Synthetic lethality is a molecular targeted therapy for selective killing of cancer cells. We exploited a lethal interaction between Superoxide dismutase1 inhibition and Bloom syndrome gene product (BLM) defect for the treatment of colorectal cancer (CRC) cells (HCT 116) with lung cancer screen-1 (LCS-1) loaded customized nanocarrier. LCS-1 has poor aqueous solubility. To overcome its limitations, customized nanocarrier (NC), composed of magnetite core coated with three polymeric shells namely, aminocellulose, branched poly(amidoamine) and paraben-PEG, was developed for encapsulating LCS-1...

Mucinous type of epithelial ovarian cancer (MuOC) is a unique subtype with a poor survival outcome in recurrent and advanced stages. The role of type-specific epigenomics and its clinical significance remain uncertain. We analyzed the methylomic profiles of six benign mucinous adenomas, 24 MuOCs, 103 serous type of epithelial ovarian cancers (SeOCs), and 337 nonepithelial ovarian cancers. MuOC and SeOC exhibited distinct DNA methylation profiles comprising 101 genes, 81 of which exhibited low methylation in MuOC and were associated with the response to glucocorticoid, ATP hydrolysis-coupled proton transport, proteolysis involved in the cellular protein catabolic process, and ion transmembrane transport...

BACKGROUND: Spouses of colorectal cancer (CRC) patients could be at increased risk of developing CRC due to shared lifestyle habits with the patients which is a notable risk factor. This study explores the various issues surrounding CRC screening among these spouses. METHODS: A mixed method study comprising in-depth qualitative semi-structured interviews followed by structured quantitative questionnaire was administered to spouses who accompanied CRC patients during their appointments, from January 2016 to February 2017...

Importance: The combination of a triple-drug chemotherapy regimen with an anti-epidermal growth factor receptor (EGFR) agent as a first-line treatment of metastatic colorectal cancer (mCRC) showed promising activity along with safety concerns in single-arm phase 2 trials. The role of maintenance following chemotherapy and anti-EGFR and the optimal regimen to be adopted are not established. Objectives: To evaluate the activity and safety of cetuximab plus modified FOLFOXIRI (mFOLFOXIRI) and explore the role of maintenance with cetuximab or bevacizumab in RAS and BRAF wild-type mCRC...

In the last decades increasing evidence indicated a crucial role of the Wnt/β-catenin signaling in development of midbrain dopaminergic (mDA) neurons. Recently dysregulation of this pathway has been proposed as a novel pathomechanism leading to Parkinson's disease (PD) and some of the molecules participating to the signaling have been evaluated as potential therapeutic targets for PD. Atrial natriuretic peptide (ANP) is a cardiac-derived hormone having a critical role in cardiovascular homeostasis. ANP and its receptors (NPRs) are widely expressed in mammalian central nervous system (CNS) where they could be implicated in the regulation of neural development, synaptic transmission and information processing, as well as in neuroprotection...

NIT1 protein has been reported to be a potential tumour suppressor in tumour progression. However, little is known about the specific role of NIT1 in tumour development and progression. In this study, we confirmed the specific effects of NIT1 in the regulation of colorectal carcinoma cell proliferation. Here, we showed that NIT1 was significantly downregulated in colorectal cancer tissues compared with that in adjacent normal tissues. The decreased expression of NIT1 was significantly correlated with poor differentiation and more serosal invasion...

More than 90% of colorectal cancers carry mutations in Apc that drive tumourigenesis. A 'just-right' signalling model proposes that Apc mutations stimulate optimal, but not excessive Wnt signalling, resulting in a growth advantage of Apc mutant over wild-type cells. Reversal of this growth advantage constitutes a potential therapeutic approach. We utilised intestinal organoids to compare the growth of Apc mutant and wild-type cells. Organoids derived from Apc Min/+ mice recapitulate stages of intestinal polyposis in culture...

