Metabolic reprogramming plays an important role in tumorigenesis. However, the metabolic types of different tumors are diverse and lack of in-depth study. Here, through analysis of big databases and clinical samples, we identified Carbamoyl phosphate synthetase I(CPS1)-deficient hepatocellular carcinoma(HCC) subtype, explored tumorigenesis mechanism of this HCC subtype, and aimed to investigate metabolic reprogramming as target for HCC prevention.

Pan-cancer study involving differentially expressed metabolic genes of 7,764 tumor samples in 16 cancer types provided by The Cancer Genome Atlas(TCGA) demonstrated that urea cycle(UC) was liver-specific and HCC-downregulated. A large-scale gene expression data analysis including a total of 2,596 HCC cases in 7 HCCDB datasets combined with a total of 17,444 hepatectomy cohort data identified a specific CPS1-deficent HCC subtype with poor clinical prognosis. In vitro and in vivo validation confirmed crucial role of CPS1 in HCC. LC-MS assay and Seahorse analysis revealed that UC dysregulation(UCD) led to the deceleration of the tricarboxylic acid(TCA) cycle, while excess ammonia caused by CPS1 deficiency activated fatty acid β-oxidation(FAO) through p-AMPK. Mechanistically, FAO provided sufficient ATP for cell proliferation and enhanced chemoresistance of HCC cells by activating FOXM1. Subcutaneous xenograft tumor models and patient-derived organoids(PDOs) were employed to identify that blocking FAO by Eto may provide therapeutic benefit to HCC patients with CPS1-deficiency.

In conclusion, our results prove a direct link between UCD and cancer stemness in HCC, define a CPS1-deficient HCC subtype through big-data mining, and provide insights for novel therapeutic for this type of HCC through targeting FAO.

The European Academy of Allergy and Clinical Immunology Anaphylaxis multidisciplinary Task Force has updated the 2014 guideline. The guideline was developed using the AGREE II framework and the GRADE approach. The evidence was systematically reviewed and recommendations were created by weighing up benefits and harms. The guideline was peer-reviewed by external experts and reviewed in a public consultation. The use of clinical criteria to identify anaphylaxis is suggested with blood sampling for the later measurement of tryptase. The prompt use of intramuscular adrenaline as first-line management is recommended with the availability of adrenaline autoinjectors to patients in the community. Pharmacokinetic data should be provided for adrenaline autoinjector devices. Structured, comprehensive training for people at risk of anaphylaxis is recommended. Simulation training and visual prompts for healthcare professionals are suggested to improve the management of anaphylaxis. It is suggested that school policies reflect anaphylaxis guidelines. The evidence for the management of anaphylaxis remains mostly at a very low level. There is an urgent need to prioritize clinical trials with the potential to improve the management of patients at risk of anaphylaxis.Cerebral vasospasm (CVS) is a frequent and serious neurosurgical complication, without sufficient therapy. This retrospective study was performed to analyze if nimodipine can improve prognosis and reduces ischemia secondary to delayed CVS after intracranial tumor surgery. A retrospective review was performed over the years 2011 to 2012 for patients with an anterior cranial fossa tumor and underwent intracranial tumor surgery. And the surgical field was soaked with nimodipine solution or normal saline. Transcranial Doppler ultrasonography was used to measure velocity in the middle cerebral artery (MCA) and the distal extracranial internal carotid artery (eICA). Follow-up was performed using the Glasgow Outcome Scale (GOS) after discharge. 94 patients that met the inclusion criteria. They included 50 males and 44 females, with a mean age of 49.6 yr. In the nimodipine group, CVS occurred in 13 patients; 9 patients had CVS between 4 and 7 days, and 4 had CVS between 8 and 14 days. In the normal saline group, 19 patients had CVS, 3 presented with CVS within 3 days, 11 between 4-7 days and 5 between 8-14 days. A significant difference in the occurrence of CVS was observed between the two groups. Preoperative and postoperative the MCA velocities were compared, revealing a significant change in the normal saline group but not in the nimodipine group. Nimodipine markedly improves prognosis and significantly reduces ischemia secondary to delayed CVS after intracranial tumor surgery, as well as the risks of mortality and morbidity.Overt expression of brain glucocorticoid receptor (GR) leads to elevation of glutamate release causes cerebral excitotoxicity which in turn produce neuropsychological disorders. The aim of our work is to study the consequence of 3-O-Acetyl-11-keto-β-boswellic acid (AKBA) on chronic unpredictable mild stress (CUMS) induced HPA axis dysregulation in relative to glutamate and GABA irregularity in depressive rats. AKBA (5, 10 &15mg/kg) was administered for 28 days parallel with CUMS induction in rats. Behavioural studies, tail suspension test (TST), open field exploratory (OFT) and forced swim test (FST) were performed. Biochemical studies including plasma corticosterone, glutamate GABA and glutamic acid decarboxylase (GAD) enzyme activity were studied. Glucocorticoid receptor expression and brain histology were studied to observe the effect of AKBA. CUMS induction results in depressive state of the animals were confirmed by the sucrose preference test. The administration of AKBA significantly reduced the immobility time and improved the exploratory behaviour. Plasma corticosterone and brain glutamate level was decreased and GABA level were increased significantly evident with GAD activation in AKBA-treated animals, further confirmed with decreased GR expression improves architecture of prefrontal cortex region. Correlation study illustrates behavioural improvements undeviating the biochemical alteration and GR expression after AKBA treatment during depression. AKBA significantly reversed the CUMS-induced glutamate/GABA abnormalities through the adaptation of central HPA axis regulation. Hence this study concludes that AKBA can be a better alternative to treat depressive disorders.

