Abstract
Metabolic-associated fatty liver disease (MAFLD), characterized primarily by hepatic steatosis, has become the most prevalent liver disease worldwide, affecting approximately two-fifths of the global population. The pathogenesis of MAFLD is extremely complex, and to date, there are no approved therapeutic drugs for clinical use. Considerable evidence indicates that various metabolic disorders play a pivotal role in the progression of MAFLD, including lipids, carbohydrates, amino acids, and micronutrients. In recent years, the medicinal properties of natural products have attracted widespread attention, and numerous studies have reported their efficacy in ameliorating metabolic disorders and subsequently alleviating MAFLD. This review aims to summarize the metabolic-associated pathological mechanisms of MAFLD, as well as the natural products that regulate metabolic pathways to alleviate MAFLD.

Adipose-derived mesenchymal stem cells (MSCs) are a superior cell source for bone tissue engineering. Bioact Mater 2024; 34:51-63. [PMID: 38186960 PMCID: PMC10770370 DOI: 10.1016/j.bioactmat.2023.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/19/2023] [Revised: 11/26/2023] [Accepted: 12/02/2023] [Indexed: 01/09/2024] Open
Abstract
Effective bone regeneration through tissue engineering requires a combination of osteogenic progenitors, osteoinductive biofactors and biocompatible scaffold materials. Mesenchymal stem cells (MSCs) represent the most promising seed cells for bone tissue engineering. As multipotent stem cells that can self-renew and differentiate into multiple lineages including bone and fat, MSCs can be isolated from numerous tissues and exhibit varied differentiation potential. To identify an optimal progenitor cell source for bone tissue engineering, we analyzed the proliferative activity and osteogenic potential of four commonly-used mouse MSC sources, including immortalized mouse embryonic fibroblasts (iMEF), immortalized mouse bone marrow stromal stem cells (imBMSC), immortalized mouse calvarial mesenchymal progenitors (iCAL), and immortalized mouse adipose-derived mesenchymal stem cells (iMAD). We found that iMAD exhibited highest osteogenic and adipogenic capabilities upon BMP9 stimulation in vitro, whereas iMAD and iCAL exhibited highest osteogenic capability in BMP9-induced ectopic osteogenesis and critical-sized calvarial defect repair. Transcriptomic analysis revealed that, while each MSC line regulated a distinct set of target genes upon BMP9 stimulation, all MSC lines underwent osteogenic differentiation by regulating osteogenesis-related signaling including Wnt, TGF-β, PI3K/AKT, MAPK, Hippo and JAK-STAT pathways. Collectively, our results demonstrate that adipose-derived MSCs represent optimal progenitor sources for cell-based bone tissue engineering.

BMP4 participates in the pathogenesis of PCOS by regulating glucose metabolism and autophagy in granulosa cells under hyperandrogenic environment. J Steroid Biochem Mol Biol 2023; 235:106410.

Abstract
Polycystic ovary syndrome (PCOS) is a complex reproductive endocrine disease characterized by ovulation dysfunction with multiple etiologies and manifestations, and it is widely believed that the disorders of hyper-androgen and glucose metabolism play a key role in its progression. There has been evidence that bone morphogenetic protein 4 (BMP4) is essential for the regulation of granulosa cells, but whether it regulates metabolism level of granulosa cells under hyperandrogenic environment remains unclear. In this study, Gene Expression Omnibus, clinical data and serum of PCOS patient were collected to detect androgen and BMP4 levels. KGN cells exposed to androgens as a model for simulating PCOS granulosa cells. Lactate/pyruvate kits, and Extracellular Acidification Rate and Oxygen Consumption Rate assay were performed to detect glycolysis and autophagy levels of granulosa cells. Lentivirus infection was used to investigate the effects of BMP4 on granulosa cells. RNA-seq were performed to explore the special mechanism. We found that BMP4 was increased in PCOS patients with hyper-androgen and granulosa cells with dihydrotestosterone treatment. Mechanically, on the one hand, hyperandrogenemia can up-regulate BMP4 secretion and induce glycolysis and autophagy levels. On the other hand, we found that hyperandrogenic-induced YAP1 upregulation may mediate BMP4 to increase glycolysis level and decrease autophagy, which plays a protective role in granulosa cells to ensure subsequent energy utilization and mitochondrial function. Overall, we innovated on the protective effect of BMP4 on glycolysis and autophagy disorders induced by excessive androgen in granulosa cells. Our study will provide guidance for future understanding of PCOS from a metabolic perspective and for exploring treatment options.

