Biomed Pharmacother 2023; 169:115896. [PMID: 37984305 DOI: 10.1016/j.biopha.2023.115896] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Revised: 11/08/2023] [Accepted: 11/13/2023] [Indexed: 11/22/2023] Open
Abstract
Acute lung injury (ALI) is a progressive inflammatory injury, and mesenchymal stem cells (MSCs) can be used to treat ALI. MSC-conditioned medium (MSC-CM) contains many cytokines, in which keratinocyte growth factor (KGF) is a soluble factor that plays a role in lung development. We aim to explore the protective effects of MSCs secreted KGF on ALI, and investigate the involvement of epithelial sodium channel (ENaC), which are important in alveolar fluid reabsorption. Both lipopolysaccharides (LPS)-induced mouse and alveolar organoid ALI models were established to confirm the potential therapeutic effect of MSCs secreted KGF. Meanwhile, the expression and regulation of ENaC were determined in alveolar type II epithelial (ATII) cells. The results demonstrated that MSC-CM and KGF could alleviate the extent of inflammation-related pulmonary edema in ALI mice, which was abrogated by a KGF neutralizing antibody. In an alveolar organoid ALI model, KGF in MSC-CM could improve the proliferation and decrease the differentiation of ATII cells. At the cellular level, the LPS-inhibited protein expression of ENaC could be reversed by KGF in MSC-CM. In addition, bioinformatics analysis and our experimental data provided the evidence that the NF-κB signaling pathway may be involved in the regulation of ENaC. Our research confirmed that the therapeutic effect of MSC-CM on edematous ALI was closely related to KGF, which may be involved in the proliferation and differentiation of ATII cells, as well as the upregulation of ENaC expression by the inhibition of NF-κB signaling pathway.

Abstract
BACKGROUND Seborrheic dermatitis is a common chronic inflammatory skin disorder that affects the scalp and is characterized by erythema and oily scales. It could perhaps be difficult to control and could seriously degrade one's quality of life. The study's objective is to assess the effectiveness of intradermal administrations of QR678 Neo® hair growth factor therapy for the treatment of scalp seborrheic dermatitis in both men and women. METHOD Forty male and female patients with clinically diagnosed seborrheic dermatitis of the scalp in the age 18-45 years, not satisfactorily responding to standard therapy for at least 6 months, were included. 1 mL solution of QR678 Neo® was administered in the scalp skin of all patients at 3-week interval till eight sessions. Patients were advised to continue with antifungal shampoo and topical antifungal solution with steroid combination which they had been on during the treatment. Assessment of disease severity, dermoscopic evaluation, and self-assessment were done at baseline and at the end of the fourth and the eighth sessions. RESULTS Improvement was observed in adherent scalp flaking score after eighth session (mean = 12) compared to baseline (mean = 60). The dermoscopic evaluation showed a noticeable difference from baseline (mean = 11) in erythema and scaling with the Seborrheic Dermatitis Scalp Severity Index tool at the end of treatment (mean = 2). A high satisfaction score was given for the efficiency in the self-assessment questionnaire. CONCLUSION Our study proved that treatment with QR678 Neo® led to an improvement in the overall scalp condition by the resolution of flaking and inflammation.

Abstract
Vanadium exposure has the adverse effect on lung function in human, whereas the detailed mechanisms of vanadium exposure-induced pulmonary toxicity are limited. Hence, the present study aimed to investigate the hub genes and signaling pathways related to sodium metavanadate (SMV)-induced pulmonary toxicity. The transcript expression profile GSE36684 downloaded from Gene Expression Omnibus contained eight human bronchial epithelial cell (HBEC) samples including five SMV-treated and three control HBEC samples. Totally 455 differentially expressed genes (DEGs) were screened, especially 201 and 254 genes were up- and down-regulated in the HBECs treated with SMV. Gene ontology analysis suggested that the DEGs were mainly involved in signal transduction, the response to drug, cell proliferation, adhesion, and migration. Pathway analysis demonstrated that the DEGs were primarily participated in NF-κB, Wnt, MAPK, and PI3K-Akt signaling pathways. Moreover, the hub genes, including ITGA5, ITGB3, ITGA2, LAMC2, MMP2, and ITGA4, might contribute to SMV-induced pulmonary toxicity. Our study improves the understanding of the molecular mechanisms by which SMV induced the pulmonary toxicity.

Abstract
The fibroblast growth factor (FGF) family is composed of 18 secreted signaling proteins consisting of canonical FGFs and endocrine FGFs that activate four receptor tyrosine kinases (FGFRs 1-4) and four intracellular proteins (intracellular FGFs or iFGFs) that primarily function to regulate the activity of voltage-gated sodium channels and other molecules. The canonical FGFs, endocrine FGFs, and iFGFs have been reviewed extensively by us and others. In this review, we briefly summarize past reviews and then focus on new developments in the FGF field since our last review in 2015. Some of the highlights in the past 6 years include the use of optogenetic tools, viral vectors, and inducible transgenes to experimentally modulate FGF signaling, the clinical use of small molecule FGFR inhibitors, an expanded understanding of endocrine FGF signaling, functions for FGF signaling in stem cell pluripotency and differentiation, roles for FGF signaling in tissue homeostasis and regeneration, a continuing elaboration of mechanisms of FGF signaling in development, and an expanding appreciation of roles for FGF signaling in neuropsychiatric diseases.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2022; 2022:3055039.

