Sabry R, Williams M, LaMarre J, Favetta LA. Granulosa cells undergo BPA-induced apoptosis in a miR-21-independent manner. Exp Cell Res 2023; 427:113574.

Abstract
Bisphenol A (BPA) is a harmful endocrine disrupting compound that alters not only classical cellular mechanisms but also epigenetic mechanisms. Evidence suggests that BPA-induced changes in microRNA expression can explain, in part, the changes observed at both the molecular and cellular levels. BPA is toxic to granulosa cells (GCs) as it can activate apoptosis, which is known to contribute to increased follicular atresia. miR-21 is a crucial antiapoptotic regulator in GCs, yet the exact function in a BPA toxicity model remains unclear. BPA was found to induce bovine GC apoptosis through the activation of several intrinsic factors. BPA reduced live cells counts, increased late apoptosis/necrosis, increased apoptotic transcripts (BAX, BAD, BCL-2, CASP-9, HSP70), increased the BAX/Bcl-2 ratio and HSP70 at the protein level, and induced caspase-9 activity at 12 h post-exposure. miR-21 inhibition increased early apoptosis and, while it did not influence transcript levels or caspase-9 activity, it did elevate the BAX/Bcl-2 protein ratio and HSP70 in the same manner as BPA. Overall, this study shows that miR-21 plays a molecular role in regulating intrinsic mitochondrial apoptosis; however, miR-21 inhibition did not make the cells more sensitive to BPA. Therefore, apoptosis induced by BPA in bovine GCs is miR-21 independent.

Abstract
The prevalence of adult obesity has risen markedly in recent decades. The endocrine system precisely regulates energy balance, fat abundance and fat deposition. Interestingly, white adipose tissue is an endocrine gland producing adipokines, which regulate whole-body physiology, including energy balance and reproduction. Endocrine disruptor chemicals (EDCs) include natural substances or chemicals that affect the endocrine system by multiple mechanisms and increase the risk of adverse health outcomes. Numerous studies have associated exposure to EDCs with obesity, classifying them as obesogens by their ability to activate different mechanisms, including the differentiation of adipocytes, increasing the storage of triglycerides, or elevating the number of adipocytes. Moreover, in recent years, not only industrial deception and obesity have intensified but also the problem of human infertility. Reproductive functions depend on hormone interactions, the balance of which may be disrupted by various EDCs or obesity. This review gives a brief summary of common EDCs linked with obesity, the mechanisms of their action, and the effect on adipokine levels, reproduction and connected disorders, such as polycystic ovarian syndrome, decrease in sperm motility, preeclampsia, intrauterine growth restriction in females and decrease of sperm motility in males.

Abstract
Folpet, a fungicide, is utilized even in cosmetics and pharmaceuticals. The LD50 of folpet in mammals, birds, and fish is relatively high. Recently, several negative effects of folpet on the respiratory system and cornea have been reported. However, there is no study on the negative effects of folpet on maternal-fetus interactions. In the present study, we used porcine trophectoderm (pTr) cells and porcine luminal epithelial (pLE) cells to investigate the toxic effects of folpet during implantation. Folpet treatment decreased cell proliferation and promoted apoptosis with cell cycle arrest. In addition, the ERK, JNK, and AKT signal pathways were activated by folpet treatment. Folpet treatment induced calcium overload in pTr and pLE cells mediating antimigratory and antiadhesive effects in both cell lines. Co-treatment with calcium chelates decreased the anti-implantation effect of folpet. Overall, our results demonstrated potential reproductive toxicity of folpet in pig.

Serum biochemical profile in buffalo endometritis and impact of treatment with PGF2α and intrauterine gentamicin infusion on postpartum reproductive performance. Trop Anim Health Prod 2020; 52:3697-3706. [PMID: 32986188 DOI: 10.1007/s11250-020-02406-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/14/2020] [Accepted: 09/16/2020] [Indexed: 12/01/2022]
Abstract
Improving reproductive performance of repeat breeder buffalo cows due to clinical endometritis is crucial in overcoming infertility problems in buffalo cows. The aim of the present study was to use PGF2α and/or gentamicin 10% for treatment of endometritis and to determine biochemical parameters in serum that could be used to diagnose endometritis in buffalo cows. A total of 64 anestrous buffalo cows were assigned into one of five treatment groups: group one (n = 9) buffalo cows were physiological normal cows and served as a control group; group 2 buffalo cows had endometritis, but were not treated (n = 10); group 3 buffalo cows had endometritis and were treated with intrauterine delivery of 100 ml of a 10% gentamicin sulfate solution in three times within 1 week (n = 15); group 4 buffalo cows received two I.M. doses of PGF2α (2 ml Estrumate IM) at the time of corpus luteum dominance (n = 15) (treatment 4 does not make sense as you stated that the cows were in anestrus) on the ovary; group 5 buffalo cows received two IM doses of PGF2α at an 11 day interval and the 10% gentamicin solution as described for group 3. Serum samples were collected from control, pre-treated, and post-treated buffalo cows with endometritis to evaluate the diagnostic biochemical parameters. The days to first estrus (DFE), number of services per conception (S/C), days open (DO), and pregnancy rate (Preg) were the measures for determining reproductive performance for the buffalo cows. The buffalo cows treated by gentamicin and PGF2 exhibited their first estrus earlier than cows in the other four groups of cows. The number of days open for control cows was greater (P < 0.05) than for the other groups and the control cows, as were the number of services per conception (P < 0.05) and pregnancy rate (30%: P < 0.05). The receiver operating characteristic (ROC) curve was used to identify biochemical parameters in serum to predict endometritis. Creatine kinase (CK), aspartate aminotransferase (AST), and concentrations of total bilirubin and immunoglobulins in serum were greater (P < 0.05), while serum albumin values were lower (P < 0.05) in serum of buffalo cows with endometritis. From the ROC analyses, CK was the most predictable biomarker for endometritis with an area under the curve of 0.889, sensitivity of 80%, and specificity of 100% (P < 0.001). In conclusion, the use of gentamicin and PGF2 for treatment of endometritis improves the reproductive performance of buffalo cows, and concentrations of CK serve as an aid for diagnosing endometritis.Graphical abstract.

