Biomarkers towards Ovarian Cancer Diagnostics: Present and Future Prospects BABT
Rastogi,Meenal; Gupta,Sameer; Sachan,Manisha.
ABSTRACT Ovarian carcinoma accounts for highest mortality of all gynecologic malignancies as the disease is asymptomatic until late stages. Biomarkers such as CA-125 and HE4 are being currently used for diagnosis of ovarian cancer, but they show contradicting diagnostic accuracy. Therefore other biomarkers have been investigated for early detection of this disease, but no success has been obtained and no test has yet been recommended for screening a general population. In this instance, aptamers can be effectively used to identify tumor-specific antigens for early diagnosis and targeted therapy of ovarian cancer. This article provides an overview of the biomarkers/panels being explored as well as the potential of aptamers to improve current long-term...

Epigenetic Modifications: Therapeutic Potential in Cancer BABT
Sachan,Manisha; Kaur,Manpreet.
Epigenetic modifications and alterations in chromatin structure and function contribute to the cumulative changes observed as normal cells undergo malignant transformation. These modifications and enzymes (DNA methyltransferases, histone deacetylases, histone methyltransferases, and demethylases) related to them have been deeply studied to develop new drugs, epigenome-targeted therapies and new diagnostic tools. Epigenetic modifiers aim to restore normal epigenetic modification patterns through the inhibition of epigenetic modifier enzymes. Four of them (azacitidine, decitabine, vorinostat and romidepsin) are approved by the U.S. Food and Drug Administration. This article provides an overview about the known functional roles of epigenetic enzymes in cancer...

Methylation of the Sox9 and Oct4 promoters and its correlation with gene expression during testicular development in the laboratory mouse Genet. Mol. Biol.
Pamnani,Mamta; Sinha,Puja; Singh,Alka; Nara,Seema; Sachan,Manisha.
Abstract Sox9 and Oct4 are two important regulatory factors involved in mammalian development. Sox9, a member of the group E Sox transcription factor family, has a crucial role in the development of the genitourinary system, while Oct4, commonly known as octamer binding transcription factor 4, belongs to class V of the transcription family. The expression of these two proteins exhibits a dynamic pattern with regard to their expression sites and levels. The aim of this study was to investigate the role of de novo methylation in the regulation of the tissue- and site-specific expression of these proteins. The dynamics of the de novo methylation of 15 CpGs and six CpGs in Sox9 and Oct4 respectively, was studied with sodium bisulfite genomic DNA sequencing in...
