Spirulina versus metformin for controlling some insulin signaling pathway genes in induced polycystic ovary syndrome rat model. Gene 2024; 921:148524. [PMID: 38735598 DOI: 10.1016/j.gene.2024.148524] [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: 01/25/2024] [Revised: 04/11/2024] [Accepted: 05/01/2024] [Indexed: 05/14/2024]
Abstract
Polycystic ovary syndrome (PCOS) is a prevalent endocrinologic and gynecologic disorder that affects women of reproductive age; besides, insulin resistance (IR) occurs in 50-70 % of PCOS cases. Metformin (Met) is commonly prescribed for IR management; however, it does not affect IR with some gastrointestinal symptoms. Spirulina platensis (SP) is a blue-green alga that may increase insulin sensitivity. Therefore, our study aims to evaluate SP as an alternative treatment to Met for improving glucose homeostasis by assessing the expression of 11 crucial genes involved in the insulin signaling pathway. After induction of the PCOS model using dehydroepiandrosterone (DHEA) (60 mg/kg bwt) for 30 consecutive days, rats were allocated into six groups. Relative liver weight, glutamic pyruvic transaminase (GPT) serum levels, glutamic-oxaloacetic transaminase (GOT), and insulin were determined. Furthermore, the gene expression of Ins1, Irs1, Pik3ca, Prkcz, Foxo1, Srebf1, Ppargc1a, Pklr, Gk, G6pc, and Pepck in the rat's liver tissue was determined using qRT-PCR. Treatment of the PCOS control group with Met or SP revealed a decrease in all these parameters compared with the PCOS model. Additionally, we found a statistically significant difference in the expression of both the Gk and Prkcz genes. To summarize our study results, SP or Met supplementation to PCOS rats had almost the same effect on assessed relative liver weight, GOT, GPT, and insulin levels compared with PCOS control rats. If further studies confirm and detect more impact of SP on IR in PCOS, SP could be used instead of Met since the latter causes many side effects.

Abstract
Physiological processes and behaviors in many mammals are rhythmic. Recently there has been increasing interest in the role of circadian rhythmicity in the control of reproductive function. The circadian rhythm of the pineal hormone melatonin plays a role in synchronizing the reproductive responses of animals to environmental light conditions. There is some evidence that melatonin may have a role in the biological regulation of circadian rhythms and reproduction in humans. Moreover, circadian rhythms and clock genes appear to be involved in optimal reproductive performance. These rhythms are controlled by an endogenous molecular clock within the suprachiasmatic nucleus (SCN) in the hypothalamus, which is entrained by the light/dark cycle. The SCN synchronizes multiple subsidiary oscillators (clock genes) existing in various tissues throughout the body. The basis for maintaining the circadian rhythm is a molecular clock consisting of transcriptional/translational feedback loops. Circadian rhythms and clock genes appear to be involved in optimal reproductive performance. This mini review summarizes the current knowledge regarding the interrelationships between melatonin and the endogenous molecular clocks and their involvement in reproductive physiology (e.g., ovulation) and pathophysiology (e.g., polycystic ovarian syndrome).

A comparison between the effect of trans-anethole and metformin on biochemical parameters of polycystic ovary syndrome in rats. AVICENNA JOURNAL OF PHYTOMEDICINE 2021; 11:484-493. [PMID: 34745920 PMCID: PMC8554281 DOI: 10.22038/ajp.2021.55679.2785] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Revised: 03/09/2021] [Accepted: 03/09/2021] [Indexed: 11/12/2022]
Abstract
Objective: The effect of trans-anethole and metformin on biochemical and hormonal changes of testosterone-induced Polycystic ovary syndrome (PCOS) in rats was investigated. Materials and Methods: Female Wister rats (n=48) were randomly divided into six groups: control; PCOS; PCOS+metformin (300 mg/kg); and PCOS+trans-anethole (20, 40, and 80 mg/kg). PCOS was induced by intraperitoneal injection of testosterone (1 mg/kg/day) for 35 days. After induction of PCOS, trans-anethole and metformin were given orally for 30 days. Finally, blood sugar, insulin, lipid profile, and testosterone and dehydroepiandrosterone (DHEAS) as well as animals’ weight, and water and food intake were determined. Results: In all treated and untreated PCOS groups, serum testosterone levels were significantly increased compared to the control group (p<0.001 for all groups). Treatment of rats with trans-anethole or metformin significantly reduced serum levels of cholesterol, insulin, triglycerides, testosterone and DHEAS (only in PCOS+trans-anethole groups) compared to the PCOS group (p<0.01-p<0.001). Weight gain in the PCOS animals increased significantly compared to the control group (p<0.001), while in the metformin- and trans-anethole (40 and 80)-treated animals it decreased significantly compared to the PCOS group (p<0.01-p<0.001). Conclusion: These results showed that trans-anethole significantly decreased serum levels of insulin, DHEAS and blood lipids. It can be concluded that trans-anethole ameliorates PCOS biochemical and hormonal change in PCOS rats; therefore, it might be suggested as a beneficial remedy for further clinical evaluations in PCOS patients.