Cureus 2023; 15:e48738. [PMID: 37965235 PMCID: PMC10642626 DOI: 10.7759/cureus.48738] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 11/13/2023] [Indexed: 11/16/2023] Open
Abstract
BACKGROUND In the current study, we aimed to assess the levels of Gremlin 1, an adipokine with a rich repertoire of metabolic effects, in association with the glycemic and lipid parameters after sleeve gastrectomy. MATERIAL AND METHODS This study was conducted on 31 males with obesity aged 25 to 50 years who underwent sleeve gastrectomy. Plasma Gremlin 1 levels were evaluated using enzyme-linked immunosorbent assay (ELISA) at baseline and 6-12 months after the operation, along with body mass index, insulin, glucose, and lipid profile. RESULTS Plasma Gremlin 1 levels were elevated (148.19±17.43 vs. 193.29±19.82 ng/mL, p < 0.05) after sleeve gastrectomy. This was accompanied by a decrease in body mass index (from 51.47±1.71 to 39.23±1.56 kg/m2, p < 0.05). Insulin and Homeostatic Model Assessment for Insulin Resistance (HOMA-IR) also exhibited a significant decrease (19.69±1.81 vs. 8.98±1.09 mIU/L and 6.52±0.98 vs. 2.57±0.036 p < 0.05, respectively) in the postoperative period. Total cholesterol levels were significantly increased after surgery (4.29±0.16 to 5.10±0.16, p < 0.05). Pearson correlation analysis showed that Gremlin 1 was positively correlated with insulin before surgery, but there was no significant correlation after surgery. CONCLUSION The circulating Gremlin 1 levels were elevated postoperatively among our participants. The improvement in insulin sensitivity appears to be independent of the reported antagonistic effects of Gremlin 1.

BMP4 upregulates glycogen synthesis through the SMAD/SLC2A1 (GLUT1) signaling axis in hepatocellular carcinoma (HCC) cells. Cancer Metab 2023; 11:9. [PMID: 37443106 DOI: 10.1186/s40170-023-00310-6] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2022] [Accepted: 06/26/2023] [Indexed: 07/15/2023] Open
Abstract
BACKGROUND Excessive hepatic glycogen accumulation benefits tumorigenesis and cancer cell survival. We previously reported that BMP4 has the strongest ability to promote glycogenesis among the 14 BMPs in hepatocytes and augmented hepatocellular carcinoma (HCC) cell survival under hypoxia and hypoglycemia conditions by promoting the glycolysis pathway. However, the mechanism underlying BMP4's effect on glycogenesis in HCC remains elusive. METHODS The expression of BMP4 and SLC2A1 were acquired by analyzing the TCGA-LIHC dataset, as well as by immunohistochemical analysis of the 40 pairs of human HCC samples and para-tumor tissues. Gene expressions were detected by qPCR, immunoflurorescence staining, and Western blotting. Overexpression and silencing of BMP4 were accomplished through adenoviruses Ad-B4 and Ad-siB4 infection. Hepatic glycogen was detected by PAS staining. SLC2A1 (GLUT1) function was blocked by the inhibitor BAY-876. ChIP assay was used to determine the binding of SMADs to the promoter region of SLC2A1 in HCC cells. Lastly, the in vivo effect of BMP4-regulated SLC2A1 on HCC tumor growth was assessed in a xenograft model of HCC. RESULTS The elevated expression of BMP4 in HCC tumor tissues was highly correlated with hepatic glycogen accumulation in clinical samples. SLC2A1 was highly expressed in HCC tumor tissue and correlated with clinical stage and prognosis. Exogenous BMP4 augmented glycogen accumulation and upregulated the expression of glycogen synthesis-related genes in Huh7 and HepG2 cells, both of which were effectively blunted by SLC2A1inhibitor BAY-876. In mechanism, BMP4 activated SMAD5 to regulate the promoter of SLC2A1to enhance its expression. The in vivo xenograft experiments revealed that BMP4 promoted glycogen accumulation and tumor growth, which were effectively diminished by BAY-876. CONCLUSION These results demonstrate that BMP4 upregulates glycogen synthesis through the SMAD/SLC2A1 (GLUT1) signaling axis in HCC cells, which may be exploited as novel therapeutic targets for HCC treatment.

