Abstract
OBJECTIVE Non-alcoholic fatty liver disease (NAFLD) is a clinicopathological syndrome characterized by excessive fat deposition in hepatocytes caused by non-alcoholic liver injury. Porphyromonas gingivalis (P.g) is the main pathogen causing periodontitis, which can aggravate the progression of NAFLD in our previously study. The objective of this study was to further investigate the pathogenesis and moleculer michanisma of NAFLD aggravated by P.g. METHODS A mouse model of NAFLD was established, and the changes of inflammatory factors and NF-κB signaling pathway in liver tissue and L-02 cells were analyzed by transcriptome sequencing, Western blot, IHC and RT-PCR. In addition, the NF-κB signaling pathway inhibitor QNZ and ferroptosis inhibitor Fer-1 were used to analyze the relationship between NF-κB signaling pathway and ferroptosis in vitro. RESULTS In vivo and in vitro experiments, P.g can induce liver inflammation and activate NF-κB signaling pathway. At the same time, P.g promotes ferroptosis and inflammation in L-02 in vitro. QNZ alleviates ferroptosis and inflammatory activation in L-02. Fer-1 can relieve the L-02 inflammation caused by P.g products. CONCLUSION Porphyromonas gingivalis can induce ferroptosis and inflammation in hepatocytes and further worsen liver lesions. The mechanism of ferroptosis in hepatocytes depends on NF-κB signaling pathway, which provides a new strategy for clinical treatment and prevention of NAFLD.

Abstract
ABSTRACT Recent research has revealed that aerobic glycolysis has a strong correlation with sepsis-associated pulmonary fibrosis (PF). However, at present, the mechanism and pathogenesis remain unclear. We aimed to test the hypothesis that the adenosine monophosphate-activated protein kinase (AMPK) activation and suppression of hypoxia-inducible factor 1α (HIF-1α)-induced aerobic glycolysis play a central role in septic pulmonary fibrogenesis. Cellular experiments demonstrated that lipopolysaccharide increased fibroblast activation through AMPK inactivation, HIF-1α induction, alongside an augmentation of aerobic glycolysis. By contrast, the effects were reversed by AMPK activation or HIF-1α inhibition. In addition, pretreatment with metformin, which is an AMPK activator, suppresses HIF-1α expression and alleviates PF associated with sepsis, which is caused by aerobic glycolysis, in mice. Hypoxia-inducible factor 1α knockdown demonstrated similar protective effects in vivo . Our research implies that targeting AMPK activation and HIF-1α-induced aerobic glycolysis with metformin might be a practical and useful therapeutic alternative for sepsis-associated PF.

Abstract
Our previous studies using rodent models have suggested an essential role for Pin1 in the pathogenesis of non-alcoholic steatohepatitis (NASH). In addition, interestingly, serum Pin1 elevation has been reported in NASH patients. However, no studies have as yet examined the Pin1 expression level in human NASH livers. To clarify this issue, we investigated the expression level and subcellular distribution of Pin1 in liver specimens obtained using needle-biopsy samples from patients with NASH and healthy liver donors. Immunostaining using anti-Pin1 antibody revealed the Pin1 expression level to be significantly higher, particularly in nuclei, in the livers of NASH patients than those of healthy donors. In the samples from patients with NASH, the amount of nuclear Pin1 was revealed to be negatively related to serum alanine aminotransferase (ALT), while tendencies to be associated with other serum parameters such as aspartate aminotransferase (AST) and platelet number were noted but did not reach statistical significance. Such unclear results and the lack of a significant relationship might well be attributable to our small number of NASH liver samples (n = 8). Moreover, in vitro, it was shown that addition of free fatty acids to medium induced lipid accumulation in human hepatoma HepG2 and Huh7 cells, accompanied with marked increases in nuclear Peptidyl-prolyl cis-trans isomerase NIMA-interacting 1 (Pin1), in accordance with the aforementioned observations in human NASH livers. In contrast, suppression of Pin1 gene expression using siRNAs attenuated the free fatty acid-induced lipid accumulation in Huh7 cells. Taken together, these observations strongly suggest that increased expression of Pin1, particularly in hepatic nuclei, contributes to the pathogenesis of NASH with lipid accumulation.

