Abstract
BACKGROUND The androgen receptor (AR) gene contains a polymorphic trinucleotide (CAG) microsatellite repeat sequence (short or long alleles) that has been associated with fat-free mass in untrained men, which needs to be replicated in athletic cohorts. AIM The purpose of this study was to explore the AR (CAG)n polymorphism in trained individuals. SUBJECTS AND METHODS A total of 61 professional bodybuilders (40 males, 21 females), 73 elite male sprinters and weightlifters and 186 male controls were enrolled in this study. The influence of the AR (CAG)n polymorphism on muscle mass and strength was assessed in bodybuilders, while the frequencies of AR (CAG)n alleles were compared between power athletes and non-athletes. RESULTS The polymorphism was associated with anthropometric and strength measurements in bodybuilders of both genders. Those with ≥21 CAG repeats (i.e. carriers of long alleles) exhibited greater (p < 0.05) body mass index, absolute muscle mass, arm/thigh circumference and upper/lower limb strength compared to those with <21 CAG repeats. Furthermore, carriers of ≥21 CAG repeats were more frequent among power athletes compared to controls (p = 0.0076). CONCLUSIONS Long alleles of the AR (CAG)n polymorphism were associated with greater muscle mass and strength in bodybuilders, and power athlete status.

Revisiting the relationships of 2D:4D with androgen receptor (AR) gene and current testosterone levels: Replication study and meta-analyses. J Neurosci Res 2019; 98:353-370. [PMID: 31359506 DOI: 10.1002/jnr.24502] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2018] [Revised: 07/13/2019] [Accepted: 07/15/2019] [Indexed: 01/07/2023]
Abstract
The relationships of digit ratio (2D:4D) with the length of AR (CAG)n, and testosterone levels from saliva and blood have been extensively debated over the years. This research including three studies further clarifies such controversies. To do so, we re-examined the relationships between the length of AR (CAG)n, 2D:4D, and current testosterone levels, through replication study and meta-analysis for each study. The results indicate: (a) the length of AR (CAG)n is not significantly associated with 2D:4D; (b) current testosterone levels are not significantly associated with the ratio; and (c) the length is not significantly associated with testosterone levels. Thus, AR (CAG)n and current testosterone levels are not significantly related to 2D:4D at individual level.

Abstract
Objective Gastrointestinal cancer is the leading cause of cancer-related death worldwide. The aim of this study was to verify whether the genotype of six short tandem repeat (STR) loci including AR, Bat-25, D5S346, ER1, ER2, and FGA is associated with the risk of gastric cancer (GC) and colorectal cancer (CRC) and to develop a model that allows early diagnosis and prediction of inherited genomic susceptibility to GC and CRC. Methods Alleles of six STR loci were determined using the peripheral blood of six colon cancer patients, five rectal cancer patients, eight GC patients, and 30 healthy controls. Fisher linear discriminant analysis (FDA) was used to establish the discriminant formula to distinguish GC and CRC patients from healthy controls. Leave-one-out cross validation and receiver operating characteristic (ROC) curves were used to validate the accuracy of the formula. The relationship between the STR status and immunohistochemical (IHC) and tumor markers was analyzed using multiple correspondence analysis. Results D5S346 was confirmed as a GC- and CRC-related STR locus. For the first time, we established a discriminant formula on the basis of the six STR loci, which was used to estimate the risk coefficient of suffering from GC and CRC. The model was statistically significant (Wilks’ lambda = 0.471, χ2 = 30.488, df = 13, and p = 0.004). The results of leave-one-out cross validation showed that the sensitivity of the formula was 73.7% and the specificity was 76.7%. The area under the ROC curve (AUC) was 0.926, with a sensitivity of 73.7% and a specificity of 93.3%. The STR status was shown to have a certain relationship with the expression of some IHC markers and the level of some tumor markers. Conclusions The results of this study complement clinical diagnostic criteria and present markers for early prediction of GC and CRC. This approach will aid in improving risk awareness of susceptible individuals and contribute to reducing the incidence of GC and CRC by prevention and early detection.

