Store-Operated Calcium Entry in Cancer Stem Cells
Store-Operated Calcium Entry (SOCE), a major mechanism for Ca2+influx from the extracellular medium into excitable and non-excitable cells, is physiologically triggered by the activation of phospholipase C (PLC) and the production of IP3, which subsequently leads to the release of Ca2+from intracellular stores, mainly the ER, resulting in the activation of store-operated calcium channels in the plasma membrane and a rapid increase in cytosolic Ca2+concentration. SOCE is an extremely complex biological mechanism, with high dependency on the pattern of expression of its components-STIMs, Orai, and TRPC proteins- and its modulators in each cell type. Since the last decades of the 20th century, several studies, both in vivo and in vitro, have reported that an altered expression pattern of the proteins that mediate SOCE leads to unbalanced Ca2+homeostasis, which might contribute to tumor development, poor prognosis, and chemotherapeutic drug resistance.

Intracellular Signalling in Wound Healing
The cells response to injury is initiated by growth factors and cytokines that play a key role in wound restoration, and their biological action is achieved via signal transduction. Growth factors and cytokines play distinct roles through all phases of wound healing. In response to injury, they can trigger several strategic signalling transduction pathways that are mostly activated during embryonic skin development. Extracellular signal-regulated kinases (ERKs) and calcium (Ca2+) are the first intracellular signalling molecules for tissue repair response. These signalling molecules regulate several biological activities including cellular migration, proliferation, contractility, survival and many more related to different transcription factors that are usually induced by several other intracellular signalling pathways. This phenomenon makes it difficult to link a specific signalling response to injury.

Physiological Significance of Esophageal TRPV4 Channel
Transient receptor potential vanilloid 4 (TRPV4) is a non-selective cation channel that is broadly expressed in different human tissues, including the digestive system, where it acts as a molecular sensor and a transducer that regulates a variety of functional activities.

Cellular Protein Trafficking in Low-Temperature Response Pathway
Over the years, although substantial progress has been made in understanding low-temperature response mechanisms in plants, the research is more focused on aerial parts of the plants rather than on the root or whole plant, and more efforts have been made in identifying and testing the major regulators of this pathway preferably in the model organism rather than in crop plants. For the low-temperature stress response mechanism, ICE-CBF regulatory pathway turned out to be the solely established pathway, and historically most of the low-temperature research is focused on this single pathway instead of exploring other alternative regulators.

Current Advanced on Raman Spectroscopy
Nowadys, Raman spectroscopy (RS) has been used in several studies on animal cells. Also, the method is popular among biophysicists and life science researchers. RS allows for the study of living cells in their natural conditions without any damage. RS is a well-known approach used in many of biomedical studies. Since biomolecules are involved, the main obstacle to the use of such methods in life science research is the low signal of Raman scattering. There are a number of modifications of RS that allow Raman scattering to be improved. There are existing approaches to detect Raman signals not only on the surface of human skin, but also inside the vasculature and various organs of patients.

Intestinal Porcine Epithelial Cell Lines
Numerous bioactive plant additives have shown various positive effects in pigs and chickens. The demand for feed additives of natural origin has increased rapidly in recent years to support the health of farm animals and thus minimize the need for antibiotics and other drugs. Although only in vivo experiments can fully represent their effect on the organism, the establishment of reliable in vitro methods is becoming increasingly important in the goal of reducing the use of animals in experiments. The use of cell models requires strict control of the experimental conditions so that reliability and reproducibility can be achieved. In particular, the intestinal porcine epithelial cell line IPEC-J2 represents a promising model for the development of new additives. It offers the possibility to investigate antioxidative, antimicrobial, anti- or pro-proliferative and antiviral effects.

Marginal Zone B-Cell Populations
Marginal zone (MZ) B-cells are innate-like, and possess a polyreactive B-cell receptor (BCR) and several pattern recognition receptors (PRR). They are known to generate low-affinity first-line antibody responses against invading pathogens such as encapsulated bacteria. Unfortunately, deregulations affecting MZ B-cell populations have been reported in the context of Human Immunodeficiency Virus (HIV) and other chronic inflammatory conditions.

Aging and Its Molecular Mechanism
Aging is a continuous process over time that is mainly related to natural alterations in mechanical–biological processes. This phenomenon is due to several factors, including the time and energy of biological processes. Aging can be attributed to biological factors such as oxidative stress, cell longevity, and stem cell senescence.

Transfer RNAs Present in Extracellular Vesicles
Extracellular vesicles (EVs) are small cargo-containing structures with a lipid bilayer but do not have the cellular machinery required to replicate. They have been shown to play a role in cell-to-cell communication, as they can be found to transport biological material including proteins, lipids, ribonucleic acid (RNA), and deoxyribonucleic acid (DNA) between cells, leading to cellular changes within multi-cellular organisms. It is a process that has been conserved through evolution, found both in prokaryotes and eukaryotes.