Abstract
Peptidyl-prolyl isomerase (PPIase) is a unique enzyme that promotes cis-trans isomerization of a proline residue of a target protein. Peptidyl-prolyl cis-trans isomerase NIMA (never in mitosis A)-interacting 1 (Pin1) is a PPIase that binds to the pSer/pThr-Pro motif of target proteins and isomerizes their prolines. Pin1 has been reported to be involved in cancer development, obesity, aging, and Alzheimer's disease and has been shown to promote the growth of several viruses including SARS-CoV-2. Pin1 enhances the efficiency of viral infection by promoting uncoating and integration of the human immunodeficiency virus. It has also been shown that Pin1 interacts with hepatitis B virus proteins and participates in viral replication. Furthermore, Pin1 promotes not only viral proliferation but also the progression of virus-induced tumorigenesis. In this review, we focus on the effects of Pin1 on the proliferation of various viruses and discuss the underlying molecular mechanisms.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is strongly associated with type 2 diabetes mellitus (T2DM). Sesquiterpene glycosides from loquat leaf achieved beneficial effects on metabolic syndromes such as NAFLD and diabetes; however, their specific activity and underlying mechanism on T2DM-associated NAFLD have not yet been fully understood. In the present study, we found that sesquiterpene glycoside 3 (SG3), a novel sesquiterpene glycoside isolated from loquat leaf, was able to prevent insulin resistance (IR), oxidative stress, and inflammation. In db/db mice, SG3 administration (25 and 50 mg/kg/day) inhibited obesity, hyperglycemia, and the release of inflammatory cytokines. SG3 (5 and 10 μM) also significantly alleviated hepatic lipid accumulation, oxidative stress, and inflammatory response induced by high glucose combined with oleic acid in HepG2 cells. Western blotting analysis showed that these effects were related to repair the abnormal insulin signaling and inhibit the cytochrome P450 2E1 (CYP2E1) and NOD-like receptor family pyrin domain-containing 3 (NLRP3), both in vivo and in vitro. In addition, SG3 treatment could decrease the ratio of Firmicutes/Bacteroidetes and increase the relative abundance of Lachnospiraceae, Muribaculaceae, and Lactobacillaceae after a high-throughput pyrosequencing of 16S rRNA to observe the changes of related gut microbial composition in db/db mice. These findings proved that SG3 could protect against NAFLD in T2DM by improving IR, oxidative stress, inflammation through regulating insulin signaling and inhibiting CYP2E1/NLRP3 pathways, and remodeling the mouse gut microbiome. It is suggested that SG3 could be considered as a new functional additive for a healthy diet.

Abstract
Background: Hepatitis C virus (HCV) may remain asymptomatic or cause liver fibrosis and cirrhosis. Objectives: We aimed to assess the relationship between serum peptidyl-prolyl cis-trans isomerase NIMA-interacted 1 (Pin1) levels and liver fibrosis due to HCV. Methods: Serum samples of successive patients with HCV genotype 1b and healthy volunteers were collected, and Pin1 levels were measured using ELISA kits. Liver fibrosis stages were calculated by the Ishak Scoring System and subdivided into two groups; stage < 3 (mild fibrosis) and ≥ 3 (advanced fibrosis). Correlation and area under receiver operating characteristics (AUROC) analysis were used to investigate the relationship between Pin1 and clinical and histopathological properties of HCV infection. Results: Ninety-four patients with HCV and 47 age- and sex-matched volunteers were included. The median age of the participants was 52, and 55% of whom were females. The mean (SD) of Pin1 serum level was significantly higher in the HCV group compared with healthy volunteers (33.94 (21.15) vs. 26.82 (8.85) pg/mL, respectively, P = 0.007). Seventy-seven (82%) and 17 (18%) of the participants showed mild and advanced fibrosis, respectively. Pin1 serum levels were significantly lower in the mild compared with advanced fibrosis group (29 (17.88) vs. 43.59 (7.98) pg/mL, respectively, P < 0.001). We found a significantly positive correlation between Pin1 serum level and liver fibrosis stage (r = 0.71, P < 0.001). The cut off of 33.04 pg/mL of Pin1 serum level showed the best sensitivity (100%) and specificity (68.4%) (AUROC = 0.81 [95% confidence interval: 0.72 - 0.90], P < 0.001) for distinguishing advanced from mild liver fibrosis. Conclusions: Serum Pin1 level may be a relevant marker for predicting liver fibrosis in HCV infected patients.