Abstract
Ovarian cancer (OC) is one of the most lethal malignancies of the female reproductive system. OC patients are usually diagnosed at advanced stages due to the lack of early diagnosis. The standard treatment for OC includes a combination of debulking surgery and platinum-taxane chemotherapy, while several targeted therapies have recently been approved for maintenance treatment. The vast majority of OC patients relapse with chemoresistant tumors after an initial response. Thus, there is an unmet clinical need to develop new therapeutic agents to overcome the chemoresistance of OC. The anti-parasite agent niclosamide (NA) has been repurposed as an anti-cancer agent and exerts potent anti-cancer activities in human cancers including OC. Here, we investigated whether NA could be repurposed as a therapeutic agent to overcome cisplatin-resistant (CR) in human OC cells. To this end, we first established two CR lines SKOV3CR and OVCAR8CR that exhibit the essential biological characteristics of cisplatin resistance in human cancer. We showed that NA inhibited cell proliferation, suppressed cell migration, and induced cell apoptosis in both CR lines at a low micromole range. Mechanistically, NA inhibited multiple cancer-related pathways including AP1, ELK/SRF, HIF1, and TCF/LEF, in SKOV3CR and OVCAR8CR cells. NA was further shown to effectively inhibit xenograft tumor growth of SKOV3CR cells. Collectively, our findings strongly suggest that NA may be repurposed as an efficacious agent to combat cisplatin resistance in chemoresistant human OC, and further clinical trials are highly warranted.

Plasma levels of bone morphogenic protein-4 are downregulated in elderly hypertensive patients with heart failure with preserved ejection fraction. Clin Biochem 2023; 116:31-37. [PMID: 36935066 DOI: 10.1016/j.clinbiochem.2023.03.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2022] [Revised: 03/14/2023] [Accepted: 03/16/2023] [Indexed: 03/19/2023]
Abstract
OBJECTIVE This study aimed to evaluate the association between plasma bone morphogenic protein-4 (BMP-4) levels and heart failure (HF) with preserved ejection fraction (HFpEF) or mildly reduced ejection fraction (HFmrEF) in elderly hypertensive patients. METHODS A total of 222 hypertensive individuals meeting the inclusion criteria were enrolled from October 2021 to July 2022. Data were collected including clinical characteristics, laboratory tests and echocardiogram measurements. Plasma BMP-4 levels were tested using enzyme-linked immunosorbent assay analysis. RESULTS Among 222 elderly hypertensive patients, 149 were without HF, 59 had HFpEF, and 14 had HFmrEF. Plasma BMP-4 levels were strikingly downregulated in hypertensive patients with HFpEF/HFmrEF [median (25th, 75th percentile): 15.89 (7.69, 23.12) pg/mL vs. 19.67 (10.60, 33.04) pg/mL; P = 0.002]. After univariate and multivariate logistic regression analysis, the risk of HFpEF/HFmrEF was declined in the 4th quartile BMP-4 group when compared with the 1st quartile BMP-4 group (odds ratio, 0.20, 95% confidence interval (CI), 0.04 to 1.00; P = 0.050, P for trend = 0.025). Receiver operating characteristic curve analysis revealed that BMP-4 ≤ 28.5 pg/mL exhibited a sensitivity of 95.9% and a specificity of 28.2% in HFpEF/HFmrEF diagnosis. Furthermore, the area under the curve (AUC) was 0.619 (95% CI:0.540-0.698, P < 0.001). The corresponding AUC for brain natriuretic peptide (BNP) was 0.781 (95% CI: 0.710-0.852), P < 0.001. Adding BMP-4 to BNP increased the AUC to 0.790 (95% CI: 0.724-0.856), vs. BMP-4, P < 0.001; vs. BNP, P = 0.730, respectively. CONCLUSIONS Plasma BMP-4 levels are downregulated in elderly hypertensive patients with HFpEF. BMP-4 is a promising biomarker for diagnosing HFpEF/HFmrEF during hypertension.

