Liraglutide limits the immunogenic cell death-mediated ROS propagation and PI3K/AKT inactivation after doxorubicin-induced gonadotoxicity in rats: Involvement of the canonical Hedgehog trajectory. Int Immunopharmacol 2023; 119:110212.

Abstract
Chemotherapy-accompanied reproductive dysfunction has lately begun to draw the attention of the scientific community owing to the irreversible impact on the patient's quality of life. Here we tended to investigate the potential role of liraglutide (LRG) in modulating the canonical Hedgehog (Hh) signaling in doxorubicin (DXR)-induced gonadotoxicity in rats. Female virgin Wistar rats were divided into 4 groups; control, DXR-treated (25 mg/kg, single i.p. injection), LRG-treated (150 μg/Kg/day, s.c) and itraconazole (ITC; 150 mg/kg/day, p.o)-pretreated group, as the Hh pathway inhibitor. Treatment with LRG potentiated the PI3K/AKT/p-GSK3β cascade and relieved the oxidative burden-induced by the DXR-driven immunogenic cell death (ICD). LRG also upregulated the expression of the Desert hedgehog ligand (DHh) and the patched-1 (PTCH1) receptor and augmented the protein level of Indian hedgehog (IHh) ligand, Gli1 and cyclin-D1 (CD1). Besides, hypertranscription of IHh, DHh, Ptch1, Smo, Gli1/2 and CD1 genes along with a transcriptional recession of Gli3 gene were reported in LRG-treated group. ITC pre-administration partially abrogated this positive effect of LRG, proving the implication of the examined pathway. Microscopically, LRG ameliorated the follicular atresia noticed in the DXR group; effect that was, at least partially, declined by ITC pre-treatment. These findings end to a conclusion that LRG treatment might hinder the DXR-associated reproductive toxicity, resultant from ROS generated by the cells undergoing ICD, and trigger follicular growth and repair by the PI3K/AKT- dependent switching-on of the canonical Hh pathway.

Abstract
Depression during pregnancy adversely affects fetal development. Desvenlafaxine drug is used for the treatment of gestational depression. In light of the well-established role of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) in regulating neurogenesis and neural survival, the role of S100b in nerve cell energetic metabolism, differentiation of neurons and glial cells, an aberrant increase in NGF, BDNF and S100b expression in the fetal brain may contribute to desvenlafaxine cognitive disorders by altering brain development. This study is trying to determine the effect of desvenlafaxine on brain development. Thirty timed pregnant rats (from the 5th to the 20th day) were divided into three groups: control, low dose (5.14 mg/kg/day) and high dose (10.28 mg/kg/day) of desvenlafaxine where all animals received the corresponding doses by gavage. Maternal and fetal brain samples were fixed for histological, immunohistochemical (IHC) study of NGF and evaluated for BDNF and S100b genes expression. Desvenlafaxine induced some of the histopathological alterations in maternal and fetal rat brains. Moreover, IHC analysis of maternal and fetal rat brains showed that groups treated with desvenlafaxine demonstrated a significant increase of NGF protein immunoreactivity compared with that in the controls. Gene expression results revealed upregulation of messenger RNA BDNF and S100B expression. According to developmental changes in the brain, desvenlafaxine affects neonatal growth during pregnancy, which may lead to delay of brain development. So, it is essential to survey the roles of antidepressant drugs on neonatal development during pregnancy.

Abstract
There are four major classes of antifungals with the predominant mechanism of action being targeting of cell wall or cell membrane. As in other drugs, low solubility of these compounds has led to low bioavailability in target tissues. Enhanced drug dosages have effects such as toxicity, drug-drug interactions, and increased drug resistance by fungi. This article reviews the current state-of-the-art of antifungals, structure, mechanism of action, other usages, and toxic side effects. The emergence of nanoformulations to transport and uniformly release cargo at the target site is a boon in antifungal treatment. The article details research that lead to the development of nanoformulations of antifungals and potential advantages and avoidance of the lacunae characterizing conventional drugs. A range of nanoformulations based on liposomes, polymers are in various stages of research and their potential advantages have been brought out. It could be observed that under similar dosages, test models, and duration, nanoformulations provided enhanced activity, reduced toxicity, higher uptake and higher immunostimulatory effects. In most instances, the mechanism of antifungal activity of nanoformulations was similar to that of regular antifungal. There are possibilities of coupling multiple antifungals on the same nano-platform. Increased activity coupled with multiple mechanisms of action presents for nanoformulations a tremendous opportunity to overcome antifungal resistance. In the years to come, robust methods for the preparation of nanoformulations taking into account the repeatability and reproducibility in action, furthering the studies on nanoformulation toxicity and studies of human models are required before extensive use of nanoformulations as a prescribed drug.

