Abstract
Cisplatin (DDP) is the first-line chemotherapeutic agent against lung cancer. However, the therapeutic effect of DDP loses over time due to the acquired drug resistance in non-small cell lung cancer (NSCLC) cells. In recent years, the role of the traditional Chinese medicine (TCM) cordycepin (Cor) in cancer treatment has been attracting attention. However, the effects of Cor on DDP resistance in NSCLC are unclear. In the present study, we aimed to investigate the effects of Cor in combination with DDP on cell proliferation and apoptosis in NSCLC and explore possible underlying mechanisms. The cell proliferation and apoptosis were analyzed in NSCLC parental (A549) and DDP-resistant (A549DDP) cells treated with DDP alone or in combination with Cor both in vitro and in vivo. Different genes and signaling pathways were investigated between DDP-sensitive and DDP-resistant A549 cells by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analysis. The perturbations of the MAPK and PI3K-AKT signaling pathways were evaluated by Western blot analysis. Our data showed that Cor markedly enhanced DDP inhibition on cell proliferation and promotion of apoptosis compared to the DDP-alone group in both A549 and A549DDP cells. The synergic actions were associated with activation of AMPK; inhibition of AKT, mTOR, and downstream P709S6K; and S6 phosphorylation in the AKT pathway compared with DDP alone. Collectively, combination of Cor and DDP has a synergistic effect in inhibiting proliferation and promoting apoptosis of NSCLC cells in the presence or absence of DDP resistance. The antitumor activity is associated with activation of AMPK and inhibition of the AKT pathway to enhance DDP inhibition on NSCLC. Our results suggested that Cor in combination with DDP could be an additional therapeutic option for the treatment of DDP-resistant NSCLC.

Abstract
BACKGROUND HER2 is an oncoprotein which is overexpressed in several cancers including breast and stomach. Several studies have shown that HER2 is overexpressed in gallbladder cancer and in precancerous lesions. The present study was undertaken to assess pattern and level of expression of HER2 in metaplasia, dysplasia, and different stages of gallbladder carcinoma, which would determine its suitability as a prognostic biomarker in neoplastic transformation of gallbladder epithelium. The study was also aimed at to find the significance of Ki-67 index in these lesions. METHODS AND MATERIALS One hundred and twenty-eight patients who underwent cholecystectomy comprised the study group. Among them, 108 (84.4%) specimens showing metaplasia, dysplasia, and carcinoma on routine histopathology were considered as cases and 20 (15.6%) specimens of chronic cholecystitis having non-metaplastic mucosa were considered as control. Immunohistochemistry (IHC) was performed for HER2 and Ki-67. For HER2 interpretation ASCO/CAP guideline for breast cancer was followed. Chi-square test was used to find out the significance of HER2 expression in dysplasia/metaplasia/carcinoma. The ANOVA and Tukey-Kramer Multiple Comparisons Test were used for determining the association of Ki-67 with malignant transformation. RESULTS AND CONCLUSIONS Overexpression of HER2 was observed in 48% (n = 12) of adenocarcinomas, 58% (n = 7) of high-grade dysplasia, 47% (n = 8) of low-grade dysplasia, and 74% (n = 25) of intestinal metaplasia. Ki-67 index increases in a non-linear fashion as the precursor lesions progress toward malignancy. In the future, these markers might be used as a prognostic biomarker for gallbladder carcinoma and its precursor lesions and it might become a valid indication for targeted therapies for gallbladder cancer.

Abstract
BACKGROUND Gallbladder cancer is the most common malignant cancer of the bile ducts and third most common gastrointestinal malignant in the world for public health. Its relatively low incidence and confused symptoms result in advanced disease at the time of presentation, contributing to poor prognosis and reduced survival associated with this disease. The main function of the gallbladder is to store excreted bile acids from the liver in preparation for a meal. Its main risk factor is prolonged exposure to biliary calculations, although bacterial infections and other inflammatory conditions are associated. Chronic inflammatory bowel conditions are associated with gallbladder cancer. T stage translates to identifying residual disease at reoperation for incidental gallbladder cancer and residual disease negatively affects survival. CONCLUSION It is the most common cancer of gallbladder, gallbladder cancer remains a rare disease. Gallbladder cancer is a rare disease that can be accidentally diagnosed after cholecystectomy or accidentally, often with more advanced disease. The prognosis is generally extremely poor and improvements in surgical resection of this approach have to be re-evaluated, while the role of chemotherapy and radiotherapy remains controversial.

