Long noncoding RNAs (lncRNA) are emerging as crucial regulators of cell biology. However, the role of lncRNAs in the development and function of polymorphonuclear myeloid-derived suppressor cells (PMN-MDSC) remains unclear. Here, we identified that the lncRNA F730016J06Rik (AK036396) was highly expressed in PMN-MDSCs and that lncRNA AK036396 knockdown promoted the maturation and decreased the suppressive function of PMN-MDSCs. Ficolin B (Fcnb), the expression of which could be assessed as a surrogate for PMN-MDSC development, was the predicted target gene of lncRNA AK036396 based on microarray results. LncRNA AK036396 knockdown attenuated Fcnb protein stability in a manner dependent on the ubiquitin-proteasome system. Moreover, Fcnb inhibition downregulated the suppressive function of PMN-MDSCs. In addition, the expression of human M-ficolin, which is an ortholog of mouse Fcnb, was increased and positively correlated with arginase1 (ARG1) expression. This suppressive molecule is released by MDSCs, and its production is commonly used to represent the suppressive activity of MDSCs in patients with lung cancer, suggesting clinical relevance for these findings. These results indicate that lncRNA AK036396 can inhibit maturation and accelerate immunosuppression of PMN-MDSCs by enhancing Fcnb protein stability. ©2020 American Association for Cancer Research.The biological effects of oxidants, especially reactive oxygen species (ROS), include signaling functions (oxidative eustress), initiation of measures to reduce elevated ROS (oxidative stress), and a cascade of pathophysiological events that accompany excessive ROS (oxidative distress). Although these effects have long been studied in animal models with perturbed ROS, their actions under physiological conditions are less clear. I propose that some of the apparent uncertainty may be due to confusion of ROS with endogenously generated reactive sulfur species (RSS). ROS and RSS are chemically similar, but RSS are more reactive and versatile, and can be stored and reused. Both ROS and RSS signal via oxidation reactions with protein cysteine sulfur and they produce identical effector responses, but RSS appear to be more effective. RSS in the form of persulfidated cysteines (Cys-S-S) are produced endogenously and co-translationally introduced into proteins, and there is increasing evidence that many cellular proteins are persulfidated. A number of practical factors have contributed to confusion between ROS and RSS, and these are discussed herein. Furthermore, essentially all endogenous antioxidant enzymes appeared shortly after life began, some 3.8 billion years ago, when RSS metabolism dominated evolution. This was long before the rise in ROS, 600 million years ago, and I propose that these same enzymes, with only minor modifications, still effectively metabolize RSS in extant organisms. I am not suggesting that all ROS are RSS; however, I believe that the relative importance of ROS and RSS in biological systems needs further consideration. © 2020.

Anthracnose, caused by Colletotrichum sublineolum, is one of the major diseases in these regions, where it can cause yield losses of both grain and biomass. In this study, 114 recombinant inbred lines (RILs) derived from resistant sorghum line SC112-14 were evaluated at four distinct geographic locations in the United States for response to anthracnose. A genome scan using a high-density linkage map of 3,838 single nucleotide polymorphism (SNPs) detected two loci at 5.25 and 1.18 Mb on chromosomes 5 and 6, respectively, that explain up to 77% and 20% of the observed phenotypic variation. A bin-mapping approach using a subset of 31 highly informative RILs was employed to determine the disease response to inoculation with ten Anthracnose pathotypes in the greenhouse. A genome scan showed that the 5.25 Mb region on chromosome 5 is associated with a resistant response to nine pathotypes. Five SNP markers were developed and used to fine map the locus on chromosome 5 by evaluating 1,500 segregating F23 progenies. Based on the genotypic and phenotypic analyses of 11 recombinants, the locus was narrowed down to a 470-kb genomic region. Following a genome-wide association study based on 574 accessions previously phenotyped and genotyped, the resistance locus was delimited to a 34-kb genomic interval with five candidate genes. All five candidate genes encode proteins associated with plant immune systems, suggesting they may act in synergy in the resistance response. Copyright © The Author(s) 2020.

Attenuated vaccines are approved and marketed as good manufactiring practice (GMP)-manufactured agents whose administration might be able to induce such effects. Recent reports in mouse transplantable tumor models indicate that the rotavirus, influenza and yellow fever vaccines can be especially suitable to elicit powerful antitumor immunity against cancer following intratumoral administration. These results highlight that intratumoral anti-infectious vaccines can turn cold tumors into hot, and underscore the key role played by virus-induced type I interferon pathways to overcome resistance to immune checkpoint-targeted antibodies. © Author(s) (or their employer(s)) 2020.

Ligon lintless-2 (Li2), a dominant mutation which results in no lint fiber but normal fuzz fiber, offers insight into pathways and mechanisms that differentiate spinnable cotton from its progenitors. A genetic map developed using 1,545 F2 plants showed that marker CISP15 was 0.4 cM from Li2 and 'dominant' markers (i.e. with null alleles in the Li2 genotype) SSR7 and SSR18 showed complete linkage with Li2. Non-random distribution of markers with null alleles suggests that the Li2 phenotype results from a 176-221 kb deletion of the terminal region of chromosome 18 that may have been masked in prior pooled-sample mapping strategies. The deletion includes 10 genes with putative roles in fiber development. Two Glycosyltransferase Family 1 genes showed striking expression differences during elongation of wild-type versus Li2 fiber, and virus-induced silencing of these genes in the wild type induced Li2-like phenotypes.