BAFF signaling drives interstitial transformation of mouse renal tubular epithelial cells in a Pin1-dependent manner. In Vitro Cell Dev Biol Anim 2021; 57:649-659. [PMID: 34128158 PMCID: PMC8316171 DOI: 10.1007/s11626-021-00598-y] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2021] [Accepted: 05/26/2021] [Indexed: 11/23/2022]
Abstract
Aberrant expression of B cell–activating factor belonging to TNF superfamily (BAFF) and its receptors results in abnormal biological activities in hematopoietic and non-hematopoietic cells and is closely associated with the occurrence and development of various diseases. However, the biological significance and potential mechanisms underlying BAFF signaling in renal tubular epithelial cells (RTECs) remain unknown. This study aimed to investigate the biological role of BAFF signaling in RTECs. Mice primary RTECs were applied. The proliferation status and apoptotic rates were examined by MTS assay and flow cytometry, respectively. The expression of BAFF and its receptors was analyzed via flow cytometry and sodium ion transport function, and cytokeratin-18 expression was detected through immunofluorescence staining. In addition, Pin1 was knocked down via siRNA and its expression was assessed through reverse transcription PCR. Lastly, western blotting was performed to analyze E-cadherin, ɑ-SMA, and Pin1 expression. Results suggested that BAFF-R was significantly upregulated upon IFN-γ stimulation, and enhancement of BAFF signaling promoted cell survival and reduced their apoptotic rate, while simultaneously reducing the epithelial phenotype and promoting the interstitial transformation of cells. Furthermore, Pin1 was significantly increased, along with the upregulation of BAFF signaling in the RTECs, and participated in interstitial transformation induced by BAFF signaling. Collectively, the present results elucidate the potential mechanism of loss of normal function of RTECs under long-term high dose of BAFF stimulation provides a potential therapeutic target for renal interstitial fibrosis, and underlining mechanisms of shortening of long-term outcomes of kidney allografts via augmenting of BAFF signaling.

Abstract
Pin1 is the only known peptidyl-prolyl cis-trans isomerase (PPIase) that can specifically recognize and isomerize the phosphorylated Serine/Threonine-Proline (pSer/Thr-Pro) motif, change the conformation of proteins through protein phosphorylation, thus regulate various cellular processes in the body. Pin1 plays an important role in cancer, Alzheimer’s disease, and autoimmune diseases. However, the specific mechanism of Pin1 regulation in LPS-induced septic shock is unclear. Here, we found that lack of Pin1 reduced shock mortality and organ damage in mice, and NLRP3 inflammasome activation also was reduced in this process. We further confirmed that Pin1 can affect the expression of NLRP3, ASC, Caspase1, and this process can be regulated through the p38 MAPK pathway. We analyzed that p38 MAPK signaling pathway was highly expressed in septic shock and showed a positive correlation with Pin1 in the Gene Expression Omnibus database. We found that Pin1 could affect the phosphorylation of p38 MAPK, have no obvious difference in extracellular signal-regulated kinases (ERK) and Jun-amino-terminal kinase (JNK) signaling. We further found that Pin1 and p-p38 MAPK interacted, but not directly. In addition, Pin1 deficiency inhibited the cleavage of gasdermin D (GSDMD) and promoted the death of macrophages with LPS treatment, and reduced secretion of inflammatory cytokines including IL-1β and IL-18. In general, our results suggest that Pin1 regulates the NLRP3 inflammasome activation by p38 MAPK signaling pathway in macrophages. Thus, Pin1 may be a potential target for the treatment of inflammatory diseases such as septic shock.
