ACOT7 promotes retinoblastoma resistance to vincristine by regulating fatty acid metabolism reprogramming.

The rate of vincristine (VCR) resistance in the treatment of retinoblastoma (RB) is relatively high, and the exact role and mechanism of autophagy and fatty acid (FA) metabolism in RB are still unknown. The aim of this study was to elucidate the molecular mechanism by which acyl-CoA thioesterase 7 (ACOT7) regulates FA metabolism and autophagy, which may lead to potential therapeutic strategies for RB. In the present study, the relationship between FA metabolism and cellular drug sensitivity was evaluated through ACOT7 overexpression or inhibition tests in RB-resistant cells. The lipase inhibitor orlistat and the autophagy inhibitor CQ were used to determine the effects of ACOT7 on FA metabolism, autophagy, and cellular drug sensitivity, as well as the therapeutic value of ACOT7 targeting. The results showed that ACOT7 was upregulated in VCR-resistant RB cells, significantly enhancing cell resistance and indicating that ACOT7 may serve as a biomarker for VCR resistance in RB cells. Knockdown of ACOT7 inhibited FA metabolism and reduced cell viability in VCR-resistant RB cells. The effect of ACOT7 overexpression was opposite to that of ACOT7 knockdown, and ACOT7 overexpression promoted autophagy in VCR-resistant RB cells. After treatment with orlistat or CQ, FA metabolism in VCR-resistant RB cells decreased, cell viability and autophagy were inhibited, EMT was inhibited, and the sensitivity of RB cells to VCR was increased. In conclusion, ACOT7 knockdown can mediate FA metabolism to inhibit autophagy and the migration of RB cells, thereby improving the sensitivity of RB cells to VCR.

Chimeric antigen receptor therapy meets mRNA technology.

Genetically engineered immune cells expressing chimeric antigen receptors (CARs) have emerged as a new game changer in cancer immunotherapy. The utility of CAR T cell therapy against hematological malignancies has been validated in clinical practice. Other CAR immune cells are currently under investigation to improve the potency of CAR therapy in solid tumors. As a new class of therapeutic modalities, mRNA-based therapeutics hold enormous potential beyond COVID-19 mRNA vaccines. Arming immune cells with mRNA-encoded CARs represents a new frontier in cancer and beyond, enabling in vivo generation of CAR cells without causing transgene integration. In this review, we summarize recent advances in mRNA-based CAR immunotherapies and highlight their opportunities and challenges for the development of a new generation of living drugs.

Discussion on treatment courses of brucellosis with spondylitis - a report of two cases.

Human Brucellosis is a zoonotic contagious disease caused by Brucella infection and is common throughout the world, which can travel through the bloodstream to various organs. Brucellar spondylitis(BS) is the foremost cause of brucellosis's debilitating and disabling complications. We report two sisters with brucellosis complicated by lumbar spondylodiscitis accompanied by cold abscess formation. The diagnosis was based on their symptoms, epidemiological characteristics, laboratory and magnetic resonance imaging(MRI) results. Our therapeutic strategy in these two cases indicate that drug combination and prolongation of the use of antibiotics is a therapeutic strategy worthy of popularizing to reach a greater clearance rate of the infection.

A PEG-lipid-free COVID-19 mRNA vaccine triggers robust immune responses in mice.

COVID-19 mRNA vaccines represent a completely new category of vaccines and play a crucial role in controlling the COVID-19 pandemic. In this study, we have developed a PEG-lipid-free two-component mRNA vaccine (PFTCmvac) by formulating mRNA encoding the receptor binding domain (RBD) of SARS-CoV-2 into lipid-like nanoassemblies. Without using polyethylene glycol (PEG)-lipids, the self-assembled PFTCmvac forms thermostable nanoassemblies and exhibits a dose-dependent cellular uptake and membrane disruption, eventually leading to high-level protein expression in both mammalian cells and mice. Vaccination with PFTCmvac elicits strong humoral and cellular responses in mice, without evidence of significant adverse reactions. In addition, the vaccine platform does not trigger complement activation in human serum, even at a high serum concentration. Collectively, the PEG-lipid-free two-component nanoassemblies provide an alternative delivery technology for COVID-19 mRNA vaccines and opportunities for the rapid production of new mRNA vaccines against emerging infectious diseases.

