Types 1-4 of fibroblast growth factor receptors (FGFR) are all expressed in various cancers. Because of its prominent role in carcinogenesis and cancer progression, FGFR-2, is being considered as a novel target in cancer treatment. Owing to the alternative splicing of its extracellular domain, FGFR-2 exists in two variants: IIIb and IIIc. FGFR-2 IIIb is mainly expressed in normal epithelial cells, as well as in oral mucosal, esophageal, gastric, colorectal, pancreatic, pulmonary, breast, endometrial, cervical, and prostate cancers...

The understanding of molecular mechanisms that are involved in the development and the progression of gastric cancer (GC) are of importance for the diagnosis and treatment. The calpain system, which contains the calpains and the endogenous inhibitor, has been suggested as an important factor in the tumorigenesis and migration of colorectal adenocarcinoma, breast and ovarian cancer, and as a prognostic marker for GC. However, the expression level of calpain system proteins in GC and normal-appearing peritumoral gastric mucosa remain unknown...

The CASP8 -652 6N insertion/deletion (I/D) polymorphism reduces expression of caspase 8. We conducted a meta-analysis to clarify the relationship between this polymorphism and cancer risk. Eligible articles were retrieved from PubMed, EMBASE, CNKI, and WANFANG databases through February 2017. A total of 33 articles with 49 studies, including 33,494 cases and 36,397 controls, were analyzed. We found that the CASP8 -652 6N ins/del polymorphism was associated with decreased overall cancer risk in five genetic models [DD vs...

We have previously demonstrated the ability of I-Trp to disrupt the protein-protein interaction of β-tubulin with chaperonin-containing TCP-1β (CCT-β). This caused more severe apoptosis in multidrug-resistant MES-SA/Dx5, compared to MES-SA, due to its higher CCT-β overexpression. In this study, we screened a panel of cancer cell lines, finding CCT-β overexpression in the triple-negative breast cancer cell line MDA-MB-231, colorectal cancer cell lines Colo205 and HCT116, and a gastric cancer cell line MKN-45...

Long noncoding RNAs (lncRNAs) are involved in vital life processes of gene expression, epigenetic regulation and X-chromosome inactivation. lncRNAs are also closely associated with tumor initiation and progression. Moreover, lncRNAs may enter human circulation system in the form of microvesicle or exosome, or in combination with RNA binding protein. Interestingly, the circulating lncRNAs are widely existed in body fluids, such as blood and urine. We review the origin of circulating lncRNAs, and the detection methods as potential biomarkers...

In a retrospective study performed in California, U.S.A., ca. 3% of patients with gastric intestinal metaplasia (GIM) developed gastric cancer (GC) within a median time period of 4.6 years after diagnosis of GIM. This observation stresses the importance of targeted surveillance even in regions with a low GC prevalence. Patients with alcoholic liver disease as well as survivors of colorectal and lobular breast cancer were found to be at increased risk of secondary GC. A population-based Chinese study confirmed "serologic biopsy" as a useful screening tool for stratifying the individual risk of developing GC...

Yu-Qian Mao, Walid A Houry
Pontin (RUVBL1, TIP49, TIP49a, Rvb1) and Reptin (RUVBL2, TIP48, TIP49b, Rvb2) are highly conserved ATPases of the AAA+ (ATPases Associated with various cellular Activities) superfamily and are involved in various cellular processes that are important for oncogenesis. First identified as being upregulated in hepatocellular carcinoma and colorectal cancer, their overexpression has since been shown in multiple cancer types such as breast, lung, gastric, esophageal, pancreatic, kidney, bladder as well as lymphatic, and leukemic cancers...

FGFR2 is recurrently amplified in 5% of gastric cancers and 1-4% of breast cancers; however, this molecular alteration has never been reported in a primary colorectal cancer specimen. Preclinical studies indicate that several FGFR tyrosine-kinase inhibitors (TKI), such as AZD4547, have in vitro activity against the FGFR2-amplified colorectal cell line, NCI-H716. The efficacy of these inhibitors is currently under investigation in clinical trials for breast and gastric cancer. Thus, better characterizing colorectal tumors for FGFR2 amplification could identify a subset of patients who may benefit from FGFR TKI therapies...

