Oncol Lett 2018; 14:7759-7766. [PMID: 29344221 PMCID: PMC5755131 DOI: 10.3892/ol.2017.7230] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2016] [Accepted: 08/23/2017] [Indexed: 11/26/2022] Open
Abstract
Livin is a novel member of the inhibitor of apoptosis protein family, which has been identified to be expressed in various malignancies and is suggested to be associated with poor prognostic significance. However, no data are available concerning the significance of livin in mid-distal rectal cancer. In the present study, livin expression, and its association with clinicopathological characteristics and prognosis was examined in patients with mid-distal rectal cancer. Apoptotic susceptibility, invasion capacity and chemosensitivity of LoVo cells were investigated using small interfering RNA (siRNA)-mediated knockdown of livin. It was revealed that livin was highly expressed in mid-distal rectal cancer tissues compared with the normal rectal mucosal tissues. Livin expression was associated with pathological grade, extent of invasion (T stage) and extent of lymph node metastasis (N stage) of tumor, contributing to poor prognosis of mid-distal rectal cancer following surgery. The data suggest that aggressive surgery should be applied in patients with mid-distal rectal cancer with high expression of livin. It was also revealed that knockdown of livin by siRNA increased the apoptotic rate, suppressed invasion of LoVo cells, and decreased the half-maximal inhibitory concentration of oxaliplatin and 5-fluorouracil by ~50% in LoVo cells significantly compared with control groups. The data suggested that a combination of downregulation of livin and anticancer drugs may significantly decrease the toxicity of anticancer drugs. Taken together, the present study indicated that livin may be a promising target in clinical therapy of mid-distal rectal cancer.

Abstract
Aberrant Fhit expression characterizes a large proportion of primary pancreatic ductal adenocarcinomas (PDACs), but fragmentary information is available on Fhit expression during the phenotypic changes of pancreatic ductal epithelium during multistep transformation. We assessed Fhit expression by immunohistochemistry in two different multistep pancreatic carcinogenic processes: pancreatic intraepithelial neoplasia (PanIN) and intraductal papillary mucinous neoplasia (IPMN). We considered 105 surgically treated PDACs/IPMNs and selected 30 samples of non-neoplastic pancreatic parenchyma, 50 PanIN lesions, 30 IPMNs, 15 IPMNs with associated invasive carcinoma, and 60 adenocarcinomas. Normal pancreatic ducts and surrounding acinar cells consistently showed moderate to strong Fhit immunoreactivity. Significant down-regulation of Fhit expression was observed in association with increasing severity of dysplastia/neoplastia in both carcinogenic processes. This was further confirmed by studying multiple lesions obtained from the same surgical specimen. Of 60 PDACs, only 14 showed Fhit expression comparable to normal pancreatic ductal epithelium, while the remainder (77%) showed clearly negative or reduced Fhit expression. This study demonstrates that Fhit down-regulation is an early event in both multistep carcinogenic processes leading to PDAC.

Abstract
Many somatic mutations have been detected in pancreatic ductal adenocarcinoma (PDAC), leading to the identification of some key drivers of disease progression, but the involvement of large genomic rearrangements has often been overlooked. In this study, we performed mate pair sequencing (MPseq) on genomic DNA from 24 PDAC tumors, including 15 laser-captured microdissected PDAC and 9 patient-derived xenografts, to identify genome-wide rearrangements. Large genomic rearrangements with intragenic breakpoints altering key regulatory genes involved in PDAC progression were detected in all tumors. SMAD4, ZNF521, and FHIT were among the most frequently hit genes. Conversely, commonly reported genes with copy number gains, including MYC and GATA6, were frequently observed in the absence of direct intragenic breakpoints, suggesting a requirement for sustaining oncogenic function during PDAC progression. Integration of data from MPseq, exome sequencing, and transcriptome analysis of primary PDAC cases identified limited overlap in genes affected by both rearrangements and point mutations. However, significant overlap was observed in major PDAC-associated signaling pathways, with all PDAC exhibiting reduced SMAD4 expression, reduced SMAD-dependent TGFβ signaling, and increased WNT and Hedgehog signaling. The frequent loss of SMAD4 and FHIT due to genomic rearrangements strongly implicates these genes as key drivers of PDAC, thus highlighting the strengths of an integrated genomic and transcriptomic approach for identifying mechanisms underlying disease initiation and progression.

