Faculty, Staff and Student Publications

Background: Regulation of mechanistic target of rapamycin complex 1 (mTORC1) plays an important role in aging and nutrition. For example, caloric restriction reduces mTORC1 signaling and extends lifespan, whereas nutrient abundance and obesity increase mTORC1 signaling and reduce lifespan. Skeletal muscle-specific knockout (KO) of DEP domain-containing 5 protein (DEPDC5) results in constitutively active mTORC1 signaling, muscle hypertrophy and an increase in mitochondrial respiratory capacity. The metabolic profile of skeletal muscle, in the setting of hyperactive mTORC1 signaling, is not well known.

Objectives: To determine the metabolomic and lipidomic signature in skeletal muscle from female and male wild-type (WT) and DEPDC5 …

Ensuring Trust In Genomics Research

Faculty, Staff and Student Publications

Reproducibility, transparency, representation, and privacy underpin the trust on genomics research in general and genome-wide association studies (GWAS) in particular. Concerns about these issues can be mitigated by technologies that address privacy protection, quality control, and verifiability of GWAS. However, many of the existing technological solutions have been developed in isolation and may address one aspect of reproducibility, transparency, representation, and privacy of GWAS while unknowingly impacting other aspects. As a consequence, the current patchwork of technological tools only partially and in an overlapping manner address issues with GWAS, sometimes even creating more problems. This paper addresses the progress in …

Theses

Irritable Bowel Syndrome (IBS), Eating Disorders (EDs), and mental stress are understudied in the United Arab Emirates (UAE), especially among university students. The objective of this study is to assess the prevalence of IBS, ED, mental stress, their associations, and the determinants of IBS among United Arab Emirates University (UAEU) students. An observational cross-sectional study was conducted via a 48-item online-survey shared with 14,268 undergraduate/graduate students, registered during academic year 2021-2022 in UAEU. Logistic regression models were performed to examine the predictive factors associated with IBS among UAEU students in total and by ED status. Significance was determined at p< 0.05. The prevalence of IBS was 39%, ED 55.9%, and high mental stress 53.2%, and they co-existed in 15.9% of UAEU students. Students who reported consuming trigger-food were 6 times more likely to have IBS than their counterpart [AOR: 5.859; 95% CI: 3.092–11.102, p< 0.001]. Those who reported intakes of relief-food were 4 times more likely to have IBS compared to their counterpart [AOR: 3.881; 95% CI: 1.669 – 9.022, p=0.002]. Students with family history of IBS (FHIBS) were 2.6 times more likely to have IBS than their counterpart [AOR: 2.572; 95% CI: 1.420–4.660, p= 0.002]. Students with high mental stress were 1.7 times more likely to have IBS than those with low-moderate stress, when adjusted for sex and age [AOR:1.730; 1.058–2.830, p= 0.029). No significant associations existed between IBS and ED, Socioeconomic Characteristics (SEC), lifestyle, dietary, and health-related factors. UAEU students reported high prevalence of IBS, ED and mental stress. A significant relationship was found between IBS and FH-IBS, trigger- and relieving- food. This study confirmed the prevalence of IBS, ED and mental stress. Large cohort studies on university students in the UAE are warranted to establish the relationships among IBS, ED, mental stress and their determinants.
