    Abstract Polycomb group of proteins play a significant role in chromatin remodelling essential for epigenetic regulation of transcription. Chromobox (CBX) gene family is an important part of canonical polycomb repressive complex 1 (PRC1), belonging to the polycomb group involved in chromatin remodelling. Aberrations in CBX expression are linked to various cancers. To assess their biomarker significance, we performed a pan-cancer analysis of CBX mRNA levels in 18 cancer types. We also performed cancer classification using CBX genes as distinctive features for machine learning model development. Logistic regression (L.R.), support vector machine (SVM), random forest (R.F.), decision tree (D.T.), and XGBoost (XGB) algorithms for model training and classification. The expression of CBX genes was significantly changed in four cancer types, i.e., cholangiocarcinoma (CHOL), colon adenocarcinoma (COAD), lung adenocarcinoma (LUAD), and lung squamous cell carcinoma (LUSC). The fold change (FC) values suggest that CBX2 was significantly upregulated in CHOL (FC = 1.639), COAD (FC = 1.734), and LUSC (FC = 1.506). On the other hand, CBX7 was found downregulated in COAD (FC = -1.209), LUAD (FC = -1.190), and LUSC (FC = -1.214). The performance of machine learning models for classification was excellent. L.R., R.F., SVM, and XGB obtained a prediction accuracy of 100 % for most cancers. However, D.T. performed comparatively poorly in prediction accuracy. The results suggest that CBX expression is significantly altered in all the cancers studied; therefore, they might be treated as potential biomarkers for therapeutic intervention of these cancers.

    Abstract It is known from in vitro studies that macromolecular crowding in the cell effects protein structure, stability and function; but predictive studies are relatively unexplored. There are few reports where the effect of various crowder mixtures has been exploited to discern their combined effect on the structural stability of proteins. These studies are more significant because their effect can mimicked with in vivo conditions, where the environment is heterogeneous. Effects of two crowders, polyethylene glycol (PEG 400 Da), and its monomer ethylene glycol (EG) alone and in mixture on the structural stability of cytochrome

    Abstract Microtubule-associated protein tau is involved in the tubulin binding leading to microtubule stabilization in neuronal cells which is essential for stabilization of neuron cytoskeleton. The regulation of tau activity is accommodated by several kinases which phosphorylate tau protein on specific sites. In pathological conditions, abnormal activity of tau kinases such as glycogen synthase kinase-3 β (GSK3β), cyclin-dependent kinase 5 (CDK5), c-Jun N-terminal kinases (JNKs), extracellular signal-regulated kinase 1 and 2 (ERK1/2) and microtubule affinity regulating kinase (MARK) lead to tau hyperphosphorylation. Hyperphosphorylation of tau protein leads to aggregation of tau into paired helical filaments like structures which are major constituents of neurofibrillary tangles, a hallmark of Alzheimer's disease. In this review, we discuss various tau protein kinases and their association with tau hyperphosphorylation. We also discuss various strategies and the advancements made in the area of Alzheimer's disease drug development by designing effective and specific inhibitors for such kinases using traditional in vitro/in vivo methods and state of the art in silico techniques.

    Abstract Since the emergence of yellow fever in the Americas and the devastating 1918 influenza pandemic, biologists and clinicians have been drawn to human infecting viruses to understand their mechanisms of infection better and develop effective therapeutics against them. However, the complex molecular and cellular processes that these viruses use to infect and multiply in human cells have been a source of great concern for the scientific community since the discovery of the first human infecting virus. Viral disease outbreaks, such as the recent COVID-19 pandemic caused by a novel coronavirus, have claimed millions of lives and caused significant economic damage worldwide. In this study, we investigated the mechanisms of host-virus interaction and the molecular machinery involved in the pathogenesis of some common human viruses. We also performed a phylogenetic analysis of viral proteins involved in host-virus interaction to understand the changes in the sequence organization of these proteins during evolution for various strains of viruses to gain insights into the viral origin's evolutionary perspectives.