A Simplified Iohexol-Based Method to Measure Renal Function in Sheep Models of Renal Disease. BIOLOGY 2020; 9:biology9090259.

Abstract
Sheep are highly adequate models for human renal diseases because of their many similarities in the histology and physiology of kidney and pathogenesis of kidney diseases. However, the lack of a simple method to measure glomerular filtration rate (GFR) limits its use as a model of renal diseases. Hence, we aimed to develop a simple method to measure GFR based on the plasma clearance of iohexol by assessing different pharmacokinetic models: (a) CL2: two-compartment (samples from 15 to 420 min; reference method); (b) CL1: one-compartment (samples from 60 to 420 min); (c) CLlf: CL1 adjusted by a correction formula and (d) SM: simplified CL2 (15 to 300 min). Specific statistics of agreement were used to test the models against CL2. The agreement between CL1 and CL2 was low, but both CL1f and SM showed excellent agreement with CL2, as indicated by a total deviation index of ~5–6%, a concordance correlation of 0.98–0.99% and a coverage probability of 99–100%, respectively. Hence, the SM approach is preferable due to a reduced number of samples and shorter duration of the procedure; two points that improve animal management and welfare.

Abstract
Sheep are commonly used as animal models for human biomedical research, but descriptions of their use for studying the pharmacokinetics of carbapenem antimicrobials, such as ertapenem, are unavailable. Ertapenem is a critical antimicrobial for human infections, and the description of the pharmacokinetics of this drug is of value for research using ovine as models for human diseases, such as urinary tract infections (UTI). There are currently no ovine models for comparative biomedical research of UTI. The objective of this study was to report the pharmacokinetics of ertapenem in sheep after single and multiple dosing. In addition, we explored the effects of an immunomodulatory drug (Zelnate) on the pharmacokinetics of ertapenem in sheep. Eight healthy ewes (weight, 64.4 ± 7.7 kg) were used in an ovine bacterial cystitis model of human cystitis with Pseudomonas aeruginosa. After disease confirmation, each ewe received 1 g of ertapenem intravenously once every 24 h for 5 administrations. Blood was collected intensively (14 samples) during 24 h after the first and last administration. After multiple-dose administration, the volume of distribution was 84.5 mL/kg, clearance was 116.3 mL/h/kg, T1/2(λz) was 1.1 h, and the extraction ratio was 0.02. No significant differences in pharmacokinetic parameters or time points were found between groups treated with the immunostimulant and controls or after the 1st or 5th administration of ertapenem. No accumulation was noted from previous administration. Our ovine pharmacokinetic findings can be used to evaluate therapeutic strategies for ertapenem use (varying drug dosing schedules and combinations with other antimicrobials or immune modulators) in the context of UTI.

Abstract
Polycystic ovary syndrome (PCOS) is a gynecological metabolic and endocrine disorder with uncertain etiology. To understand the etiology of PCOS or the evaluation of various therapeutic agents, different animal models have been introduced. Considering this fact that is difficult to develop an animal model that mimics all aspects of this syndrome, but, similarity of biological, anatomical, and/or biochemical features of animal model to the human PCOS phenotypes can increase its application. This review paper evaluates the recently researched animal models and introduced the best models for different research purposes in PCOS studies. During January 2013 to January 2017, 162 studies were identified which applied various kinds of animal models of PCOS including rodent, primate, ruminant and fish. Between these models, prenatal and pre-pubertal androgen rat models and then prenatal androgen mouse model have been studied in detail than others. The comparison of main features of these models with women PCOS demonstrates higher similarity of these three models to human conditions. Thereafter, letrozole models can be recommended for the investigation of various aspects of PCOS. Interestingly, similarity of PCOS features of post-pubertal insulin and human chorionic gonadotropin rat models with women PCOS were considerable which can make it as a good choice for future investigations.

