    Impact of noncoding RNAs on cancer directed immune therapies: Now then and forever
    (John Wiley and Sons Inc, 2022-04-30T00:00:00) Roy, Roshan Kumar; Yadav, Rakhi; Sharma, Uttam; Wasson, Mishi Kaushal; Sharma, Ashok; Tanwar, Pranay; Jain, Aklank; Prakash, Hridayesh
    Accumulating evidence demonstrates that the host genome's epigenetic modifications are essential for living organisms to adapt to extreme conditions. DNA methylation, covalent modifications of histone and interassociation of noncoding RNAs facilitate the cellular manifestation of epigenetic changes in the genome. Out of various factors involved in the epigenetic programming of the host, noncoding RNAs (ncRNAs) such as microRNA (miRNA), long noncoding RNA (lncRNA), circular RNA, snoRNA and piRNA are new generation noncoding molecules that influence a variety of cellular processes like immunity, cellular differentiation and tumor development. During tumor development, temporal changes in miRNA/lncRNA rheostat influence sterile inflammatory responses accompanied by the changes in the carcinogenic signaling in the host. At the cellular level, this is manifested by the upregulation of inflammasome and inflammatory pathways, which promotes cancer-related inflammation. Given this, we discuss the potential of lncRNAs, miRNAs, circular RNA, snoRNA and piRNA in regulating inflammation and tumor development in the host. � 2022 UICC.

    Galangin: A metabolite that suppresses anti-neoplastic activities through modulation of oncogenic targets
    (SAGE Publications Inc., 2021-12-14T00:00:00) Tuli, Hardeep Singh; Sak, Katrin; Adhikary, Shubham; Kaur, Ginpreet; Aggarwal, Diwakar; Kaur, Jagjit; Kumar, Manoj; Parashar, Nidarshana Chaturvedi; Parashar, Gaurav; Sharma, Uttam; Jain, Aklank
    With the dramatic increase in cancer incidence all over the world in the last decades, studies on identifying novel efficient anti-cancer agents have been intensified. Historically, natural products have represented one of the most important sources of new lead compounds with a wide range of biological activities. In this article, the multifaceted anti-cancer action of propolis-derived flavonoid, galangin, is presented, discussing its antioxidant, anti-inflammatory, antiproliferative, pro-apoptotic, anti-angiogenic, and anti-metastatic effects in various cancer cells. In addition, co-effects with standard chemotherapeutic drugs as well as other natural compounds are also under discussion, besides highlighting modern nanotechnological advancements for overcoming the low bioavailability issue characteristic of galangin. Although further studies are needed for confirming the anti-cancer potential of galangin in vivo malignant systems, exploring this natural compound might open new perspectives in molecular oncology. � 2021 by the Society for Experimental Biology and Medicine.
