(-) - Epicatechin regulates LOC107986454 by targeting the miR-143-3p/EZH2 axis to enhance the radiosensitivity of non-small cell lung cancer. Am J Med Sci 2024:S0002-9629(24)01328-4. [PMID: 38944201 DOI: 10.1016/j.amjms.2024.06.027] [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: 08/22/2023] [Revised: 04/10/2024] [Accepted: 06/24/2024] [Indexed: 07/01/2024]
Abstract
BACKGROUND AND OBJECTIVE Non-small cell lung cancer (NSCLC) is a pernicious tumor with high incidence and mortality rates. The incidence rate of NSCLC increases with age and poses a serious danger to human health. The aim of this study was to determine the mechanism by which (-)-epicatechin (EC) alleviates NSCLC. METHODS Twenty-four pairs of NSCLC tissues and cancer-adjacent tissues were collected, and A549 and H460 radiotherapy-resistant strains were generated by repeatedly irradiating A549 and H460 cells with dose-gradient X-rays. Radiotherapy-resistant H460 cells were successfully injected subcutaneously into the left dorsal side of nude mice at a dose of 1 × 105 to establish an NSCLC animal model. The levels of interrelated genes and proteins were detected by RT‒qPCR and Western blotting, and cell proliferation and apoptosis were evaluated by CCK‒8 assay, Transwell assay, flow cytometry, and TUNEL staining. RESULTS LOC107986454 was highly expressed in NSCLC patients, while miR-143-3p was expressed at low levels and was negatively correlated with LOC107986454. Functionally, EC promoted autophagy and apoptosis induced by radiotherapy, restrained cell proliferation and migration, and ultimately enhanced the radiosensitivity of NSCLC cells. A downstream mechanistic study showed that EC facilitated miR-143-3p expression by inhibiting LOC107986454 and then restraining the expression of EZH2, which ultimately facilitated autophagy and apoptosis in cancer cells, inhibited proliferation and migration, and enhanced the radiosensitivity of NSCLC cells. CONCLUSION EC can enhance the radiosensitivity of NSCLC cells by regulating the LOC107986454/miR-143-3p/EZH2 axis.

Fei H, Qian Y, Pan T, Wei Y, Hu Y. Curcumin alleviates hypertrophic scarring by inhibiting fibroblast activation and regulating tissue inflammation. J Cosmet Dermatol 2024; 23:227-235. [PMID: 37400988 DOI: 10.1111/jocd.15905] [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: 02/26/2023] [Revised: 04/12/2023] [Accepted: 06/21/2023] [Indexed: 07/05/2023]
Abstract
BACKGROUND Hypertrophic scar (HS) that can lead to defects in appearance and function is often characterized by uncontrolled fibroblast proliferation and excessive inflammation. Curcumin has been shown to have anti-inflammatory and anti-oxidative effects and to play an anti-fibrotic role by interfering transforming growth factor-β1 (TGF-β1)/Smads signaling pathways. AIM To study the effect and mechanism of curcumin on HS from the perspective of fibroblast activity and inflammation regulation. METHODS Cell proliferation, migration and the expression of α-smooth muscle actin (α-SMA) of TGF-β1-induced human dermal fibroblasts (HDFs) treated by curcumin were evaluated using Cell Counting Kit-8 assay, 5-ethynyl-2'-deoxyuridine staining, Transwell assay, Western blotting and immunofluorescence, respectively. The expression of TGF-β1/Smad3 pathway-related molecules (TGF-β1, TGFβ-R1/2, p-Smad3, Smad4) was detected by Western blotting. In a rabbit ear model, hematoxylin and eosin and Masson's staining were conducted to assess scar elevation and collagen deposition, and immunohistochemistry was performed to detect the activation of fibroblasts and infiltration of inflammatory cells. RESULTS Curcumin inhibited proliferation, migration and α-SMA expression of HDFs in a dose-dependent manner. Curcumin (25 μm mol/L) did not regulate the expression of endogenous TGF-β1, but suppressed Smad3 phosphorylation and nuclear translocation, leading to lower α-SMA expression. Curcumin also reduced hypertrophic scarring of rabbit ear, accompanied by the inhibited TGF-β1/Smad3 pathway, inflammatory infiltration and M2 macrophage polarization. CONCLUSION Curcumin plays an anti-scar role through regulating fibroblast activation and tissue inflammation. Our findings provide scientific reference for the clinical use of curcumin in the treatment of HS.