Abstract
Effective and safe liver-directed gene therapy has great promise in treating a broad range of liver diseases. While adenoviral (Ad) vectors have been widely used for efficacious in vivo gene delivery, their translational utilities are severely limited due to the short duration of transgene expression and solicitation of host immune response. Used as a promising polymeric vehicle for drug release and nucleic acid delivery, carboxymethyl chitosan (CMC) is biocompatible, biodegradable, anti-microbial, inexpensive, and easy accessible. Here, by exploiting its biocompatibility, controlled release capability and anti-inflammatory activity, we investigated whether CMC can overcome the shortcomings of Ad-mediated gene delivery, hence improving the prospect of Ad applications in gene therapy. We demonstrated that in the presence of optimal concentrations of CMC, Ad-mediated transgene expression lasted up to 50 days after subcutaneous injection, and at least 7 days after intrahepatic injection. Histologic evaluation and immunohistochemical analysis revealed that CMC effectively alleviated Ad-induced host immune response. In our proof-of-principle experiment using the CCl4-induced experimental mouse model of chronic liver damage, we demonstrated that repeated intrahepatic administrations of Ad-IL10 mixed with CMC effectively mitigated the development of hepatic fibrosis. Collectively, these results indicate that CMC can improve the prospect of Ad-mediated gene therapy by diminishing the host immune response while allowing readministration and sustained transgene expression.

Transcriptome analysis reveals fluid shear stress (FSS) and atherosclerosis pathway as a candidate molecular mechanism of short-term low salinity stress tolerance in abalone. BMC Genomics 2022; 23:392. [PMID: 35606721 PMCID: PMC9128277 DOI: 10.1186/s12864-022-08611-8] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Accepted: 05/09/2022] [Indexed: 12/02/2022] Open
Abstract
Background Transcriptome sequencing is an effective tool to reveal the essential genes and pathways underlying countless biotic and abiotic stress adaptation mechanisms. Although severely challenged by diverse environmental conditions, the Pacific abalone Haliotis discus hannai remains a high-value aquaculture mollusk and a Chinese predominantly cultured abalone species. Salinity is one of such environmental factors whose fluctuation could significantly affect the abalone’s cellular and molecular immune responses and result in high mortality and reduced growth rate during prolonged exposure. Meanwhile, hybrids have shown superiority in tolerating diverse environmental stresses over their purebred counterparts and have gained admiration in the Chinese abalone aquaculture industry. The objective of this study was to investigate the molecular and cellular mechanisms of low salinity adaptation in abalone. Therefore, this study used transcriptome analysis of the gill tissues and flow cytometric analysis of hemolymph of H. discus hannai (DD) and interspecific hybrid H. discus hannai ♀ x H. fulgens ♂ (DF) during low salinity exposure. Also, the survival and growth rate of the species under various salinities were assessed. Results The transcriptome data revealed that the differentially expressed genes (DEGs) were significantly enriched on the fluid shear stress and atherosclerosis (FSS) pathway. Meanwhile, the expression profiles of some essential genes involved in this pathway suggest that abalone significantly up-regulated calmodulin-4 (CaM-4) and heat-shock protein90 (HSP90), and significantly down-regulated tumor necrosis factor (TNF), bone morphogenetic protein-4 (BMP-4), and nuclear factor kappa B (NF-kB). Also, the hybrid DF showed significantly higher and sustained expression of CaM and HSP90, significantly higher phagocytosis, significantly lower hemocyte mortality, and significantly higher survival at low salinity, suggesting a more active molecular and hemocyte-mediated immune response and a more efficient capacity to tolerate low salinity than DD. Conclusions Our study argues that the abalone CaM gene might be necessary to maintain ion equilibrium while HSP90 can offset the adverse changes caused by low salinity, thereby preventing damage to gill epithelial cells (ECs). The data reveal a potential molecular mechanism by which abalone responds to low salinity and confirms that hybridization could be a method for breeding more stress-resilient aquatic species.

