Summary: Nutrition has a significant impact on animal fitness and female fecundity. This study found that different essential amino acids have varying effects on egg production in Drosophila melanogaster, with methionine and histidine depletion resulting in a slower decline. TOR signaling was identified as a key regulator of this difference, highlighting the importance of amino acid sensitivity and signaling pathways in determining reproductive outcomes.

Summary: By selecting and imposing restrictions on fruit flies, it was found that adult flies had longer lifespans when their viability was lower, indicating selection for the fittest individuals. However, observing a wild-type strain under different conditions showed that increasing viability did not significantly increase lifespan, suggesting a lack of clear correlation between development and lifespan.

Summary: This article introduces the application of Drosophila melanogaster as a model organism in nutrition research, and provides a detailed description of the methods for phenotyping Drosophila. The practical application of fly phenotyping is demonstrated through a discussion of obese phenotypes in response to high-sugar diet and high-fat diet feeding. It is also found that the diets have impacts on the transcriptome and metabolome of Drosophila, which is important for understanding the underlying molecular mechanisms.

Summary: Restricting protein intake has been repeatedly shown to have beneficial health outcomes, including increased stress tolerance. By studying Drosophila melanogaster, researchers found that transiently restricting a single essential amino acid can protect adult flies against a lethal dose of nicotine. The protection varied depending on the specific amino acid and the duration and intensity of its restriction. By modifying the signaling of two cellular sensors of amino acids, GCN2 and mTORC1, the researchers discovered that GCN2 is necessary for the protective effects while suppressing mTORC1 is sufficient to induce nicotine resistance.

Summary: Reducing overall food intake or altering the proportion of protein relative to other macronutrients can extend lifespan in various organisms. A recent study using Drosophila melanogaster females has identified a single micronutrient that can explain the impact of dietary restriction on lifespan. This finding suggests a potential mechanism involving a trade-off between lifespan and reproduction, depending on the availability of an essential micronutrient - a sterol.

Summary: FK506-sensitive proline rotamase 1 protein (Fpr1p), a homologue of mammalian FKBP12, plays important roles in protein folding and preventing protein aggregation. This study shows that deletion of FPR1 reduces yeast lifespan, and rapamycin treatment does not extend lifespan in the absence of FPR1, indicating that FPR1 is essential for the lifespan extension mechanism of rapamycin in yeast. Additionally, caloric restriction has a different effect on lifespan compared to rapamycin, suggesting that rapamycin affects lifespan through a distinct pathway.

Summary: Small RNAs play a crucial role in coordinating various cellular processes, affecting gene expression, genomic stability, and suppressing mutagenic transposon activity, thus influencing aging, longevity, and sensitivity to stress factors. Proteins of the Argonaute family are essential for the biogenesis and activity of small RNAs, but their role in regulating lifespan and radioresistance is still not well understood. Studies on knockdown of Argonaute genes in different tissues of Drosophila melanogaster show tissue-specific effects on lifespan, survival after irradiation, and retrotransposon levels, providing insights into the associated molecular mechanisms.

Summary: The research showed that R-phycocyanin (R-PC) has anti-aging activity. It was also found that the effectiveness of anti-aging drugs may vary between genders. Therefore, the study aimed to investigate the differential effects and underlying molecular mechanisms of R-PC on aging in male and female drosophila melanogaster. The results showed that R-PC exerted anti-aging effects through different mechanisms in male and female drosophila melanogaster.

It has the ability to resist oxidative stress, and its multiple domains allow it to interact with vital signaling pathways, influencing cell proliferation, apoptosis, and survival. Recent studies have also shown its involvement in the aging process.

The results revealed diversity in these genes across different species and showed that adaptive selection has caused these changes. However, there is a lack of genetic variation in these genes in the Macaca fascicularis and M. mulatta primate models.

Summary: Modifying the proportions of macronutrients in the diet has significant effects on the reproduction and health of animals. In this study, using capillary feeding assays, we explored how adult fruit flies compromise their nutrient intake when limited to single diets. We found that young male and female flies compromised by consuming more food on diets with low protein to carbohydrate ratios. Additionally, female flies showed greater variations in carbohydrate intake compared to males, and mated females consumed more food than virgin females.

Summary: Limiting calories or specific nutrients in a diet has been shown to extend lifespan and reduce reproduction in various species. However, recent findings in fruit flies indicate that supplementing their diet with cholesterol can extend lifespan to the same extent as dietary restriction while sustaining high egg production. The study also suggests that offspring viability is not compromised by the lifespan extension caused by dietary cholesterol supplementation.

Summary: Amino acid disorders (AADs) are rare inherited conditions that affect one in 6500 live births, often leading to neurological decline and death in infants. Dietary modification can be an effective treatment for some AADs like phenylketonuria, but the potential for dietary therapy remains largely unexplored for most AADs. Drosophila is a suitable animal model for nutrigenomic disease modeling due to its conserved amino acid pathways, genetic tractability, and the availability of a customizable synthetic diet.

Summary: Nutrition during developmental stages has long-term effects on adult physiology, disease, and lifespan, known as nutritional programming. This study demonstrated that developmental diets can influence the lifespan of adult Drosophila, particularly through a low-yeast diet. The activity of the Drosophila transcription factor FOXO (dFOXO) was found to be upregulated under developmental low-nutrient conditions, and its knockdown abolished the lifespan-extending effect of the larval low-yeast diet.

Summary: Dietary nutrient composition plays a crucial role in shaping vital fitness traits and behaviors. Fruit flies, like Drosophila melanogaster, experience protein limitation at the level of amino acids. Despite significant differences in gene expression between male and female flies, their amino acid utilization patterns are remarkably conserved.
