Abstract
BACKGROUND Triple-negative breast cancer (TNBC) remains the most challenging subtype of breast cancer and lacks definite treatment targets. Aerobic glycolysis is a hallmark of metabolic reprogramming that contributes to cancer progression. PFKP is a rate-limiting enzyme involved in aerobic glycolysis, which is overexpressed in various types of cancers. However, the underlying mechanisms and roles of the posttranslational modification of PFKP in TNBC remain unknown. METHODS To explore whether PFKP protein has a potential role in the progression of TNBC, protein levels of PFKP in TNBC and normal breast tissues were examined by CPTAC database analysis, immunohistochemistry staining (IHC), and western blotting assay. Further CCK-8 assay, colony formation assay, EDU incorporation assay, and tumor xenograft experiments were used to detect the effect of PFKP on TNBC progression. To clarify the role of the USP5-PFKP pathway in TNBC progression, ubiquitin assay, co-immunoprecipitation (Co-IP), mass spectrometry-based protein identification, western blotting assay, immunofluorescence microscopy, in vitro binding assay, and glycolysis assay were conducted. RESULTS Herein, we showed that PFKP protein was highly expressed in TNBC, which was associated with TNBC progression and poor prognosis of patients. In addition, we demonstrated that PFKP depletion significantly inhibited the TNBC progression in vitro and in vivo. Importantly, we identified that PFKP was a bona fide target of deubiquitinase USP5, and the USP5-mediated deubiquitination and stabilization of PFKP were essential for cancer cell aerobic glycolysis and TNBC progression. Moreover, we found a strong positive correlation between the expression of USP5 and PFKP in TNBC samples. Notably, the high expression of USP5 and PFKP was significantly correlated with poor clinical outcomes. CONCLUSIONS Our study established the USP5-PFKP axis as an important regulatory mechanism of TNBC progression and provided a rationale for future therapeutic interventions in the treatment of TNBC.

Abstract
PURPOSE Pellino3, an ubiquitin E3 ligase, prevents the formation of the death-induced signaling complex in response to TNF-α by targeting receptor-interacting protein kinase 1 (RIPK1), and bioinformatics analysis predicted an interaction between Pellino3 and caspofungin, a common antifungal drug used in clinics. This study aimed to explore the effect of caspofungin on brain injury in ischemic stroke and the underlying mechanisms. METHODS Ischemic stroke injury was induced in Sprague Dawley rats by occlusion of the middle cerebral artery (MCA) for 2 h, followed by 24 h reperfusion. PC12 cells were deprived of both oxygen and glucose for 8 h and then were cultured for 24 h with oxygen and glucose to mimic an ischemic stroke in vitro. RESULTS Animal experiments showed brain injury (increase in neurological deficit score and infarct volume) concomitant with a downregulation of Pellino3, a decreased ubiquitination of RIPK1, and an up-regulation of necroptosis-associated proteins [RIPK1, RIPK3, mixed lineage kinase domain-like protein (MLKL), p-RIPK1, p-RIPK3, and p-MLKL]. Administration of caspofungin (6 mg/kg, i.m.) at 1 h and 6 h after ischemia significantly improved neurological function, reduced infarct volume, up-regulated Pellino3 levels, increased RIPK1 ubiquitination, and down-regulated protein levels of RIPK1, p-RIPK1, p-RIPK3, and p-MLKL. PC12 cells deprived of oxygen/glucose developed signs of cellular injury (LDH release and necroptosis) concomitant with downregulation of Pellino3, decreased ubiquitination of RIPK1, and elevated necroptosis-associated proteins. These changes were reversed by overexpression of Pellino3. CONCLUSION We conclude that Pellino3 has an important role in counteracting necroptosis via ubiquitination of RIPK1 and caspofungin can suppress the brain cell necroptosis in ischemic stroke through upregulation of Pellino3.

