Aldehyde dehydrogenases contribute to skeletal muscle homeostasis in healthy, aging, and Duchenne muscular dystrophy patients. J Cachexia Sarcopenia Muscle 2020; 11:1047-1069. [PMID: 32157826 PMCID: PMC7432589 DOI: 10.1002/jcsm.12557] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/24/2019] [Revised: 12/12/2019] [Accepted: 01/30/2020] [Indexed: 12/18/2022] Open
Abstract
BACKGROUND Aldehyde dehydrogenases (ALDHs) are key players in cell survival, protection, and differentiation via the metabolism and detoxification of aldehydes. ALDH activity is also a marker of stem cells. The skeletal muscle contains populations of ALDH-positive cells amenable to use in cell therapy, whose distribution, persistence in aging, and modifications in myopathic context have not been investigated yet. METHODS The Aldefluor® (ALDEF) reagent was used to assess the ALDH activity of muscle cell populations, whose phenotypic characterizations were deepened by flow cytometry. The nature of ALDH isoenzymes expressed by the muscle cell populations was identified in complementary ways by flow cytometry, immunohistology, and real-time PCR ex vivo and in vitro. These populations were compared in healthy, aging, or Duchenne muscular dystrophy (DMD) patients, healthy non-human primates, and Golden Retriever dogs (healthy vs. muscular dystrophic model, Golden retriever muscular dystrophy [GRMD]). RESULTS ALDEF+ cells persisted through muscle aging in humans and were equally represented in several anatomical localizations in healthy non-human primates. ALDEF+ cells were increased in dystrophic individuals in humans (nine patients with DMD vs. five controls: 14.9 ± 1.63% vs. 3.6 ± 0.39%, P = 0.0002) and dogs (three GRMD dogs vs. three controls: 10.9 ± 2.54% vs. 3.7 ± 0.45%, P = 0.049). In DMD patients, such increase was due to the adipogenic ALDEF+ /CD34+ populations (11.74 ± 1.5 vs. 2.8 ± 0.4, P = 0.0003), while in GRMD dogs, it was due to the myogenic ALDEF+ /CD34- cells (3.6 ± 0.6% vs. 1.03 ± 0.23%, P = 0.0165). Phenotypic characterization associated the ALDEF+ /CD34- cells with CD9, CD36, CD49a, CD49c, CD49f, CD106, CD146, and CD184, some being associated with myogenic capacities. Cytological and histological analyses distinguished several ALDH isoenzymes (ALDH1A1, 1A2, 1A3, 1B1, 1L1, 2, 3A1, 3A2, 3B1, 3B2, 4A1, 7A1, 8A1, and 9A1) expressed by different cell populations in the skeletal muscle tissue belonging to multinucleated fibres, or myogenic, endothelial, interstitial, and neural lineages, designing them as potential new markers of cell type or of metabolic activity. Important modifications were noted in isoenzyme expression between healthy and DMD muscle tissues. The level of gene expression of some isoenzymes (ALDH1A1, 1A3, 1B1, 2, 3A2, 7A1, 8A1, and 9A1) suggested their specific involvement in muscle stability or regeneration in situ or in vitro. CONCLUSIONS This study unveils the importance of the ALDH family of isoenzymes in the skeletal muscle physiology and homeostasis, suggesting their roles in tissue remodelling in the context of muscular dystrophies.

Abstract
Therapies designed to target cancer stem cells (CSCs) in colorectal cancer (CRC) may improve treatment outcomes. Different markers have been used to identify CSCs or CSC-like cells in CRC, but the enrichment of CSCs using these markers has yet to be optimized. We recently reported the importance of Lgr5-positive CRC cells in cancer growth. Here, we studied the possibility of using Lgr5 and CXCR4 as CSC markers for CRC. We detected high Lgr5 and CXCR4 levels in stage IV CRC specimens. Both high Lgr5 and CXCR4 levels were associated with poor prognosis in stage IV CRC patients. In vitro, Lgr5+CXCR4-, CXCR4+Lgr5- and Lgr5+CXCR4+ cells were purified in human CRC cell lines and examined for their CSC properties. We found that compared to the unsorted cells, CXCR4+Lgr5-, Lgr5+CXCR4-, and Lgr5+/CXCR4+ cells showed significantly greater cancer mass after subcutaneous transplantation, greater tumor sphere formation, higher resistance to chemotherapy, and higher incidence of tumor formation after serial adoptive transplantation into NOD/SCID mice. Taken together, our data suggest that the combined use of Lgr5 and CXCR4 may facilitate the enrichment of CSCs in CRC, and that treating Lgr5+/CXCR4+ CRC cells may improve the outcome of CRC therapy.

