Colorectal cancer (CRC) is reported to be the third and fourth, most diagnosed and cause of cancer associated deaths respectively. In 2012 for instance, about 1.4 million new cases were reported, and approximately 700,000 deaths recorded. Survival from CRC is dependent on the stage at which it is diagnosed coupled with appropriate surgical and medical intervention. Cisatracurium is widely used for skeletal muscle relaxation during abdominal surgeries, including bowel and colon surgeries. Recent studies reported that cisatracurium inhibits progression of human cancer cells, however, the mechanisms leading to the inhibition are yet to be completely understood...

Peritoneal metastasis is the second leading cause of death of colorectal cancer patients. Cytoreductive surgery (CRS) combined with hyperthermia intraperitoneal chemotherapy (HIPEC) is the primary method to treat peritoneal metastasis of colorectal cancer, though there remain some controversies. We reviewed current studies of colorectal peritoneal carcinomatosis (PC) and CRS+ HIPEC, and discussed some issues with regard to the scoring system for peritoneal metastasis, selection criteria for CRS+ HIPEC treatment, and the new drug application for colorectal PC...

Oral cancers constitute approximately 2% of all cancers, with the most common histological type being oral squamous cell carcinoma (OSCC), representing 90% of oral cancers. Although diagnostic technologies and therapeutic techniques have progressed, the survival rate of patients with OSCC is still 60%, whereas the incidence rate has increased. Podocalyxin (PODXL) is a highly glycosylated type I transmembrane protein that is detected in normal tissues such as heart, breast, and pancreas as well as in many cancers, including lung, renal, breast, colorectal, and oral cancers...

BACKGROUND: Colorectal cancer (CRC) remains a leading cause of cancer-related morbidity and mortality in both sexes globally. This is not unconnected with the heterogeneity and plasticity of CRC stem cells (CRC-SCs) which stealthily exploit the niche-related and (epi)genetic factors to facilitate metastasis, chemoresistance, tumor recurrence, and disease progression. Despite the accumulating evidence of the role of dysregulated microRNAs in malignancies, the therapeutic efficacy of pharmacological-targeting of CRC-SC-associated microRNAs is relatively under-explored...

OBJECTIVES: Colorectal cancer (CRC), one of the most aggressive gastrointestinal malignancies, is a frequently diagnosed life-threatening cancer worldwide. Most CRC patients have poor prognosis mainly because of frequent metastasis and recurrence. Thus, it is crucial to find out some new biomarkers and to show deeper insights into the mechanisms of CRC. MLLT10, Myeloid/lymphoid or mixed-lineage leukemia translocated to 10, also known as AF10, a recurrent MLL partner. In this study, we found that MLLT10 promotes CRC tumor invasion and metastasis both in vitro and in vivo...

Long non-coding RNAs (lncRNAs) regulate diverse cellular processes, and their anomalous expression exert an essential role in the progression of many kinds of cancers, including colorectal carcinoma (CRC). The objective of this study was to investigate the role of lncRNA kcna3 and its underlying mechanism in CRC progression. The expression of lncRNA kcna3 in human CRC tissues and the adjacent non-tumor tissues was evaluated by RT-PCR. The correlations between lncRNA kcna3 expression levels and the overall survival (OS), as well as the clinicopathological features of CRC patients were analyzed...

BACKGROUND & AIMS: Combined inactivation of the microRNA 34a gene (MIR34A, by methylation) and the TP53 gene (by mutation or deletion) is observed in 50% of colorectal tumors that progress to distant metastases. We studied mice with intestinal disruption of Mir34a and Tp53 to investigate mechanisms of colorectal carcinogenesis and identify strategies to block these processes. METHODS: Mice with disruption of Mir34a and/or Tp53 specifically in intestinal epithelial cells (Mir34aΔIEC mice, Tp53ΔIEC mice, and Mir34aΔIEC /Tp53ΔIEC mice) and controls (Mir34aFl/Fl /Tp53Fl/Fl ) were given azoxymethane to induce colorectal carcinogenesis...

At the time of diagnosis, 20% of patients with colorectal cancer (CRC) present with metastasis. Among individuals with primary lesions, 50% of them will develop distant tumors with time. Therefore, early diagnosis and prediction of aggressiveness is crucial for therapy design and disease prognosis. Tumoral cells must undergo significant changes in energy metabolism to meet increased structural and energetic demands for cell proliferation, and metabolic alterations are considered to be a hallmark of cancer. Here, we present ABCA1, a regulator of cholesterol transport, as a new marker for invasion and colorectal cancer survival...