Heat shock proteins (HSPs) constitute a group of proteins that play crucial role in process of proteins folding. HSPs are also known to modulate number of key apoptotic factors. High expression of these proteins is reported in array of cancers, such as breast, prostate, colorectal, lung, ovarian, gastric, oral and esophageal cancer. Ample amount of investigations carried out on variety of cancers suggests HSPs as a promising hallmark in cancers. Their expression profile in several tumors elucidates that they help in proliferation, invasion, metastasis and death of cancerous cells...

Osteopontin (OPN), a multifunctional protein, has emerged as a potentially valuable biomarker for diagnosing and treating cancers. Recent research focuses on its involvement in tumor biology including the cell proliferation, survival, angiogenesis, invasion, and metastasis. Understanding the molecular mechanisms and pharmacological effects of OPN in cancer development could lead to new targets for improving cancer diagnosis and treatment. This review explains how the structurally conserved domains of OPN are associated with OPN signaling mediators and CD44, and how the conserved OPN domains determine biological functions...

Suppressor of cancer cell invasion (SCAI) has been originally characterized as a tumor suppressor inhibiting metastasis in different human cancer cells, and it has been suggested that SCAI expression declines in tumors. The expression patterns and role of SCAI during physiological and pathophysiological processes is still poorly understood. Earlier we demonstrated that SCAI is regulating the epithelial-mesenchymal transition of proximal tubular epithelial cells, it is downregulated during renal fibrosis and it is overexpressed in Wilms' tumors...

Soon after microRNAs entered the stage as novel regulators of gene expression, they were found to regulate -and to be regulated by- the development, progression and aggressiveness of virtually all human types of cancer. Therefore, miRNAs in general harbor a huge potential as diagnostic and prognostic markers as well as potential therapeutic targets in cancer.The miR-17-92 cluster was found to be overexpressed in many human cancers and to promote unrestrained cell growth, and has therefore been termed onco-miR-1...

Gastrointestinal (GIT) malignancies are a substantial health concern. Most patients present to the clinics with advanced and un-resectable diseases, so it remains difficult to cure with the existing chemotherapeutic regimes. It is therefore extremely important to devise novel therapeutic targets in these neoplasms in order to improve patient's survival. One such target is human epidermal growth factor, also known as Her-2. Although Her-2 expression and the use of a-Her-2 medications in breast cancers is well established, but its expression and potential use as a therapeutic target in gastrointestinal malignancies remains controversial and heavily debated...

Canonical WNT signaling through Frizzled and LRP5/6 receptors is transduced to the WNT/β-catenin and WNT/stabilization of proteins (STOP) signaling cascades to regulate cell fate and proliferation, whereas non-canonical WNT signaling through Frizzled or ROR receptors is transduced to the WNT/planar cell polarity (PCP), WNT/G protein-coupled receptor (GPCR) and WNT/receptor tyrosine kinase (RTK) signaling cascades to regulate cytoskeletal dynamics and directional cell movement. WNT/β-catenin signaling cascade crosstalks with RTK/SRK and GPCR-cAMP-PKA signaling cascades to regulate β-catenin phosphorylation and β-catenin-dependent transcription...

The transcription factor, zinc-finger protein 545 (ZNF545), that belongs to the Kruppel-associated box zinc-finger protein (KRAB-ZFP) family, acts as a tumor suppressor and is inactivated by promoter methylation in cancers such as nasopharyngeal carcinoma, breast cancer, and gastric cancer, but its role in colorectal cancer (CRC) is unknown. The purpose of this study was to characterize the ZNF545 expression, methylation status, biological function, and related molecular mechanisms in CRC. The results showed that ZNF545 was expressed in adult normal colorectal tissues, but downregulated or silenced in CRC cell lines, and this mechanism was reversed by demethylation treatment with 5-aza-2'-deoxycytidine and trichostatin A...

Recent studies have found that cancer-testis (CT) genes, which are expressed predominantly in germ and cancer cells, may be candidate cancer drivers. Because of their crucial roles, genetic variants in these genes may contribute to the development of cancer. Here, we systematically evaluated associations of common variants in CT genes and their promoters for the risk of lung cancer in our initial GWAS (2331 cases and 3077 controls), followed by in silico replication using additional 10,512 lung cancer cases and 9562 controls...
