    Luteolin, a Potent Anticancer Compound: From Chemistry to Cellular Interactions and Synergetic Perspectives
    (MDPI, 2022-11-01T00:00:00) Singh Tuli, Hardeep; Rath, Prangya; Chauhan, Abhishek; Sak, Katrin; Aggarwal, Diwakar; Choudhary, Renuka; Sharma, Ujjawal; Vashishth, Kanupriya; Sharma, Sheetu; Kumar, Manoj; Yadav, Vikas; Singh, Tejveer; Yerer, Mukerrem Betul; Haque, Shafiul
    Increasing rates of cancer incidence and the toxicity concerns of existing chemotherapeutic agents have intensified the research to explore more alternative routes to combat tumor. Luteolin, a flavone found in numerous fruits, vegetables, and herbs, has exhibited a number of biological activities, such as anticancer and anti-inflammatory. Luteolin inhibits tumor growth by targeting cellular processes such as apoptosis, cell-cycle progression, angiogenesis and migration. Mechanistically, luteolin causes cell death by downregulating Akt, PLK-1, cyclin-B1, cyclin-A, CDC-2, CDK-2, Bcl-2, and Bcl-xL, while upregulating BAX, caspase-3, and p21. It has also been reported to inhibit STAT3 signaling by the suppression of STAT3 activation and enhanced STAT3 protein degradation in various cancer cells. Therefore, extensive studies on the anticancer properties of luteolin reveal its promising role in chemoprevention. The present review describes all the possible cellular interactions of luteolin in cancer, along with its synergistic mode of action and nanodelivery insight. � 2022 by the authors.

    Molecular mechanisms behind ROS regulation in cancer: A balancing act between augmented tumorigenesis and cell apoptosis
    (Springer Science and Business Media Deutschland GmbH, 2022-11-28T00:00:00) Tuli, Hardeep Singh; Kaur, Jagjit; Vashishth, Kanupriya; Sak, Katrin; Sharma, Ujjawal; Choudhary, Renuka; Behl, Tapan; Singh, Tejveer; Sharma, Sheetu; Saini, Adesh K.; Dhama, Kuldeep; Varol, Mehmet; Sethi, Gautam
    ROS include hydroxyl radicals (HO.), superoxide (O2.), and hydrogen peroxide (H2O2). ROS are typically produced under physiological conditions and play crucial roles in living organisms. It is known that ROS, which are created spontaneously by cells through aerobic metabolism in mitochondria, can have either a beneficial or detrimental influence on biological systems. Moderate levels of ROS can cause oxidative damage to proteins, DNA and lipids, which can aid in the pathogenesis of many disorders, including cancer. However, excessive concentrations of ROS can initiate programmed cell death in cancer. Presently, a variety of chemotherapeutic drugs and herbal agents are being investigated to induce ROS-mediated cell death in cancer. Therefore, preserving ROS homeostasis is essential for ensuring normal cell development and survival. On account of a significant association of ROS levels at various concentrations with carcinogenesis in a number of malignancies, further studies are needed to determine the underlying molecular mechanisms and develop the possibilities for intervening in these processes. � 2022, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
