Chen Z, Chen Z, Mo J, Chen Y, Chen L, Deng C. m6A RNA methylation modulates autophagy by targeting Map1lc3b in bisphenol A induced Leydig cell dysfunction. JOURNAL OF HAZARDOUS MATERIALS 2024; 485:136748. [PMID: 39662354 DOI: 10.1016/j.jhazmat.2024.136748] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/22/2024] [Revised: 11/12/2024] [Accepted: 12/01/2024] [Indexed: 12/13/2024]
Abstract
Bisphenol A (BPA) exposure can affect testicular Leydig cells (LCs), potentially causing male infertility. Research suggests that RNA epigenetic response to environmental exposure may impact LCs function and testosterone production, but the role of N6-methyladenosine (m6A) RNA methylation in mediating BPA exposure and its regulatory mechanisms remain unknown. Here, we demonstrate that BPA exposure significantly reduces testosterone biosynthesis and upregulates m6A modification in LCs using both in vivo and in vitro models. The involvement of the m6A "writer" METTL3 and the "eraser" ALKBH5 in regulating LCs m6A levels during BPA exposure was discovered, highlighting their central role. Manipulating these factors to reduce m6A methylation levels demonstrated potential for alleviating BPA-induced damage to LCs. Furthermore, integrated analysis of transcriptomic and MeRIP sequencing data reveals that the upregulation of m6A levels induced by BPA specifically targets the Map1lc3b mRNA, a pivotal regulator of autophagy, thereby exerting suppressive effects on autophagic processes. In conclusion, our findings suggest that targeting m6A RNA methylation could be a potential therapeutic approach to mitigate BPA-induced reproductive toxicity, offering novel insights into the epigenetic regulation of male reproductive health.

Bai SY, Weng W, Wang H, Cui Z, Wu J, Qu Y, Hao Y, Gao P, Zhang Y, Zhou L, Ge X, Guo X, Han J, Yang H. Modulation of Autophagy-Lysosome Axis by African Swine Fever Virus and Its Encoded Protein pEP153R. Curr Issues Mol Biol 2024; 46:11236-11254. [PMID: 39451547 PMCID: PMC11505880 DOI: 10.3390/cimb46100667] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/03/2024] [Revised: 10/01/2024] [Accepted: 10/03/2024] [Indexed: 10/26/2024] Open
Abstract
The autophagy-lysosome axis is an evolutionarily conserved intracellular degradation pathway which constitutes an important component of host innate immunity against microbial infections. Here, we show that African swine fever virus (ASFV), one of most devastating pathogens to the worldwide swine industry, can reshape the autophagy-lysosome axis by recruiting the critical lysosome membrane proteins (LAMP1 and LAMP2) to viral factories while inhibiting autophagic induction in macrophages. The screening of viral membrane proteins led to the identification of several ASFV membrane proteins, exemplified by viral protein pEP153R, that could significantly alter the subcellular localization of LAMP1/2 when expressed alone in transfected cells. Further analysis showed that pEP153R was also a component of viral factories and could induce endoplasmic reticulum (ER) retention of LAMP1/2, leading to the inhibition of the fusion of autophagosomes with lysosomes. Interestingly, the ASFV mutant lacking EP153R could still actively recruit LAMP into viral factories (VFs) and inhibit autophagic flux, indicating the existence of a functional redundancy of other viral proteins in the absence of pEP153R and highlighting the complexity of ASFV replication biology. Taken together, our results reveal novel information about the interplay of ASFV with the autophagy-lysosome axis and a previously unrecognized function of ASFV protein pEP153R in regulating the cellular autophagic process.

