Abstract
Pancreatic cancer, a highly fibrotic and hypovascular tumor, is thought to have unique metabolic characteristics in surviving and proliferating in malnutritional microenvironments. In this study, we compared the differences in the ability of pancreatic cancer cells to adapt to glucose-free conditions with liver cancer cells, which are representative of hypervascular tumors. Three pancreatic cancer cells and two liver cancer cells were used to examine the transcriptional expression levels of molecules involved in intracellular amino acid uptake, epithelial-mesenchymal transition (EMT), and cancer stemness under glucose deprivation. The results showed that the proliferative activity of pancreatic cancer cells under glucose deprivation was significantly lower than that of liver cancer cells, but the expression levels of amino acid transporters were significantly higher. Among them, L-type amino acid transporter 1 (LAT1) upregulation was unique in concert with increased expression of the EMT regulator SNAIL and the cancer stemness marker doublecortin-like kinase 1. LAT1 knockdown canceled the upregulation of SNAIL in glucose-starved pancreatic cancer cells, suggesting a mechanistic link between the two molecules. When LAT1 was stimulated by its substrate leucine, the SNAIL expression was upregulated dose-dependently. Collectively, pancreatic cancer cells reprogrammed metabolism to adapt to energy crises involving leucine-induced SNAIL upregulation.

[PMID: 38803001 PMCID: PMC11135080 DOI: 10.1177/15330338241257490] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/18/2024] [Revised: 04/07/2024] [Accepted: 04/09/2024] [Indexed: 05/29/2024] Open
Abstract
Objectives: This study aimed to investigate the effect of specific small ubiquitin-like modifier (SUMO) proteases 1 (SENP1)-mediated deSUMOylation on the malignant behavior of glioma stem cells (GSCs) under hypoxia conditions and evaluate the clinical value of prevention in glioma patients. Introductions: Under hypoxic conditions, upregulated hypoxia-inducible factor 1α (HIF1α) expression in GSCs activates Wnt/β-catenin signaling pathways, which provide rich nutritional support for glioblastoma (GBM). SENP1-mediated deSUMOylation stabilizes the expression of HIF1α and β-catenin, leading to the occurrence of GSCs-initiated tumorigenesis. Targeting SENP1-mediated deSUMOylation may suppress the malignancy of GSCs and disrupt GBM progression. Methods: The expression of SENP1 in different World Health Organization grades was observed by immunohistochemistry and western blot. Lentivirus-packaged SENP1shRNA downregulated the expression of SENP1 in GSCs, and the downregulated results were verified by western blotting and polymerase chain reaction. The effects of LV-SENP1shRNA on the migration and proliferation of GSCs were detected by scratch and cloning experiments. The effect of LV-SENP1shRNA on the tumor formation ability of GSCs was observed in nude mice. Immunoprecipitation clarified the mechanism of SENP1 regulating the malignant behavior of GSCs under hypoxia. The correlation between the expression level of SENP1 and the survival of glioma patients was determined by statistical analysis. Results: SENP1 expression in GSCs derived from clinical samples was upregulated in GBM. SUMOylation was observed in GSCs in vitro, and deSUMOylation, accompanied by an increase in SENP1 expression, was induced by hypoxia. SENP1 expression was downregulated in GSCs with lentivirus-mediated stable transfection, which attenuated the proliferation and differentiation of GSCs, thus diminishing tumorigenesis. Mechanistically, HIF1α induced activation of Wnt/β-catenin, which depended on SENP1-mediated deSUMOylation, promoting GSC-driven GBM growth under the hypoxia microenvironment. Conclusion: Our findings indicate that SENP1-mediated deSUMOylation as a feature of GSCs is essential for GBM maintenance, suggesting that targeting SENP1 against GSCs may effectively improve GBM therapeutic efficacy.

Abstract
Glioblastoma multiforme (GBM) is probably the only tumor in which a unique epigenetic alteration, namely methylation of the MGMT gene, possesses direct clinical relevance. Now with the emergence of aberrant N6 methyladenosine (m6A) modifications (the most common epigenetic modification of mRNA, closely linked to the autophagy process) in cancer, the epi-transcriptomic landscape of GBM pathobiology has been expanded. Considering this, herein, we systematically analyzed m6A regulators, assessed their correlation with autophagy-related genes (ATG), and established a long non-coding RNAs (lncRNA)-dependent prognostic signature (m6A-autophagy-lncRNAs) for GBM. Our analysis identified a novel signature of five long non-coding RNAs (lncRNAs: ITGA6-AS1, AC124248.1, NFYC-AS1, AC025171.1, and AC005229.3) associated with survival of GBM patients, and four among them clearly showed cancer-associated potential. We further validated and confirmed the altered expression of two lncRNAs (AC124248.1, AC005229.3) in GBM associated clinical samples using RT-PCR. Concerning the prognostic ability, the obtained signature determined high-/low-risk groups in GBM patients and showed sensitivity to anticancer drugs. Collectively, the m6A-autophagy-lncRNAs signature presented in the study is clinically relevant and is the first attempt to systematically predict the potential interaction between the three key determinants (m6A, autophagy, lncRNA) in cancer, particularly in GBM.

