Left ventricular hypertrophy (LVH) is a common complication in patients with CKD and an independent risk factor for death. Changes the levels of uremic solutes or Klotho have been reported to be related CKD, whereas relationships between these factors CKD-associated LVH remain unclear. Here, we investigated interaction indoxyl sulfate (IS), typical solute, LVH. In survey 86 negative relationship was found serum IS (r=−0.59, P<0.001). Furthermore, were independently associated (for IS:...

In recent years, natural orifice specimen extraction surgery (NOSES) in the treatment of colorectal cancer has attracted widespread attention. The potential benefits NOSES including reduction postoperative pain and wound complications, less use analgesic, faster recovery bowel function, shorter length hospital stay, better cosmetic psychological effect have been described surgery. Despite significant decrease surgical trauma observed, pitfalls this technique demonstrated. Particularly,...

Abstract Increased basic fibroblast growth factor‐2 ( FGF2 ) and reduced Klotho have both been reported to be closely associated with renal fibrosis. However, the relationship between remains unclear. We demonstrate that induced tubulo‐epithelial plasticity in cultured HK ‐2 cells, accompanied by a reduction expression, whereas recombinant protein could inhibit action of . The effects required extracellular signal‐regulated kinase 1/2 activation, which was suppressed Klotho. Moreover, also...

MicroRNA-93 (miR-93) is involved in several carcinoma progressions. It has been reported that miR-93 acts as a promoter or suppressor different tumors. However, till now, the role of colon cancer unclear. Herein, we have found expression was lower human tissue and colorectal cell lines compared with normal mucosa. Forced cells inhibits invasion, migration, proliferation. Furthermore, may downregulate Wnt/β-catenin pathway, which confirmed by measuring level β-catenin, axin, c-Myc, cyclin-D1...

Apolipoprotein E (ApoE) plays a key role in tumorigenesis and progression, such as cell proliferation, angiogenesis metastasis. ApoE overexpression was associated with aggressive biological behaviors poor prognosis variety of tumor according to previous studies. This study aimed assess the prognostic value explore potential relationship progression colorectal cancer (CRC). We collected expression profiling microarray data from Gene Expression Omnibus (GEO), investigated pattern between...

Ischemic-reperfusion injury (IRI) is a major pathogenic factor in acute kidney (AKI), which directly leads to the hypoxic of renal tubular epithelial cells (RTECs). Although emerging studies suggest repressor element 1–silencing transcription (REST) as master regulator gene repression under hypoxia, its role AKI remains elusive. Here, we found that REST was upregulated patients, mice, and RTECs, positively associated with degree injury, while tubule–specific knockout Rest significantly...

Although the recommended minimal examined lymph node (ELN) number in rectal cancer (RC) is 12, this standard remains controversial because of insufficient evidence. We aimed to refine definition by quantifying relationship between ELN number, stage migration and long-term survival RC.Data from a Chinese multi-institutional registry (2009-2018) Surveillance, Epidemiology, End Results (SEER) database (2008-2017) on stages I-III resected RC were analysed determine count, migration, overall (OS)...

To investigate the role of miR-450b-5p, a newly identified microRNA, located in Xq26 region, development chemoresistance colorectal cancer (CRC), and to explore underlying mechanism by which miR-450b-5p regulates this process. In study, we demonstrated that expression was downregulated recurrent CRC tissues. We found significantly inhibited response 5-fluorouracil (5-FU) treatment HT-29 cells HCT-116 cells. Importantly, overexpression 5-FU-resistant reduced cell viability, but elevated DNA...

p50-associated cyclooxygenase-2 extragenic RNA (PACER) is a recently identified antisense long non-coding (lncRNA) located on the upstream of promoter region (COX-2). Preliminary studies have suggested that PACER involved in regulation COX-2 expression macrophagocyte and osteosarcoma cells. However, role this lncRNA colorectal cancer (CRC) remains elusive. Here, we investigated its effect cell proliferation invasion to explore CRC. Real-time quantitative PCR (RT-qPCR) analysis was used...

Background: Acute kidney injury (AKI) occurs in approximately 7-18% of all hospitalizations, but there are currently no effective drug therapy for preventing AKI or delaying its progression to chronic disease (CKD). Recent studies have shown that Scutellaria baicalensis, a traditional Chinese herb, could attenuate cisplatin-induced AKI, although the mechanism remains elusive. Further, it is unknown whether major active component, Oroxylin A (OA), can alleviate injury. Methods: The...
