Abstract
Cancer is the result of genetic abnormalities that cause normal cells to grow into neoplastic cells. Cancer is characterized by several distinct features, such as uncontrolled cell growth, extensive spreading to other parts of the body, and the ability to resist treatment. The scientists have stressed the development of nanostructures as novel therapeutic options in suppressing cancer, in response to the emergence of resistance to standard medicines. One of the specific mechanisms with dysregulation during cancer is autophagy. Nanomaterials have the ability to specifically carry medications and genes, and they can also enhance the responsiveness of tumor cells to standard therapy while promoting drug sensitivity. The primary mechanism in this process relies on autophagosomes and their fusion with lysosomes to break down the components of the cytoplasm. While autophagy was initially described as a form of cellular demise, it has been demonstrated to play a crucial role in controlling metastasis, proliferation, and treatment resistance in human malignancies. The pharmacokinetic profile of autophagy modulators is poor, despite their development for use in cancer therapy. Consequently, nanoparticles have been developed for the purpose of delivering medications and autophagy modulators selectively and specifically to the cancer process. Furthermore, several categories of nanoparticles have demonstrated the ability to regulate autophagy, which plays a crucial role in defining the biological characteristics and response to therapy of tumor cells.

In-vitro and in-silico analysis and antitumor studies of novel Cu(II) and V(V) complexes of N-p-Tolylbenzohydroxamic acid. Int J Biol Macromol 2024; 268:131768.

Abstract
Copper(L2Cu) and vanadium(L2VOCl) complexes of N-p-tolylbenzohydroxamic acid (LH) ligand have been investigated for DNA binding efficacy by multiple analytical, spectral, and computational techniques. The results revealed that complexes as groove binders as evidenced by UV absorption. Fluorescence studies including displacement assay using classical intercalator ethidium bromide as fluorescent probe also confirmed as groove binders. The viscometric analysis too supports the inferences as strong groove binders for both the complexes. Molecular docking too exposed DNA as a target to the complexes which precisely binds L2Cu, in the minor groove region while L2VOCl in major groove region. Molecular dynamic simulation performed on L2Cu complex revealing the interaction of complex with DNA within 20 ns time. The complex stacked into the nitrogen bases of oligonucleotides and the bonding features were intrinsically preserved for longer simulation times. In-vitro cytotoxicity study was undertaken employing MTT assay against the breast cancer cell line (MCF-7). Potential cytotoxic activities were observed for L2Cu and L2VOCl complexes with IC50 values of showing 71 % and 74 % of inhibition respectively.

Abstract
Ovarian cancer is one of the female reproductive system tumors. Chemotherapy is used for advanced ovarian cancer patients; however, drug resistance is a pivotal cause of chemotherapeutic failure. Hence, it is critical to explore the molecular mechanisms of drug resistance of ovarian cancer cells and to ameliorate chemoresistance. Noncoding RNAs (ncRNAs) have been identified to critically participate in drug sensitivity in a variety of human cancers, including ovarian cancer. Among ncRNAs, circRNAs sponge miRNAs and prevent miRNAs from regulation of their target mRNAs. CircRNAs can interact with DNA or proteins to modulate gene expression. In this review, we briefly describe the biological functions of circRNAs in the development and progression of ovarian cancer. Moreover, we discuss the underneath regulatory molecular mechanisms of circRNAs on governing drug resistance in ovarian cancer. Furthermore, we mention the novel strategies to overcome drug resistance via targeting circRNAs in ovarian cancer. Due to that circRNAs play a key role in modulation of drug resistance in ovarian cancer, targeting circRNAs could be a novel approach for attenuation of chemoresistance in ovarian cancer.
