Tau Isoforms
Tau was first described as a natively unfolded microtubule-associated protein. In fact, its main function is to promote the assembly of microtubules and stabilize their structure. However, Tau proteins have a variety of other functions, which include maintaining the structural integrity of neurons, contributing to signal transmission between neurons, and axonal transport. Tau also plays a role in regulating myelination, iron homeostasis, and neurogenesis and may also support synaptic plasticity. Other roles attributed to Tau are gene expression regulation, DNA protection, genome stability, microRNA activity, RNA protection, RNA metabolism, and protein synthesis.

Lysosomes in Regulating Metabolism of Hematopoietic Stem Cells
Hematopoietic stem cells (HSCs) have the capacity to renew blood cells at all stages of life and are largely quiescent at a steady state. It is essential to understand the processes that govern quiescence in HSCs to enhance bone marrow transplantation. It is hypothesized that in their quiescent state, HSCs primarily use glycolysis for energy production rather than mitochondrial oxidative phosphorylation (OXPHOS). In addition, the HSC switch from quiescence to activation occurs along a continuous developmental path that is driven by metabolism. Specifying the metabolic regulation pathway of HSC quiescence will provide insights into HSC homeostasis for therapeutic application. Therefore, understanding the metabolic demands of HSCs at a steady state is key to developing innovative hematological therapeutics. Lysosomes are the major degradative organelle in eukaryotic cells. Catabolic, anabolic, and lysosomal function abnormalities are connected to an expanding list of diseases.

Human In Vitro Stem Cell-Derived Models of Epilepsy
The challenges in making animal models of complex human epilepsy phenotypes with varied aetiology highlights the need to develop alternative disease models that can address the limitations of animal models by effectively recapitulating human pathophysiology. The advances in stem cell technology provide an opportunity to use human iPSCs to make disease-in-a-dish models.

Senescent Cells in Cutaneous Wound Healing
Cellular senescence has gained increasing attention in the field of aging research. Senescent cells have been implicated in biological aging processes, tumorigenesis, development, and wound repair amongst other processes and pathologies. Recent findings reveal that senescent cells can both promote and inhibit cutaneous wound healing processes.

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)).

The Anaphase-Promoting Complex/Cyclosome
The anaphase-promoting complex/cyclosome (APC/C) is a complicated cellular component that plays significant roles in regulating the cell cycle process of eukaryotic organisms. The spatiotemporal regulation mechanisms of APC/C in distinct cell cycle transitions are no longer mysterious, and the components of this protein complex are gradually identified and characterized.

Exercise-Boosted Mitochondrial Remodeling in Parkinson’s Disease
Parkinson’s disease (PD) is a movement disorder characterized by the progressive degeneration of dopaminergic neurons resulting in dopamine deficiency in the striatum. Given the estimated escalation in the number of people with PD, interventions aimed at minimizing morbidity and improving quality of life are crucial. Mitochondrial dysfunction and oxidative stress are intrinsic factors related to PD pathogenesis. Accumulating evidence suggests that patients with PD might benefit from various forms of exercise in diverse ways, from general health improvements to disease-specific effects and, potentially, disease-modifying effects.

CSCs is The Main Players in Drug Resistance
Drug resistance is doubtless the main challenge of treatment in cancer patients. It is possible to distinguish two categories of drug resistance: intrinsic resistance and acquired resistance after drug treatment. Compelling evidence highlights that intratumoral heterogeneity is one of the major hurdles involved in intrinsic drug resistance, in which the cancer stem cells (CSCs) represent the main players due to their self-renewal and differentiation abilities.

Phosphatidylinositol Binding Clathrin-Assembly Protein and Alzheimer’s Disease
Genome-wide association studies (GWAS) have identified the PICALM (Phosphatidylinositol binding clathrin-assembly protein) gene as the most significant genetic susceptibility locus after APOE and BIN1. PICALM is a clathrin-adaptor protein that plays a critical role in clathrin-mediated endocytosis and autophagy.

The Molecular Mechanisms of 4-N-[2-(4-Phenoxyphenyl)Ethyl]Quinazoline-4,6-Diamine Activity
Quinazoline derivatives are a large pool of natural and synthetic compounds. The first derivatives of quinazoline were synthesized at the end of the 19th century. one quinazoline derivative (4-N-[2-(4-phenoxyphenyl)ethyl]quinazoline-4,6-diamine)—EVP4593 (also marked as QNZ) was originally synthesized in 2003 as a modulator of the nuclear factor kappa B (NF-κB) signal transduction pathway. Since that time, EVP4593 has been widely used as a blocker of NF-κB signaling (Sigma-Aldrich, cat #481417). Further it has been reported the ability of EVP4593 to affect store-operated calcium channels.