J Cell Mol Med 2023; 27:2533-2546. [PMID: 37488774 PMCID: PMC10468654 DOI: 10.1111/jcmm.17852] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 07/05/2023] [Accepted: 07/08/2023] [Indexed: 07/26/2023] Open
Abstract
The pancreatic stellate cells (PSCs) play an important role in the development of pancreatic cancer (PC) through mechanisms that remain unclear. Exosomes secreted from PSCs act as mediators for communication in PC. This study aimed to explore the role of PSC-derived exosomal small RNAs derived from tRNAs (tDRs) in PC cells. Exosomes from PSCs were extracted and used to detect their effects on PC cell proliferation, migration and invasion. Exosomal tDRs profiling was performed to identify PSC-derived exosomal tDRs. ISH and qRT-PCR were used to examine the tRF-19-PNR8YPJZ levels and clinical value in clinical samples. The biological function of exosomal tRF-19-PNR8YPJZ was determined using the CCK-8, clone formation, wound healing and transwell assays, subcutaneous tumour formation and lung metastatic models. The relationship between the selected exosomal tRF-19-PNR8YPJZ and AXIN2 was determined by RNA sequencing, luciferase reporter assay. PSC-derived exosomes promoted the proliferation, migration, and invasion of PC cells. Novel and abundant tDRs are found to be differentially expressed in PANC-1 cells after treatment with PSC-derived exosomes, such as tRF-19-PNR8YPJZ. PC tissue samples showed markedly higher levels of tRF-19-PNR8YPJZ than normal controls. Patients with PC exhibiting high tRF-19-PNR8YPJZ expression had a highly lymph node invasion, metastasis, perineural invasion, advanced clinical stage and poor overall survival. Exosomal tRF-19-PNR8YPJZ from PSCs targeted AXIN2 in PC cells and decreased its expression, thus activating the Wnt pathway and promoting proliferation and metastasis. Exosomal tRF-19-PNR8YPJZ from PSCs promoted proliferation and metastasis in PC cells via AXIN2.

Anti-VEGF therapy selects for clones resistant to glucose starvation in ovarian cancer xenografts. J Exp Clin Cancer Res 2023; 42:196.

Abstract
BACKGROUND Genetic and metabolic heterogeneity are well-known features of cancer and tumors can be viewed as an evolving mix of subclonal populations, subjected to selection driven by microenvironmental pressures or drug treatment. In previous studies, anti-VEGF therapy was found to elicit rewiring of tumor metabolism, causing marked alterations in glucose, lactate ad ATP levels in tumors. The aim of this study was to evaluate whether differences in the sensitivity to glucose starvation existed at the clonal level in ovarian cancer cells and to investigate the effects induced by anti-VEGF therapy on this phenotype by multi-omics analysis. METHODS Clonal populations, obtained from both ovarian cancer cell lines (IGROV-1 and SKOV3) and tumor xenografts upon glucose deprivation, were defined as glucose deprivation resistant (GDR) or glucose deprivation sensitive (GDS) clones based on their in vitro behaviour. GDR and GDS clones were characterized using a multi-omics approach, including genetic, transcriptomic and metabolic analysis, and tested for their tumorigenic potential and reaction to anti-angiogenic therapy. RESULTS Two clonal populations, GDR and GDS, with strikingly different viability following in vitro glucose starvation, were identified in ovarian cancer cell lines. GDR clones survived and overcame glucose starvation-induced stress by enhancing mitochondrial oxidative phosphorylation (OXPHOS) and both pyruvate and lipids uptake, whereas GDS clones were less able to adapt and died. Treatment of ovarian cancer xenografts with the anti-VEGF drug bevacizumab positively selected for GDR clones that disclosed increased tumorigenic properties in NOD/SCID mice. Remarkably, GDR clones were more sensitive than GDS clones to the mitochondrial respiratory chain complex I inhibitor metformin, thus suggesting a potential therapeutic strategy to target the OXPHOS-metabolic dependency of this subpopulation. CONCLUSION A glucose-deprivation resistant population of ovarian cancer cells showing druggable OXPHOS-dependent metabolic traits is enriched in experimental tumors treated by anti-VEGF therapy.

Erythrose inhibits the progression to invasiveness and reverts drug resistance of cancer stem cells of glioblastoma. Med Oncol 2023; 40:104.

Abstract
Glioblastoma (GBM) is the most frequent brain cancer and more lethal than other cancers. Characteristics of this cancer are its high drug resistance, high recurrence rate and invasiveness. Invasiveness in GBM is related to overexpression of matrix metalloproteinases (MMPs) which are mediated by wnt/β-catenin and induced by the activation of signaling pathways extracellularly activated by the cytokine neuroleukin (NLK) in cancer stem cells (CSC). Therefore, in this work we evaluated the effect of the tetrose saccharide, erythrose (Ery), a NLK inhibitor of invasiveness and drug sensitization in glioblastoma stem cells (GSC). GSC were obtained from parental U373 cell line by a CSC phenotype enrichment protocol based on microenvironmental stress conditions such as hypoxia, hipoglycemia, drug exposition and serum starvation. Enriched fraction of GSC overexpressed the typical markers of brain CSC: low CD133+ and high CD44; in addition, epithelial to mesenchyme transition (EMT) markers and MMPs were increased several times in GSC vs. U373 correlating with higher invasiveness, elongated and tubular mitochondrion and temozolomide (TMZ) resistance. IC50 of Ery was found at nM concentration and at 24 h induced a severe diminution of EMT markers, MMPs and invasiveness in GSC. Furthermore, the phosphorylation pattern of NLK after Ery exposition also was affected. In addition, when Ery was administered to GSC at subIC50, it was capable of reverting TMZ resistance at concentrations innocuous to non-tumor cancer cells. Moreover, Ery added daily induced the death of all GSC. Those findings indicated that the phytodrug Ery could be used as adjuvant therapy in GBM.