Abstract
Early ovary development is considered to be largely hormone independent; yet, there are associations between fetal exposure to endocrine disrupting chemicals and reproductive disorders in women. This can potentially be explained by perturbations to establishment of ovarian endocrine function rather than interference with an already established hormone system. In this study we explore if Hedgehog (HH) signaling, a central pathway for correct ovary development, can be disrupted by exposure to HH-disrupting chemicals, using the antifungal itraconazole as model compound. In the mouse Leydig cell line TM3, used as a proxy for ovarian theca cells, itraconazole exposure had a suppressing effect on genes downstream of HH signaling, such as Gli1. Exposing explanted rat ovaries (gestational day 22 or postnatal day 3) to 30 µM itraconazole for 72 h induced significant suppression of genes in the HH signaling pathway with altered Ihh, Gli1, Ptch1, and Smo expression similar to those previously observed in Ihh/Dhh knock-out mice. Exposing rat dams to 50 mg/kg bw/day in the perinatal period did not induce observable changes in the offspring's ovaries. Overall, our results suggest that HH signal disruptors may affect ovary development with potential long-term consequences for female reproductive health. However, potent HH inhibitors would likely cause severe teratogenic effects at doses lower than those causing ovarian dysgenesis, so the concern with respect to reproductive disorder is for the presence of HH disruptors at low concentration in combination with other ovary or endocrine disrupting compounds.

Abstract
In this review, genotoxic and mutagenic effects of teratogenic chemical agents in both rat and mouse have been reviewed. Of these chemicals, 97 are drugs and 33 are pesticides or belong to other groups. Large literature searches were conducted to determine the effects of chemicals on chromosome abnormalities, sister chromatid exchanges, and micronucleus formation in experimental animals such as rats and mice. In addition, studies that include unscheduled DNA synthesis, DNA adduct formations, and gene mutations, which help to determine the genotoxicity or mutagenicity of chemicals, have been reviewed. It has been estimated that 46.87% of teratogenic drugs and 48.48% of teratogenic pesticides are positive in all tests. So, all of the teratogens involved in this group have genotoxic and mutagenic effects. On the other hand, 36.45% of the drugs and 21.21% of the pesticides have been found to give negative results in at least one test, with the majority of the tests giving positive results. However, only 4.16% of the drugs and 18.18% of the pesticides were determined to give negative results in the majority of the tests. Among tests with major negative results, 12.50% of the teratogenic drugs and 12.12% of the teratogenic pesticides were negative in all conducted tests.

Abstract
Tango® Super is a two-compound fungicide formulation widely employed in grain protection. However, details of Tango® Super effects on cell cultures have not been fully investigated. In this study, bovine lymphocytes were exposed to a concentration range 0.5; 1.5; 3; 6; and 15 μg mL-1 for 4 h to assess the cytotoxicity and genotoxicity of the fungicide. Our experiments revealed that this fungicide treatment reduced cell viability, decreased cell proliferation and provoked apoptotic cell death. Cell cycle analysis showed predominant accumulation of cells in the G0/G1 phase of the cell cycle. The fungicide was able to induce mitochondrial superoxide production accompanied by elevated levels of carbonylated proteins and changes in the lipid membrane composition. The fungicide did not induce micronuclei production, but stimulated both DNA double-strand breaks and the formation of p53 binding protein, which is accumulated during the DNA repair process at the site of double-strand breaks. Based on the obtained data we suppose that the fungicide-induced DNA damage is the result of oxidative stress, which may contribute to higher occurrence of apoptotic cell death. Because ergosterol biosynthesis-inhibiting fungicides are widely used in agriculture to ensure higher crop yields and may cause health impairment of animals and humans, there is a need for further testing to elucidate their potential genotoxic effects using in vivo and/or in vitro systems.

Abstract
BACKGROUND Pregnant women are more susceptible to both vaginal colonization and infection by yeast. One hundred million fungal infected patients have been treated worldwide with itraconazole (Caputo, 2003. METHOD Itraconazole was administrated orally to pregnant rats at doses of 75, 100, or 150 mg/kg during gestational days (GD) 1 to 7 or GD 8 to 14 or GD 14 to 20. The genotoxicity and hepatotoxicity of the antifungal drug itraconazole were assessed during different periods of pregnancy using different methods. RESULTS It was found that itraconazole was a genotoxic drug for both mothers and fetuses. This finding was observed via significant elevation in the estimated comet assay parameters (percentage of fragmented DNA, tail moment, and olive moment), percentage of fragmented DNA measured by diphenylamine assay and mixed smearing and laddering of DNA fragments of liver samples. In addition, itraconazole caused significant elevation in the level of hepatic malondialdehyde and depletion in the catalase activity and glutathione level. Furthermore, itraconazole induced histopathological alterations in the hepatic tissues of both mothers and fetuses. CONCLUSION These findings indicate that itraconazole administration at doses of 75, 100, or 150 mg/kg during pregnancy induced maternal and fetal toxicity that could be induced by the genotoxicity and the oxidative damage.
