knockdown of usf1 inhibits the vasculogenic mimicry of glioma cells via stimulating snhg16 mir 212 3p and linc00667 mir 429 axis
Molecular therapy. Nucleic acids, 2019Co-Authors: Di Wang, Jian Zheng, Xiaobai Liu, Yixue Xue, Libo Liu, Heng Cai, Yunhui LiuAbstract:The anti-angiogenic treatment of malignant glioma cells is an effective method to treat high-grade gliomas. However, due to the presence of vasculogenic mimicry (VM), the anti-angiogenic treatment of gliomas is not significantly effective in improving overall patient median survival. Therefore, this study investigated the mechanism of mimic formation of angiogenesis in gliomas. The results of this experiment indicate that the expression of upstream transcription factor 1 (USF1) is upregulated in glioma tissues and cells. USF1 knockdown inhibits the proliferation, migration, invasion, VM, and expression of VM-associated proteins in glioma cells by stimulating SNHG16 and linc00667. These two long non-coding RNAs (lncRNAs) regulate ALHD1A1 through the competing endogenous RNA (ceRNA) mechanism influencing the VM of glioma. This study is the first to demonstrate that the USF1/SNHG16/miR-212-3p/ALDH1A1 (aldehyde dehydrogenase-1) and USF1/linc00667/miR-429/ALDH1A1 axis regulates the VM of glioma cells, and these findings might provide a novel strategy for glioma treatment.

ALDH1A1 mRNA expression in association with prognosis of triple-negative breast cancer.
Oncotarget, 2015Co-Authors: Yan Liu, Qiuyin Cai, Ying Zheng, Michelle L. Baglia, Sarah Nechuta, Pingping Bao, William J. Blot, Wei Zheng, Hui Cai, Xiao-ou ShuAbstract:ALDH1 is a crucial element in the retinoic acid signaling pathway regulating the self-renewal and differentiation of normal stem cells, and may play an important role in cancer progression. However, research on ALDH1 gene expression and breast cancer prognosis has yielded conflicting results. We evaluated the association between tumor tissue ALDH1A1/ALDH1A3 mRNA expression and triple-negative breast cancer (TNBC) prognosis in the Shanghai Breast Cancer Survival Study (SBCSS, N=463), Nashville Breast Health Study (NBHS, N=86), and Southern Community Cohort Study (SCCS, N=47). Gene expression was measured in RNA isolated from breast cancer tissues. In the SBCSS, higher ALDH1A1 mRNA level was associated with improved disease-free (HR=0.87, 95% CI: 0.80-0.95, per log unit change) and overall survival (HR=0.85, 95% CI: 0.78-0.93 per log unit change) independent of age at diagnosis, TNM stage and treatment. We replicated the findings for overall survival in the NBHS and SCCS (HR = 0.27, 95% CI: 0.10-0.73) and for disease-free survival by a meta-analysis of four publicly-available gene expression datasets (HR = 0.86, 95% CI: 0.76-0.97). No significant association was found for ALDH1A3.Our study suggests high expression of ALDH1A1 mRNA in tumor tissues may be an independent predictor of a favorable TNBC outcome.

Abstract 2773: Association of ALDH1A1 gene expression with survival of triple-negative breast cancer
Epidemiology, 2015Co-Authors: Yan Liu, Qiuyin Cai, Ying Zheng, Michelle L. Baglia, Sarah Nechuta, Pingping Bao, William J. Blot, Wei Zheng, Xiao-ou ShuAbstract:Aldehyde dehydrogenases (ALDH) are a family of enzymes that catalyze aldehyde into carboxylic acids via the NAD(P)+-dependent oxidation. Several ALDH family members have been identified in humans, including ALDH1A1, ALDH1A3, ALDH2, ALDH3A1, and ALDH4A1. ALDH1A1 is a crucial element in the retinoic acid signaling pathway regulating the self-renewal and differentiation of normal stem cells. It ALDH1A1 has been suggested as one of breast cancer stem cell markers and may play an important role in breast cancer prognosis. However, previous research on ALDH1A1 and breast cancer prognosis has yielded conflicting results. We analyzed the association between mRNA expression of ALDH1A1 in tumor tissues and survival of triple-negative breast cancer (TNBC: ER-/PR-/HER2-) using data and samples from three cohorts of breast cancer patients, including 469 cases from the Shanghai Breast Cancer Survival Study (SBCSS), 86 cases from the Nashville Breast Health Study (NBHS), and 47 cases from the Southern Community Cohort Study (SCCS). Gene expression levels were measured in total RNA isolated from microdissected archival formalin-fixed paraffin-embedded breast cancer tissues using Nanostring nCounter assays. The associations between ALDH1A1 mRNA expression levels and recurrence/breast cancer mortality and overall mortality were evaluated by multivariate survival analysis using the Cox regression model. Data from the SCCS and NBHS were combined in the analysis because both studies were conducted among US women and had a small sample size. The levels of ALDH1A1 mRNA expression were consistently and positively associated with disease free and overall survival independent of age at diagnosis and TNM stage in both Chinese and US women with TNBC. Compared to those with ALDH1A1 mRNA expression below the median, TNBC patients with ALDH1A1 mRNA expression above the median had a reduced risk of recurrence/breast cancer mortality (HR = 0.60, 95% CI: 0.39-0.92) and overall mortality (HR = 0.70, 95% CI: 0.47-1.05) in the SBCSS and reduced overall mortality in the SCCS/NBHS (HR = 0.27,95% CI: 0.10-0.74). Additional analyses of the SBCSS cohort stratified by basal-like breast cancer subtype showed that ALDH1A1 mRNA expression was similarly associated with reduced risk of recurrence/breast cancer mortality and total mortality in both basal-like and non-basal like TNBC patients, although the point estimates were not significant due to the smaller sample size. In addition, we found that patients with a higher tumor grade had a lower level of ALDH1A1 mRNA expression but did not observe an association with TNM stage. Our study suggests that the mRNA expression of ALDH1A1 in tumor tissue may be associated with favorable clinical outcomes in patients with TNBC. Further investigations are needed to understand the biological mechanism(s) underlying the observed association. Citation Format: Yan Liu, Qiuyin Cai, Ying Zheng, Michelle L.