Aldehyde dehydrogenase 3A1 promotes multi-modality resistance and alters gene expression profile in human breast adenocarcinoma MCF-7 cells. Int J Biochem Cell Biol 2016; 77:120-128. [PMID: 27276244 DOI: 10.1016/j.biocel.2016.06.004] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2015] [Revised: 03/21/2016] [Accepted: 06/03/2016] [Indexed: 12/20/2022]
Abstract
Aldehyde dehydrogenases participate in a variety of cellular homeostatic mechanisms like metabolism, proliferation, differentiation, apoptosis, whereas recently, they have been implicated in normal and cancer cell stemness. We explored roles for ALDH3A1 in conferring resistance to chemotherapeutics/radiation/oxidative stress and whether ectopic overexpression of ALDH3A1 could lead to alterations of gene expression profile associated with cancer stem cell-like phenotype. MCF-7 cells were stably transfected either with an empty vector (mock) or human aldehyde dehydrogenase 3A1 cDNA. The expression of aldehyde dehydrogenase 3A1 in MCF-7 cells was associated with altered cell proliferation rate and enhanced cell resistance against various chemotherapeutic drugs (4-hydroxyperoxycyclophosphamide, doxorubicin, etoposide, and 5-fluorouracil). Aldehyde dehydrogenase 3A1 expression also led to increased tolerance of MCF-7 cells to gamma radiation and hydrogen peroxide-induced stress. Furthermore, aldehyde dehydrogenase 3A1-expressing MCF-7 cells exhibited gene up-regulation of cyclins A, B1, B2, and down-regulation of cyclin D1 as well as transcription factors p21, CXR4, Notch1, SOX2, SOX4, OCT4, and JAG1. When compared to mock cells, no changes were observed in mRNA levels of ABCA2 and ABCB1 protein pumps with only a minor decrease of the ABCG2 pump in the aldehyde dehydrogenase 3A1-expressing cells. Also, the adhesion molecules EpCAM and CD49F were also found to be up-regulated in aldehyde dehydrogenase 3A1expressing cells. Taken together, ALDH3A1 confers a multi-modality resistance phenotype in MCF-7 cells associated with slower growth rate, increased clonogenic capacity, and altered gene expression profile, underlining its significance in cell homeostasis.

Abstract
Islet transplantation is an effective therapy for severe diabetes. Nevertheless, the short supply of donor pancreases constitutes a formidable obstacle to its extensive clinical application. This shortage heightens the need for alternative sources of insulin-producing beta cells. Since mature beta cells have a very slow proliferation rate, which further declines with age, great efforts have been made to identify beta cell progenitors in the adult pancreas. However, the question whether facultative beta cell progenitors indeed exist in the adult pancreas remains largely unresolved. In the current review, we discuss the problems in past studies and review the milestone studies and recent publications.

FoxO1-negative cells are cancer stem-like cells in pancreatic ductal adenocarcinoma. Sci Rep 2015; 5:10081.

Abstract
Flow cytometry assays using aldehyde dehydrogenase (ALDH) activity or CD133 positivity to isolate cancer stem cells (CSCs) are widely applied but have limitations. Thus, characterization of CSC makers for a specific cancer is potentially important. We have previously shown that miR-21 regulates cancer cell growth via FoxO1 in pancreatic ductal adenocarcinoma (PDAC). Here, we areported evidence of FoxO1-negative PDAC cells as CSCs in PDAC. Both ALDH-high and CD133-high cell fractions isolated from PDAC of the patients expressed high levels of miR-21 and null FoxO1. Cultured PDAC cells were virally transduced with GFP under FoxO1 promoter. GFP (FoxO1)-null PDAC cells expressed high levels of miR-21, and grew more quickly than FoxO1-positive PDAC cells. Moreover, the fold increases in growth of FoxO1-negative vs FoxO1-positive cells were greater than CD133-high vs CD133-low cells, or ALDH-high vs ALDH-low cells. Further, FoxO1-negative cells formed tumor spheres in culture and developed tumors after serial adoptive transplantation into NOD/SCID mice, while the FoxO1-positive cells did not. Finally, selective elimination of FoxO1-negative cells completely inhibited the growth of PDAC cells. Together, these data suggest that FoxO1-negative cells as CSCs in PDAC, and targeting FoxO1-negative cells in PDAC may provide better therapeutic outcome.

Abstract
The molecular regulation of the growth of colorectal cancer (CRC) cells is not completely understood. Here, we report expression of Lgr5, a stem cell marker for the intestine and hair follicle, in some of the CRC cells in the patients. To determine the role of Lgr5-positive cells in the tumorigenesis of CRCs, we prepared an adeno-associated virus (AAV) that carries diphtheria toxin fragment A (DTA) under the control of Lgr5 promoter (AAV-pLgr5-DTA). Transduction of several CRC cell lines with this virus selectively killed Lgr5-positive cells, resulting in significant inhibition of the CRC cell growth in vitro and in vivo. Thus, our data highlight a potential role of Lgr5-positive cells in the tumorigenesis of CRCs, and suggest that treating these Lgr5-positive cells in CRCs may substantially improve the outcome of CRC therapy.

Abstract
OBJECTIVES Reduced increase in serum placental growth factor (PLGF) levels frequently occurs in patients with pre-eclampsia (PE) and thus has been used as a predictive factor for developing PE. However, it has remained elusive how shortage of PLGF could affect pancreatic endocrine homoeostasis and function in pregnancy to lead to development of gestational diabetes mellitus (GDM). MATERIALS AND METHODS We used l-NAME injection in mice, as a model of human PE, in which PLGF levels were significantly reduced. RESULTS We not only confirmed reduced serum PLGF levels in patients with PE but also detected strong correlation of serum PLGF levels and presence of GDM. We found that growth of beta cell mass during pregnancy was significantly impaired by l-NAME injection, as a result of reduced beta cell proliferation. This may explain the higher risk of developing GDM in patients with PE. Moreover, provision of exogenous PLGF in l-NAME-treated pregnant mice significantly rescued beta cell proliferation, with subsequent increase in beta cell mass, suggesting that shortage in PLGF may be responsible for impaired beta cell growth and higher occurrence of GDM in patients with PE. CONCLUSIONS Our study highlighted a pivotal role for PLGF in prevention and treatment of GDM in patients with PE.