Abstract
Survivin, a small member of the inhibitors of the apoptosis protein family, is highly deregulated in cancer. It is weakly expressed in normal tissues but very strongly expressed in malignant lesions. Survivin is involved in cell-cycle progression, especially in the G2/M transition, and has anti-apoptotic activity, which correlates with its strong expression in cases with a poor cancer treatment response and poor outcomes. Several therapies that target the survivin transcript or protein are currently being tested in clinical trials. However, focusing new therapies on the origins of survivin overexpression and targeting these upstream deregulations could be more effective. For this reason, it seems important to make an inventory of the transcriptional (de)regulation of survivin. This review will gather the important points concerning the regulation of survivin mRNA expression: structure of the survivin promoter, epigenetic modifications and genetic abnormalities, transcription factors, and signalling pathways that affect survivin mRNA expression.

Abstract
Colorectal cancer (CRC) is a heterogeneous disease and a major contributor to world cancer mortality rates. Molecular subtypes of CRC have become standards for CRC classification and have established prognostic potential. Here, we attempt to corroborate and provide further insight pertinent to the fragile histidine triad (FHIT) gene in microsatellite instable (MSI), microsatellite stable (MSS), and CpG island methylator phenotype (CIMP) CRC subtypes. We employed array comparative genomic hybridization and multiplex ligation-dependent probe amplification (MLPA) techniques to survey genomic aberrations in FHIT gene and their effects on FHIT protein expression using immunohistochemistry (IHC) in a CRC cohort. We further studied FHIT protein expression by IHC in a larger CRC cohort defined for its mismatch repair (MMR) protein expression and genomic methylation profiles. Our results show FHIT genomic deletions centered in exons 4 and 5 in most of MSI-CRC samples. Moreover, we confirmed the significant association of FHIT protein expression diminution (p=0.035) with MSI-CRC. In the larger cohort, reduced FHIT protein expression was significantly associated with CIMP-high subtype of CRC (p=0.009) and loss of PMS2 protein expression (p=0.017). We conclude that FHIT expression may be a valuable marker for CRC subtyping, and its diagnostic, prognostic, and therapeutic potential should be perused.

Abstract
AIM: To characterize aberrant crypt focus (ACF) in adjoining mucosa in sporadic colorectal carcinoma and to evaluate fragile histidine triad (Fhit) protein and Ki67.
METHODS: ACF was identified grossly and classified histologically in 75 resected specimens. ACF was typed into hyperplastic ACF (HACF) and dysplastic ACF (DACF). Sections of ACF, carcinoma and normal colonic mucosa as control were studied for Fhit and Ki67 expressions by immunohistochemistry and were grouped according to staining intensity and the number of positive stained cells observed in different histological groups. Comparison was done between the different groups by Pearson’s χ2 test and γ test for the ordinal data. P value < 0.05 was considered as significant.
RESULTS: Age range was 40 to 86 years in males (mean = 43.36) and 45 to 70 years in females (mean = 56). HACF was identified in all cases studied in the non-tumorous colonic mucosa; ACF was observed as non-contiguous scattered foci, which supports the hypothesis of acquisition of single focus monoclonality by colonic epithelial cells in tumor generation. Twenty-four (32%) had DACF and were observed as closure to carcinoma foci. Intensity of Fhit expression: (1) HACF - 40% exhibited strong intensity, similar to normal, moderate in 36% and weak in 24%; (2) DACF - strong in 25%, moderate in 37.5% and weak in 37.5%; and (3) carcinoma - negative in 16%, strong in 43% and moderate and weak in 28.5% each. Significant difference was observed in intensity of the Fhit protein expressions by HACF and DACF (P < 0.05). Tumor in older patients showed a stronger Fhit intensity compared to younger patients (P = 0.036). Vegetarian diet intake and non-smokers showed stronger Fhit intensities. Advanced stage tumor, non-vegetarian diet and younger age was associated with loss of Fhit protein. Ki67 positivity was an extended crypt pattern in HACF and DACF showed extension up to the neck region of the crypts and surface epithelium. Carcinomas showed a marked increase in Ki67 expression (P < 0.05). Fhit protein had an inverse association with Ki67 expression.
CONCLUSION: Weaker Fhit intensity was associated with smoking, non-vegetarian diet intake and increasing Ki67 expression. Loss of Fhit protein expression is possibly influenced by environmental factors like smoking and non-vegetarian diet intake.

