| Abstract | Kallikrein-related peptidase 14 (KLK14) is a member of the tissue kallikrein family of proteases, which are associated with the pathogenesis of malignant tumors and are over-expressed in ovarian carcinoma. However, the mechanism through which KLK14 is implicated in ovarian cancer remains unclear. The aim of the present study was to investigate the effects of KLK14 gene inhibition by small interfering RNA (siRNA) on the growth, apoptosis and invasion of ovarian carcinoma cells in vitro. KLK14 siRNA was transiently transfected into SK-OV-3 and OVCAR-3 ovarian carcinoma cells for 48 h. The expression of KLK14 was determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western blot analysis. Cell proliferation, apoptosis and invasion were examined by MTT, flow cytometry and Matrigel assay, respectively. The expression of survivin, caspase 9, cleaved caspase 3 and MMP2 protein was measured by Western blot analysis. The expression of KLK14 was significantly downregulated by siRNA in SK-OV-3 and OVCAR-3 cells at both the mRNA and protein levels. Following transfection with KLK14 siRNA, cell growth and invasion were significantly suppressed, and cell apoptosis was markedly induced. The expression of survivin and MMP2 was decreased, while the espression of caspase 9 and cleaved caspase 3 was increased. These results indicate that KLK14 is implicated in the malignant behavior of ovarian carcinoma cells in vitro, and that KLK14 may serve as a target for therapy of ovarian carcinoma. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
