Efficacy of Combination Therapy with Osimertinib and Afatinib in epidermal growth factor receptor-mutant non-small-cell lung cancer Patients
Abstract: Treatment options for patients with non-small-cell lung cancer who have epidermal growth factor receptor mutations are constrained by the emergence of resistance to epidermal growth factor receptor tyrosine kinase inhibitors. Osimertinib or afatinib alone, when tested in a laboratory model, led to the formation of drug-resistant clones harboring epidermal growth factor receptor secondary mutations. However, combining these drugs prevented the emergence of such mutations. In a Phase II clinical trial, …

ALADIN and its Protein Interactions with the Nucleoproteins: An Insilico Analysis
Abstract: The nuclear pore complex (NPCs) are big, protein complexes made up of multiple units that traverse the nuclear envelope (NE), establishing a discerning channel between the cytoplasm and nucleus for the nucleocytoplasmic transport. It has different roles in cellular processes, like cell-cycle progression, control of gene expression, and signal transduction. NPC is a vast and complex structure, compiled from almost 30 proteins, termed nucleoporins. Earlier studies have shown that each …

Biochemical and Biophysical Studies of the Dimerization Process of HIV-RNA Genome
Abstract: HIV infection is correlated with the dimerization of retroviral RNA genomes.Retroviruses are the only known group of viruses that contain two identical (or nearly identical) copies of the RNA genome within the virion. These RNA genomes are non-covalently joined together through a process known as genomic RNA dimerization. Uniquely, the RNA dimerization of the retroviral genome is of crucial importance for efficient retroviral replication. RNA dimerization is the non-covalent process …

Molecular Docking Studies of Wildtype P53 with Damnacanthal and Scopoletin- Phytochemicals Derived from Morinda Citrifolia
Abstract: Cancer is a prominent cause of mortality globally, and it has the potential to impact any region of the body. The tumor suppressor protein P53 plays a significant role in inhibiting tumor growth by regulating DNA repair, inducing cell cycle arrest, promoting senescence, and triggering apoptosis when confronted with genotoxic stress. P53 is found mutated in 50% of cancers where it loses its tumor suppressive properties and gains oncogenic properties …