PEAK1 is upregulated in multiple human malignancies and has been associated with tumor invasion and metastasis, but little is known about the role of PEAK1 in colorectal cancer (CRC) progression. We investigated the expression pattern, function and regulatory mechanisms of PEAK1 in CRC. Here, we found that PEAK1 is overexpressed in CRC tissues and that high PEAK1 expression predicts poor survival in colon cancer but not rectal cancer. Functionally, silencing PEAK1 inhibits cell proliferation, migration, and invasion in vitro and inhibits the growth of tumor xenografts in nude mice...

Cancer development is usually driven by multiple genetic and molecular alterations rather than by a single defect. In the human colorectal cancer (CRC), series of mutations of genes are involved in the different stages of tumorigenesis. For example, adenomatous polyposis coli (APC) and KRAS mutations have been known to play roles in the initiation and progression of the tumorigenesis, respectively. However, many studies indicate that mutations of these two genes, which play roles in the Wnt/β-catenin and RAS-extra-cellular signal regulated kinase (ERK) pathways, respectively, cooperatively interact in the tumorigenesis in several different cancer types including CRC...

BACKGROUND AND OBJECTIVES: Approximately 30-50% of patients with colorectal cancer develop liver metastasis for which liver resection is the only hope for potential cure. However, hepatic resection is associated with considerable morbidity. The aim was to detect early complications by utilising the neutrophil: lymphocyte ratio (NLR). METHODS: We performed a retrospective cohort study of patients undergoing hepatic resection at a single institution between 2008 and 2016...

In this study, we investigated the in vivo antiproliferative activity of 6,7-dimethoxy-1,2,3,4-tetrahydro-isoquinoline-3-carboxylic acid (M1) in dimethylhydrazine (DMH) induced colorectal carcinoma (CRC) using albino Wistar rats. M1 was administered to DMH induced CRC rats at 10 and 25 mg/kg doses for 15 days. Various physiological, oxidative parameters, histopathology, ELISA, gene and protein expression studies were conducted to evaluate the anti-CRC potential of M1. The histopathology and biochemical tests indicated the protective action of M1 in DMH-induced colon cancer...

Plk2 is a target of p53. Our previous studies demonstrated that with wild-type p53, Plk2 impacts mTOR signaling in the same manner as TSC1, and Plk2-deficient tumors grew larger than control. Other investigators have demonstrated that Plk2 phosphorylates mutant p53 in a positive feedback loop. We investigated Plk2's tumor suppressor functions in relationship to mTOR signaling. Archival specimens from 12 colorectal adenocarcinomas were stained for markers including Plk2, phosphorylated mTOR (serine 2448) and ribosomal S6 (Serine 235/236)...

Endoscopic resection is widely recognized as a first-line treatment for T1 colorectal cancers (CRC), although additional surgical intervention may be indicated based on the risk of lymph node (LN) metastasis. However, risk factors for LN metastasis in T1 CRC not fully established. We investigated the clinicopathological features of T1 CRC and evaluated their association with lymph node metastasis in 133 cases of T1 CRC, consisting of 87 cases with first-line endoscopic resection (EMR) followed by additional surgery and 46 cases with primary surgical resection...

Eruptaneous metastasis is an uncommon presentation of colorectal adenocarcinoma that can occur years after diagnosis of the primary cancer or manifest as the first sign of malignancy. It is essential to diagnose these metastases immediately, as this late-stage development carries a poor prognosis. The scalp is one of the less common sites for skin metastases and nodules may be mistaken for benign entities. In this case report, we report on the case of a 61-year-old woman with CREST syndrome who presented with a cutaneous metastasis to the scalp as the first sign ofcolorectal adenocarcinoma...

Hereditary Nonpolyposis Colorectal Cancer (HNPCC), also known as Lynch Syndrome, is an autosomal dominant, tumor predisposing disorder usuallycaused by germline mutations in mismatch repair (MMR) genes. A subset of HNPCC, Muir-Torre Syndrome (MTS) also involves MMR gene defects and is generally accepted as a variant of HNPCC. MTS is typicallycharacterized by at least one visceral malignancy and one cutaneous neoplasm of sebaceous differentiation, with or without keratoacanthomas. In either version of the disorder, nonfunctional MMR systems lead tothe loss of genomic integrity, marked commonly by mismatches in repetitive DNA sequences, resulting in microsatellite instabilities...
