STAT Activation and Signaling
There is a significant body of evidence that has demonstrated that Signal Transducers and Activators of Transcription (STATs) play a critical role in ovarian cancer progression. The STAT family is comprised of seven distinct proteins, STAT1, STAT2, STAT3, STAT4, STAT5A and 5B, and STAT6. The structure among STAT proteins remains highly conserved, with all STAT proteins encoding a coiled-coil (CC) domain, a DNA-binding (DB) domain, and a SRC homology 2 (SH2) domain.

Ribosomal Gene Loci
Nucleoli form around actively transcribed ribosomal RNA (rRNA) genes (rDNA), and the morphology and location of nucleolus-associated genomic domains (NADs) are linked to the RNA Polymerase I (Pol I) transcription status. The number of rDNA repeats (and the proportion of actively transcribed rRNA genes) is variable between cell types, individuals and disease state. Substantial changes in nucleolar morphology and size accompanied by concomitant changes in the Pol I transcription rate have long been documented during normal cell cycle progression, development and malignant transformation.

Wnt Signaling and Aging of the Gastrointestinal Tract
Wnt signaling plays an essential role in aging of the gastrointestinal tract. Aberration of Wnt signaling seen in aged animals has been shown to affect regenerative capacity and differentiation of intestinal stem cells and promote aging-related deterioration. Similarly, abnormal Wnt signaling was observed in the aged stomach. Specifically, enhanced Wnt signaling in organoids established from the stomachs of aged mice induced the expression of Tbx3, a transcription factor that suppress cellular senescence, and led to augmented cellular proliferation. The enhanced Wnt signaling was due to suppressed Dkk3, a Wnt inhibitor, in aged gastric organoids. With respect to the role of TBX3 in humans, expression of TBX3 in human gastric tissues exhibited positive correlation with patients' age whereas that of DKK3 showed negative correlation with patients' age. In addition, TBX3 expression was also confirmed in gastric cancer tissues but not in normal gastric mucosae. These findings indicated that this DKK3-Wnt-TBX3 pathway may contribute to aging-related gastric carcinogenesis.

HO-1 in Cancer Cell Survival
Heme oxygenases (HOs) act on heme degradation to produce carbon monoxide (CO), free iron, ferritin, and biliverdin. Upregulation of cellular HO-1 levels is signature of oxidative stress for its downstream effects particularly under pro-oxidative status. Subcellular traffics of HO-1 to different organelles constitute a network of interactions compromising a variety of effectors such as pro-oxidants, ROS, mitochondrial enzymes, and nucleic transcription factors. Some of the compartmentalized HO-1 have been demonstrated as functioning in the progression of cancer. Emerging data show the multiple roles of HO-1 in tumorigenesis from pathogenesis to the progression to malignancy, metastasis, and even resistance to therapy. However, the role of HO-1 in tumorigenesis has not been systematically addressed.

Human Cell and Organoid Models
Metabolic (dysfunction) associated fatty liver disease (MAFLD) is one of the most prevalent liver diseases and has no approved therapeutics. The high failure rates witnessed in late-phase MAFLD drug trials reflect the complexity of the disease, and how the disease develops and progresses remains to be fully understood. In vitro, human disease models play a pivotal role in mechanistic studies to unravel novel disease drivers and in drug testing studies to evaluate human-specific responses.

Crosstalk between Apoptosis and Autophagy
Research in biomedical sciences has changed dramatically over the past fifty years. There is no doubt that the discovery of apoptosis and autophagy as two highly synchronized and regulated mechanisms in cellular homeostasis are among the most important discoveries in these decades. Along with the advancement in molecular biology, identifying the genetic players in apoptosis and autophagy has shed light on our understanding of their function in physiological and pathological conditions. Apoptosis and autophagy play essential roles in human health, and their malfunction leads to many diseases, including cancer, neurodegenerative disease, and autoimmune disorders. These mechanisms are highly regulated, and there is complex crosstalk between them.

