Abstract
Sepsis, marked by organ dysfunction, necessitates reliable biomarkers. Ribonuclease inhibitor 1 (RNH1), a ribonuclease (RNase) inhibitor, emerged as a potential biomarker for acute kidney injury and mortality in thoracoabdominal aortic aneurysm patients. Our study investigates RNH1 dynamics in sepsis, its links to mortality and organ dysfunction, and the interplay with RNase 1 and RNase 5. Furthermore, we explore RNH1 as a therapeutic target in sepsis-related processes like inflammation, non-canonical inflammasome activation, and iron homeostasis. We showed that RNH1 levels are significantly higher in deceased patients compared to sepsis survivors and correlate with creatine kinase, aspartate and alanine transaminase, bilirubin, serum creatinine and RNase 5, but not RNase 1. RNH1 mitigated LPS-induced TNFα and RNase 5 secretion, and relative mRNA expression of ferroptosis-associated genes HMOX1, FTH1 and HAMP in PBMCs. Monocytes were identified as the predominant type of LPS-positive PBMCs. Exogenous RNH1 attenuated LPS-induced CASP5 expression, while increasing IL-1β secretion in PBMCs and THP-1 macrophages. As RNH1 has contradictory effects on inflammation and non-canonical inflammasome activation, its use as a therapeutic agent is limited. However, RNH1 levels may play a central role in iron homeostasis during sepsis, supporting our clinical observations. Hence, RNH1 shows promise as biomarkers for renal and hepatic dysfunction and hepatocyte injury, and may be useful in predicting the outcome of septic patients.

Abstract
Diabetes mellitus is a common heterogeneous metabolic disorder, characterized by
deposition of extracellular matrix, oxidative stress, and vascular dysfunction,
thereby leading to gradual loss of function in multiple organs. However, little
attention has been paid to gene expression changes in the lung under
hyperglycemic conditions. In this study, we found that diabetes inuced
histological changes in the lung of streptozotocin-induced diabetic mice. Global
gene expression profiling revealed a set of genes that are up- and
down-regulated in the lung of diabetic mice. Among these, expression of
Amigo2, Adrb2, and Zbtb16 were confirmed
at the transcript level to correlate significantly with hyperglycemia in the
lung. We further evaluated the effect of human umbilical cord-derived
perivascular stem cells (PVCs) on these gene expression in the lung of diabetic
mice. Our results show that administration of PVC-conditioned medium
significantly suppressed Amig2, Adrb2, and
Zbtb16 upregulation in these mice, suggesting that these
genes may be useful indicators of lung injury during hyperglycemia. Furthermore,
PVCs offer a promising alternative cell therapy for treating diabetic
complications via regulation of gene expression.

Regulation of JAM2 Expression in the Lungs of Streptozotocin-Induced Diabetic Mice and Human Pluripotent Stem Cell-Derived Alveolar Organoids. Biomedicines 2020; 8:biomedicines8090346. [PMID: 32932992 PMCID: PMC7555027 DOI: 10.3390/biomedicines8090346] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/11/2020] [Revised: 08/30/2020] [Accepted: 09/09/2020] [Indexed: 12/26/2022] Open
Abstract
Hyperglycemia is a causative factor in the pathogenesis of respiratory diseases, known to induce fibrosis and inflammation in the lung. However, little attention has been paid to genes related to hyperglycemic-induced lung alterations and stem cell applications for therapeutic use. In this study, our microarray data revealed significantly increased levels of junctional adhesion molecule 2 (JAM2) in the high glucose (HG)-induced transcriptional profile in human perivascular cells (hPVCs). The elevated level of JAM2 in HG-treated hPVCs was transcriptionally and epigenetically reversible when HG treatment was removed. We further investigated the expression of JAM2 using in vivo and in vitro hyperglycemic models. Our results showed significant upregulation of JAM2 in the lungs of streptozotocin (STZ)-induced diabetic mice, which was greatly suppressed by the administration of conditioned medium obtained from human mesenchymal stem cell cultures. Furthermore, JAM2 was found to be significantly upregulated in human pluripotent stem cell-derived multicellular alveolar organoids by exposure to HG. Our results suggest that JAM2 may play an important role in STZ-induced lung alterations and could be a potential indicator for predicting the therapeutic effects of stem cells and drugs in diabetic lung complications.

Abstract
Atopic dermatitis (AD) is one of the most common skin diseases with inflammation, chronic relapses, and intense pruritus. Its pathogenesis includes genetic susceptibility, an abnormal epidermal lipid barrier, and an increased production of IgE due to immune dysregulation. Recently, AD has been reported to be associated with intestinal inflammation and dysbiosis in human and murine models. Various probiotics are being used to control intestinal dysbiosis and inflammatory reactions. However, it is difficult to predict or determine the therapeutic effects of the probiotics, since it is rare for clinicians to use the probiotics alone to treat AD. It is also difficult to check whether the intestinal inflammation in patients with AD has improved since probiotic treatment. The aim of the present study was to determine whether mice with induced atopic dermatitis had any changes in fecal calprotectin, an indicator of intestinal inflammation, after probiotic administration. Our results showed that the fecal calprotectin levels in mice with induced dermatitis decreased significantly after the administration of probiotics. In addition, epidermal skin lesions were attenuated and inflammatory-related cytokines were downregulated after the administration of probiotics in mice with induced dermatitis. These results suggest that changes in fecal calprotectin levels could be used to assess the effectiveness of a probiotic strain as an adjuvant treatment for AD.
