“…The Fourier transform infrared (FT‐IR) spectrum of WBP was revealed in Figure 1 and showed the characteristic absorption of the polysaccharides at 1,250 and 1,265 cm –1 (Chen et al., 2015; Miao et al., 2014). WBP exhibited a broad band at 3,410 cm –1 attributed to the peak of O–H stretching vibration bond and an intense band at 2,927 cm –1 corresponded to the peak of C–H stretching vibration bond (Liu et al., 2018). The signals at 1,650 cm –1 and 1,400 cm –1 were derived from the flexural vibration of the –OH bond and the flexural vibration of CH (O–CH 2 ), respectively (Ji et al., 2018).…”

In this study, the structure and pro‐inflammatory activities of water‐soluble wheat bran polysaccharides (WBP) were evaluated. WBP were heteropolysaccharides consisting 60.34% arabinoxylan as the main component and 31.80% mannose residues characterized with the instrumental analyses. The result of cellular experiment displayed that WBP had significant pro‐inflammatory activities by increasing the concentration of nitric oxide (NO) and up‐regulating the inflammatory cytokine expressions of inducible nitric oxide synthase (iNOS), interleukin‐1β (IL‐1β), cyclooxygenase‐2 (COX‐2), and tumor necrosis factor‐α (TNF‐α). WBP mediated macrophages RAW 264.7 pro‐inflammatory response through phosphatidylinositol 3 hydroxykinase/protein kinase B (PI3K/Akt) signaling pathway by significantly promoting Akt and phosphoinositide‐dependent kinase 1 (PDK1) phosphorylations. Meanwhile, the expression of related phosphorylated proteins JNK and ERK1/2 was significantly up‐regulated which suggested that WBP played pro‐inflammatory roles by activating mitogen‐activated protein kinases (MAPKs) signaling pathway. Practical applications In recent years, wheat bran generally has the phenomenon of high yield and low utilization rate. Wheat bran has rich nutritional value and contains a lot of effective biologically active substances. Based on our findings, the water‐soluble polysaccharides extracted from wheat bran have significant effects on regulating immunity and can be utilized as sources of natural immune modulators. The research can develop new functions of wheat bran polysaccharides, and improve processing utilization rate and product added value.

Insect octopamine (OA) receptors are G‐protein coupled receptors (GPCRs) that play essential roles in physiological and behavioural processes. However, there is little information about the function of OA receptors in the aphids' response to stress. From the genome sequence of Rhopalosiphum padi genome sequence, a cosmopolitan cereal pest, we identified six OA receptor genes RpOAMB, RpOctR, RpOctβ1R, RpOctβ2R, RpOctβ3R, RpOctR‐like with two, one, one, four, four, seven exons, respectively. All the OA receptors contain seven transmembrane domains, which were the signature of GPCRs. Our results showed that (1) the contents of OA increased significantly after food starvation, (2) the transcription levels of RpOAMB, RpOctR, RpOctβ2R and RpOctβ3R increased after starvation and were restored after re‐feeding, and (3) the expression levels of these four genes decreased significantly 48 h post‐injection of dsRNA that targeted the respective genes. Knockdown of RpOctR, RpOctβ2R or RpOctβ3R genes significantly increased aphid mortality under 24 h starvation conditions. Mortality of R. padi injected with dsRpOctR or dsRpOctβ2R was significantly higher than control under 48 h starvation treatments. This is the first report on the role of OA receptors in the starvation response of aphids. The current study provides knowledge for a better understanding the physiological roles of insect OA receptors.
