GSK3
Glycogen synthase kinase-3 (GSK3) is a serine/threonine kinase. It was initially identified as a regulator (inhibitor) of glycogen synthesis. It has since been recognized as a multifunctional kinase with a variety of roles both in invertebrates and in vertebrate cells.

Cytokine Storm Syndrome in SARS-CoV-2
Cytokine storm syndrome is a cascade of escalated immune responses disposing the immune system to exhaustion, which might ultimately result in organ failure and fatal respiratory distress. Infection with severe acute respiratory syndrome-coronavirus-2 can result in uncontrolled production of cytokines and eventually the development of cytokine storm syndrome. Mast cells may react to viruses in collaboration with other cells and lung autopsy findings from patients that died from the coronavirus disease that emerged in 2019 (COVID-19) showed accumulation of mast cells in the lungs that was thought to be the cause of pulmonary edema, inflammation, and thrombosis.

TDP-43 Role in Chromatin Remodeling and Transcription
TDP-43 gained momentum in the neurodegeneration field when it was first discovered that almost all amyotrophic lateral sclerosis (ALS) cases and as many as half of frontotemporal dementia (FTD) cases present pathological ubiquitinated inclusions of TDP-43. Its involvement in chromatin silencing and nuclear/cytoplasmic shuttling constitute convergent key findings from several biological screens, and several crucial epigenetic factors appear to be able to modify TDP-43-induced degeneration. TDP-43 activity at the chromatin level and its implication in the regulation of DNA transcription and stability -such as DNA repair and regulation of retrotransposons activity- are further supported by a continuously growing amount of studies.

Lactic Acidosis’ Effect on Energy Metabolism
Lactic acidosis, a hallmark of solid tumour microenvironment, originates from lactate hyperproduction and its co-secretion with protons by cancer cells displaying the Warburg effect. Long considered a side effect of cancer metabolism, lactic acidosis is now known to play a major role in tumour physiology, aggressiveness and treatment efficiency.

Cyclins and Cyclin-Dependent Kinases in Gastric Cancer
Gastric cancer predominantly occurs in adenocarcinoma form and is characterized by uncontrolled growth and metastases of gastric epithelial cells. The growth of gastric cells is regulated by the action of several major cell cycle regulators including Cyclins and Cyclin-dependent kinases (CDKs), which act sequentially to modulate the life cycle of a living cell. It has been reported that inadequate or over-activity of these molecules leads to disturbances in cell cycle dynamics, which consequently results in gastric cancer development.

Effects of Vitamin D on Satellite Cells
Vitamin D is a micronutrient that plays a role in the homeostasis of various body organs, including skeletal muscle. Skeletal muscle growth and regeneration are critically affected by satellite cells, skeletal muscle stem cells. The discovery of vitamin D receptors on satellite cells supports the role of vitamin D in regulating satellite cell function. In vivo studies have shown the effect of vitamin D on skeletal muscle growth in early life, muscle homeostasis in aging, and skeletal muscle regeneration in conditions of muscle injury or chronic disease.

Huntingtin and Other Neurodegeneration-Associated Proteins in Intracellular Pathologies
Neurodegenerative diseases are currently incurable. Numerous experimental data accumulated over the past fifty years have brought us closer to understanding the molecular and cell mechanisms responsible for their development. It is known that the basis of neurodegenerations are proteinopathies, disorders in the structure and function of various proteins that lead to their aggregation and toxic effects on cells. The most common neurodegenerative proteinopathies are amyloidosis (amyloid extracellular plaques in AD), tauopathy (various dementias), α-synucleopathy (Lowy bodies in PD), prionopathy, and TDP-43 proteinopathy (in amyotrophic lateral sclerosis (ALS)).

Protein Structure Prediction
The new advances in deep learning methods have influenced many aspects of scientific research, including the study of the protein system. The prediction of proteins’ 3D structural components is now heavily dependent on machine learning techniques that interpret how protein sequences and their homology govern the inter-residue contacts and structural organization. Especially, methods employing deep neural networks have had a significant impact on recent CASP13 and CASP14 competition. Here, we explore the recent applications of deep learning methods in the protein structure prediction area. We also look at the potential opportunities for deep learning methods to identify unknown protein structures and functions to be discovered and help guide drug–target interactions. Although significant problems still need to be addressed, we expect these techniques in the near future to play crucial roles in protein structural bioinformatics as well as in drug discovery.

Skeletal Muscle Extracellular Matrix
The skeletal muscle provides movement and support to the skeleton, controls body temperature, and regulates the glucose level within the body. This is the core tissue of insulin-mediated glucose uptake via glucose transporter type 4 (GLUT4). The extracellular matrix (ECM) provides a scaffold for cells, controlling biological processes, and providing structural as well as mechanical support to surrounding cells. Disruption of ECM homeostasis results in several pathological conditions. Various ECM components are typically found to be augmented in the skeletal muscle of obese and/or diabetic humans. A better understanding of the importance of skeletal muscle ECM remodeling, integrin signaling, and other factors that regulate insulin activity may help in the development of novel therapeutics for managing diabetes and other metabolic disorders.

Cell Wall Associated Kinase
Cell wall associated kinases (WAKs) are receptor-like protein kinases, found in plant cell walls, that have the capability to transmit signals directly by their cytoplasmic kinase domains. They usually link the plasma membrane to the protein and carbohydrate that composed the cell wall. The receptor-like proteins contain a cytoplasmic serine threonine kinase and a less conserved region; bound to the cell wall and contains a series of epidermal growth factor repeats. WAKs are found in various plants and crops like rice, and maize. In plants genome like Arabidopsis, WAKs, are encoded by five highly similar genes clustered in a 30-kb locus, among them WAK1 & WAK2 are highly distributed. They are primarily involved in regulating plant cell wall functions including cell expansion, bind as well as response to pectins, pathogen response and also protects plants from detrimental effects.
