The synthesis of some amidrazones as bioisosteric diazaallyl radicals is described starting from the reaction mechanism of the lipoxygenases which postulates the existence of a radical after hydrogen abstraction from the arachidonic acid, N1,N3-diaryl-, N1-aryl-N3-alkyl-benzamidrazones and N1-arylacetamidrazones are strong inhibitors of the soja lipoxygenase.

Solar and indoor withering in the manufacturing process of semi-fermented oolong tea are crucial for aroma formation. While the processes have been established through accumulated experience, the underlying mechanisms remain largely unknown. This study identified pairs of gene and volatile organic compound (VOC) that were significantly correlated and up-regulated during solar withering and the first shaking, including lipoxygenase 8 (LOX8) with 3-hexenyl iso-butyrate, terpene synthase 2 (TPS2) with β-ocimene and linalool, as well as tryptophan synthase β-subunit 2 (TSB2) with indole.

Objective: To investigate the role of PCBP1 in the inhibition of lung adenocarcinoma proliferation by carbon irradiation.
Methods: A549 cells were irradiated with different doses of carbon ions to observe clonal survival and detect changes in cell proliferation. Whole transcriptome sequencing and the Illumina platform were used to analyze the differentially expressed genes in A549 cells after carbon ion irradiation.

This study investigated the mechanisms employed by exogenous dopamine application in alleviating chilling injury in kiwifruits during storage at 1 °C for 120 days. Our results indicated that dopamine treatment at 150 µM alleviated chilling injury in kiwifruits during storage at 1 °C for 120 days. By 150 µM dopamine application, higher SUMO E3 ligase (SIZ1) and target of rapamycin (TOR) genes expression accompanied by lower poly(ADP-Ribose) polymerase 1 (PARP1) and sucrose non-fermenting 1-related kinase 1 (SnRK1) genes expression was associated with higher salicylic acid, ATP, NADPH and proline accumulation in kiwifruits during storage at 1 °C for 120 days.

An inflammatory response is related to different inflammatory mediators generated by immune and endometrial cells. The links between lipopolysaccharide (LPS), cytokines, and leukotrienes (LTs) in endometrial stromal cells remain unclear. This study aimed to examine the influence of LPS, tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-4 and IL-10 on 5-lipooxygenase (5-LO), LTA4 hydrolase (LTAH) and LTC4 synthase (LTCS) mRNA and protein abundances, and LTB4 and cysteinyl (cys)-LTs release including LTC4, by the cultured pig endometrial stromal cells, as well as on cell viability.

Arachidonate 15-lipoxygenase type B (ALOX15B) peroxidises polyunsaturated fatty acids to their corresponding fatty acid hydroperoxides, which are subsequently reduced into hydroxy-fatty acids. A dysregulated abundance of these biological lipid mediators has been reported in the skin and blood of psoriatic compared to healthy individuals. RNAscope and immunohistochemistry revealed increased ALOX15B expression in lesional psoriasis samples.
