Verma P, Pal H, Mohanty B. Neurotensin receptor-1 antagonist SR48692 modulation of high-fat diet induced reproductive impairment in male mice. Reprod Toxicol 2024; 123:108498. [PMID: 37952698 DOI: 10.1016/j.reprotox.2023.108498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2023] [Revised: 10/21/2023] [Accepted: 11/08/2023] [Indexed: 11/14/2023]
Abstract
Neurotensin (NTS), a tridecapeptide of the gastrointestinal tract, has been implicated in the facilitation of lipid absorption on ingestion of a high-fat diet (HFD) especially via NTS receptors, NTSR1, NTSR2, and NTSR3, to cause lipid metabolic dysregulation and imbalance of the oxidant-antioxidant system. Oxidative stress induced a negative impact on reproductive function, affecting the reproductive organ and related reproductive hormones. The present study elucidated the efficacy of NTSR1 antagonist SR48692 in the modulation of HFD-induced reproductive impairment in male mice. Swiss albino mice (male, 23 ± 2 g) were maintained (6/group) for eight weeks; Group-I chow diet (CD), Group-II HFD, Group-III (HFD+SR48692L), Group-IV (HFD+SR48692H), Group-V (CD+SR48692L) and Group-VI (CD+SR48692H). SR48692 low (100 µg/kg b.w./SR48692L) and high-dose (400 µg/kg b.w./SR48692H) were given intraperitoneally for the last four weeks. Treatment with low-dose (SR48692L) to HFD-fed mice showed some efficacy in mitigating lipid dysregulation, oxidative stress, and reproductive impairment as evidenced by decreased triglycerides, total cholesterol, low-density lipoprotein cholesterol, leptin, and increased high-density lipoprotein cholesterol, increased antioxidant defense enzymes, reduction of histopathological scores in testis and increase in plasma level of LH, FSH and testosterone compared to that of HFD, but not up to CD. With the high-dose of antagonist (SR48692H) showed more adverse effects even from that of HFD. Treatment of both doses of SR48692 to CD-fed mice these effects become more extended. Less effectiveness of NTSR1 antagonist with the doses tried (low and high) in normalizing the lipid dysregulation and reproductive impairments might be due to the persistence of NTSR2/NTSR3-mediated lipid absorption.

Abstract
The antipsychotic drug, olanzapine, is prescribed for postpartum psychosis. Possible adverse effects on fertility of offspring are unclear. We investigated the effects of administering olanzapine via lactation on testicular development and endocrine function of prepuberal male rats. Olanzapine was administered to mothers at 2.5, 5 or 10 mg/kg. We found in male offspring increased body weight, decreased gonadosomatic index, testicular weight and epididymal weight. The volume of seminiferous tubules, seminiferous epithelium, Leydig cells, intertubule tissue and lymphatic space was reduced in rat pups exposed to olanzapine. Tubule diameter and length, seminiferous epithelium height, Leydig cell size and nuclear diameter also were reduced. Testosterone levels were reduced in the groups exposed to olanzapine, while prolactin levels were increased. We observed histopathology in testes of animals whose mothers had been treated with 2.5 mg/kg olanzapine; more severe pathology was observed in offspring whose mothers were administered higher doses. Administration of olanzapine to mothers during lactation produced testicular and endocrine pathology in prepuberal rats in a dose-dependent manner.

Abstract
Lipopolysaccharide (LPS), a toxic component of the cell wall of Gram-negative bacteria, is a potent immune stressor. LPS-induced inflammation of the gut-liver axis is well demonstrated. Neurotensin (NTS), a tri-decapeptide present in the gastrointestinal tract, has anti-inflammatory, anti-oxidative, and growth-promoting properties. This study elucidated the efficacy of PD149163, the type I NTS receptor agonist (NTS1) in the modulation of LPS-induced inflammation of the gut-liver axis of mice. Young-adult female mice (Age: 8 weeks; BW: 25 ± 2.5 g) were maintained in six groups (6/group); Group I as control and Group II, III & IV were exposed to LPS (1 mg/kg BW/Day; i.p.) for five days. LPS pre-exposed Group III and Group IV mice were treated with NTS1 agonist PD149163 (100 μg/kg BW i.p.) and antagonist SR48692 (0.5 mg/kg BW i.p.) respectively for 28 days. Group V and Group VI mice were exposed to only PD149163 and only SR48692 respectively with the doses as mentioned above for 28 days. Group I and LPS-exposed Group II mice were also maintained four weeks without further treatment. Histopathology revealed LPS-induced inflammation of the gut and liver. Significant elevation of plasma TNF-α and IL-6 and serum ALT and AST reflected as biomarkers of inflammation. Oxidative stress on both organs was distinct from decreased glutathione reductase and increased lipid peroxidation. PD149163 but not SR48692 ameliorated LPS-induced inflammation in both gut and liver counteracting inflammatory responses and oxidative stress. The use of NTS agonists including PD149163 could be exploited for therapeutic intervention of inflammatory diseases including that of the gut-liver axis.