A Case of Secondary Pulmonary Syphilis - The Utility of mNGS in Bronchoalveolar Lavage Fluid: A Case Report.

Syphilis is a sexually transmitted infectious disease caused by Treponema pallidum. Here, we report a rare case of secondary pulmonary syphilis, which was diagnosed by metagenomic next-generation sequencing (mNGS) in bronchoalveolar lavage fluid (BALF). Direct pulmonary involvement by T. pallidum was suggested by a positive mNGS result in BALF. One month after treatment with benzathine penicillin G (2.4 million units, three doses), a repeated CT scan showed the radiological resolution. To our knowledge, this is the first reported case of secondary pulmonary syphilis diagnosed by mNGS in BALF.

Induction of Resistance of Antagonistic Bacterium Burkholderia contaminans to Postharvest Botrytis cinerea in Rosa vinifera.

In order to study the problem that grapes are vulnerable to microbial infection and decay during storage, a method based on antagonistic Burkholderia contaminans against postharvest Botrytis cinerea of Rosa vinifera was proposed in this paper. The method tested the resistance induction mechanism of Botrytis cinerea after harvest and determined the fruit decay rate treated by antagonistic Burkholderia contaminans. The results showed that the antagonistic bacterium B-1 had bacteriostatic effect on many common pathogens of fruits and vegetables to a certain extent, and the bacteriostatic range was wide. Among them, the inhibition rate of Fusarium moniliforme was 75.5% and that of Botrytis cinerea was 51.2%. After testing, it can be found that antagonistic bacteria have an inhibitory effect on pathogenic fungi and have an effect on phenylpropane metabolic pathway, reactive oxygen species metabolic pathway, and the activities of other resistance-related enzymes. Through comparison, it can be found that the antagonistic Burkholderia contaminans has a strong antibacterial mechanism against Botrytis cinerea of rose grape after harvest. The fruit treated with antagonistic B Burkholderia B-1 has significantly reduced the decay rate and increased the activity of antibacterial active protein.

Blood pressure states transitions among bus drivers: the application of multi-state Markov model.

PURPOSE: To explore the transition patterns among different levels of blood pressure for bus drivers. METHODS: A follow-up study was conducted to investigate the transition probabilities of three blood pressure states, the sojourn time in each state, the survival probabilities, and the risk factors affecting hypertension progression. Based on 5618 blood pressure measurements of 1883 Chinese bus drivers from 2017 to 2021, a multi-state Markov model was established. RESULTS: The mean age of participants was 41.43 ± 6.71 years, and 82.37% were male. The probabilities from normal state to hypertension within 1-year follow-up were 4.60% (male) and 2.13% (female); however, the corresponding changes over a 3-year follow-up had a significant increase to 20.27% (male) and 7.98% (female). The sojourn time of normal state and elevated state was 1.82 ± 0.09 years and 1.98 ± 0.08 years, respectively. The male participants, the increasing age, BMI, CHOL and TG were risk factors for progression from normal state to elevated state, and/or from elevated state to hypertensive state (HR: 1.04-2.53). CONCLUSIONS: Early preventive measures on the progression of hypertension should be taken for Chinese bus drivers, and at least one physical examination per year is strongly recommended. The government and bus companies should pay more attention to these kinds of bus drivers with high probabilities of hypertension: male, older than 40 years, with the higher values of BMI and blood lipid. The derived findings of sojourn time, transition probabilities and survival probabilities can provide reference for health professionals to make targeted intervention to reduce bus drivers' hypertension occurrence.

Altered fecal microbial and metabolic profile reveals potential mechanisms underlying iron deficiency anemia in pregnant women in China.

