miR-22 Suppresses EMT by Mediating Metabolic Reprogramming in Colorectal Cancer through Targeting MYC-Associated Factor X.

Colorectal cancer (CRC) is one of the most frequent gastrointestinal cancers. MicroRNAs (miRNAs) have been proved to be unusually expressed in CRC progression and thus alter multiple pathological processes in CRC cells. However, the specific roles and mechanisms of miR-22 in CRC have not been clearly reported.

Knockdown of miR-92a suppresses the stemness of colorectal cancer cells via mediating SOCS3.

CRC, cancer cell; CSCs, cancer stem cells; SOCS3, suppressor of cytokine signaling 3.

Zinc finger protein 384 enhances colorectal cancer metastasis by upregulating MMP2.

Zinc finger proteins (ZNFs) serve key roles in tumor formation and progression; however, the functions and underlying mechanisms of dysregulated ZNF384 in colorectal cancer (CRC) are yet to be fully elucidated. Therefore, the present study initially aimed to investigate the expression levels of ZNF384 in CRC samples. Moreover, lentiviral ZNF384 overexpression and ZNF384 knockdown models were established in CRC cells.

MicroRNA-23b-3p targets non-SMC condensing I complex subunit G to promote proliferation and inhibit apoptosis of colorectal cancer cells via regulation of the PI3K/AKT signaling pathway.

Colorectal cancer (CRC) is one of the most common types of malignancy worldwide and has a poor prognosis. Non-SMC condensing I complex subunit G (NCAPG) has been reported to be upregulated in numerous types of malignant tumor. However, to the best of our knowledge, its clinicopathological and biological significance in CRC remain to be elucidated.

Glutamate receptor, ionotropic, N‑methyl D‑aspartate‑associated protein 1 promotes colorectal cancer cell proliferation and metastasis, and is negatively regulated by miR‑296‑3p.

N‑methyl D‑aspartate receptors (NMDARs) are closely associated with the development, growth and metastasis of cancer. Glutamate receptor, ionotropic, N‑methyl D‑aspartate‑associated protein 1 (GRINA) is a member of the of the NMDAR family, and its aberrant expression is associated with gastric cancer. However, the role of GRINA in colorectal cancer (CRC) is not completely understood.

Cytochrome C Oxidase Assembly Factor 1 Homolog Predicts Poor Prognosis and Promotes Cell Proliferation in Colorectal Cancer by Regulating PI3K/AKT Signaling.

Purpose: Colorectal cancer (CRC) is one of the most common malignancies in the world. The prognosis of advanced CRC is still poor. The purpose of this study was to identify a gene expression profile associated with CRC that may contribute to the early diagnosis of CRC and improve patient prognosis.

MiR-92a promotes stem cell-like properties by activating Wnt/β-catenin signaling in colorectal cancer.

We previously reported the oncogenic function of miR-92a in colorectal cancer. This study identified that miR-92a was upregulated in chemoresistant colorectal cancer cells and tissues. Ectopic expression of miR-92a conferred resistance to 5-fluorouracil-induced apoptosis , while antagomiR-92a significantly enhanced chemosensitivity .

MicroRNA-22 suppresses the growth, migration and invasion of colorectal cancer cells through a Sp1 negative feedback loop.

MicroRNAs have recently emerged as regulators of many biological processes including cell proliferation, development and differentiation. This study identified that miR-22 was statistically decreased in colorectal cancer clinical specimens and highly metastatic cell lines. Moreover, low miR-22 expression was associated with tumor metastasis, advanced clinical stage and relapse.

Plasma miR-200c and miR-18a as potential biomarkers for the detection of colorectal carcinoma.

It has been demonstrated that there are abundant stable microRNAs (miRNAs) in plasma/serum, which can be detected and are potentially disease-specific. The aim of this study was to investigate whether plasma miR-200c and miR-18a can be used as biomarkers for the detection of colorectal carcinoma (CRC). This study was divided into three parts: i) confirmation of higher miR-200c and miR-18a levels in primary CRC tissues compared to normal colorectal tissues; ii) evaluation of plasma miR-200c and miR-18a expression by comparing 78 patients with 86 healthy volunteers and iii) comparison of miR-200c and miR-18a levels in paired pre-and post-operative plasma in cancer patients who underwent curative CRC resection.

Laparoscopic rectal resection versus open rectal resection with minilaparotomy for invasive rectal cancer.

Background: The minilaparotomy approach is technically feasible for the resection of rectal cancer in selected patients with rapid postoperative recovery and small incision. The study aimed to compare the clinical and oncological outcomes of minilaparotomy and laparoscopic approaches in patients with rectal cancer.

Methods: The 122 included patients with rectal cancer were assigned to either minilaparotomy group (n=65) or laparoscopic group (n=57) which ran from January 2005 to January 2008.

MicroRNA-92a functions as an oncogene in colorectal cancer by targeting PTEN.

Background: Our previous studies show that microRNA-92a (miR-92a) is overexpressed in colorectal cancer (CRC) and is thought to be correlated with the development of the cancer. However, its biological role in CRC remains poorly understood.

Aims: The aim of the study was to determine the role of miR-92a and to elucidate its regulatory mechanism in CRC.

[Laparoscopic versus open intersphincteric resection for low rectal cancer: a clinical comparative study].

Objective: To compare the clinical and oncological outcomes between laparoscopic and open intersphincteric resection in patients with low rectal cancer.

Methods: From January 2007 to January 2010, patients with low rectal cancer treated by laparoscopic or open intersphincteric resection were included in a retrospective comparative study. Patients were classified into laparoscopy group (n=27) and open group (n=41).

Upregulation of microRNA-155 promotes the migration and invasion of colorectal cancer cells through the regulation of claudin-1 expression.

Human microRNA-155 (miR-155) has been demonstrated to regulate a variety of cellular functions, including epithelial-to-mesenchymal transition (EMT) by targeting multiple messenger RNAs (mRNAs). However, its role in colorectal cancer (CRC) remains unelucidated. Therefore, the aim of the present study was to investigate the effects of miR-155 on CRC cells.

High expression of ZEB1 correlates with liver metastasis and poor prognosis in colorectal cancer.

Zinc finger E-box binding homeobox 1 (ZEB1) has been shown to promote invasion and metastasis in several types of human cancer and to have a prognostic role in certain cancers. However, the clinical significance of ZEB1 in colorectal cancer (CRC) has not been sufficiently investigated. This study aimed to address this issue.

Overexpression of miR-92a correlates with tumor metastasis and poor prognosis in patients with colorectal cancer.

Objectives: MicroRNAs regulate gene expression at the post-transcriptional level and play important roles in cancer development, progression, and metastasis. The aim of this study was to investigate the expression of miR-92a in colorectal cancer and the normal adjacent mucosa and its potential relevance to clinicopathological characteristics and patient survival.

Methods: Surgical specimens of cancer tissue and adjacent normal mucosa were obtained from 82 patients with colorectal carcinomas.

Clinical significance of miR-22 expression in patients with colorectal cancer.

MicroRNAs (miRNAs) are non-coding RNAs that have been shown to be aberrantly expressed in several tumor types. Of these miRNAs, miR-22 as tumor suppressor has been shown to play a crucial role in human carcinogenesis. However, its association with the clinicopathological features of colorectal cancer has yet to be addressed.