Abstract
Oxidative stress triggered by testicular torsion and detorsion in young males could negatively impact future fertility. Using a rat animal model for testicular IRI (tIRI), we aim to study the induction of autophagy (ATG) during testicular ischemia and tIRI and the role of oxidative-stress-induced c-Jun N-terminal Kinase (JNK) as a cytoprotective mechanism. Sixty male Sprague-Dawley rats were divided into five groups: sham, ischemia only, ischemia+SP600125 (a JNK inhibitor), tIRI only, and tIRI+SP600125. The tIRI rats underwent an ischemic injury for 1 h followed by 4 h of reperfusion, while ischemic rats were subjected to 1 h of ischemia only without reperfusion. Testicular-ischemia-induced Beclin 1 and LC3B expression was associated with decreased p62/SQSTM1 expression, increased ATP and alkaline phosphatase (AP) activity, and slightly impaired spermatogenesis. SP600125 treatment improved p62 expression and reduced the levels of Beclin 1 and LC3B but did not affect ATP or AP levels. The tIRI-induced apoptosis lowered the expression of the three ATG proteins and AP activity, activated caspase 3, and caused spermatogenic arrest. SP600125-inhibited JNK during tIRI restored sham levels to all investigated parameters. This study emphasizes the regulatory role of JNK in balancing autophagy and apoptosis during testicular oxidative injuries.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2024; 281:116619. [PMID: 38925031 DOI: 10.1016/j.ecoenv.2024.116619] [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: 03/20/2024] [Revised: 06/09/2024] [Accepted: 06/17/2024] [Indexed: 06/28/2024]
Abstract
This study investigated the effects of compound probiotics (CP) on AFB1-induced cytotoxicity in Sertoli TM4 cells. The L9 (3 × 3) orthogonal test was conducted to determine the optimal CP required for high AFB1 degradation in the artificial gastrointestinal fluid in vitro. The maximal AFB1 degradation rate was 40.55 % (P < 0.05) when the final viable count was 1.0 × 105 CFU/mL for Bacillus subtilis, Lactobacillus casein, and Saccharomyces cerevisiae. The effects of CP and the CP supernatant (CPS) on TM4 cell viability were evaluated to achieve the optimal protective conditions. When CPS4 (corresponding to CP viable counts of 1.0 × 104 CFU/mL) was added to the TM4 cells for 24 h, the cell viability reached 108.86 % (P < 0.05). AFB1 reduced TM4 cell viability in a concentration- and time-dependent manner at an AFB1 concentration ranging from 0 to 1.5 μM after 48-h AFB1 exposure. The optimal AFB1 concentration/times for low- and high damage models were 0.5 and 1.25 μM both for 24 h, which decreased viability to 76.04 % and 65.35 %, respectively. however, CPS4 added to low- and high-damage models increased the cell viability to 97.43 % and 75.12 %, respectively (P < 0.05). Transcriptome sequencing was performed based on the following designed groups: the control, 0.5 μM AFB1, 1.25 μM AFB1, CPS4, and CPS4+0.5 μM AFB1. The Kyoto encyclopedia of genes and genomes (KEGG) pathway enrichment analysis was further performed to identify significantly enriched signaling pathways, which were subsequently verified. It was shown that AFB1 induced apoptosis by blocking the PI3K-AKT-mTOR pathway and upregulating autophagy proteins such as LC3B, Beclin1, and ATG5 while inhibiting autophagic flux. CPS4 promoted AFB1 degradation, activated the p62-NRF2 antioxidant, and inhibited ROS/TRPML1 pathways, thereby reducing ROS production and inflammation and ultimately alleviating AFB1-induced autophagy and apoptosis. These findings supports the potential of probiotics to protect the male reproductive system from toxin damage.