Abstract
BACKGROUND The relationship between the expression of CD133 and fragile histidine triad (FHIT) or prognosis in Chinese colorectal adenocarcinoma is unknown and needs to be explored. MATERIAL AND METHODS The samples of colorectal adenocarcinoma from 200 Chinese patients with follow-up were analyzed for the expression of CD133 and FHIT proteins by immunohistochemical method. RESULTS CD133 was highly expressed in up to 42.0%(84/200) of this group of colorectal adenocarcinomas. The expression of CD133 was significantly higher in carcinoma than in normal (P=0.0001) and in adenomatous mucosas (P=0.004). CD133 positively corresponds to histological grade, clinical stage, regional lymphatic metastasis, and distant metastasis (all P<0.05). The mean overall survival time was shorter in patients with CD133 high expression than in those with CD133 low expression (P00.0001). The expression of CD133 was inversely correlative with that of FHIT (r=-0.464, P=0.0001) in colorectal adenocarcinoma. CD133 was an independent prognostic factor (P=0.0001). CONCLUSIONS The expression of CD133 may be inversely correlated with the expression of FHIT. It is suggested that CD133 may play an important role in the evolution of colorectal adenocarcinoma and be considered as a potential marker for the prognosis.

Abstract
BACKGROUND Loss of expression of fragile gene products, Fhit and Wwox, occurs in many cancer types, with loss exhibited early in the neoplastic process in some. Wwox has been understudied in pancreatobiliary cancers, especially in relation to other involved tumor suppressors. We have assessed the status of the Fhit and Wwox proteins encoded by DNA damage susceptible chromosome fragile sites encompassed by FHIT and WWOX tumor suppressor genes. METHODS Pancreatic, gallbladder and ampullary cancers, normal pancreas, chronic pancreatitis, and benign gallbladder specimens were stained for expression of Fhit, Fhit effector protein Fdxr, Wwox, and other tumor suppressors by immunohistochemistry, and comparisons were made between benign and malignant tissue. Correlations of expression among proteins and clinicopathologic features were sought using Spearman's rank order. Survival curves were created using the Kaplan-Meier method and compared by log-rank analysis. Predictors of survival were determined using multivariate Cox proportional hazards analysis. RESULTS Fhit and Wwox were ubiquitously expressed in benign samples and significantly and coordinately reduced in pancreatic, gallbladder, and ampullary cancers. In pancreatic cancers, Fdxr expression was positively correlated with Fhit and Wwox expression. Neither Fhit nor Wwox expression correlated with expression of other tumor suppressors or with clinicopathologic characteristics measured. CONCLUSION Loss of Fhit and Wwox expression does not predict tumor progression or patient survival, suggesting that loss of expression of genes at the exquisitely replication stress sensitive chromosome fragile regions is an early event in the pathogenesis of cancers of the gallbladder, pancreas, and ampulla.
