Prognostic Value of Immunohistochemical Expression of MTAP and AKIP1 in IDH1 Mutant Astrocytoma

BACKGROUND

Definite treatment for glioma is not exist, and with increased drug resistance, more effort should be paid to identify new prognostic biomarkers and molecular targets for therapy for glioma patients.

AIM

The current study aimed to evaluate the immunohistochemical (IHC) expression of MTAP and A-Kinase Interacting Protein 1 (AKIP1) in astrocytoma and to investigate their association with the clinicopathological characters of these cases.

METHODS

Totally 66 cases of astrocytoma patients involved in this study. Cases underwent tumor resection and tissue sections were stained with MTAP, AKIP1 and IDH1 by IHC and evaluated in different grades of astrocytoma and their association with survival and response to therapy was investigated.

RESULTS

High AKIP1 expression was positively correlated with treatment resistance and progressive disease. Positive IDH and retained MTAP expressions had shown better treatment response rather than negative IDH and lost MTAP. High AKIP, negative IDH and loss of MTAP expressions were significantly associated with poor survival outcome.

CONCLUSION

Irrespective to grade and IDH status, the loss of MTAP immunoreactivity and high AKIP1 expression are predictive factors in astrocytoma, and they may be used as a biomarker for guiding astrocytoma management and prognosis surveillance.

Clinicopathologic Impact of NANOG, ZEB1, and EpCAM Biomarkers on Prognosis of Serous Ovarian Carcinoma

OBJECTIVES

Serous ovarian carcinoma (SOC) is a biologically heterogeneous with different genomic and molecular profiles, beside clinical response to the chemotherapy with subsequent in obstacles in starting unified, acceptable treatments and so we assess immunoexpression of Nanog, ZEB1, and EpCAM in SOC.

METHODS

In this study, the immunoexpression of Nanog, ZEB1, and EpCAM was studied in 60 cases of SOC. Overall survival (OS), disease-free survival (DFS) data and response to chemotherapy were  analyzed.

RESULTS

NANOG was immunostained in 65% of the cases with a significant association with tumor grade, lymph node metastasis, and FIGO stage (p < 0.001 for each). ZEB1 showed moderate- high expression in 58.3% of the cases with significant up-regulation of ZEB1 expression with SOC grade, nodal metastasis, and SOC FIGO stage (p<0.001). EpCAM revealed high expression in 60% of the cases with significant association with higher grade, nodal metastasis, and advanced stage (p < 0.001 for each). Up-regulation of Nanog was significantly associated with response to chemotherapy, relapse, shorter OS and DFS (p < 0.001 for each). ZEB1 overexpression exhibited a significant association with response to chemotherapy (p= 0.012), relapse, shorter OS and DFS (p<0.001 for each). Moreover, the high EpCAM had a significant association with response to chemotherapy (p= 0.043), relapse (p < 0.001) shorter OS (p=0.006) and DFS (p< 0.001).

CONCLUSIONS

Up-regulation of Nanog and ZEB-1 and EpCAM perhaps promote an aggressive SOC with a high risk of relapse and unfavorable response to standard chemotherapy regimen.

MIR-379-5p Expression in Endometrial Cancer and Its Correlation with ROR1 Expression

OBJECTIVE

To asses miR-379-5p expression in endometrial cancer (EC) and its correlation with ROR1 expression and to investigate the relation between miR-379-5p and ROR1 expressions and the clinicopathological picture of EC.

METHODS

Fifty female of EC were joined to this study. The gene expression of miR-379-5p (by quantitative real time-PCR) and ROR1 (by quantitative real time-PCR and immunohistochemistry) were studied in EC and normal nearby endometrial tissue.

RESULTS

The gene expression of miR-379-5p was significantly downregulated while that of ROR1 was significantly upregulated in EC tissues compared to adjacent normal endometrial tissues. Furthermore, miR-379 and ROR1 expressions significantly associated with tumor stage (P< 0.045), grade (P< 0.001), myometrial invasion (P <0.001) and LN metastasis (P< 0.034). In addition, miR-3795p and ROR1 gene expression were negatively correlated (r = -0.746, P < 0.001).

CONCLUSIONS

In EC, miR-379-5p can be used as a diagnostic marker, and ROR1 could be a potential target of miR-379-5p.

Partnership of the community in support of health for all

Health for all is a people-based approach to health which considers the community as its focus. Community partnership is an important principle of health for all. This paper describes the many aspects of community partnership and gives examples of community partnerships initiatives in the World Health Organization Eastern Mediterranean Region, such as the basic development needs approach. The main agenda of community partnership for health for all is discussed and some opportunities conductive to community partnership in the Region are outlined