The gut microbiome and its metabolism may provide crucial insight into the cause of iron deficiency anemia (IDA) in pregnant women. This study aimed to investigate the effect of the gut microbiome and its related metabolites on pregnant women with iron deficiency (ID) and IDA. Maternal cubital venous blood and stool samples were collected from healthy control pregnant women (HC, non-anemic, n=10), pregnant women with ID non-anemia (ID, n=10), and IDA (n=10). All groups were subjected to fecal metagenomics and metabolomics. The composition and function of the gut microbiome were then compared in pregnant women with ID and IDA with HC after excluding the possibility of inflammation and insufficient iron absorption capacity. Whole-genome shotgun libraries were prepared by quantifying metagenomic DNA samples with Quant-iT PicoGreen dsDNA Assay. The levels of 41 microbial species, including 21 Streptococci and ten metabolites (catechol), which could serve as siderophores, were increased. In contrast, 3 Bacteroides and six metabolites were decreased in pregnant women with IDA (p<0.05). The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis indicated that the bio-pathways, including biosynthesis of siderophore group non-ribosomal peptides (p<0.01), ABC transporters (p<0.05) and membrane transport of the gut microbiota (p<0.01) in IDA patients were expressed differently compared with HC. Correlation analysis also indicates that these increased bacteria formed strong co-occurring relationships with metabolites in the occurrence and development of IDA in pregnant women. The current study identified that streptococci and catechol (fecal metabolite) were significantly increased in pregnant women with IDA. Therefore, adjusting the intestinal homeostasis using long-term living and eating habits on oral Streptococcus in pregnant women with IDA before iron supplementation may be more conducive to iron supplementation, thus providing novel therapies for IDA.

FABP4 knockdown suppresses inflammation, apoptosis and extracellular matrix degradation in IL-1ß-induced chondrocytes by activating PPARγ to regulate the NF-κB signaling pathway.

Osteoarthritis (OA) is a common degenerative disease that can lead to severe joint pain and loss of function, seriously threatening the health and normal life of patients. At present, the pathogenesis of OA remains to be clarified. Recent studies have shown that fatty acid­binding protein 4 (FABP4) is increased in the plasma and synovial fluid of patients with OA. However, the effect of FABP4 on OA is unclear. The present study established IL­1ß­induced ATDC5 cells with FABP4 knockdown. Next, cell viability was detected with Cell Counting Kit­8 assay. The content of inflammatory factors, prostaglandin E2 and glycosaminoglycan (GAG) was detected via ELISA. The levels of reactive oxygen species (ROS) and superoxide dismutase (SOD) in cells were detected by using ROS and SOD kits, respectively. TUNEL staining was used to detect the apoptosis level. Western blotting was used to detect the expression levels of proteins. The results revealed that FABP4 was upregulated in IL­1ß­induced ATDC5 cells. Knockdown of FABP4 increased cell viability, reduced inflammatory damage, oxidative stress and apoptosis in IL­1ß­induced ATDC5 cells. Following FABP4 knockdown, the expression of matrix metalloproteinases (MMP3, MMP9 and MMP13) of IL­1ß­induced ATDC5 cells was reduced, and the expression of GAG was promoted. FABP4 knockdown also inhibited the expression of NF­κB p65 and enhanced peroxisome proliferator­activated receptor (PPAR)γ expression. However, the presence of PPARγ inhibitor blocked the aforementioned effects of FABP4 on IL­1ß­induced ATDC5 cells. In conclusion, FABP4 knockdown suppressed the inflammation, oxidative stress, apoptosis and extracellular matrix degradation of IL­1ß­induced chondrocytes by activating PPARγ to inhibit the NF­κB signaling pathway.

Secreted Expression of mRNA-Encoded Truncated ACE2 Variants for SARS-CoV-2 via Lipid-Like Nanoassemblies.

The transfer of foreign synthetic messenger RNA (mRNA) into cells is essential for mRNA-based protein-replacement therapies. Prophylactic mRNA COVID-19 vaccines commonly utilize nanotechnology to deliver mRNA encoding SARS-CoV-2 vaccine antigens, thereby triggering the body's immune response and preventing infections. In this study, a new combinatorial library of symmetric lipid-like compounds is constructed, and among which a lead compound is selected to prepare lipid-like nanoassemblies (LLNs) for intracellular delivery of mRNA. After multiround optimization, the mRNA formulated into core-shell-structured LLNs exhibits more than three orders of magnitude higher resistance to serum than the unprotected mRNA, and leads to sustained and high-level protein expression in mammalian cells. A single intravenous injection of LLNs into mice achieves over 95% mRNA translation in the spleen, without causing significant hematological and histological changes. Delivery of in-vitro-transcribed mRNA that encodes high-affinity truncated ACE2 variants (tACE2v mRNA) through LLNs induces elevated expression and secretion of tACE2v decoys, which is able to effectively block the binding of the receptor-binding domain of the SARS-CoV-2 to the human ACE2 receptor. The robust neutralization activity in vitro suggests that intracellular delivery of mRNA encoding ACE2 receptor mimics via LLNs may represent a potential intervention strategy for COVID-19.

