The bone marrow is responsible for producing an incredible number of cells daily in order to maintain blood homeostasis through a process called hematopoiesis. Hematopoiesis is a greatly demanding process and one entirely dependent on complex interactions between the hematopoietic stem cell (HSC) and its surrounding microenvironment. Zinc (Zn) is considered an important trace element, playing diverse roles in different tissues and cell types, and zinc finger proteins (ZNF) are proteins that use Zn as a structural cofactor. In this way, the ZNF structure is supported by a Zn that coordinates many possible combinations of cysteine and histidine, with the most common ZNF being of the CysHis (C2H2) type, which forms a family of transcriptional activators that play an important role in different cellular processes such as development, differentiation, and suppression, all of these being essential processes for an adequate hematopoiesis. This review aims to shed light on the relationship between ZNF and the regulation of the hematopoietic tissue. We include works with different designs, including both in vitro and in vivo studies, detailing how ZNF might regulate hematopoiesis.

Hypoxia ischemia (HI) is a leading cause of cerebral palsy and long-term neurological sequelae in infants. Given that mitochondrial dysfunction in neurons contributes to HI brain damage, this study aimed to investigate the regulatory role of miR-9-5p in mitochondrial function following HI injury. Overexpression of miR-9-5p in HI mice or HO-exposed PC12 cells suppressed neuronal injury, associated with increased mitochondrial copy number, normalizing mitochondrial membrane potential, improved nuclear factor-erythroid factor 2-related factor 2 (Nrf2) activation, and downregulation of Keap1.

Hepatocellular carcinoma (HCC) ranks among the most prevalent types of cancer globally. Zinc finger protein 169 (ZNF169) holds significant importance as a transcription factor, yet its precise function in HCC remains to be elucidated. This study aims to examine the clinical importance, biological functions, and molecular pathways associated with ZNF169 in the development of HCC.

Protein phosphatases are critical for regulating cell signaling, cell cycle, and cell fate decisions, and their dysregulation leads to an array of human diseases like cancer. The dual specificity phosphatases (DUSPs) have emerged as important factors driving tumorigenesis and cancer therapy resistance. DUSP12 is a poorly characterized atypical DUSP widely conserved throughout evolution.

Loz1 is a zinc-responsive transcription factor in fission yeast that maintains cellular zinc homeostasis by repressing the expression of genes required for zinc uptake in high zinc conditions. Previous deletion analysis of Loz1 found a region containing two tandem CH zinc-fingers and an upstream "accessory domain" rich in histidine, lysine, and arginine residues to be sufficient for zinc-dependent DNA binding and gene repression. Here we report unexpected biophysical properties of this pair of seemingly classical CH zinc fingers.

MicroRNAs (miRNAs) are highly conserved endogenous non-coding RNAs that play a crucial role in fish immune response by regulating gene expression at the post-transcriptional level. In recent years, the viral diseases caused by infectious hematopoietic necrosis virus (IHNV) have caused significant economic losses in rainbow trout (Oncorhynchus mykiss) aquaculture, whereas the immune regulatory mechanisms of miRNAs involved in rainbow trout resistance to IHNV infection remains largely undefined. In this study, we analyzed the structural characteristics of Oncorhynchus mykiss tumor necrosis factor receptor-associated factor 3 (OmTRAF3) by bioinformatics software and explored the molecular mechanism of miR-203-3p in rainbow trout resistance to IHNV by regulating OmTRAF3 in vivo and in vitro.