Abstract
The present study aimed to identify the molecular mechanisms underlying the effects of the fructose-1,6-bisphosphatase 1 (FBP1) signaling pathway within normal follicle development and in hyperandrogenism-induced abnormal follicle growth. To achieve this, murine primary follicles, granulosa cells (GCs) and theca-interstitial cells (TICs) were isolated, cultured in vitro and treated with a high concentration of androgens. A concentration of 1×10−5 mol/l testosterone was considerable to induce hyperandrogenism by MTT assay. All cells were divided into four groups, as follows: Control group, testosterone group, androgen receptor antagonist-flutamide group and flutamide + testosterone group. Flutamide was used in the present study as it blocks the effects of the androgen receptor. The mRNA expression levels of FBP1 were detected using reverse transcription-quantitative polymerase chain reaction. The expression levels and localization of FBP1 were analyzed by western blot analysis and immunofluorescence staining. The experimental results demonstrated that androgen presence stimulated follicle development, whereas excessive testosterone inhibited development. FBP1 was identified as being mainly expressed in follicles; FBP1 protein was significantly expressed in GCs of the 14-day-cultured follicle, as well as in the cytoplasm and nuclei of GCs and TICs in vitro. Testosterone increased FBP1 expression during a specific range of testosterone concentrations. Testosterone increased the expression of FBP1 within GCs. Furthermore, FBP1 and phosphoenolpyruvate carboxykinase 1 (PCK1) mRNA expression was increased in GCs treated with testosterone, whereas forkhead box protein O1 (FOXO1) and peroxisome proliferator-activated receptor γ coactivator-1α mRNA expression was significantly decreased in the testosterone group. In TICs, testosterone and flutamide inhibited the mRNA expression levels of FOXO1 and glucose-6-phosphatase enzyme, and promoted the expression of PCK1. These results suggested that the FBP1 signaling pathway may serve an important role in normal follicle growth and hyperandrogenism-induced abnormal development, which may be associated with abnormal glucose metabolism induced by high concentrations of testosterone.

Abstract
SUMMARY Polycystic ovary syndrome (PCOS) is a heterogeneous endocrine disorder with variable prevalence, affecting about one in every 15 women worldwide. The diagnosis of polycystic ovary syndrome requires at least two of the following criteria: oligoovulation and/or anovulation, clinical and/or biochemical evidence of hyperandrogenism and morphology of polycystic ovaries. Women with PCOS appear to have a higher risk of developing metabolic disorders, hypertension and cardiovascular disorders. The aim of this article was to present a review of the literature by searching the databases Pubmed and Scielo, focusing on publications related to polycystic ovaries, including its pathogenesis, clinical manifestations, diagnosis and therapeutic aspects, as well as its association with cardiovascular and arterial hypertensive disorders.

Abstract
Polycystic ovarian syndrome (PCOS) is a complex condition of ovarian dysfunction and metabolic abnormalities with widely varying clinical manifestations resulting from interference of the genome and the environment through integrative biological mechanisms with the emerging field of epigenetics offering an appealing tool for studying the nature and nurture of the disease. We review the current literature of epigenetic studies on PCOS from disease development to the association analysis of the DNA methylome and to exploratory studies on the molecular mechanisms of disease heterogeneity and comorbidity. Recent data based on profiling of the DNA methylome of PCOS in different tissues provided consistent molecular evidence in support of epidemiological findings on disease comorbidity suggesting a possible autoimmune basis in the pathogenesis of the disease. We show that the field of epigenetics and epigenomics could serve to link molecular regulatory mechanisms with disease development and disease manifestation which could contribute to PCOS prevention and treatment and eventually promote reproductive health in fertile age women. We summarize the up-to-date findings and discuss the implications of various studies and point to new avenues of research on PCOS in the rapidly developing field of epigenetics and epigenomics.