Wnt/β-catenin signaling plays a critical role during development of both normal and malignant colorectal cancer (CRC) tissues. Phosphorylation of β-catenin protein alters its trafficking and function. Such conventional allosteric regulation usually involves a highly specialized set of molecular interactions, which may specifically turn on a particular cell phenotype. This study identifies a novel transcription modulator with an FLYWCH/Zn-finger DNA-binding domain, called "FLYWCH1". Using a modified yeast-2-hybrid based Ras-Recruitment system, it is demonstrated that FLYWCH1 directly binds to unphosphorylated (nuclear) β-catenin efficiently suppressing the transcriptional activity of Wnt/β-catenin signaling that cannot be rescued by TCF4...

BACKGROUND: Curcumin, a well-studied component in turmeric, exhibits potent antitumor effects in colorectal cancer. Previous studies showed that turmerones raised the accumulation of curcumin inside colonic cells, and curcumin present in turmeric ethanolic extract had enhanced anti-tumor activities in mice. Metastasis accounts for more than 90% colorectal cancer deaths. However, the anti-metastatic effect of turmeric extract on colorectal cancer is still unknown. METHODS: In the present study, colony formation, scratch, transwell and Western blot were used to assess colony formation, motility, migration and underlying mechanisms in vitro, respectively...

Advanced colorectal cancer (CRC) is one of the deadliest cancers, and the 5-year survival rate of patients with metastasis is extremely low. The epithelial-mesenchymal transition (EMT) is considered essential for metastatic CRC, but the fundamental molecular basis underlying this effect remains unknown. Here, we identified that O-GlcNAcylation, a unique posttranslational modification (PTM) involved in cancer metabolic reprogramming, increased the metastatic capability of CRC. The levels of O-GlcNAcylation were increased in the metastatic CRC tissues and cell lines, which likely promoted the EMT by enhancing EZH2 protein stability and function...

Emerging evidence has proven that long noncoding RNAs (lncRNAs) play important roles in human colorectal cancer (CRC) biology, although few lncRNAs have been characterized in CRC. Therefore, the functional significance of lncRNAs in the malignant progression of CRC still needs to be further explored. In this study, through analyzing TCGA RNA sequencing data and other publicly available microarray data, we found a novel lncRNA, LINC00460, whose expression was significantly upregulated in CRC tissues compared to adjacent normal tissues...

One of the major causes of death in colorectal cancer (CRC) is invasion and metastasis. Better understanding of the molecular mechanism of CRC invasion and metastasis is essential in developing effective cancer therapies. Cooperative effect of CXCR3 and CXCR4 plays a crucial role in regulating CRC invasion. In present study, we discovered that CRC cells expressing higher levels of CXCR3 and CXCR4 were more invasive. Additionally, CXCR3 formed heteromers with CXCR4 and retained CXCR4 on cell surface. CXCR3 knockdown reduced surface CXCR4 expression and partially inhibited CRC cell invasion...

Melatonin suppresses tumor development. However, the exact relationship between melatonin and cancer stem cells (CSCs) is poorly understood. This study found that melatonin inhibits colon CSCs by regulating the PrPC -Oct4 axis. In specimens from patients with colorectal cancer, the expressions of cellular prion protein (PrPC ) and Oct4 were significantly correlated with metastasis and tumor stages. Co-treatment with 5-fluorouracil (5-FU) and melatonin inhibited the stem cell markers Oct4, Nanog, Sox2, and ALDH1A1 by downregulating PrPC ...

REVIEW

Sessile serrated adenoma/polyps (SSA/Ps) are early precursor lesions in the serrated neoplasia pathway, which results in colorectal carcinomas with BRAF mutations, methylation for DNA repair genes, a CpG island methylator phenotype, and high levels of microsatellite instability. Some of these lesions can rapidly become dysplastic or invasive carcinomas that exhibit high lymphatic invasion and lymph node metastasis potentials. Detecting serrated lesions, including SSA/Ps with and without dysplasia/carcinoma, is critical, but SSA/Ps can be difficult to detect, are inconsistently identified by endoscopists and pathologists, and are often incompletely resected...
