    Apoptotic and antimetastatic effect of cucurbitacins in cancer: recent trends and advancement
    (Springer Science and Business Media Deutschland GmbH, 2023-04-03T00:00:00) Kumar, Ajay; Sharma, Bunty; Sharma, Ujjawal; Parashar, Gaurav; Parashar, Nidarshana Chaturvedi; Rani, Isha; Ramniwas, Seema; Kaur, Satwinderjeet; Haque, Shafiul; Tuli, Hardeep Singh
    The Cucurbitaceae family produces a class of secondary metabolites known as cucurbitacins. The eight cucurbitacin subunits are cucurbitacin B, D, E, I, IIa, L glucoside, Q, and R with the most significant anticancer activity. They are reported to inhibit cell proliferation, invasion, and migration; induce apoptosis; and encourage cell cycle arrest, as some of their modes of action. The JAK-STAT3, Wnt, PI3K/Akt, and MAPK signaling pathways, which are essential for the survival and apoptosis of cancer cells, have also been shown to be suppressed by cucurbitacins. The goal of the current study is to summarize potential molecular targets that cucurbitacins could inhibit in order to suppress various malignant processes. The review is noteworthy since it presents all putative molecular targets for cucurbitacins in cancer on a single podium. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    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.

    (Springer Science and Business Media Deutschland GmbH, 2023-11-03T00:00:00) Haque, Shafiul; Hussain, Arif; Joshi, Hemant; Sharma, Ujjawal; Sharma, Bunty; Aggarwal, Diwakar; Rani, Isha; Ramniwas, Seema; Gupta, Madhu; Tuli, Hardeep Singh
    Background: Melittin is a water-soluble cationic peptide derived from bee venom that has been thoroughly studied for the cure of different cancers. However, the unwanted interactions of melittin produce hemolytic and cytotoxic effects that hinder their therapeutic applications. To overcome the shortcomings, numerous research groups have adopted different approaches, including conjugation with tumor-targeting proteins, gene therapy, and encapsulation in nanoparticles, to reduce the non-specific cytotoxic effects and potentiate their anti-cancerous activity. Purpose: This article aims to provide mechanistic insights into the chemopreventive activity of melittin and its nanoversion in combination with standard anti-cancer drugs for the treatment of cancer. Methods: We looked over the pertinent research on melittin's chemopreventive properties in online databases such as PubMed and Scopus. Conclusion: In the present article, the anti-cancerous effects of melittin on different cancers have been discussed very nicely, as have their possible mechanisms of action to act against different tumors. Besides, it interacts with different signal molecules that regulate the diverse pathways of cancerous cells, such as cell cycle arrest, apoptosis, metastasis, angiogenesis, and inflammation. We also discussed the recent progress in the synergistic combination of melittin with standard anti-cancer drugs and a nano-formulated version of melittin for targeted delivery to improve its anticancer potential.

    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.

    Potential use of cidofovir, brincidofovir, and tecovirimat drugs in fighting monkeypox infection: recent trends and advancements
    (Springer Science and Business Media Deutschland GmbH, 2023-10-14T00:00:00) Rani, Isha; Joshi, Hemant; Sharma, Ujjawal; Kaur, Jagjit; Sood, Shivani; Ramniwas, Seema; Chauhan, Abhishek; Abdulabbas, Hadi Sajid; Tuli, Hardeep Singh
    Recent years have witnessed the rise of more recent pandemic outbreaks including COVID-19 and monkeypox. A multinational monkeypox outbreak creates a complex situation that necessitates countermeasures to the existing quo. The first incidence of monkeypox was documented in the 1970s, and further outbreaks led to a public health emergency of international concern. Yet as of right now, neither vaccines nor medicines are certain to treat monkeypox. Even the inability of conducting human clinical trials has prevented thousands of patients from receiving effective disease management. The current state of the disease�s understanding, the treatment options available, financial resources, and lastly international policies to control an epidemic state are the major obstacles to controlling epidemics. The current review focuses on the epidemiology of monkeypox, scientific ideas, and available treatments, including potential monkeypox therapeutic methods. As a result, a thorough understanding of monkeypox literature will facilitate in the development of new therapeutic medications for the prevention and treatment of monkeypox. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