Effects of Bisphenol A on expression of genes related to amino acid transporters, insulin- like growth factor, aquaporin and amino acid release by porcine trophectoderm cells. Reprod Toxicol 2020; 96:241-248.

Abstract
The peri-implantation period of pregnancy is critical for conceptus development, implantation, and signaling for establishment of pregnancy. This study evaluated the effects of bisphenol A (BPA) on proliferation, adhesion, and migration of porcine trophectoderm (pTr2) cells, expression of transporters of arginine and synthesis of amino acids. All concentrations of BPA decreased proliferation and adhesion of pTr2 cells after 96 h compared to the control group. Lower concentrations of BPA (1 × 10-9, 1 × 10-8, 10-7M) increased (P < 0.05), but higher concentrations of BPA (1 × 10-5, 1 × 10-4 M) decreased migration of pTr2 cells. BPA increased expression of SLC7A1 mRNA at lower concentrations (1 × 10-9 to 1 × 10-6M) and SL7A6, another cationic acid transporter, at higher concentrations (1 × 10-5, 1 × 10-4 M). BPA also down-regulated the expression of IGF1 and IGF1 receptor at concentrations of 1 × 10-7 to 1 × 10-4 M compared to the control group. The expression of mRNAs for aquaporins (AQP) 3 and 4 were reduced at all concentrations of BPA, but at lower concentrations of BPA, (1 × 10-9 to 1 × 10-8M) expression of AQP9 mRNA increased and the expression of AQP11 was not affected by BPA (P > 0.05). There was an inhibitory effect of BPA on the release of synthesis of asparagine, threonine, taurine, tryptophan, and ornithine into the culture medium by pTr2 cells. Collectively, BPA adversely affected the expression of transporters for cationic amino acids like arginine, as well as AQPs, IGF1, and IGF1R associated with proliferation, migration, and adhesion of pTr2 cells. Those adverse effects would likely increase pregnancy losses during the peri-implantation period of pregnancy.

The potential protective and therapeutic effects of platelet-rich plasma on ischemia/reperfusion injury following experimental torsion/detorsion of testis in the Albino rat model. Life Sci 2020; 256:117982. [PMID: 32562693 DOI: 10.1016/j.lfs.2020.117982] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Revised: 06/13/2020] [Accepted: 06/14/2020] [Indexed: 12/21/2022]
Abstract
AIMS This study was designed to evaluate the protective and therapeutic efficacy of platelet-rich plasma (PRP) against testicular degeneration and germ cell apoptosis after induced spermatic cord torsion/detorsion (TD) in rats. MATERIALS Forty rats were allocated into 5 groups: 1) control, 2) short torsion/detorsion (STD), 3) long torsion detorsion (LTD), 4) protective (PRP/P) and 5) treatment (PRP/T). Testicular ischemia was induced by twisting the right testis 1080° clockwise for 2.5 h. PRP (10 μl) was injected intra-testicular 5 min before (PRP/P) and 3 h after (PRP/T) detorsion. At the end of the experiment, rats were euthanized at 2, 30, 2, and 30 days for groups 2-5 respectively. Nitric oxide, malondialdehyde, catalase, total antioxidant capacity, reduced glutathione, glutathione-S-transferase, interleukin1 beta, tumor necrosis factor, caspase-3, and B-cell lymphoma 2 expressions were assessed in the testes. Moreover, histological examination was performed. KEY FINDINGS PRP treatment significantly mitigated the torsion-detorsion induced testicular degeneration. Particularly, by improving the state of oxidative stress (NO, P = 0.0001) and antioxidant markers (TAC, GSH, GST, P = 0.0001-0.01) and decreasing the expression of IL-1β, TNF-α and cas 3 and increase the BCL2 fold changes (P = 0.0001). The protective use of PRP is superior to the therapeutic use of PRP in the restoration of the testicular histoarchitecture following TD. SIGNIFICANCE This study illustrates the cyto-protective role of PRP against TD induced testicular cell injury that highlight possible application of PRP as a complementary therapy in different testicular degenerative diseases which might attribute to its ability to ameliorate the oxidative stress and inhibit induced apoptosis.
