AI Article Synopsis
- The study focused on how small doses of UV-C radiation can trigger oil synthesis in the diatom Fistulifera solaris.
- A significant increase in oil content was observed within 6 to 24 hours after exposure, with oil volumes rising by 4 to 6 times.
- The research also found that reactive oxygen species (ROS) produced by UV-C played a key role in this oil accumulation process, indicating that UV-C radiation could be an effective method to boost biodiesel production.
Article Abstract
This study investigated the induction of oil synthesis in the oleaginous diatom, Fistulifera solaris, following irradiation with small doses of UV-C. A rapid induction of oil accumulation was confirmed within 6h following UV-C radiation of the diatom cells, with increases in cell oil body volumes after 24h of approximately 4- to 6-fold from the initial volume. Reactive oxygen species (ROS), which can be generated by a UV-C-mediated reaction, were detected in irradiated cells and the correlation between ROS generation and oil accumulation was confirmed. The smallest UV-C intensity required for oil induction in the cells was 10mJ/cm. Based on the ideal biodiesel profile, the most suitable FAME composition was obtained when UV was used to irradiate the cells. The UV-C radiation method is therefore a solution for shortening the oil accumulation period and improving biodiesel productivity.

Background: Nonalcoholic fatty liver disease (NAFLD) has developed as a leading public wellness challenge as a result of changes in dietary patterns. Unfortunately, there is still a lack of effective pharmacotherapy methods for NAFLD. Wang's empirical formula (WSF) has demonstrated considerable clinical efficacy in treating metabolic disorders for years.

The WRINKLED1 (WRI1) transcription factor controls carbon flow in plants through regulating the expression of glycolysis and fatty acid biosynthesis genes. The role of Gossypium hirsutum WRINKLED1 (GhWRI1) in seed-oil accumulation still needs to be explored. Multiple sequence alignment of WRI1 proteins confirmed the presence of two conserved AP2 domains.

Obesity causes fat accumulation, and sarcopenia causes loss of muscle mass and strength; together, they worsen insulin resistance and accelerate muscle decline, creating a harmful cycle. Some supplements, along with physical exercise, could be remedies for sarcopenic obesity (SO). In this review, we aim to draw a comparison between supplements studied in experimental research and those evaluated in clinical studies for SO.

Background: Lipid metabolism is crucial in cancer progression. Lipid droplets (LDs) generated in cancer cells can act as protective mechanisms through alleviating lipotoxicity under stress conditions. We previously developed IC2 from the Chinese medicine icaritin as an inhibitor of stearoyl-CoA desaturase 1 (SCD1).

Objectives: To investigate the therapeutic effect of Exocarpium Citri Grandis formula granules (ECGFG) on fatty liver disease (FLD) in zebrafish and explore the underlying mechanism.
Methods: Nonalcoholic fatty liver disease (NAFLD) and alcoholic fatty liver disease (ALD) models were established in zebrafish larvae at 3 days post fertilization (dpf), in which the treatment efficacy of 16, 32, or 64 μg/mL ECGFG was evaluated by examining zebrafish survival and liver pathologies and using whole-fish oil red O staining and RT-qPCR. The therapeutic mechanism of ECGFG for FLD was investigated using Prussian blue staining, DCFH-DA probe, MDA content detection, RT-qPCR assay and immunohistochemical staining for CAV1.