Feed shortage is a factor restricting animal production in the tropics, therefore how to use natural woody plant resources as animal feed is an important strategy.

Under the dual stress of an anaerobic and acidic environment, the microbial response during the fermentation of paper mulberry (PM) silage was found to be sensitive. The Gram-negative bacteria and mould died, and the dominant microbial community rapidly shifted to Gram-positive bacteria, resulting in a large reduction in microbial diversity and abundance. Exogenous bran additives interfered with the stress effects of the woody silage environment. Wheat bran (WB) accelerated the response of microorganisms to the anaerobic stress, and lactic acid bacteria became the dominant microbial community, thereby enhancing the lactic acid fermentation of silage, affecting the metabolic pathways of microorganisms, and improving the flavour and quality of the silage. Addition of rice bran made Enterobacter and Clostridium species quickly respond to the stress of the silage environment and become the predominant bacterial groups. In particular, anaerobic and spore-forming Clostridium species showed a strong tolerance to the silage environment, leading to butyric acid fermentation and protein degradation of the silage, and reducing its fermentation quality.

The PacBio single-molecule real-time (SMRT) sequencing technology accurately revealed the microbial co-occurrence network and fermentation mechanism of silage. Our results indicate that PM can be used in combination with WB to prepare high-quality silage for animal production. © 2021 Society of Chemical Industry.

B-precursor cell acute lymphoblastic leukemia (B-ALL) in adults is an aggressive and challenging condition, and patients with relapsed/refractory (R/R) disease after allogeneic stem cell transplantation (SCT), or noncandidates for SCT, have a particularly poor prognosis. The authors investigated the activity of the Fc-modified anti-CD19 antibody tafasitamab in adults with R/R B-ALL (NCT01685021).

Adults with R/R B-ALL received single-agent tafasitamab 12 mg/kg weekly for up to four 28-day cycles. Patients with complete remission (with or without neutrophil/platelet recovery; complete remission [CR] or complete remission with incomplete count recovery [CRi]) after cycles 2, 3, or 4 could continue tafasitamab every 2 weeks for up to 3 further months. Sulfosuccinimidyl oleate sodium Mitophagy inhibitor The primary end point was overall response rate (ORR).

Twenty-two patients were treated (median, 2 prior lines of therapy; range, 1-8). Six patients completed 2 cycles, and 2 of these patients responded for an ORR of 9%; 16 patients (73%) progressed before thoimmunotherapy combinations and MRD settings should be explored.Mirabegron is a selective β₃-adrenergic receptors agonist, which has been recently shown to improve metabolic health in rodents and humans. In this study, we investigated the effects of 2-week mirabegron treatment on the metabolic parameters of mice with a diet-induced obesity (DIO). C57BL/6JUnib mice were divided into control (CTR) and obese (OB) groups treated with vehicle, and an OB group treated with mirabegron (OB + MIRA). The obese groups were fed a high-fat diet for 12 weeks. Mirabegron (10 mg/kg/day) was administrated orally by gavage from weeks 10-12. After 2 weeks of mirabegron treatment, the energy expenditure was assessed with indirect calorimetry. Blood glucose, insulin, glycerol, free fatty acids (FFA), thiobarbituric acid reactive substance (TBAR), and tumour necrosis factor (TNF)-α levels were also assessed, and the HOMA index was determined. Liver tissue, brown adipose tissue (BAT), and inguinal white adipose tissue (iWAT) samples were collected for histological examination. The protein expressions of uncoupling protein 1 (UCP1) and mitochondrial transcription factor A (TFAM) were assessed using western blotting of the BAT and iWAT samples. In this study, mirabegron increased the energy expenditure and decreased adiposity in OB + MIRA. Increased UCP1 expression in BAT without changes in iWAT was also found. Mirabegron decreased circulating levels of FFA, glycerol, insulin, TNF-α, TBARS and HOMA index. DIO significantly increased the lipid deposits in the liver and BAT, but mirabegron partially reversed this change. Our findings indicate that treatment with mirabegron decreased inflammation and improved metabolism in obese mice. This effect was associated with increased BAT-mediated energy expenditure, but not iWAT beiging, which suggests that mirabegron might be useful for the treatment of obesity and diabetes.
