| Abstract | MicroRNAs (miRs) are a class of non-coding RNAs that function as key regulators of gene expression at the post-transcriptional level. miR-148a has been suggested to be associated with human ovarian cancer, however, the detailed functions of miR148a in ovarian cancer remain to be fully elucidated. The present study aimed to investigate the regulatory mechanism of miR-148a in ovarian cancer cells. Reverse transcriptionquantitative polymerase chain reaction and western blot analysis were conducted to examine the RNA and protein levels, respectively. The luciferase reporter assay was used to determine the target relationship. Cell proliferation and apoptosis assays were additionally conducted. The present study demonstrated that miR148a inhibited cell proliferation and promoted the paclitaxelinduced apoptosis of ovarian cancer cells. Furthermore, protein disulfide isomerase family A, member 3 (PDIA3) was identified as a target gene of miR148a. A fluorescent reporter assay was performed to confirm that miR148a was able to directly bind to the 3'untranslated region of PDIA3 mRNA. In addition, miR148a was frequently downregulated in ovarian cancer tissue, whereas the expression levels of PDIA3 were increased. Knockdown of PDIA3 significantly inhibited the proliferation and promoted the paclitaxelinduced apoptosis of the ovarian cancer cells, whereas overexpression of PDIA3 had the opposite effects. Therefore, the results of the present study suggested that miR148a inhibited the proliferation and promoted the paclitaxelinduced apoptosis of ovarian cancer cells, and this may be partly attributed to direct targeting of PDIA3. |

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.