Gupta P, Mohanty B. Atypical antipsychotic drug modulates early life infection induced impairment of hypothalamic-pituitary-adrenal axis: An age related study in mice. Eur J Pharmacol 2020; 872:172978. [PMID: 32014487 DOI: 10.1016/j.ejphar.2020.172978] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 01/24/2020] [Accepted: 01/30/2020] [Indexed: 01/13/2023]
Abstract
Evidences from human and animal studies indicate that exposure to infection during early life act as a stressor to impair the hypothalamic-pituitary-adrenal (HPA) axis and may be one of the contributing factors of mental illness of later life. Several atypical antipsychotic drugs (AAPDs) proved to be effective in alleviating psychiatric illness through normalization of HPA axis. However, AAPD are least tried to evaluate their efficacy in modulation of HPA axis impaired under infection. The present study elucidated that the treatment with AAPD paliperidone (PAL: 0.025 mg/kg/bw and 0.05 mg/kg/bw) during periadolescence period (postnatal day 35- postnatal day 56) dose-dependently normalized the HPA axis of the female mice who were gestationally (gestational day 15 and 17) exposed to bacterial endotoxin lipopolysaccharide (LPS: 800 μg/kg/bw; intraperitoneally). The effectiveness of PAL treatment in counteracting the LPS induced hyperactivity of HPA axis was age-related, better observed at postnatal day 120 than at postnatal day 200. The PAL modulation of HPA axis reflected at different levels: inhibition of hypothalamic CRF expression and reduction in plasma levels of adrenocorticotropin and corticosterone. Histopathological alterations such as hypertrophy and/or hyperplasia in cortical zona fasciculata as well as medullary chromaffin cells of adrenal also normalized on PAL treatment. The comparatively long wash out period after drug treatment (postnatal day 57- postnatal day 200) along with age related hormonal imbalance could be correlated to less effectiveness of PAL on HPA axis at postnatal day 200. PAL modulation of HPA axis might be through maintenance of cytokines and reproductive axis homeostasis.

Abstract
Aims Many patients taking risperidone for the treatment of psychiatric disorders experience substantial body weight gain. Researchers have speculated that risperidone induces obesity by modulating central signals; however, the precise central mechanisms involved remain to be fully elucidated. Methods Twenty‐four C57BL/6J mice were divided into four groups: a control group; a risperidone‐treated group; a lorcaserin‐treated group; and a combined risperidone + lorcaserin‐treated group. The mice were received the corresponding treatments for 4 weeks, and their brains were collected for in situ hybridization analysis. A subset of C57BL/6J mice was administrated with risperidone or placebo, and brains were collected 60 minutes post‐treatment for determination of c‐fos activity. In addition, brains of NPY‐GFP mice treated with or without risperidone were collected to perform colocalization of NPY and c‐fos, as well as NPY and 5‐HT2c receptor using immunohistochemistry. Results There was significantly elevated c‐fos expression in the hypothalamic arcuate nucleus (Arc) of risperidone‐treated mice. More than 68% c‐fos‐positive neurons were NPY‐expressing neurons. Furthermore, in situ hybridization revealed that Arc NPY mRNA expression was significantly increased in the risperidone‐treated group compared with control group. Moreover, we identified that 95% 5‐HT2c receptors were colocalized with NPY positive neurons, and increased Arc NPY mRNA expression induced by risperidone was markedly reduced by cotreatment with lorcaserin, a specific 5‐HT2c receptor agonist. Conclusion Our findings provide critical insight into the mechanisms underlying antipsychotic‐induced obesity, which may assist the development of therapeutic strategies to address metabolic side effects of risperidone.

The central mechanism of risperidone-induced hyperprolactinemia. Prog Neuropsychopharmacol Biol Psychiatry 2017; 76:134-139.

Abstract
Risperidone is known to increase prolactin secretion in treating mental illness patients. This side-effect is thought to be mediated via central signaling pathway. However, the exact pathway involved between risperidone and hyperprolactinemia are still unknown. Therefore, we have treated mice with risperidone and investigated the central mechanisms. The present study showed that in risperidone treated group, the level of the serum prolactin significantly increased, which was consistent with increased positive prolactin staining in pituitary gland. Elevated c-fos expression was observed in the arcuate hypothalamic nucleus (Arc) where we found 65% c-fos positive neurons co-localised with neuropeptide Y (NPY) in mice treated with risperidone. In addition, the results from in situ hybridization showed that the NPY mRNA in the Arc was significantly increased, whereas the tyrosine hydroxylase (TH) mRNA dramatically decreased compared with control group in the paraventricular hypothalamic nucleus (PVN). These findings revealed that risperidone may mediate the transcriptional regulation of Arc NPY and TH in the PVN. Furthermore, risperidone induced a decreased dopamine synthesis in the PVN and thus reduced the dopamine-induced inhibition of prolactin release, ultimately lead to hyperprolactinemia. Therefore, insights into these neuronal mechanisms open up potential new ways to treat schizophrenia patients in order to ameliorate hyperprolactinemia.
