Specific macronutrient clusters associated with lower mortality risk: Evidence from NHANES 1999-2018.

Introduction: Accumulating evidence suggest that imbalanced macronutrient composition would increase the risk of chronic diseases. However, previous studies that predominantly focused on individual macronutrients often failed to thoroughly elucidate this complex association.

Objectives: This study aimed to comprehensively analyze the relationship between macronutrient clusters and all-cause mortality.

Silencing LINC01547 induces hepatocellular carcinoma cell apoptosis and metastasis inhibition via the ADAR1/FAK and miR-146b-5p/RAC1 axes.

Growing research indicates that long noncoding RNAs (lncRNAs) are pivotal in the development and advancement of hepatocellular carcinoma (HCC). Our research pinpointed LINC01547 as a notable lncRNA that was significantly downregulated in Hep3B cells treated with bufotalin, whereas it exhibited elevated expression levels in HCC tumor tissues. Further study found that silencing LINC01547 markedly suppressed proliferation, induced apoptosis, and inhibited migration and invasion in Hep3B and HepG2 cells.

First, the mevalonate and sterol biosynthesis pathways were optimized in engineered yeast to increase the metabolic flux toward the biosynthesis of the precursor farnesyl pyrophosphate.

The inverse associations of glycine and histidine in diet with hyperlipidemia and hypertension.

Background: Amino acids are crucial for nutrition and metabolism, regulating metabolic pathways and activities vital to organismal health and stability. Glycine and histidine act as potent antioxidants and anti-inflammatory agents; however, limited knowledge exists regarding the associations between these amino acids and hyperlipidemia and hypertension. The purpose of this study is to investigate the relationship between dietary glycine and histidine, and hyperlipidemia and hypertension.

Bombinin-BO1 induces hepatocellular carcinoma cell-cycle arrest and apoptosis via the HSP90A-Cdc37-CDK1 axis.

Bombinin-BO1 (BO1), a bombinin peptide derived from the skin secretion of , exhibits broad-spectrum antimicrobial activity. To date, the anticancer effect of BO1 remains unclear. This study confirmed cytotoxicity of BO1 on hepatocellular carcinoma cells by inducing S-phase cycle block and apoptosis.

Modulating tumor-associated macrophage polarization by anti-maRCO mAb exerts anti-osteosarcoma effects through regulating osteosarcoma cell proliferation, migration and apoptosis.

Purpose: Osteosarcoma is a primary bone tumor lacking optimal clinical treatment options. Tumor-associated macrophages in the tumor microenvironment are closely associated with tumor development and metastasis. Studies have identified the macrophage receptor with collagenous structure (MARCO) as a specific receptor expressed in macrophages.

Silencing of tropomodulin 1 inhibits acute myeloid leukemia cell proliferation and tumor growth by elevating karyopherin alpha 2-mediated autophagy.

Evidence shows that tropomodulin 1 (TMOD1) is a powerful diagnostic marker in the progression of several cancer types. However, the regulatory mechanism of TMOD1 in tumor progression is still unclear. Here, we showed that TMOD1 was highly expressed in acute myeloid leukemia (AML) specimens, and TMOD1-silencing inhibited cell proliferation by inducing autophagy in AML THP-1 and MOLM-13 cells.

Synergistic role of phenylpropanoid biosynthesis and citrate cycle pathways in heavy metal detoxification through secretion of organic acids.

Excessive heavy metal contaminants in soils have serious ecological and environmental impacts, and affect plant growth and crop yields. Phytoremediation is an environmentally friendly means of lowering heavy metal concentrations in soils. In this study, we analyzed phenotypic and physiological traits, and the transcriptome and metabolome, of sheepgrass (Leymus chinensis) exposed to cadmium (Cd), lead (Pb), or zinc (Zn).

Research on drug treatment and the novel signaling pathway of chronic atrophic gastritis.

Background: Chronic atrophic gastritis (CAG) is a global digestive system disease and one of the important causes of gastric cancer. The incidence of CAG has been increasing yearly worldwide.

Purpose: This article reviews the latest research on the common causes and future therapeutic targets of CAG as well as the pharmacological effects of corresponding clinical drugs.

The microbial biosynthesis of noncanonical terpenoids.

Terpenoids are a class of structurally complex, naturally occurring compounds found predominantly in plant, animal, and microorganism secondary metabolites. Classical terpenoids typically have carbon atoms in multiples of five and follow well-defined carbon skeletons, whereas noncanonical terpenoids deviate from these patterns. These noncanonical terpenoids often result from the methyltransferase-catalyzed methylation modification of substrate units, leading to irregular carbon skeletons.

Farrerol suppresses osteoclast differentiation and postmenopausal osteoporosis by inhibiting the nuclear factor kappa B signaling pathway.

Excessive bone resorption caused by upregulated osteoclast activity is a key factor in osteoporosis pathogenesis. Farrerol is a typical natural flavanone and exhibits various pharmacological actions. However, the role and mechanism of action of farrerol in osteoclast differentiation regulation remain unclear.

Metal-Free 1,3-Boronate Rearrangement to Ketones Driven by Visible Light.

Boronate rearrangements, such as the Matteson and Petasis reactions, are valuable metal-free reactions for the transfer of the carbo group on boron to intramolecular electrophilic sites. However, only highly reactive electrophiles are suitable, and ketones are too inactive for those boronate rearrangements due to the high energy barriers. We disclose here the 1,3-boronate rearrangement to ketones, for which a high energy barrier (44.
