    Anticancer effect of Moringa oleifera leaves extract against lung cancer cell line via induction of apoptosis
    (Elsevier, 2022-12) Bhadresha, Kinjal; Thakore, Vaidehi; Brahmbhatt, Jpan; Upadhyay, Vinal; Jain, Nayan; Rawal, Rakesh; Medicine, School of Medicine
    Since ancient times, Moringa oleifera has been a common vegetable in many nations. It has a large number of phenolic compounds with a diverse range of biological activity. It has anticancer properties that can be exploited to create novel medications for the treatment of various malignancies. The current study was conducted to evaluate the in vitro anticancer activities of M. oleifera leaves extracts. The M. oleifera leaves extracts significantly inhibited cell proliferation in the human cancer cell line A549 in a dose-dependent manner. Morphological studies indicated that the extract of moringa leaves stimulated apoptosis as demonstrated by cell shrinkage, blebbing, chromatin condensation, and nuclear fragmentation. Quantitative RT-PCR analyses of Bax and Bcl-2 showed abnormal expression profiles of these genes under various treatment conditions. This study demonstrates that M. oleifera leaves may have the ability to suppress the growth of cancer cells while also enhancing human health and developing new food ingredients. The phytochemicals from M. oleifera leaves can be employed as the primary medications to cure cancer, according to in vitro studies.

    In vitro model of predicting metastatic ability using tumor derived extracellular vesicles; beyond seed soil hypothesis
    (Springer, 2022-11-24) Bhadresha, Kinjal; Upadhyay, Vinal; Brahmbhatt, Jpan; Mughal, Muhammad Jameel; Jain, Nayan; Rawal, Rakesh; Medicine, School of Medicine
    Lung cancer progression is often driven by metastasis, which has resulted in a considerable increase in lung cancer-related deaths. Cell-derived extracellular vesicles (EVs), particularly exosomes, serve key roles in cellular signal transmission via microenvironment, however, their biological relevance in cancer development and metastasis still needs to be clear. Here, we demonstrate that extracellular vesicles (EVs) derived from lung cancer bone metastatic patients exhibited a great capacity to promote the progression of lung cancer cells. We carried out a comprehensive meta-analysis to identify the gene expression profile of bone metastases using publicly available microarray datasets. Furthermore, mRNA expression of six identified genes was quantified by real time PCR in lung cancer with and without bone metastasis and healthy individual derived EVs. In addition, we utilized a very novel approach by to study how lung cancer cells uptake EVs by co-culturing EVs with lung cells. We observed that EVs obtained from bone metastases patients were efficiently ingested by lung cancer cells. Morevore, integration and uptake of these EVs lead to increased lung cancer cell proliferation, migration, invasion, and sphere formation. We discovered that EV uptake increase the expression of SPP1, CD44, and POSTN genes in lung cancer cells. The data obtained from this study, support to the possibility that circulating EVs play a significant role in the formation of the pre-metastatic niche, eventually leading to metastasis.