Cardiovascular Disease and Exercise
Inactivity is a significant risk factor for cardiovascular disease. Exercise may greatly enhance the metabolism and function of the cardiovascular system, lower several risk factors, and prevent the development and treatment of cardiovascular disease while delivering easy, physical, and emotional enjoyment. Exercise regulates the cardiovascular system by reducing oxidative stress and chronic inflammation, regulating cardiovascular insulin sensitivity and the body’s metabolism, promoting stem cell mobilization, strengthening autophagy and myocardial mitochondrial function, and enhancing cardiovascular damage resistance, among other effects.

Cannabis Biomolecule Effects on Cancer Cells
Cancer is a complex family of diseases affecting millions of people worldwide. Gliomas are primary brain tumors that account for ~80% of all malignant brain tumors. Glioblastoma multiforme (GBM) is the most common, invasive, and lethal subtype of glioma. Therapy resistance and intra-GBM tumoral heterogeneity are promoted by subpopulations of glioma stem cells (GSCs). Cannabis sativa produces hundreds of secondary metabolites, such as flavonoids, terpenes, and phytocannabinoids. Cannabis is commonly used to treat various medical conditions, and is used in palliative care of cancer patients. The anti-cancer properties of cannabis compounds include cytotoxic, anti-proliferative, and anti-migratory activities on cancer cells and cancer stem cells. Specific combinations of multiple phytocannabinoids act synergistically against cancer cells and may trigger different anti-cancer signaling pathways. Yet, due to scarcity of clinical trials, there remains no solid basis for the anti-cancer therapeutic potential of cannabis compounds.

Single-Molecule Magnetic Sequencing
Magnetic sequencing is a single-molecule sequencing method in development. A DNA hairpin, containing the sequence of interest, is bound between a magnetic bead and a glass surface. A magnetic field is applied to stretch the hairpin open into single strands, and the hairpin refolds after decreasing of the magnetic field. The hairpin length can be determined by direct imaging of the diffraction rings of the magnetic beads using a simple microscope. The DNA sequences are determined by measuring the changes in the hairpin length following successful hybridization of complementary nucleotides.

TCTP, Cell Biology and Disease
Translationally controlled tumour protein (TCTP) is multifunctional protein expressed in essentially all eukaryotic organisms. It is a cytoprotective protein that is involved in many basic biological processes, such as cellular stress responses, growth and development. Dysregulation of TCTP occurs in various disease processes, and recently the participation of TCTP in several cancer-promoting pathways has been unveiled. Understanding the core biological functions of TCTP, the mechanisms underlying its cellular regulation and its participation in disease processes is essential for the design of effective anti-cancer strategies that may involve targeting of TCTP.  To provide a current overview of the knowledge in this area, we published a review article in Cells, which represents a detailed compilation of the recent progress in this field . Here, we give a brief overview on the core findings that are reported in this article.

Cytoplasmic Functions of cIAP1
Cellular inhibitor of apoptosis 1 (cIAP1) is a cell signaling regulator of the IAP family. Through its E3-ubiquitine ligase activity, it has the ability to activate intracellular signaling pathways, modify signal transduction pathways by changing protein-protein interaction networks, and stop signal transduction by promoting the degradation of critical components of signaling pathways. Thus, cIAP1 appears to be a potent determinant of the response of cells, enabling their rapid adaptation to changing environmental conditions or intra- or extracellular stresses. It is expressed in almost all tissues, found in the cytoplasm, membrane and/or nucleus of cells. cIAP1 regulates innate immunity by controlling signaling pathways mediated by tumor necrosis factor receptor superfamily (TNFRs), some cytokine receptors and pattern recognition-receptors (PRRs). Although less documented, cIAP1 has also been involved in the regulation of cell migration and in the control of transcriptional programs.

Gene Expression Profile in Nucleocytoviricota
Nucleocytoviricota is a large group of double-stranded DNA viruses that fully or partially replicate in the host cytoplasm. Despite marked differences, including virion shape, genome length, and host range, viruses belonging to this phylum have some very conserved characteristics, including the gene expression profile. A temporal pattern of gene expression, also known as a transcription cascade model, is described for these viruses, and comparative transcriptome analysis can be used as a starting point for future transcriptomic investigations.
