CDK Cyclin-dependent kinases (CDKs) are the core effectors of cell cycle progression. CDK activity is regulated through association with their cyclin partners and cyclin-dependent kinase inhibitors (CKIs) as well as by activating and inhibitory phosphorylation events.

Cell fractionation is the process of separating cellular components, such as organelles, proteins, and other macromolecules, from the entire cell.

Animal development from a single-cell zygote to fertile adult requires many rounds of cell division. During each division, cells complete an ordered series of events that collectively form the "cell cycle".

Cannabinoid receptors mediate a number of physiological processes in the brain ranging from appetite regulation, pain, learning, and memory. The major cannabinoid receptors in the brain include CB1 and CB2 receptors, which are G-protein coupled receptors (GPCRs). CB1 interacts with other GPCRs including metabotropic glutamate receptor 1, mGluR1. Endogenous ligands, endocannabinoids, but also exogenously introduced compounds such as tetrahydrocannabinol (THC), activate cannabinoid receptors by promoting the exchange of GDP for GTP, leading to a cascade of signaling pathways that are activated to drive various functions.

Cancer-associated Growth Factor The tumor microenvironment (TME) is composed of a heterogenous mixture of tumor cells, blood vessels, fibroblasts, stromal cells, infiltrating immune cells, and extracellular matrix (ECM) components, whose collective interactions play important roles in tumor development [1]. Cells in the TME secrete a variety of bioactive molecules, including growth factors, cytokines, ECM proteins, and proteases (e.g., MMPs), many of which play critical roles in regulating growth and development of the tumor[2,3].

This article focuses on calcium transport-related proteins and their regulatory mechanisms, with an emphasis on the SERCA family of proteins, the regulatory protein PLN, and the PKA kinase activated by the second messenger cAMP. These three components collectively participate in the fine regulation of intracellular calcium concentration.

The tumor microenvironment (TME) has been shown to play an important role in tumor initiation, development, and metastasis. Numerous factors contribute to the nature of the TME such as the presence of immune cells; T-cells, B-cells, and natural killer (NK) cells, and wider environmental factors, such as extracellular matrix (ECM) stiffness, hypoxia, and interstitial pressure. Amongst all these various factors, fibroblasts have been suggested to play a key role in tumor development.

The modulation of chromatin structure is an essential component in the regulation of transcriptional activation and repression. Modifications can be made by at least two evolutionarily conserved strategies, through the disruption of histone-DNA contacts by ATP-dependent chromatin remodelers, or by histone tail modifications including methylation and acetylation.

ER stress-induced autophagy is the core mechanism by which cells respond to protein homeostasis imbalances.
