AI Article Synopsis
- Starvation is a severe natural stressor that can lead to death and forces individuals to prioritize essential biological processes, resulting in energetic trade-offs.
- In a study of Formica exsecta ants, researchers examined how inbreeding affects starvation resistance, particularly looking at gene expression related to stress, metabolism, and immunity.
- Findings showed that while starvation caused significant changes in gene expression across different tissues, inbreeding had minimal impact on the majority of genes analyzed, emphasizing the need for tissue-specific studies in understanding stress responses.
Article Abstract
Starvation is one of the most common and severe stressors in nature. Not only does it lead to death if not alleviated, it also forces the starved individual to allocate resources only to the most essential processes. This creates energetic trade-offs which can lead to many secondary challenges for the individual. These energetic trade-offs could be exacerbated in inbred individuals, which have been suggested to have a less efficient metabolism. Here, we studied the effect of inbreeding on starvation resistance in a natural population of Formica exsecta ants, with a focus on survival and tissue-specific expression of stress, metabolism and immunity-related genes. Starvation led to large tissue-specific changes in gene expression, but inbreeding had little effect on most of the genes studied. Our results illustrate the importance of studying stress responses in different tissues instead of entire organisms.

Transcriptome-scale analysis uncovers conserved residues in the hydrophobic core of the bacterial RNA chaperone Hfq required for small regulatory RNA stability.

The RNA chaperone Hfq plays crucial roles in bacterial gene expression and is a major facilitator of small regulatory RNA (sRNA) action. The toroidal architecture of the Hfq hexamer presents three well-characterized surfaces that allow it to bind sRNAs to stabilize them and engage target transcripts. Hfq-interacting sRNAs are categorized into two classes based on the surfaces they use to bind Hfq.

Purpose: Glucose starvation induces the accumulation of disulfides and F-actin collapse in cells with high expression of SLC7A11, a phenomenon termed disulfidptosis. This study aimed to confirm the existence of disulfidptosis in pancreatic ductal adenocarcinoma (PDAC) and elucidate the role of Cancer Susceptibility 8 (CASC8) in this process.
Methods: The existence of disulfidptosis in PDAC was assessed using flow cytometry and F-actin staining.

In recent decades, many fungi have emerged as major causes of disease in marine mammals. This study reports on the detection of filamentous fungi in the subcutaneous tissue and wound surface on the tail fin of a managed bottlenose dolphin () emaciated due to severe digestive problems. Immunosuppression by chronic diseases and starvation decreased resistance against opportunistic infections.

Preharvest sprouting (PHS) is an unfavorable trait in cereal crops that significantly reduces grain yield and quality. However, the regulatory mechanisms underlying this complex trait are still largely unknown. Here, 276 rice accessions from the 3000 Rice Genomes Project were used to perform a genome-wide association study.
