Applications of CRISPR Cas-9 in Ovarian Cancer Research.

Ovarian cancer is a highly prevalent malignancy among women and affects a significant population worldwide. Different forms of hormonal treatments or chemotherapies are used to treat ovarian cancer, but the possible side effects, including menopausal symptoms, can be severe, forcing some patients to prematurely stop the treatment. The emerging genome editing technology, known as clustered regularly interspaced short palindromic repeats (CRISPR)-caspase 9 (Cas9), has the potential to treat ovarian cancer via gene editing strategies. Studies have reported CRISPR knockouts of several oncogenes that are involved in the pathogenesis of ovarian cancer, such as BMI1, CXCR2, MTF1, miR-21, and BIRC5, and demonstrate the potential of the CRISPR-Cas9 genome editing technique to effectively treat ovarian cancer. However, there are limitations that restrict the biomedical applications of CRISPR-Cas9 and limit the implementation of Gene therapy for ovarian cancer. These include offtarget DNA cleavage and the effects of CRISPR-Cas9 in non-target, normal cells. This article aims to review the current state of ovarian cancer research, highlight the significance of CRISPR-Cas9 in ovarian cancer treatment, and establish the groundwork for potential clinical research.

Molecular hallmarks of long non-coding RNAs in aging and its significant effect on aging-associated diseases.

Aging is linked to the deterioration of many physical and cognitive abilities and is the leading risk factor for Alzheimer's disease. The growing aging population is a significant healthcare problem globally that researchers must investigate to better understand the underlying aging processes. Advances in microarrays and sequencing techniques have resulted in deeper analyses of diverse essential genomes (e.g., mouse, human, and rat) and their corresponding cell types, their organ-specific transcriptomes, and the tissue involved in aging. Traditional gene controllers such as DNA- and RNA-binding proteins significantly influence such programs, causing the need to sort out long non-coding RNAs, a new class of powerful gene regulatory elements. However, their functional significance in the aging process and senescence has yet to be investigated and identified. Several recent researchers have associated the initiation and development of senescence and aging in mammals with several well-reported and novel long non-coding RNAs. In this review article, we identified and analyzed the evolving functions of long non-coding RNAs in cellular processes, including cellular senescence, aging, and age-related pathogenesis, which are the major hallmarks of long non-coding RNAs in aging.