Abstract
Lung ischemia-reperfusion injury (LIRI), which has a mortality rate of approximately 50%, is a popular topic in critical care research. Keratinocyte growth factor-2 (KGF-2) is secreted by mesenchymal cells, and it is effective in promoting the proliferation, migration, and differentiation of various epithelial cells. To date, however, only a few reports on KGF-2-related regulators in LIRI have been published. In the current study, an LIRI rat model is constructed, and the upregulation of the fibroblast growth factor receptor 2 (FGFR2) is observed in the LIRI rat model. In addition, LIRI induces NLRP1 inflammasome activation in vivo and in vitro, and KGF-2 inhibits LIRI-induced damage to pulmonary microvascular endothelial cells. Mechanistically, KGF-2 inhibits NLRP1 inflammasome and NF-κB activity. KGF-2 inhibition attenuates LIRI injury-induced damage to endothelial integrity. In conclusion, KGF-2 protects against LIRI by inhibiting inflammation-induced endothelial barrier damage.

Abstract
BACKGROUND Alveolar macrophages (AMs) play a demonstrative role in acute lung injury (ALI). Exosomes act as signaling molecules to regulate cell-to-cell communication by releasing RNAs. Transfer RNA-derived fragments (tRFs) possess potential functions in multiple diseases through ferroptosis. The present study aims to reveal the role of AM-derived exosomal tRFs in ALI and to identify the relationship to ferroptosis. METHODS ALI mice model was established by lipopolysaccharide (LPS) induction. RNA sequencing was performed to identify the tRFs profile in bronchoalveolar lavage fluid (BALF) exosomes of ALI mice. After interfering with the expression of candidate tRFs in AMs or alveolar epithelial cells (MLE-12), the effect of oxidative stress and expression of ferroptosis-related proteins were detected. RESULTS Exosomes isolated from BALF of ALI mice were dominated by a macrophage immunophenotype. RNA-sequencing identified 4 up- and 10 down-regulated differentially expressed tRFs (DEtRFs), among which tRF-22-8BWS7K092 expression was significantly increased in LPS-induced macrophage-derived exosomes (LPS-exo). Hippo signaling pathway was the most significantly enriched KEGG pathways for DEtRFs. LPS-exo inhibited cell viability and the expression of GPX4 and FTH1, and enhanced oxidative stress in MLE-12 cells. Ferroptosis inhibitor reversed the inhibition of LPS-exo on cell viability and tRF-22-8BWS7K092 inhibitor rescued above effect of LPS-exo on MLE-12 cells. Besides, tRF-22-8BWS7K092 could activate Hippo signaling pathway by binding Wnt5B, inducing ferroptosis in MLE-12 cells. CONCLUSION BALF exosomes of ALI mice were mainly derived from AMs. AM-derived exosomal tRF-22-8BWS7K092 activates the Hippo signaling pathway to induce ferroptosis, thus contributing to the pathogenesis of ALI.

OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2021; 2021:8889408.

Abstract
Amiodarone (AM) is one of the most effective antiarrhythmic drugs and normally administrated by intravenous infusion which is liable to cause serious phlebitis. The therapeutic drugs for preventing this complication are limited. Intermedin (IMD), a member of calcitonin family, has a broad spectrum of biological effects including anti-inflammatory effects, antioxidant activities, and antiapoptosis. But now, the protective effects of IMD against amiodarone-induced phlebitis and the underlying molecular mechanism are not well understood. In this study, the aim was to investigate the protective efficiency and potential mechanisms of IMD in amiodarone-induced phlebitis. The results of this study revealed that treatment with IMD obviously attenuated apoptosis and exfoliation of vascular endothelial cells and infiltration of inflammatory cells in the rabbit model of phlebitis induced by intravenous infusion of amiodarone compared with control. Further tests in vitro demonstrated that IMD lessened amiodarone-induced endothelial cell apoptosis, improved amiodarone-induced oxidative stress injury, reduced inflammatory reaction, and activated the Wnt/β-catenin signal pathway which was inhibited by amiodarone. And these effects could be reversed by Wnt/β-catenin inhibitor IWR-1-endo, and si-RNA knocked down the gene of Wnt pathway. These results suggested that IMD exerted the protective effects against amiodarone-induced endothelial injury via activating the Wnt/β-catenin pathway. Thus, IMD could be used as a potential agent for the treatment of phlebitis.

Dexmedetomidine preconditioning ameliorates lung injury induced by pulmonary ischemia/reperfusion by upregulating promoter histone H3K4me3 modification of KGF-2. Exp Cell Res 2021; 406:112762.

Abstract
Keratinocyte growth factor (KGF)-2 has been highlighted to play a significant role in maintaining the endothelial barrier integrity in lung injury induced by ischemia-reperfusion (I/R). However, the underlying mechanism remains largely unknown. The aims of this study were to determine whether dexmedetomidine preconditioning (DexP) modulates pulmonary I/R-induced lung injury through the alteration in KGF-2 expression. In our I/R-modeled mice, DexP significantly inhibited pathological injury, inflammatory response, and inflammatory cell infiltration, while promoted endothelial barrier integrity and KGF-2 promoter activity in lung tissues. Bioinformatics prediction and ChIP-seq revealed that I/R significantly diminished the level of H3K4me3 modification in the KGF-2 promoter, which was significantly reversed by DexP. Moreover, DexP inhibited the expression of histone demethylase JMJD3, which in turn promoted the expression of KGF-2. In addition, overexpression of JMJD3 weakened the protective effect of DexP on lung injury in mice with I/R. Collectively, the present results demonstrated that DexP ameliorates endothelial barrier dysfunction via the JMJD3/KGF-2 axis.