Mol Med Rep 2015; 12:7303-9. [PMID: 26459875 PMCID: PMC4626199 DOI: 10.3892/mmr.2015.4354] [Citation(s) in RCA: 7] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2014] [Accepted: 01/09/2015] [Indexed: 12/21/2022] Open
Abstract
Ki-67 is a nuclear protein that is expressed during the G1, S, G2 and M phases of the mitotic cell cycle. A previous study categorized tumor infiltration patterns (INF), of which INFc indicated cancer nests exhibiting infiltrative growth and an unclear boundary between tumor tissue and surrounding healthy tissue. The present study used the Ki-67 labeling index (Ki-67 LI) as an indicator of cell proliferation, in order to examine the factors affecting INF in lung squamous cell carcinoma (SqCC). SqCC specimens (89) were classified into two groups: High-grade cell proliferation (Ki-67 LI ≥30%) and low-grade cell proliferation (Ki-67 LI <30%). However, a high Ki-67 LI was significantly associated with cases that had an INFc component [INFc(+); P=0.03]. Univariate analyses indicated that INFc(+) was a predictor of venous invasion [P=0.032; odds ratio (OR), 2.615; 95% confidence interval (95% CI), 1.085–6.305], scirrhous stromal type (P<0.001; OR, 6.462; 95% CI, 2.483–16.817) and high Ki-67 LI (P=0.018; OR, 12.543; 95% CI, 1.531–102.777). Multivariate logistic analyses indicated that high Ki-67 LI was the strongest predictor of INFc(+) (P=0.028; OR, 8.027; 95% CI, 1.248–51.624). In conclusion, high-grade cell proliferation activity may contribute to aggressive infiltrative growth of lung SqCC.

Expression of epidermal growth factor receptor, p53, Bcl2, vascular endothelial growth factor, cyclooxygenase-2, cyclin D1, human epidermal receptor-2 and Ki-67: Association with clinicopathological profiles and outcomes in gallbladder carcinoma. J Carcinog 2014; 13:10. [PMID: 25225463 PMCID: PMC4163917 DOI: 10.4103/1477-3163.139450] [Citation(s) in RCA: 15] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/28/2014] [Accepted: 07/24/2014] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND The present study observed the expression levels of epidermal growth factor receptor (EGFR), p53, Bcl2, vascular endothelial growth factor (VEGF), cyclooxygenase-2 (cox-2), cyclin D1, human epidermal receptor-2 (HER-2) and Ki-67 in gallbladder carcinoma (GBC) and their association with clinicopathological profiles and disease outcomes. MATERIALS AND METHODS Fifty consecutive samples of cholecystectomy/biopsies from GB bed (archived formalin fixed paraffin embedded tissue blocks of different stages of GBC) were included, and patient details related to their demographic profile, investigations, tumor profile, treatment, and follow-up were recorded. Immunohistochemistry was performed to study the expression levels. RESULTS Overexpression of EGFR, p53, Bcl2, VEGF, cox-2, cyclin D1 and HER-2 was observed as 74%, 44%, 8%, 34%, 66%, 64%, and 4%, respectively. Association of Bcl2 overexpression in mucinous morphology (40%, P = 0.045), cox-2 overexpression in early stage (I/II) tumors (87.5%, P = 0.028) and VEGF overexpression in alive patients (47.1%, P = 0.044) was observed. Co-expression of EGFR and p53 were statistically significant (P = 0.033). Ki-67 labeling index was significantly higher in patients in age group <40 years (P = 0.027), and poorly differentiated tumors (P = 0.023). Advanced disease and poorly differentiated tumors showed a significantly poor median survival (P < 0.05). CONCLUSION EGFR, cox-2 and cyclin D1 were largely overexpressed. Advanced tumor stages and poorly differentiated tumors are predictors of poor survival.