Bone morphogenetic protein 4 alleviates nonalcoholic steatohepatitis by inhibiting hepatic ferroptosis. Cell Death Dis 2022; 8:234. [PMID: 35477568 PMCID: PMC9046379 DOI: 10.1038/s41420-022-01011-7] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2021] [Revised: 03/28/2022] [Accepted: 03/30/2022] [Indexed: 01/22/2023]
Abstract
Nonalcoholic steatohepatitis (NASH) is a state of simple steatosis that progresses to inflammation and liver injury accompanied by ferroptosis. Bone morphogenetic protein 4 (BMP4) plays an important role in adipogenesis and differentiation, as well as in hepatic steatosis and iron regulation. However, the direct impact of BMP4 on NASH remains unclear. In this study, our aim was to investigate the effect of BMP4 on NASH and its underlying mechanism. We first explored BMP4 expression in vivo in mice and patients and in vitro in HepG2 and LO2 cell lines, and then, determined whether ferroptosis occurs in NASH. Further overexpression or inhibition of BMP4 was induced to observe the effect of BMP4 on liver ferroptosis in NASH. BMP4 expression was upregulated in patients and mice with nonalcoholic fatty liver disease, and free fatty acid (FFA)-induced HepG2 and LO2 cell lines. We observed ferroptosis in high-fat diet and high-fructose diet-fed mice and FFA-induced HepG2 and LO2 cell lines. BMP4 overexpressing plasmid was constructed and the HepG2 and LO2 cells were transfected with lentivirus (oe-BMP4), or treated with exogenously added recombinant human BMP4 or BMP antagonist noggin. BMP4 suppressed the markers of hepatic steatosis, liver inflammation, and liver injury. Upregulated BMP4 expression in HepG2 and LO2 cells reduced reactive oxygen species and malondialdehyde content and relieved ferroptosis. Mechanistically, BMP4 overexpression in hepatocytes upregulated the mRNA and protein levels of glutathione peroxidase 4 (GPX4), a central regulator of ferroptosis, while exogenous inhibition of BMP4 by noggin decreased their levels. Immunoprecipitation assays demonstrated a physical interaction between BMP4 and GPX4 in HepG2 and LO2 cells, and confocal imaging confirmed colocalization of BMP4 and GPX4. Consistently, BMP4 overexpression plays an important role in NASH by increasing GPX4 expression, therefore decreasing hepatic ferroptosis. This study proposes BMP4 as a therapeutic target for preventing steatohepatitis.

OUHP: an optimized universal hairpin primer system for cost-effective and high-throughput RT-qPCR-based quantification of microRNA (miRNA) expression. Nucleic Acids Res 2021; 50:e22. [PMID: 34850128 PMCID: PMC8887422 DOI: 10.1093/nar/gkab1153] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/16/2021] [Revised: 11/03/2021] [Accepted: 11/08/2021] [Indexed: 12/16/2022] Open
Abstract
MicroRNAs (miRNAs or miRs) are single-stranded, ∼22-nucleotide noncoding RNAs that regulate many cellular processes. While numerous miRNA quantification technologies are available, a recent analysis of 12 commercial platforms revealed high variations in reproducibility, sensitivity, accuracy, specificity and concordance within and/or between platforms. Here, we developed a universal hairpin primer (UHP) system that negates the use of miRNA-specific hairpin primers (MsHPs) for quantitative reverse transcription PCR (RT-qPCR)-based miRNA quantification. Specifically, we analyzed four UHPs that share the same hairpin structure but are anchored with two, three, four and six degenerate nucleotides at 3'-ends (namely UHP2, UHP3, UHP4 and UHP6), and found that the four UHPs yielded robust RT products and quantified miRNAs with high efficiency. UHP-based RT-qPCR miRNA quantification was not affected by long transcripts. By analyzing 14 miRNAs, we demonstrated that UHP4 closely mimicked MsHPs in miRNA quantification. Fine-tuning experiments identified an optimized UHP (OUHP) mix with a molar composition of UHP2:UHP4:UHP6 = 8:1:1, which closely recapitulated MsHPs in miRNA quantification. Using synthetic LET7 isomiRs, we demonstrated that the OUHP-based qPCR system exhibited high specificity and sensitivity. Collectively, our results demonstrate that the OUHP system can serve as a reliable and cost-effective surrogate of MsHPs for RT-qPCR-based miRNA quantification for basic research and precision medicine.