Abstract
Pesticides like atrazine which are frequently present in everyday surroundings, have adverse impacts on human health and may contribute to male infertility. The work aimed to analyze the histological and biochemical effects of atrazine on the testis in adult albino rats and whether co-administration with resveratrol could reverse the effect of atrazine. Forty adult male albino rats in good health participated in this study. They were categorized at random into four groups: the Group Ӏ received water through a gastric tube for two months every day, the Group ӀӀ received resveratrol (20 mg/kg body weight (b.w.)) through a gastric tube for two months every day, the Group ӀӀӀ received atrazine (50 mg/kg bw) through a gastric tube for two months every day, the Group ӀV received concomitant doses of atrazine and resveratrol for two months every day. The testes of the animals were then carefully removed and prepared for biochemical, immunohistochemical, light, and electron microscopic studies. Atrazine exposure led to a significant decrease in serum testosterone hormone level, upregulation of caspase 3 and iNOS mRNA levels, destructed seminiferous tubules with few sperms in their lumens, many collagen fibres accumulation in the tunica albuginea and the interstitium, abnormal morphology of some sperms as well as many vacuolations, and damaged mitochondria in the cytoplasm of many germ cells. Concomitant administration of resveratrol can improve these adverse effects. It was concluded that atrazine exposure is toxic to the testis and impairs male fertility in adult rat and coadministration of resveratrol guards against this toxicity.

Abstract
Basic research on chronic rhinosinusitis (CRS) has advanced significantly in the past two decades, yet a comprehensive understanding of its pathogenic mechanisms remains elusive. Concurrently, there is a growing interest among scientists in exploring the involvement of autophagy in various human diseases, including tumors and inflammatory conditions. While the role of autophagy in asthma has been extensively studied in airway inflammatory diseases, its significance in CRS with or without nasal polyps (NPs), a condition closely linked to asthma pathophysiology, has also garnered attention, albeit with conflicting findings across studies. This review delves into the role of autophagy in CRS, suggesting that modulating autophagy to regulate inflammatory responses could potentially serve as a novel therapeutic target.

Abstract
Autophagy is recognized as a crucial regulatory process, instrumental in the removal of senescent, dysfunctional, and damaged cells. Within the autophagic process, lysosomal digestion plays a critical role in the elimination of impaired organelles, thus preserving fundamental cellular metabolic functions and various biological processes. Mitophagy, a targeted autophagic process that specifically focuses on mitochondria, is essential for sustaining cellular health and energy balance. Therefore, a deep comprehension of the operational mechanisms and implications of autophagy and mitophagy is vital for disease prevention and treatment. In this context, we examine the role of autophagy and mitophagy during hair follicle cycles, closely scrutinizing their potential association with hair loss. We also conduct a thorough review of the regulatory mechanisms behind autophagy and mitophagy, highlighting their interaction with hair follicle stem cells and dermal papilla cells. In conclusion, we investigate the potential of manipulating autophagy and mitophagy pathways to develop innovative therapeutic strategies for hair loss.

The role and function of autophagy through signaling and pathogenetic pathways and lncRNAs in ovarian cancer. Pathol Res Pract 2024; 253:154899.

Abstract
Lysosomal-driven autophagy is a tightly controlled cellular catabolic process that breaks down and recycles broken or superfluous cell parts. It is involved in several illnesses, including cancer, and is essential in preserving cellular homeostasis. Autophagy prevents DNA mutation and cancer development by actively eliminating pro-oxidative mitochondria and protein aggregates from healthy cells. Oncosuppressor and oncogene gene mutations cause dysregulation of autophagy. Increased autophagy may offer cancer cells a pro-survival advantage when oxygen and nutrients are scarce and resistance to chemotherapy and radiation. This finding justifies the use of autophagy inhibitors in addition to anti-neoplastic treatments. Excessive autophagy levels can potentially kill cells. The diagnosis and treatment of ovarian cancer present many difficulties due to its complexity and heterogeneity. Understanding the role of autophagy, a cellular process involved in the breakdown and recycling of cellular components, in ovarian cancer has garnered increasing attention in recent years. Of particular note is the increasing amount of data indicating a close relationship between autophagy and ovarian cancer. Autophagy either promotes or restricts tumor growth in ovarian cancer. Dysregulation of autophagy signaling pathways in ovarian cancers can affect the development, metastasis, and response to tumor treatment. The precise mechanism underlying autophagy concerning ovarian cancer remains unclear, as does the role autophagy plays in ovarian carcinoma. In this review, we tried to encapsulate and evaluate current findings in investigating autophagy in ovarian cancer.