Interactive effects of testosterone and the androgen receptor CAG repeat length polymorphism on cardiovascular-renal events and mortality in men with diabetes. Diabetes Metab Res Rev 2019; 35:e3081. [PMID: 30261555 DOI: 10.1002/dmrr.3081] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/03/2018] [Revised: 08/31/2018] [Accepted: 09/15/2018] [Indexed: 12/28/2022]
Abstract
AIM Current evidence relating testosterone to cardiovascular disease and mortality is inconclusive. Cellular effects of testosterone are mediated by androgen receptor and longer receptor gene CAG repeat length correlates with reduced transcriptional activity. We investigated the independent and interactive association of total testosterone and CAG repeat length with incident cardiovascular disease (CVD), chronic kidney disease (CKD) and mortality in Chinese men with type 2 diabetes. MATERIALS AND METHODS From March 2008 and February 2009, 474 men with diabetes underwent structured clinical assessment including genotyping for CAG repeat length. Patients were followed for new-onset CVD, CKD defined by estimated glomerular filtration rate <60 mL/min/1.73m2 , and death until 31 May 2015. RESULTS In this cohort (mean age: 58.6 years, disease duration: 15.4 years), CAG repeat number ranged from 11 to 32 with median of 23, and 9.3% had low testosterone. Over follow-up of 5.8 years, 49 (10.3%) men had CVD, 139 (29.3%) had CKD, and 43 (9.1%) died. In multivariate Cox regression adjusted for age, duration of diabetes, and cardiometabolic risk factors, both total testosterone and interaction term of total testosterone × CAG repeat were associated with all-cause death with respective hazard ratios 1.63 (P = 0.002) and 0.98 (P = 0.004). Total testosterone and CAG repeat were not related to incident CVD or CKD. CONCLUSIONS Among men with type 2 diabetes, high total testosterone was associated with increased mortality in the presence of shorter CAG repeat length but decreased mortality in those with long CAG repeats.

Abstract
OBJECTIVES Testosterone (T) has an integral, albeit complex, relationship with social behavior, especially in the domains of aggression and competition. However, examining this relationship in humans is challenging given the often covert and subtle nature of human aggression and status-seeking. The present study aimed to investigate whether T levels and genetic polymorphisms in the AR gene are associated with social behavior assessed via natural language use. METHODS We used unobtrusive, behavioral, real-world ambulatory assessments of men in partnered heterosexual relationships to examine the relationship between plasma T levels, variation in the androgen receptor (AR) gene, and spontaneous, everyday language in three interpersonal contexts: with romantic partners, with co-workers, and with their children. RESULTS Men's T levels were positively correlated with their use of achievement words with their children, and the number of AR CAG trinucleotide repeats was inversely correlated with their use of anger and reward words with their children. T levels were positively correlated with sexual language and with use of swear words in the presence of their partner, but not in the presence of co-workers or children. CONCLUSIONS Together, these results suggest that T may influence social behavior by increasing the frequency of words related to aggression, sexuality, and status, and that it may alter the quality of interactions with an intimate partner by amplifying emotions via swearing.

Abstract
Abstract. During the past decades, insertions and deletions (indels) have become
increasingly popular in animal breeding for understanding the relationship
between genotypes and phenotypes. The androgen receptor (AR) plays the
vital role of a bridge on the function of the androgen and has sexual size
dimorphism. For this reason, the objective of this study was to explore the
novel indel variants within the cattle AR gene and to detect their
effects on growth traits in four breeds of Chinese yellow cattle. Herein, we
first confirmed a novel 24 bp indel (AC_000187.1g.4187270-4187293delAATTTATTGGGAGATTATTGAATT) within the intron of
the cattle AR gene. This is consistent with the results predicted
from the NCBI SNP database. The distribution of the indel genotypes of four
Chinese yellow cattle were significantly different from each other
(P < 0.01). After significant correlation analysis, many remarkable
phenotypic differences among the three genotypes were found (P < 0.05).
In conclusion, a novel 24 bp indel within the AR gene
significantly affected growth traits, suggesting that this indel may be a
useful DNA marker for the elimination or selection of excellent individuals for
cattle breeding.