Study on the occurrence law and green control of grape gray mold from the perspective of ecological balance.

With the increase of grape planting years, the base number of pathogenic seedlings and insect population is gradually rising. In addition, the introduction, breeding system and control of seedlings are not standardized and other human factors, the occurrence of Botrytis cinerea(B.cinerea) on grape is becoming more and more serious, resulting in a prominent problem of yield decline. In this paper, the occurrence of B.cinerea was monitored and its control effect was tested from the perspective of ecological balance. Finally, the biological characteristics and control of B.cinerea were studied. The spore catcher was used to catch the pathogen spores of B. cinerea, and the amount of sporangium scattering reached its peak from August to September Spore scattering is affected by meteorological factors, and the temperature has reached a very significant level, and the low temperature and high humidity conditions are conducive to the disease; The results showed that the resistance frequency of 304 B.cinereastrains to carbendazim, boscalid, pyrimethanil was higher than 50%; the volatile compounds produced by yeast (Trichosproom sp.) YE-3-2 significantly inhibited the growth of B.cinerea (inhibition rate was 62.93%, according to the occurrence regularity of B.cinerea, the accurate and effective agricultural measures had a good control effect on B.cinerea, which could improve the quality of grape fruit and provide some help for the prevention of grape gray mold.

MiR-122-5p knockdown protects against APAP-mediated liver injury through up-regulating NDRG3.

MiR-122-5p serves as a novel biomarker for drug-induced liver injury (DILI), but its function in DILI remains unclear. The present study, therefore, explored the function and potential mechanism of miR-122-5p in DILI. Sprague-Dawley (SD) rats were treated with miR-122-5p antagomir, and then DILI was induced in the rats by acetaminophen (APAP). To determine the effect of miR-122-5p on DILI in vivo, liver injury was examined by HE staining and TUNEL assays, and the levels of serum ALT and AST were determined using an automated clinical chemistry analyzer. To further reveal the mechanism of miR-122-5p in DILI, THLE-2 (normal liver cell line) cells were transfected with miR-122-5p mimic and inhibitor, NDRG3, and siNDRG3, and then injured by APAP. The relationship between miR-122-5p and NDRG3 was determined by TargetScan, luciferase reporter assay, and Western blot. The viability and apoptosis of THLE-2 cells were detected by CCK-8 and flow cytometry, respectively. The levels of mRNA and protein in vivo and in vitro were measured by qRT-PCR and Western blot, respectively. APAP induced liver injury and increased the levels of ALT, AST, and miR-122-5p in DILI rats. However, these effects of APAP were attenuated by miR-122-5p antagomir. MiR-122-5p negatively regulated NDRG3 expression. APAP decreased cell viability, apoptosis resistance, and Bcl-w and Bcl-2 levels whereas increased Bax level in THLE-2 cells. However, these effects of APAP on THLE-2 cells were promoted by miR-122-5p up-regulation but inhibited by miR-122-5p knockdown. MiR-122-5p knockdown protects against APAP-mediated liver injury through up-regulating NDRG3.

Knockdown of NHP2 inhibits hepatitis B virus X protein-induced hepatocarcinogenesis via repressing TERT expression and disrupting the stability of telomerase complex.

