Li S, Yu J, Zhang J, Li X, Yu J. LSD1 interacting with HSP90 promotes skin wound healing by inducing metabolic reprogramming of hair follicle stem cells through the c-MYC/LDHA axis. FASEB J 2023; 37:e23031. [PMID: 37342917 DOI: 10.1096/fj.202202001rr] [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: 11/29/2022] [Revised: 05/11/2023] [Accepted: 06/02/2023] [Indexed: 06/23/2023]
Abstract
It has been demonstrated that hair follicle stem cells (HFSCs) can contribute to wound closure and repair. However, the specific mechanism remains unclear due to the complexity of the wound repair process. Lysine-specific demethylase 1 (LSD1), an important gene for the regulation of stem cell differentiation, has been reported to participate in wound healing regulation. Heat shock protein 90 (HSP90), a chaperone protein, is recently discovered to be a driver gene for wound healing. This study explored the molecular mechanisms by which the binding between LSD1 and HSP90 affects the role of HFSCs during skin wound healing. Following bioinformatics analysis, the key genes acting on HFSCs were identified. The expression of LSD1, HSP90, and c-MYC was found to be upregulated in differentiated HFSCs. Analysis of their binding affinity revealed that LSD1 interacted with HSP90 to enhance the stability of the transcription factor c-MYC. Lactate dehydrogenase A (LDHA) has been documented to be essential for HFSC activation. Therefore, we speculate that LDHA may induce the differentiation of HFSCs through glucose metabolism reprogramming. The results showed that c-MYC activated LDHA activity to promote glycolytic metabolism, proliferation, and differentiation of HFSCs. Finally, in vivo animal experiments further confirmed that LSD1 induced skin wound healing in mice via the HSP90/c-MYC/LDHA axis. From our data, we conclude that LSD1 interacting with HSP90 accelerates skin wound healing by inducing HFSC glycolytic metabolism, proliferation, and differentiation via c-MYC/LDHA axis.

[PMID: 36262781 PMCID: PMC9573845 DOI: 10.1007/s12291-021-01011-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 09/24/2021] [Indexed: 10/20/2022]
Abstract
The identification and pharmacological validation of plant-based lead compounds for the cure of different diseases including cancer have always been globally strived. In addition to possessing numerous medicinal properties, many of the phytochemicals display antioxidant potential activities. Reactive oxygen species (ROS) causeoxidative stress leading to several severe diseases such as cancer. The antioxidants are substances that fight against ROS to protect the cells from their damaging effects. In the present study, the effects of methanol extract of Euglena tuba(ETME) have been evaluated for its antioxidant and antitumor potential against Dalton's lymphoma (DL) introduced in BALB/cmice. After 24 h of intraperitoneal inoculation of DL cells in mice, ETME (300 mg kg-1 body weight) was administered intraperitoneally upto18 alternative days. On the 18th day, the mice were sacrificed; the blood and tissues (liver and brain) were collected to determine the tumor growth parameters including morphological, behavioural, haematological profile, and antioxidant indices. The results indicated that ETME exhibited significant antioxidative and antitumor properties when compared with the data from DL bearing mice. The results from the present study indicated that ETME contained remarkable antitumor efficacy, which was mediated through amelioration of oxidative stress. The data suggested that ETME could be used as a potential natural anticancer agent.

Oncol Lett 2019; 18:4858-4864. [PMID: 31611996 PMCID: PMC6781734 DOI: 10.3892/ol.2019.10813] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/08/2019] [Accepted: 08/05/2019] [Indexed: 02/06/2023] Open
Abstract
XAV939, a tankyrase inhibitor, exerts an anticancer effect in 3-dimensional (3D) cultured SW480 cells, however this is not exhibited in 2-dimensional (2D) cultured SW480 cells. In the current study, XAV939 induced a 3.7-fold increase in cellular apoptosis in 3D culture but not in the 2D culture. However, no significant changes were indicated in cell cycle distribution in the 2D or 3D culture. Based on the observation that protein expression, which was associated with the glycolytic pathway, was increased in the 3D culture, the effect of XAV939 on the patterns of glycolytic protein expression was assessed. XAV939 was revealed to decrease lactose dehydrogenase A (LDHA) expression in 3D cultured SW480 cells, but only exerted a small effect in the 2D culture. The coadministration of XAV939 with the LDHA inhibitor FX11 decreased proliferation in 3D cultured SW480 cells compared with the single administration of FX11, while there was no additive effect in the 2D culture. The lactate assay also indicated that XAV939 decreased lactate secretion in the 3D cell culture but not in the 2D culture. These results suggest that XAV939 exerts an anticancer effect through inhibition of LDHA in the 3D culture.
