down-regulated in osteosarcoma (OS) tissues and cell lines. Overexpression of miR-323a-3p decreased the cell viability, colon formation and induced the apoptosis of OS cells. Using bioinformatics analysis, lactate dehydrogenase A (LDHA) was predicted as one of the down-steam targets of miR-323a-3p. Highly expressed miR-323a-3p significantly decreased both the mRNA and protein levels of LDHA...

Osteosarcoma is the most common malignant bone neoplasia affecting individuals in the second decade of life. The survival rate has not been improved during the last 25 years, in part because of the lack of specific markers. The microRNAs have been identified as important regulators of gene expression, experimental evidence suggests these molecules as key players in cancer development and progression. To identify miRNAs differentially expressed in serum from patients with osteosarcoma compared to healthy donors in Mexican population...

Human cell lines represent a valuable resource as in vitro experimental models. A hepatoma cell line, HuH-7 (JCRB0403), has been used extensively in various research fields and a number of studies using this line have been published continuously since it was established in 1982. However, an accurate genome profile, which can be served as a reliable reference, has not been available. In this study, we performed M-FISH, SNP microarray and amplicon sequencing to characterize the cell line. Single cell analysis of metaphases revealed a high level of heterogeneity with a mode of 60 chromosomes...

Atrial fibrosis influences atrial fibrillation (AF) development by transforming growth factor beta 1 (TGF-β1)/Smad pathway. Although microRNAs are implicated in the pathogenesis of various diseases, information regarding the functional role of microRNAs in atrial dysfunction is limited. In the present study, we found that microRNA-27b (miR-27b) was the dominant member of miR-27 family expressed in left atrium. Moreover, the expression of miR-27b was significantly reduced after angiotensin II (AngII) infusion...

Because sperm chromatin may play a key role in reproductive success, we verify the associations between sperm chromatin abnormalities, embryo development and the ability to achieve pregnancy. The evaluation of sperm chromatin maturity using aniline blue (AB), chromomycin A3 (CMA3) and toluidine blue (TB) staining were carried out in group of males from infertile couples that underwent ICSI. Low levels of sperm chromatin abnormalities (< 16%) were found in most subjects (> 50%). A higher percentage of TB-positive sperm cells were discovered in the men from couples who achieved ≤ 50% fertilized oocytes compared to men who achieved > 50%...

Bladder cancer has been identified as one of the most malignant cancers with high incidence and mortality. The underlying mechanisms by which regulate the tumorigenesis of bladder cancer deserve further investigation. Here, we found that miR-192-5p was downregulated in human bladder cancer cell lines and tissues. Overexpression of miR-192-5p significantly inhibited the growth of bladder cancer cells, while depletion of miR-192-5p exerted opposite effect. Bioinformatics analysis and molecular mechanism study identified that miR-192-5p targeted the transcription factor Yin Yang 1 (YY1) and decreased the expression level of YY1...
