ATP deficiency triggers ganoderic acids accumulation via fatty acid β-oxidation pathway in Ganoderma lucidum.

Background: Ganoderic acids (GAs), recognized as significant triterpenoid bioactive components in Ganoderma lucidum, exhibit a broad spectrum of pharmacological activities, including immunomodulation, anti-cancer, and anti-aging properties. Despite their significant pharmacological potential, the low yield of GAs from natural sources has emerged as a critical bottleneck hindering their broader application in the pharmaceutical and health care industries. Previous studies have suggested that environmental perturbations can influence energy metabolism, potentially impacting the biosynthesis of bioactive compounds.

Enteric GABAergic neuron-derived γ-aminobutyric acid initiates expression of Igfbp7 to sustain ILC3 homeostasis.

Neuronal signals have emerged as critical factors that regulate group 3 innate lymphoid cell (ILC3) response and tissue homeostasis, but the molecular mechanisms underlying this regulation remain largely elusive. Here, we identified that the enteric GABAergic neuron-derived neurotransmitter γ-aminobutyric acid (GABA) inhibited proliferation and IL-17A production in ILC3s in a manner dependent on the GABA receptors Gabbr1 and Gabbr2. Conditional deletion of Gabbr1 or ablation of GABAergic neurons caused increased IL-17A production and aggravated colitis.

Bidirectional regulation of reactive oxygen species for radiosensitization in nasopharyngeal carcinoma.

Radiotherapy (RT) is the primary treatment modality for nasopharyngeal carcinoma (NPC). However, the tumor microenvironment (TME)-induced radioresistance often compromises its therapeutic efficacy. Herein, we propose an innovative bidirectional radiosensitization strategy for NPC.

Cobweb disease in white button mushroom () is a newly identified disease caused by in China. Currently, there are few highly effective and safe fungicides for controlling this disease in the field. This study assessed the fungicidal effect of prochloraz-manganese chloride complex and seboctylamine acetate against , as well as their ability to control cobweb disease.

IL-18, a therapeutic target for immunotherapy boosting, promotes temozolomide chemoresistance via the PI3K/AKT pathway in glioma.

Interleukin-18, a member of the interleukin - 1 family of cytokines, is upregulated in glioma. However, its effects on glioma remain unclear. This study aimed to explore the role and underlying mechanisms of interleukin-18 expression in glioma.

Framework nucleic acid-based nanoparticles enhance temozolomide sensitivity in glioblastoma.

O-methylguanine DNA methyltransferase (MGMT) is a crucial determinant of temozolomide (TMZ) sensitivity in patients with glioblastoma (GBM). The therapeutic potential of small interfering RNA (siRNA) targeting MGMT to enhance TMZ sensitivity has been hampered by serum nuclease degradation, off-target effects, poor accumulation at tumor sites, and low circulation in blood stream. In this study, we developed a framework nucleic acid-based nanoparticles (FNN), which is constructed from a six-helix DNA bundle, to encapsulate and protect siMGMT for improving TMZ sensitivity in GBM treatment.

Histone H3K9 Lactylation Confers Temozolomide Resistance in Glioblastoma via LUC7L2-Mediated MLH1 Intron Retention.

Temozolomide (TMZ) resistance remains the major obstacle in the treatment of glioblastoma (GBM). Lactylation is a novel post-translational modification that is involved in various tumors. However, whether lactylation plays a role in GBM TMZ resistance remains unclear.

IRP1 mediated ferroptosis reverses temozolomide resistance in glioblastoma via affecting LCN2/FPN1 signaling axis depended on NFKB2.

The prognosis of glioblastoma (GBM) patients is poor, and temozolomide (TMZ) resistance has become an important obstacle to its treatment effect. A growing number of researches have revealed the special characteristics of iron metabolism in GBM chemosensitivity. Iron regulatory protein 1 (IRP1) is an important protein for maintaining intracellular iron homeostasis.

The role of MA modification in the regulation of tumor-related lncRNAs.

-methyladenosine (mA) is the most abundant modification in eukaryotic cells, and it regulates RNA transcription, processing, splicing, degradation, and translation. Long non-coding RNAs (lncRNAs), as transcriptional products with no or limited protein coding ability more than 200 nt in length, play an important role in epigenetic modification, mRNA transcription, splicing, stability, translation, and other biological functions. Extensive studies have shown that both mA modification and lncRNAs are involved in the pathogenesis of various diseases, such as kinds of cancers, heart failure, Alzheimer's disease, periodontitis, human abdominal aortic aneurysm, and obesity.

Design of a tomato classifier based on machine vision.

This paper attempts to design an automated, efficient and intelligent tomato grading method that facilitates the graded selling of the fruit. Based on machine vision, the color images of tomatoes with different morphologies were studied, and the color, shape and size were selected as the key features. On this basis, an automated grading classifier was created based on the surface features of tomatoes, and a grading platform was set up to verify the effect of the classifier.

Hepatoprotective effects of Auricularia cornea var. Li. polysaccharides against the alcoholic liver diseases through different metabolic pathways.

The present work was designed to evaluate the antioxidation and hepatoprotective effects of Auricularia cornea var. Li. polysaccharides (APS) and enzymatic-extractable APS (EAPS) on the acute alcohol-induced alcoholic liver diseases (ALD).

Antioxidant and Hepatoprotective Activities of Polysaccharides from Spent Mushroom Substrates () in Acute Alcohol-Induced Mice.

In order to contribute to the exploitation and utilization of spent mushroom substrates (SMS) of , hot-water-extractable polysaccharides (H-SMPS) and enzymatic-extractable polysaccharides (E-SMPS) were successfully isolated from SMS of . Both H-SMPS and E-SMPS were found to have high reducing power and potential scavenging activities against hydroxyl, DPPH, and superoxide anion radicals. assays showed that the administration of H-SMPS and E-SMPS has potential hepatoprotective effects against alcohol-induced alcoholic liver disease (ALD), possibly brought about by improving liver function, increasing antioxidant status, and reducing lipid peroxidation.
