Crickets whose paired connectives between the metathoracic ganglion and abdominal ganglia were cut initiated walking, although the gait was not a coordinated tripod pattern, whereas the crickets exhibited a tripod gait when one side of the connectives was intact. These results suggest that the brain plays an inhibitory role in initiating leg movements and that both the descending signals from the head ganglia and the ascending signals from the abdominal nervous system are important in initiating and coordinating insect walking gait patterns.Molecular docking is central to rational drug design. Current docking techniques suffer, however, from limitations in protein flexibility and solvation models and by the use of simplified scoring functions. All-atom molecular dynamics simulations, on the other hand, feature a realistic representation of protein flexibility and solvent, but require knowledge of the binding site. Recently we showed that coarse-grained molecular dynamics simulations, based on the most recent version of the Martini force field, can be used to predict protein/ligand binding sites and pathways, without requiring any a priori information, and offer a level of accuracy approaching all-atom simulations. Given the excellent computational efficiency of Martini, this opens the way to high-throughput drug screening based on dynamic docking pipelines. In this opinion article, we sketch the roadmap to achieve this goal.LncRNAs are defined as non-coding RNAs that are longer than 200 nucleotides in length. The previous studys has shown that lncRNAs played important roles in the regulation of gene expression and were essential in mammalian development and disease processes. Inspired by the observation that lncRNAs are aberrantly expressed in tumors, we extracted RNA from Bladder urothelial carcinoma and matched histologically normal urothelium from each patient and bladder carcinoma cell lines. DNA-PK inhibitor Then, we reversed transcribed them into cDNA.Last, we investigated the expression patterns of ERIC by the fluorescence quantitative PCR in bladder cancer tissues and cell lines. CRISPR-dCas9-VPR targeting ERIC plasmid was transfected into T24 and 5637 cells, and cells were classified into two groups negative control (NC) and ERIC overexpression group. MTT assay, transwell assay, and flow cytometry were performed to examine changes in cell proliferation, invasiveness, and apoptosis. We found that the expression of ERIC was down-regulated in bladder urothelial carcinoma compared to matched histologically normal urotheliam. The differences of the expression of this gene were large in the bladder cancer lines. Compared with the negative control group, the ERIC overexpression group showed significantly decreased cell proliferation rate (t = 7.583, p = 0.002; t = 3.283, p = 0.03) and invasiveness (t = 11.538, p less then 0.001; t = 8.205, p = 0.01); and increased apoptotic rate (t = -34.083, p less then 0.001; t = -14.316, p less then 0.001). Our study lays a foundation for further study of its pathogenic mechanism in bladder cancer.The average age of the world's elderly population is steadily increasing. This unprecedented rise in the aged world population will increase the prevalence of age-related disorders such as cardiovascular disease (CVD) and neurodegeneration. In recent years, there has been an increased interest in the potential interplay between CVDs and neurodegenerative syndromes, as several vascular risk factors have been associated with Alzheimer's disease (AD). Along these lines, arterial stiffness is an independent risk factor for both CVD and AD. In this review, we discuss several inflammaging-related disease mechanisms including acute tissue-specific inflammation, nitro-oxidative stress, impaired autophagy, and insulin resistance which may contribute to the proposed synergism between arterial stiffness and AD.CRISPR-CasRx technology provides a new and powerful method for studying cellular RNA in human cancer. Herein, the pattern of expression of long noncoding RNA 00341 (LINC00341) as well as its biological function in bladder cancer were studied using CRISPR-CasRx. qRT-PCR was employed to quantify the levels of expression of LINC00341 in tumor tissues along with the matched non-tumor tissues. sgRNA targeting LINC00341 or the sgRNA negative control were transiently transfected into the T24 as well as 5,637 human bladder cancer cell lines. CCK-8, ELISA as well as wound healing methods were employed to explore cell proliferation, apoptosis and migration, respectively. The tumorigenicity experiment in nude mice also performed to detect cell proliferation. The expression of p21, Bax as well as E-cadherin were assayed using western blot. The results demonstrated that LINC00341 was overexpressed in bladder cancer in contrast with the healthy tissues. The LINC00341 expression level in high-grade tumors was higher in contrast with that in low-grade tumors. The expression of linc00341 was higher relative to that of non-invasive tumors. In T24 as well as 5637-cell lines harboring LINC00341-sgRNA, inhibition of cell proliferation (in vitro and in vivo), elevated apoptosis rate and diminished migration ability. Moreover, silencing LINC00341 upregulated the expressions of p21, Bax as well as E-cadherin. Knockout of these genes could eliminate the phenotypic changes caused by sgRNA targeting LINC00341. Our data demonstrate that LINC00341 has a carcinogenic role in human bladder cancer.Glycolysis inhibitors are promising therapeutic drugs for tumor treatment, which target the uniquely elevated glucose metabolism of cancer cells. Butyrate is a critical product of beneficial microbes in the colon, which exerts extraordinary anti-cancer activities. In particular, butyrate shows biased inhibitory effects on the cell growth of cancerous colonocytes, whereas it is the major energy source for normal colonocytes. Besides its roles as the histone deacetylases (HDACs) inhibitor and the ligand for G-protein coupled receptor (GPR) 109a, the influence of butyrate on the glucose metabolism of cancerous colonocytes and the underlying molecular mechanism are not fully understood. Here, we show that butyrate markedly inhibited glucose transport and glycolysis of colorectal cancer cells, through reducing the abundance of membrane GLUT1 and cytoplasmic G6PD, which was regulated by the GPR109a-AKT signaling pathway. Moreover, butyrate significantly promoted the chemotherapeutical efficacy of 5-fluorouracil (5-FU) on cancerous colonocytes, with exacerbated impairment of DNA synthesis efficiency.