    Preparation of a Pt(II)-3-Hydroxy-2-tolyl-4H-chromen-4-one Complex Having Antimicrobial, Anticancerous, and Radical Scavenging Activities with Related Computational Studies
    (American Chemical Society, 2023-08-22T00:00:00) Mohmad, Masrat; Agnihotri, Nivedita; Kumar, Vikas; Azam, Mohammad; Kamal, Raj; Kumar, Ashish; Sharma, Ujjawal; Javed, Saleem; Muthu, Sambantham; Min, Kim
    A novel benzopyran-based platinum (II)-3-hydroxy-2-tolyl-4H-chromen-4-one (HToC) complex has been prepared and studied by UV-visible spectrophotometry. The study is based on the colored complexation between Pt(II) and HToC in the pH range of 8.92-9.21, resulting in the formation of a stable binary yellow complex exhibiting ?max at 509-525 nm. The formed complex maintains linearity between 0.0 and 1.8 ?g Pt(II) mL-1. The well-known qualitative analytical methods, including Job�s method of continuous variations and the mole ratio approach, have both proven that the stoichiometry of the complex is 1:2 [Pt(II)/HToC]. Hence, the analytical results suggest that the formed platinum complex exhibits a square planar geometry. The values of various attributes corresponding to spectrophotometric studies and statistical calculations, such as the molar extinction coefficient (6.790 � 104 L mol-1 cm-1), Sandell�s sensitivity (0.0029 ?g Pt(II) cm-2), standard deviation (� 0.0011), RSD (0.317%), limit of detection (0.0147 ?g mL-1) and correlation coefficient (0.9999), show that the performed study satisfies all of the criteria for good sensitivity, versatility, and cost-effectiveness. In order to have an apprehension of the molecular geometry and other structural specifics of the complex, DFT studies have been carried out. The in vitro anticancer potential of the ligand and its platinum complex in the human breast cancer cell line (T-27D), as determined by the MTT assay, reveals that the complex has better antiproliferative potential than the ligand. The antimicrobial potential of the complex has been successfully tested against both Gram-positive and -negative bacteria. Antioxidant capacity results suggest the better radical scavenging capacity of the complex than that of the ligand. � 2023 The Authors. Published by American Chemical Society

    Role of Hedgehog and Hippo signaling pathways in cancer: A special focus on non-coding RNAs
    (Academic Press, 2022-10-28T00:00:00) Sharma, Uttam; Tuli, Hardeep Singh; Uttam, Vivek; Choudhary, Renuka; Sharma, Bunty; Sharma, Ujjawal; Prakash, Hridayesh; Jain, Aklank
    Despite advanced clinical and translational oncology research, mortality rates are still increasing worldwide. Recently, a class of non-coding RNAs (ncRNAs), such as microRNAs (miRNAs), long non-coding RNAs (lncRNAs), and circular RNAs (circRNAs), have been well investigated in regulating biological, molecular, and cellular signaling pathways. This review article provided the current research progress on how miRNAs, lncRNAs, and circRNAs regulate Hedgehog (Hh) and Hippo signaling pathways in various cancers. These ncRNAs target both pathways' key downstream molecules and may be used for targeted cancer treatment. Moreover, Hh and Hippo signaling pathways crosstalked with each other through Gli1 of Hh pathways and YAP1/TEAD molecules of Hippo pathways during cancer progression. Additionally, Hh and Hippo signaling pathways regulate resistance against the chemo, radio, and immune therapies for several types of cancer via inducing GLI and YAP/TAZ proteins level. Therefore, to improve the treatment regime, we presented the role of various prominent phytochemicals such as curcumin, resveratrol, genistein, quercetin, paclitaxel, and silibinin in regulating lncRNAs, miRNAs, circRNA through Hedgehog and Hippo signaling pathways� constituents in cancers. We believe that knowledge obtained from this review may help make new drugs for cancer treatment in the future. � 2022 Elsevier Ltd

    Temozolomide and flavonoids against glioma: from absorption and metabolism to exosomal delivery
    (Springer Science and Business Media Deutschland GmbH, 2023-08-11T00:00:00) Verma, Priyanka; Joshi, Hemant; Singh, Tejveer; Sharma, Bunty; Sharma, Ujjawal; Ramniwas, Seema; Rana, Rashmi; Gupta, Madhu; Kaur, Ginpreet; Tuli, Hardeep Singh
    Patients with glioblastoma multiforme and anaplastic astrocytoma are treated with temozolomide. Although it has been demonstrated that temozolomide increases GBM patient survival, it has also been connected to negative immune-related adverse effects. Numerous research investigations have shown that flavonoids have strong antioxidant and chemo-preventive effects. Consequently, it might lessen chemotherapeutic medicines� side effects while also increasing therapeutic effectiveness. The need for creating innovative, secure, and efficient drug carriers for cancer therapy has increased over time. Recent research indicates that exosomes have enormous potential to serve as carriers and cutting-edge drug delivery systems to the target cell. In recent years, researchers have been paying considerable attention to exosomes because of their favorable biodistribution, biocompatibility, and low immunogenicity. In the present review, the mechanistic information of the anti-glioblastoma effects of temozolomide and flavonoids coupled with their exosomal delivery to the targeted cell has been discussed. In addition, we discuss the safety aspects of temozolomide and flavonoids against glioma. The in-depth information of temozolomide and flavonoids action via exosomal delivery can unravel novel strategies to target Glioma. � 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.