Hepatitis B virus X protein (HBx) is highly expressed in HBV-infected hepatocellular carcinoma (HCC) and upregulates transcriptional activation of telomerase reverse transcriptase (TERT). NHP2 is a component of the telomerase complex and also increased in HCC. However, whether NHP2 could accelerate HCC caused by HBx overexpression remains unknown. This study intended to investigate the effects of NHP2 knockdown on HBx-overexpressed HCC and uncover the potential mechanism. Results showed that after HBx overexpression, the expression of TERT and NHP2 was increased. NHP2 knockdown inhibited cell proliferation, colony formation and telomerase activity, while promoting cell apoptosis in PLC/PRF5 cells with or without HBx overexpression. Moreover, the protein expression of TERT and HBx was inhibited, pro-apoptotic proteins Bax and cleaved-caspase3 expression was enhanced, whereas anti-apoptotic protein Bcl-2 level was reduced upon NHP2 silencing in PLC/PRF5 cells with or without HBx upregulation. The interaction between NHP2 and TERT was also confirmed. Treatment with shRNA-NHP2-1 inhibited tumor growth in xenograft model, and the alterations of related proteins were consisted with in vitro results. In conclusion, knockdown of NHP2 could inhibit the proliferation of hepatoma cells overexpressing HBx via inhibiting TERT expression.

The rCC16 Protein Protects Against LPS-Induced Cell Apoptosis and Inflammatory Responses in Human Lung Pneumocytes.

OBJECTIVE: Our previous clinical study showed that low lung levels of CC16 strongly influence the occurrence and development of ARDS. The aim of the present study was to evaluate the therapeutic effect of rCC16 on LPS-induced inflammation in A549 cells and to determine its mechanism. METHODS: Cell apoptosis and inflammation was induced by LPS stimulation. The cytotoxic effect of rCC16 was evaluated using the MTT assay. Cytokine levels were determined using enzyme-linked immunosorbent assays. The molecular mechanism of rCC16 was investigated by analyzing relevant signaling pathways. RESULTS: The LPS treatment of A549 cells significantly decreased cell viability, increased the levels of the apoptotic proteins Bax, Bak and Cleaved Caspase-3, the secretion of inflammatory cytokines, and the expression levels of TLR4, p-NF/κB, MAPK proteins. While the levels of Bcl-2, p-AKT, p-mTOR, p-ERK1/2, NF/κB, p-AMPK, and p-p38 were significantly decreased in LPS-treated A549 cells. Our experimental results also confirmed that rCC16 inhibited LPS-induced apoptosis, promoted A549 cell proliferation by activating the PI3K/AKT/mTOR/ERK1/2 pathway, and inhibited the release of certain inflammatory factors, especially HMGB1, through dephosphorylation and inactivation of the TLR4/NF-κB/AMPK signaling pathways. CONCLUSION: These results highlight the potential utility of CC16 as an important cytokine for the prevention or treatment of inflammation and show that CC16 may play an important role in the future clinical treatment of ARDS.

4,5-di-O-caffeoylquinic acid methyl ester isolated from Lonicera japonica Thunb. targets the Keap1/Nrf2 pathway to attenuate H2O2-induced liver oxidative damage in HepG2 cells.

BACKGROUND: 4,5-di-O-caffeoylquinic acid methyl ester (4,5-CQME) is a caffeoylquinic acid (CQA) isolated from Lonicera japonica Thunb., a traditional Chinese medicine. To date, the biological activity of 4,5-CQME has not been fully investigated. PURPOSE: The aim of the current study was to explore the anti-oxidative activity and the underlying mechanism of 4,5-CQME. METHODS: MTT assay was used to evaluate the cytoprotective effect of 4,5-CQME. DCFH-DA was used as a fluorescence probe to detect intracellular ROS. The mitochondrial membrane potential was detected using the fluorescent probe JC-1. MDA and GSH levels were measured using MDA and GSH commercial kits, respectively. Apoptosis assay was performed using the Annexin V-FITC/PI method. The functional mechanism of 4,5-CQME was investigated by analyzing relative signaling pathways through immunofluorescent staining, quantitative PCR and western blot analysis. RESULTS: HepG2 cells were incubated with different concentrations of 4,5-CQME for 12 h before exposure to 500 µM H2O2 for 3 h. 4,5-CQME attenuated H2O2-induced oxidative damage and had a higher cytoprotective effect than 3-caffeoylquinic acid, 3-caffeoylquinic acid methyl ester, or 4,5-di-O-caffeoylquinic acid. 4,5-CQME also reduced ROS and MDA levels and rescued GSH depletion. Western blots demonstrated that 4,5-CQME decreased Bax/Bcl-2 and Bak levels. A mechanistic study confirmed that 4,5-CQME significantly suppressed H2O2-induced MAPKs phosphorylation but had little effect on MAPKs phosphorylation under normal conditions. By contrast, 4,5-CQME induced AKT phosphorylation in the presence or absence of H2O2. 4,5-CQME also regulated the Keap1/Nrf2 signaling pathway and enhanced both the mRNA and protein expressions of HO-1 and NQO1. The anti-oxidative effect of 4,5-CQME was greatly abolished by co-incubation with the Nrf2 inhibitor ML385 or PI3K inhibitor wortmannin. CONCLUSIONS: Taken together, these results showed that 4,5-CQME offered significant protection against H2O2-induced oxidative stress, and its effect was in part due to the modulation of the Keap1/Nrf2 pathway.

