Dynamic Cancer Cell Heterogeneity
Though heterogeneity of cancers is recognized and has been much discussed in recent years, the concept often remains overlooked in different routine examinations. Indeed, in clinical or biological articles, reviews, and textbooks, cancers and cancer cells are generally presented as evolving distinct entities rather than as an independent heterogeneous cooperative cell population with its self-oriented biology. There are, therefore, conceptual gaps which can mislead the interpretations/diagnostic and therapeutic approaches.

Induced Nephron Progenitor-like Cells from Human Urine-Derived Cells
Chronic kidney disease (CKD) has emerged as a major public health concern due to its prevalence in 7–12% of the population worldwide, progression to irreversible end-stage renal disease (ESRD), impaired quality of life, associations with high social and financial costs, and high rates of associated morbidity and mortality (an 82% increase in CKD epidemic over the past two decades). The current treatment options for kidney failure involve lifelong dialysis and whole kidney transplantation. Although kidney transplantation undoubtedly offers a better quality of life and life expectancy than dialytic treatment, it is limited by the scarcity of available organs and the huge gap between supply and demand. Furthermore, considering that the average life expectancy of dialysis patients is barely a decade, alternative strategies for preventing or delaying the progression to ESRD are urgently needed. In this context, regenerative medicine strategies employing nephron progenitor cells (NPCs) are a viable approach that is worthy of substantial consideration as a promising cell source for kidney diseases. However, the generation of induced nephron progenitor-like cells (iNPCs) from human somatic cells remains a major challenge.

Caspase Inhibition Improves Electrotransfer Efficiency
Chimeric antigen receptor (CAR) T cell therapy has been approved to treat patients with various B cell-related tumors, including B-cell precursor acute lymphoblastic leukemia (ALL), diffuse large B-cell lymphoma (DLBCL), primary mediastinal B-cell lymphoma (PMBCL), and high-grade B-cell lymphoma. T cell receptor (TCR) knockout is a critical step in producing universal CAR T cells. A promising approach to achieving the knockout is to deliver the CRISPR/Cas9 system into T cells using electrotransfer technology.

Core PCP Proteins in Coordinating Cilia Orientation
As exemplified by the unidirectionally beating cilia of multi-ciliated cells, various epithelial cells polarize not only along the apical-basal axis (inside–outside axis) of epithelial tissues, but also on the plane of epithelial tissues. The latter cell polarity, which is perpendicular to the apical–basal axis, is referred to as planar cell polarity (PCP). Pioneering research using the wings of Drosophila melanogaster identified a group of proteins, core PCP proteins, that orchestrate the establishment of PCP.

Chromosome Territories in Hematological Cancers
Chromosomes are organized in distinct nuclear areas designated as chromosome territories (CT). The structural formation of CT is a consequence of chromatin packaging and organization that ultimately affects cell function. Chromosome positioning can identify structural signatures of genomic organization, especially for diseases where changes in gene expression contribute to a given phenotype.  The term “chromosome territories” was first coined by Theodor Boveri (1909) in the 20th century. However, the idea of a territorial-like organization of chromosomes during interphase appeared as early as 1885, described by Carl Rabl, based on his experiments of cell division using Salamandra maculata. Rabl observed a polarized nuclear position of chromosomes at the beginning and at the end of mitosis, suggesting a preserved chromosome position during cell cycle phases.

Fatty Acid Metabolism Reprogramming in Prostate Cancer
Fatty acids metabolism is rewired significantly in prostate cancer (PCa). Although PCa can be treated with hormone therapy, after prolonged treatment, castration-resistant prostate cancer (CRPC) can develop and can lead to increased mortality. Both whole-body fatty acid (FA) metabolism in PCa patients and cellular FA metabolism play important roles in PCa origination and development. FA metabolism may provide potential candidate targets for the treatment or diagnosis of PCa.

Cancer-Associated Fibroblasts in Pancreatic Ductal Adenocarcinoma
Cancer-associated fibroblasts (CAFs) are key components of the pancreatic tumor microenvironment, maintaining the extracellular matrix, while also being involved in intricate crosstalk with cancer cells and infiltrating immunocytes. Therefore, they are potential targets for developing therapeutic strategies against pancreatic ductal adenocarcinoma (PDAC). However, studies have demonstrated significant heterogeneity in CAFs with respect to their origins, spatial distribution, and functional phenotypes within the PDAC tumor microenvironment. Therefore, it is imperative to understand and delineate this heterogeneity prior to targeting CAFs for PDAC therapy.

Gene Expression Induced by Radiation
According to the Health Physics Society, radiation is defined as energy that travels from a source through space as waves or particles and it can penetrate different materials. The electromagnetic spectrum consists of different wavelengths and frequencies, in which non-ionizing (low frequency) and ionizing (high frequency) radiation are found. Gene expression will be changed due to radiation.

Autophagy in Polyglutamine
Polyglutamine diseases are a group of congenital neurodegenerative diseases categorized with genomic abnormalities in the expansion of CAG triplet repeats in coding regions of specific disease-related genes. Autophagy is defined as the degradation of intracellular components within the lysosome; self-eating.
