Scaffold proteins play pivotal roles in the regulation of signaling pathways, integrating external and internal stimuli to various cellular outputs. We report the pattern of cellular and subcellular expression of scaffoldins angiomotin-like 2 (AmotL2), FK506 binding protein 5 (FKBP51) and IQ motif containing GTPase-activating protein 1 (IQGAP1) in colorectal cancer (CRC) and metastases in liver resected after oxaliplatin-based chemotherapy (CT). Positive immunostaining for the three scaffoldins was found in most cells in healthy colon, tumor, healthy liver and metastasized liver...

Yongchen Guo, Yonghua Bao, Wancai Yang
Colorectal cancer is one of the most common malignancies and is the second-leading cause of cancer-related death world-wide, which is linked to genetic mutations, epigenetic alterations, and oncogenic signaling activation. MicroRNAs, one of the categories of epigenetics, have been demonstrated significant roles in carcinogenesis and progression through regulating of oncogenic signaling pathways, stem cells, epithelial-mesenchymal transition, and metastasis. This review summarizes the roles of microRNAs in the regulating of Wnt, Ras, TGF-β, and inflammatory signaling pathways, stemness, and epithelial-mesenchymal transition, for carcinogenesis and metastasis in colorectal cancer...

Purpose In March 2007, a US Food and Drug Administration boxed warning was issued for erythropoietin-stimulating agents (ESAs) regarding serious adverse events, such as venous thromboembolism (VTE). We evaluated the US Food and Drug Administration's boxed warning of ESAs used to treat chemotherapy-induced anemia because evidence on the effectiveness of boxed warnings remains inconclusive. Patients and Methods Using 2004 to 2009 SEER-Medicare data, we exploited a natural experiment to examine the effects of ESA boxed warnings on utilization and risk of VTE...

Accumulating evidence shows that mircroRNAs (miRNAs) play a crucial role in the development of colorectal cancer. In our previous study, FAM172A was demonstrated to be a novel tumor suppressor gene in CRC. Therefore, the aim of the present study was to identify whether the miR‑27a could be a diagnostic and prognostic marker and the regulatory relationships between miR‑27a and FAM172A. We demonstrated high levels of miR‑27a expression in tissues of patients with CRC as well as in CRC cell lines. There was a positive correlation between the levels of miR‑27a and the poor overall survival of patients with CRC...

The aberrant expression of miR-30d has been reported in several types of human malignancies. However, its biological function in colorectal cancer (CRC) remains largely unknown. In this study, we identified that miR‑30d was significantly downregulated in CRC tissues compared to that observed in normal controls as detected by RT‑qPCR analysis. Downregulation of miR‑30d was significantly associated with aggressive clinicopathological parameters including tumor differentiation, invasive depth, TNM stage, lymph node metastasis, distant metastasis, and poor prognosis...

Malformations of the rectum and urinary tract frequently coexist, and the prevalence of urogenital defects in patients with a rectal defect ranges from 20 to 54%. In most patients, anorectal malformations are diagnosed and treated surgically in early childhood. In this report, we present a case of a 52-year-old male with a history of urological operations in infancy due to a congenital urethral malformation and multiple recurrent episodes of perineal abscesses with urinary retention. Anorectal endosonography and magnetic resonance imaging revealed the presence of a large cystic lesion adjacent to the rectal wall which became smaller at the level of the puborectalis...

Human colorectal cancer stem cells (CSCs) are tumour initiating cells that can self-renew and are highly tumorigenic and chemoresistant. While genetic mutations associated with human colorectal cancer development are well-known, little is known about how and whether epigenetic factors specifically contribute to the functional properties of human colorectal CSCs. Here we report that the KDM3 family of histone demethylases plays an important role in tumorigenic potential and survival of human colorectal CSCs by epigenetically activating Wnt target gene transcription...

MicroRNA-145 (miR-145), as a tumor-suppressive miRNA, has been demonstrated down-regulated in colorectal cancer (CRC) cells, and could inhibit CRC cells growth. However, the molecular pathway in which miR-145 modulates CRC malignant transformation has not been fully revealed. Here, we reported an intense correlation between the expressions of PAK4 and miR-145 in human CRC cell lines. Transwell assay verified overexpression of miR-145, as well as knockdown of PAK4, significantly suppressed cell migration and invasion ability...

BACKGROUND: Abdominal pain is one of the major symptoms of inflammatory Bowel Disease (IBD). The inflammatory mediators released by colon inflammation are known to sensitize the afferent neurons, which is one of the contributors to abdominal pain. However, not all IBD patients have abdominal pain, and some patients report abdominal pain during remission, suggesting contributions of other pathological factors to abdominal pain in IBD. Epidemiological studies found early-life gastrointestinal infections a risk factor for IBD symptoms and adult-life gastrointestinal infections may trigger the onset of IBD...
