What is this page?
This page lists the scientific contributions of an author, who either does not have a ResearchGate profile, or has not yet added these contributions to their profile.
It was automatically created by ResearchGate to create a record of this author's body of work. We create such pages to advance our goal of creating and maintaining the most comprehensive scientific repository possible. In doing so, we process publicly available (personal) data relating to the author as a member of the scientific community.
If you're a ResearchGate member, you can follow this page to keep up with this author's work.
If you are this author, and you don't want us to display this page anymore, please let us know.

Lithium is a nutritional trace element that is also used pharmacologically for the management of bipolar and related psychiatric disorders. Recent studies have shown that lithium supplementation can extend health and lifespan in different animal models. Moreover, nutritional lithium uptake from drinking water was repeatedly found to be positively c...
Aging is impacted by interventions across species, often converging on metabolic pathways. Transcription factors regulate longevity yet approaches for their pharmacological modulation to exert geroprotection remain sparse. We show that increased expression of the transcription factor Grainyhead 1 (GRH-1) promotes lifespan and pathogen resistance in...
The ability of pancreatic β-cells to respond to increased demands for insulin during metabolic stress critically depends on proper ribosome homeostasis and function. Excessive and long-lasting stimulation of insulin secretion can elicit endoplasmic reticulum (ER) stress, unfolded protein response, and β-cell apoptosis. Here we show that the diabete...

... Overall the motifs point can be related to cell cycle regulation and are consistent with the interpretation of nTA hi as a marker for chromatin condensation. However, we expect that more information can be extracted, e.g., GRHL1 has also been linked to aging, although in an insulin related manner 22 . Per-cell nTAs are available on Github for further exploration. ...
... Cldn4, Cldn3, and Cldn7 are all upregulated in Beta 3 cells and associated with mature β-cell function [40]. Beta 3 cells upregulate 7 ribosome genes and elevated ribosome biogenesis is associated with increased β-cell apoptosis [41], β-cell replication [23], and mature β-cell function [42], making the functional relevance of overexpression unclear. One gene, Rpl7, is associated with mature β-cell function [43], while Rpl23 protects against apoptosis [44]. ...
