This study aims to conduct molecular analysis of the L1 gene from HR-HPV16 samples collected in Lahore, Pakistan, and to identify potential inhibitors against the L1 protein through in-silico analysis. The L1 gene was amplified using PCR (Polymerase Chain Reaction), followed by gel purification and Sanger sequencing. Nucleotide and amino acid sequence alignments were used to assess variant regions. In silico tools, including ADMET, CB DOCK 2 and Maestro Schrodinger, were employed to evaluate different parameters of various compounds with L1 protein. The study identified mutations in L1 sequences, including V357G, V359G, S369A, AND C371W, which could impact HPV-16 behavior and cancer development. Neoechinulin was identified as a promising HPV16 L1 capsid protein inhibitor with the highest binding energy score (-7.6 kcal/mol) against the L1 protein, suggesting potential antiviral efficacy. These mutations may alter the structural integrity of the L1 protein, potentially influencing HPV-16 infectivity and its role in cervical cancer progression, while virtual screening method demonstrated a cost- effective approach for discovering biologically impactful compounds.

Primary TAMs isolated from ascites of ovarian cancer patients were co-cultured with SKOV3/OVCAR-3 cancer cells.

Resistance to conventional therapies continues to be a major obstacle in colorectal cancer treatment, highlighting the need for novel therapeutic strategies to enhance efficacy. This study aims to bridge this gap by exploring a multi-target inhibition approach using naturally derived electrophilic compounds, offering a potential solution to overcome drug resistance. Key CRC-covalent targets-EGFR, SRC, AKT1, HER2, and ERK2-were identified through network pharmacology and protein-protein interaction analysis. A panel of natural compounds, including ophiobolin A, deoxyelephantopin, eupalmerin acetate, curcumin, andrographolide, and syringolin A, was assessed for their inhibitory potential, benchmarking their activity against reference chemotherapeutics. Covalent docking and covalent molecular dynamics (CMD) were performed for 30 ligand-protein complexes to evaluate the binding affinities of the studied compounds. Against EGFR, curcumin displayed a competitive docking score of - 9.458 kcal/mol and ΔG<sub>bind</sub> of - 23.00 kcal/mol, closely matching the performance of afatinib (- 10.134 kcal/mol and - 24.28 kcal/mol, respectively).

This study further explored the effect of KPL sensitizing ABT-199 on liver cancer cell apoptosis and its potential mechanisms. The inhibitory effects of KPL and ABT-199, both individually and in combination, on the proliferation of HepG2, Huh7, and HCCLM3 cells were evaluated.

The typical approach involves surgery and chemotherapy, which due to problems such as drug resistance, encourage researchers to use new methods such as nanotechnology. The current study introduces a novel strategy: leveraging Curcumin-Gold Nanoshells (Cur-AuNShs) to combat chemotherapy's adverse effects and overcome drug resistance through hyperthermia mediation. Gold-based nanoparticles that absorb laser have shown the potential to target and treat cancer selectively through highly efficient light-to-heat conversion. This experimental study focused on the synthesis of AuNShs and their subsequent conjugation with Cur. The gold shell coverage on the surfaces of silica nanoparticles was examined using UV-VIS spectroscopy and transmission electron microscopy (TEM). Dynamic light scattering (DLS) and Zeta potential analysis were employed to evaluate the stability of particle size and surface charge. Human ovarian carcinoma cell lines (SKOV-3) were treated with a combination of Cur (15 μM) and AuNShs (75 μM), under the activation of near-infrared (NIR) laser irradiation at a power of 2.5 W/cm<sup>3</sup> for 5 or 10 min.

In contrast to being very useful for immune defense, dysregulated TLR signaling may be involved in diseases, such as cancer and autoimmune conditions. In cancer, TLRs create an environment that supports tumorigenesis and growth. In addition to this, a class of multifunctional noncoding RNAs (ncRNAs), including miRNAs, lncRNAs, and circRNAs, regulate gene expression without encoding proteins. MiRNAs regulate gene expression in a fine-tuned manner, while lncRNAs and circRNAs do so via diverse mechanisms. Notably, these ncRNAs interact, where lncRNAs and circRNAs function as competing endogenous RNAs and ceRNA, affecting miRNA activity. This interaction has a vital role in cancer pathology, in influencing that of various oncogenes and tumor suppressors in the tumor microenvironment; hence, modulation of ncRNAs could also be a great promising therapeutic approach. In this context, interplay between TLRs and ncRNAs is of paramount importance as they influence various parameters of the tumor microenvironment. TLR signaling works upon the expression of ncRNAs, while ncRNAs work back to regulate TLR signaling in return. An example of this includes miRNA targeting of components of the TLR; lncRNAs induced by TLR signaling possibly would favor tumor progression. Pharmacological interventions directed toward inhibiting these TLR pathways could be the model to halt malignancy by hampering pro-tumor inflammation and boosting immune responses against neoplasms. Hence, the review will highlight the complicated contrast of ncRNAs and TLRs within human cancer.
