Special Issue Information

Dear Colleagues,

Gender and biological sex impact the pathogenesis and vulnerability to numerous diseases, including metabolic, neuroendocrine, and neuropsychiatric disorders.

Experimental and clinical evidence has demonstrated that the sex-linked hormonal and environmental background strongly affects functional consequences of gene manipulation and mutation, an aspect that is not often carefully evaluated.

Genetically modified animal models are essential tools to identify the central and peripheral circuits underlying sex differences in metabolism, feeding, and emotional behavior and vulnerability to metabolic disorders and their comorbidities. The phenotype induced in one sex by a genetic manipulation or mutation may be absent, or even be reversed, in the other sex.

This special issue will focus on the new advances in our knowledge on how genetic manipulation in animals as well as human gene mutations can unravel several aspects of metabolic and behavioral functions which are regulated differently in males and females.

The topics that will be covered by this Special Issue comprise but are not limited to sex-related differences of gene alteration (manipulation or mutation) on different metabolic and behavioral functions, including:

  • tissue metabolism
  • peripheral metabolic signals
  • energy balance
  • hormone environment
  • steroid-mediated functions
  • feeding behavior
  • emotional behavior
  • developmental factors
  • gene environment interaction
  • eating disorders
  • metabolic disorders
  • obesity

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metabolites is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs).

Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by deficits in social interaction, impaired communication, and repetitive behaviors. ASD presents a 3:1 ratio of diagnosed boys and girls, raising the question regarding sexual dimorphic mechanisms underlying ASD symptoms, and their molecular basis. Here, we performed in vivo proton magnetic resonance spectroscopy in juvenile male and female Tsc2+/ mice (an established genetic animal model of ASD). Moreover, behavior and ultrasonic vocalizations during social and repetitive tasks were analyzed. We found significant sexual dimorphisms in the levels of metabolites in the hippocampus and prefrontal cortex. Further, we observed that female mutant animals had a differential social behavior and presented an increase in repetitive behavior. Importantly, while mutant females displayed a more simplified communication during social tasks, mutant males exhibited a similar less complex vocal repertoire but during repetitive tasks. These results hint toward sex-dependent alterations in molecular and metabolic pathways, which can lead to the sexual dimorphic behaviors and communication observed in social and repetitive environments.