3,4,5-Tri-O-caffeoylquinic acid methyl ester isolated from Lonicera japonica Thunb. Flower buds facilitates hepatitis B virus replication in HepG2.2.15 cells.

Caffeoylquinic acids are well known for their prominent antiviral activities. Beyond our expectations, we initially found 3,4,5-Tri-O-caffeoylquinic acid methyl ester (3,4,5-CQME) from L. japonica can facilitate HBV DNA and antigens secretion. This study aimed to investigate its underlying molecular mechanism. The results indicate that 3,4,5-CQME signally increased intracellular and secreted HBsAg levels by more than two times in HepG2.2.15 cells and HepAD38 cells. Furthermore, levels of HBeAg, HBV DNA and RNA were significantly enhanced by 3-day 3,4,5-CQME treatment; it didn't directly affect intracellular cccDNA amount, although it slightly increased cccDNA accumulation as a HBV DNA replication feedback. In addition, treatment with 3,4,5-CQME significantly induced HBx protein expression for viral replication. We utilized a phospho-antibody assay to profile the signal transduction change by 3,4,5-CQME to illuminate its molecular mechanism. The results indicate that treatment with 3,4,5-CQME activated AKT/mTOR, MAPK and NF-κB pathways verified by immunoblot. Moreover, 3,4,5-CQME upregulated the expression of nuclear transcriptional factors PGC1α and PPARα. In short, 3,4,5-CQME promotes HBV transcription and replication by upregulating HBx expression and activating HBV transcriptional regulation-related signals. As caffeoylquinic acids are widely present in traditional Chinese medicines, the risk of intaking caffeoylquinic acids-containing herbs for hepatitis B treatment requires more evaluation and further research.

Effects of a novel biflavonoid of Lonicera japonica flower buds on modulating apoptosis under different oxidative conditions in hepatoma cells.

BACKGROUND: In our previous work, we purified a novel biflavonoid named Japoflavone D (JFD) from Lonicera japonica flower buds. Biflavonoids are chemical compounds characterized by their high levels of antioxidative activity. PURPOSE: The present study aimed to investigate the function and molecular mechanism of JFD under different oxidative conditions in hepatoma cells. METHODS: MTT assay and apoptosis assay were used to evaluate the cytotoxic effect of JFD. The activities of SOD and CAT were detected to evaluate the oxidative level. Oxidative stress was induced by H2O2 stimulation. The molecular mechanism of JFD was investigated by analyzing relative signaling pathway. RESULTS: JFD inhibited cell viability in all hepatoma cell lines we examined. Under quiescent conditions, JFD treatment of SMMC-7721 cells resulted in upregulation of AKT/mTOR signal pathway and ERK activities and downregulation of KEAP1/NRF2/ARE signaling axis, together with apoptosis. However, under oxidative stress, JFD played a quite different role. Treatment of JFD suppressed the activation of ERK and mTOR and activated the KEAP1/NRF2/ARE signaling axis, which is a predominant regulator of cytoprotective responses to oxidative stress, thereby lessening the damage caused by excess reactive oxygen species (ROS). A molecular docking analysis suggested that JFD may interrupt the interaction between KEAP1 and NRF2 by competitively anchoring to the NRF2 binding site on KEAP1. CONCLUSION: The results indicate that JFD functions as a potent antioxidant and plays dual roles in modulating apoptosis under different oxidative conditions. JFD has the potential to be developed as a protective drug for diseases related with excess ROS.