A multifunctional surgical suture with electroactivity assisted by oligochitosan/gelatin-tannic acid for promoting skin wound healing and controlling scar proliferation. Carbohydr Polym 2023; 320:121236. [PMID: 37659821 DOI: 10.1016/j.carbpol.2023.121236] [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: 05/11/2023] [Revised: 07/23/2023] [Accepted: 07/25/2023] [Indexed: 09/04/2023]
Abstract
Surgical wound closure is accomplished most frequently with sutures, optimally proceeding rapidly and without complication. However, surgical sutures can trigger foreign body reactions and incite abnormal collagen deposition. Sustained inflammation can result in abnormal wound healing with hypertrophic scar formation. Therefore, evolution of suture material to inhibit inflammation and scar formation is of great clinical significance. In the present study, commercial 3-0 PPDO [poly(p-dioxanone)] suture was used as the base material and modified by adding two layers: a drug-loaded layer and an electroactive layer. The former layer was curcumin (Cur) encapsulated by PLGA [poly (lactic-co-glycolic acid)] and the latter layer was composed of oligochitosan-gelatin/tannic acid/polypyrrole (OCS-GE/TA/PPy). The multifunctional sutures, named S@LC@CGTP, had desirable sustained-drug release properties in vitro where Cur could be released for 8 days due to the action of PLGA. The three-dimensional network structure of OCS-GE/TA ensured S@LC@CGTP against surface cracking and maintained electrical. Furthermore, using an in vivo experiment, S@LC@CGTP could attenuate inflammation and promote scar-free wound healing according to suppression of infiltrating inflammatory cells, down-regulation of TGF-β1 and collagen type I expression, and improved collagen arrangement. Cumulatively, we indicated that S@LC@CGTP suture material has great potential to facilitate optimal, nearly scarless healing of surgical incisions.

Abstract
BACKGROUND Resveratrol (RSV) exerts anti-fibrotic effects on various fibrotic diseases. Whereas the biological role of RSV on urethral fibrosis remains to be elucidated. This study aimed to determine the mechanisms by which RSV affects urethral fibrosis and autophagy. METHODS Sprague‒Dawley rats and primary fibroblasts were treated with transforming growth factor-β1 (TGFβ1) to generate in vivo and in vitro fibrosis models. Then, those were treated with RSV, and autophagy and fibrosis-related indicators were tested. RESULTS Firstly, we found that RSV reversed the upregulation of indicators related to TGFβ1-induced fibrosis (TGFβ1, α-smooth muscle actin, collagen type I, and collagen type III), autophagy (TFEB and LC3), and TGFβR1/Smad4 pathway, as well as the downregulation of p62 and miR-192-5p expression both in vivo and in vitro. Overexpression of miR-192-5p suppressed the upregulation of fibrosis-related markers expression, as well as TFEB and LC3 expression, induced by TGFβ1, while the expression trend of p62 was the opposite. Inhibiting miR-192-5p reversed the effects of RSV on the model group cells. It was also shown that RSV combined with sh-Smad4 inhibited autophagy more effectively than RSV alone. CONCLUSION These results suggest that RSV inhibits urinary fibrosis and autophagy via the miR-192-5p/TGFβR1/Smad4 pathway. RAV may be a potential drug for alleviating urethral fibrosis.

J Tissue Eng Regen Med 2022; 16:836-849. [PMID: 35716353 DOI: 10.1002/term.3334] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2022] [Revised: 05/16/2022] [Accepted: 05/31/2022] [Indexed: 02/05/2023]
Abstract
Male erectile dysfunction (ED) caused by cavernous nerve injury is a common complication of pelvic surgery, radiotherapy, transurethral surgery or other operations. However, clinical treatment for iatrogenic or traumatic male ED is difficult and not satisfactory. Many studies have shown that curcumin can promote the repair and regeneration of peripheral nerves; however, whether curcumin can rescue cavernous nerve injury is unknown, and the poor bioavailability of curcumin limits its application in vivo. Hence, the study was conducted. A curved slow-release membrane was produced, and the properties were examined. In addition, the effects of the curcumin slow-release membrane on cavernous nerve-injured SD rats were studied. We found that polylactic acid-glycolic acid-polyethylene glycol (PLGA-PEG) can be used as a good carrier material for curcumin, and curcumin-loaded PLGA-PEG membranes can effectively rescue the cavernous nerve in SD rats, restore the continuity of the cavernous nerve, and increase the expression of nNOS mRNA and proteins in penile tissue, which can improve the penile erectile function of injured SD rats, reduce the degree of penile tissue fibrosis, and effectively promote penis rehabilitation. The curcumin slow-release membrane is proposed to be a new therapeutic approach for penile rehabilitation of cavernous nerve injury.

Abstract
Objective To study the radiosensitization effect of curcumin, a natural product with
anti-inflammatory and anti-cancer properties, in bladder cancer cells and identify the
specific role of FLNA gene in that process. Methods CCK-8 method was initially adopted to identify the proper interventional concentration
of curcumin. T24 bladder cancer cells were subjected to CCK-8, flow cytometry, and
colony formation assay to study the cell biological behaviors under different
interventions. γ-H2AX test was performed to test the level of damage in T24 cells.
RT-qPCR and Western blot were conducted to measure FLNA mRNA and protein levels. Results Low-dose curcumin (10, 20 μM) following X-ray exposure resulted in increased DNA
damage, augmented apoptosis, and reduced proliferation of T24 cells. Certain
radiosensitization was demonstrated when curcumin was applied at 10 μM. Additionally,
elevation of FLNA gene and protein levels was also indicated upon combination
treatment. Conclusion Low-dose curcumin has certain radiosensitization effect in bladder cancer, where FLNA
plays a certain regulatory role.
