Special Issue Information

Dear Colleagues,

Gravity has constantly influenced both physical and biological phenomena throughout all of Earth’s history. The gravitational field played a major role in shaping evolution when life moved from water to land, by influencing natural selection only by limiting the range of acceptable body sizes. Indeed, to counteract gravity, living organisms would need to develop systems to provide cell membrane rigidity, fluid flow regulation, and appropriate structural support and locomotion. However, gravity can influence in a more deep and subtle fashion the way cells and tissues behave and build themselves. Gravity represents an ‘inescapable’ constraint that obliges living beings to adopt only a few configurations among many others. By ‘removing’ the gravitational field, living structures will be free to recover more degrees of freedom, thus acquiring new phenotypes and new functions/properties. Microgravity provides an unexpected opportunity to study how physical cues may successfully drive several biological properties, by interacting with genomic and proteomic cues.

Therefore, it has been argued that the ultimate reason for human space exploration is precisely to enable us to discover ourselves. Controlled studies conducted in microgravity can advance our knowledge, providing amazing insights into the biological mechanism underlying physiology as well as many relevant diseases, such as cancer. Thereby, space-based investigations may serve as a novel paradigm for innovation in basic and applied science.

Potential topics include, but are not limited to:

  • Direct and indirect mechanisms of gravity sensing by cells and tissues;
  • Shape, cytoskeletal, and nucleoskeletal changes in microgravity;
  • Changes in molecular pathways upon microgravity exposure;
  • Cell fate commitment and differentiation in microgravity;
  • How microgravity affects gene expression and gene regulatory circuits, including miRNAs;
  • Experimental models in microgravity: from 2D to 3D cell/organoid cultures.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. 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. Cells is an international peer-reviewed open access semimonthly 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). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Given the growing interest in human exploration of space, it is crucial to identify the effects of space conditions on biological processes. Here, we analyze the transcriptomic response of Caenorhabditis elegans to simulated microgravity and observe the maintained transcriptomic response after returning to ground conditions for four, eight, and twelve days. We show that 75% of the simulated microgravity-induced changes on gene expression persist after returning to ground conditions for four days while most of these changes are reverted after twelve days. Our results from integrative RNA-seq and mass spectrometry analyses suggest that simulated microgravity affects longevity-regulating insulin/IGF-1 and sphingolipid signaling pathways. Finally, we identified 118 genes that are commonly differentially expressed in simulated microgravity- and space-exposed worms. Overall, this work provides insight into the effect of microgravity on biological systems during and after exposure. Full article
