Abstract
The growth arrest and DNA damage inducible (GADD)45 family includes three small and ubiquitously distributed proteins (GADD45A, GADD45B, and GADD45G) that regulate numerous cellular processes associated with stress signaling and injury response. Here, we provide a comprehensive review of the current literature investigating GADD45A, the first discovered member of the family. We first depict how its levels are regulated by a myriad of genotoxic and non-genotoxic stressors, and through the combined action of intricate transcriptional, posttranscriptional, and even, posttranslational mechanisms. GADD45A is a recognized tumor suppressor and, for this reason, we next summarize its role in cancer, as well as the different mechanisms by which it regulates cell cycle, DNA repair, and apoptosis. Beyond these most well-known actions, GADD45A may also influence catabolic and anabolic pathways in the liver, adipose tissue and skeletal muscle, among others. Not surprisingly, GADD45A may trigger AMP-activated protein kinase activity, a master regulator of metabolism, and is known to act as a transcriptional coregulator of numerous nuclear receptors. GADD45A has also been reported to display a cytoprotective role by regulating inflammation, fibrosis and oxidative stress in several organs and tissues, and is regarded an important contributor for the development of heart failure. Overall data point to that GADD45A may play an important role in metabolic, neurodegenerative and cardiovascular diseases, and also autoimmune-related disorders. Thus, the potential mechanisms by which dysregulation of GADD45A activity may contribute to the progression of these diseases are also reviewed below.

AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 262:106643. [PMID: 37549486 DOI: 10.1016/j.aquatox.2023.106643] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 07/18/2023] [Accepted: 07/27/2023] [Indexed: 08/09/2023]
Abstract
Karenia selliformis can produce toxins such as gymnodimines, and form microalgal blooms causing massive mortality of marine life such as fish and shellfish, and resulting in serious economic losses. However, there are a few of studies on the toxic effects of K. selliformis on marine organisms and the underlying mechanisms, and it is not clear whether the toxins produced by K. selliformis affect fish survival through the food chain. In this study, a food chain was simulated and composed by K. selliformis-brine shrimp-marine medaka to investigate the possibility of K. selliformis toxicity transmission through the food chain, in which fish behavior, histopathology and transcriptomics changes were observed after direct or indirect exposure (through the food chain) of K. selliformis. We found that both direct and indirect exposure of K. selliformis could affect the swimming behavior of medaka, manifested as decreased swimming performance and increased "frozen events". Meanwhile, exposure to K. selliformis caused pathological damage to the intestine and liver tissues of medaka to different degree. The effect of direct exposure to K. selliformis on swimming behavior and damage to fish tissues was more severe. In addition, K. selliformis exposure induced significant changes in the expression of genes related to energy metabolism, metabolic detoxification and immune system in medaka. These results suggest that toxins produced by K. selliformis can be transferred through the food chain, and that K. selliformis can destroy the intestinal integrity of medaka and increase the absorption of toxins, leading to energy metabolism disorders in fish, affecting the metabolic detoxification capacity of the liver. Our finding provides novel insight into the toxicity of K. selliformis to marine fish.

Identification of novel targets in adipose tissue involved in non-alcoholic fatty liver disease progression. FASEB J 2022; 36:e22429.

Abstract
Obesity is a major risk factor for the development of Nonalcoholic fatty liver disease (NAFLD). We hypothesize that a dysfunctional subcutaneous white adipose tissue (scWAT) may lead to an accumulation of ectopic fat in the liver. Our aim was to investigate the molecular mechanisms involved in the causative role of scWAT in NALFD progression. We performed a RNA-sequencing analysis in a discovery cohort (n = 45) to identify genes in scWAT correlated with fatty liver index, a qualitative marker of liver steatosis. We then validated those targets in a second cohort (n = 47) of obese patients who had liver biopsies available. Finally, we obtained scWAT mesenchymal stem cells (MSCs) from 13 obese patients at different stages of NAFLD and established in vitro models of human MSC (hMSC)-derived adipocytes. We observed impaired adipogenesis in hMSC-derived adipocytes as liver steatosis increased, suggesting that an impaired adipogenic capacity is a critical event in the development of NAFLD. Four genes showed a differential expression pattern in both scWAT and hMSC-derived adipocytes, where their expression paralleled steatosis degree: SOCS3, DUSP1, SIK1, and GADD45B. We propose these genes as key players in NAFLD progression. They could eventually constitute potential new targets for future therapies against liver steatosis.

Abstract
The increasing intensity of environmental radiofrequency electromagnetic fields (RF-EMF) has increased public concern about its health effects. Of particular concern are the influences of RF-EMF exposure on the development of the brain. The mechanisms of how RF-EMF acts on the developing brain are not fully understood. Here, based on high-throughput RNA sequencing techniques, we revealed that transcripts related to neurite development were significantly influenced by 1800 MHz RF-EMF exposure during neuronal differentiation. Exposure to RF-EMF remarkably decreased the total length of neurite and the number of branch points in neural stem cells-derived neurons and retinoic acid-induced Neuro-2A cells. The expression of Eph receptors 5 (EPHA5), which is required for neurite outgrowth, was inhibited remarkably after RF-EMF exposure. Enhancing EPHA5 signaling rescued the inhibitory effects of RF-EMF on neurite outgrowth. Besides, we identified that cAMP-response element-binding protein (CREB) and RhoA were critical downstream factors of EPHA5 signaling in mediating the inhibitory effects of RF-EMF on neurite outgrowth. Together, our finding revealed that RF-EMF exposure impaired neurite outgrowth through EPHA5 signaling. This finding explored the effects and key mechanisms of how RF-EMF exposure impaired neurite outgrowth and also provided a new clue to understanding the influences of RF-EMF on brain development.