Abstract
Necroptosis has been demonstrated to contribute to brain injury in ischemic stroke, whereas A20 can exert anti-necroptosis effect via deubiquitinating receptor-interacting protein kinase (RIPK3) at k63 and it can be cleaved by MALT1. This study aims to explore whether MALT1 is upregulated in the brain during ischemic stroke and promotes brain cell necroptosis through enhancing the degradation of A20. Ischemic stroke model was established in Sprague Dawley rats by occlusion of the middle cerebral artery (MCA) for 2 h, followed by 24 h reperfusion, which showed brain injury (increase in neurological deficit score and infarct volume) concomitant with an upregulation of MALT1, a decrease in A20 level, and increases in necroptosis-associated protein levels [RIPK3, mixed lineage kinase domain-like protein (MLKL) and p-MLKL] and k63-ubiquitination of RIPK3 in brain tissues. Administration of MALT1 inhibitor (Ml-2) at 8 or 15 mg/kg (i.p.) at 1 h after ischemia significantly improved neurological function and reduced infarct volume together with a downregulation of MALT1, an increase in A20 level and decreases in necroptosis-associated protein levels and k63-ubiquitination of RIPK3. Similarly, knockdown of MALT1 could also reduce oxygen-glucose deprivation/reoxygenation (OGD/R)-induced injury in the cultured HT22 cells coincident with an increase in A20 level and decreases in necroptosis-associated protein levels and k63-ubiquitination of RIPK3. Based on these observations, we conclude that MALT1 promotes necroptosis in stroke rat brain via enhancing the degradation of A20, which leads to a decrease in the capability of A20 to deubiquitinate RIPK3 at k63 and a subsequent compromise in counteraction against the brain cell necroptosis.

Abstract
BACKGROUND Upregulation of mitochondrial E3 ubiquitin ligase 1 (Mul1) contributes to brain injury in ischemic stroke due to disturbance of mitochondrial dynamics, and bioinformatics analysis predicts that Mul1 is a potential target of Dipsacoside B. OBJECTIVE The aim of the study was to explore whether Dipsacoside B can exert a beneficial effect on brain injury in the ischemic stroke rat via targeting Mul1. METHODS The SD rat brains or PC12 cells were subjected to 2 h-ischemia or 8 h-hypoxia plus 24 h-reperfusion or 24 h-reoxygenation to establish the ischemic stroke rat model in vivo or in vitro, which were treated with Dipsacoside B at different dosages. The brain or PC12 cell injury, relevant protein levels and mitochondrial functions were measured by methods of biochemistry, flow cytometry or Western blot. RESULTS The neurological dysfunction and brain injury (such as infarction and apoptosis) observed in the ischemic stroke rats were accompanied by increases in Mul1 and dynamin-related protein 1 (Drp1) levels along with decreases in mitofusin 2 (Mfn2) level and ATP production. These effects were attenuated by Dipsacoside B. Consistently, cell injury (necroptosis and apoptosis) occurred in the PC12 cells exposed to hypoxia concomitant with the upregulation of Mul1 and Drp1 along with downregulation of Mfn2 and mitochondrial functions (such as increases in reactive oxygen species production and mitochondrial fission and decreases in mitochondrial membrane potential and ATP production).These phenomena were reversed in the presence of Dipsacoside B. CONCLUSION Dipsacoside B can protect the rat brain against ischemic injury via inhibition of Mul1 due to the improvement of mitochondrial function.

Abstract
Complete diallel crosses with seven varieties of black pericarp rice were conducted in one year to analyze the genetic effects on main mineral elements of Fe, Zn, Mn and P contents in kernels of parents and their F1S and F2S, using the full genetic model including triploid endosperm, cytoplasmic and maternal effects on quantitative traits of seeds in cereal crops. The results indicated that the contents of all the four mineral elements were controlled by seed direct genetic effects, maternal genetic effects as well as by cytoplasmic effects. The seed direct genetic effects were more important than the maternal genetic effects for Fe, Zn, Mn contents, and seed direct additive effects constituted a major part of their genetic effects, whereas seed direct additive, maternal additive and dominant effects formed the main part in the inheritance of P content. The heritabilities of seed direct effects of the 4 mineral element contents were all highly significant. The estimate values of narrow heritabilites of seed direct genetic effects were high for Fe, Zn and Mn contents, while those of seed and maternal effects were intermediate for P content. Therefore, more attention should be paid to the single plant selection and single grain selection based on the seed mineral element contents of hybrid offspring.
