Article Abstract

Purpose: This review aims to provide updated information regarding the role of thyroid and leptin hormones and their crosstalk in affecting the male reproductive function in hypothyroid and obesity conditions.

Method: A wide literature search was made using online search engines on published articles using keywords including thyroid hormone, hypothyroidism, leptin hormone, hyperleptinemia, obesity, the relationship between thyroid and leptin hormones and male reproduction, and hypothyroidism, obesity, and male reproduction.

Results: All information pertaining thyroid and leptin hormone effects on male reproduction, hypothyroidism, hyperleptinemia, and obesity effect on male fertility as well as the related molecular mechanisms are obtained.

Conclusion: Thyroid and leptin hormones individually play a significant role in male reproduction. Alterations of these hormones' levels could adversely affect the male reproductive functions. PI3K/AKT signaling was found to be the major signaling pathway involved in mediating the effect of both hormones on male reproduction. Impaired crosstalk between the two hormones may occur in hypothyroidism with obesity which would contribute towards male reproductive dysfunction.

Leptin and thyroid hormones in beta-thalassemia major: A cross-sectional study.

Background: Hypothyroidism and leptin deficiency are two common endocrinopathies in β-thalassemia major patients (β-TM). Changes in leptin levels may lead to changes in thyroid hormone levels in thalassemia patients through suppression of the hypothalamus-pituitary-thyroid axis. Hence, we aimed to evaluate their correlation in β-TM patients.

Introduction: An increase in the intraorbital adipose tissue is the main pathological feature of thyroid-associated ophthalmopathy (TAO). IGF-1R activates PI3K/AKT signaling and accelerates adipogenesis. Pingmu decoction has been demonstrated to promote orbital adipocyte apoptosis; however, less is reported regarding the action mechanism of Danshenol A (DA), a single active ingredient of (Danshen).

Aim: To investigate the mechanistic aspects of inflammation and oxidative stress and their association with thyroid cancer risk.

Methods: We have systematically searched the PubMed and Web of Science databases to perform a comprehensive analysis of the pathogenic mechanisms that link obesity, inflammation, and oxidative stress to thyroid cancer.

Results: Chronic inflammation, a well-known risk factor for cancer progression, is a hallmark characteristic of obesity.
