Abstract
Metabolic reprogramming is considered one of the hallmarks of cancer in which cancer cells reprogram some of their metabolic cascades, mostly driven by the specific chemical microenvironment in cancer tissues. The altered metabolic pathways are increasingly being considered as potential targets for cancer therapy. In this view, Aldolase A (ALDOA), a key glycolytic enzyme, has been validated as a candidate oncogene in several cancers. The current study aimed to investigate the role of ALDOA in the initiation and development of colorectal cancer (CRC). In this study, we observed an elevated expression of ALDOA in human CRC tissues and a positive correlation of elevated ALDOA expression with tumor size, invasion depth, LNM, and TNM stage. Kaplan-Meier analysis revealed that elevated ALDOA levels correlated with a poor prognosis in CRC patients with stage I-III, whereas the prognosis tends to be favorable in patients with advanced CRC. In addition, loss of function and gain of function experiments showed that ALDOA promoted CRC cell proliferation and migration in vitro and in vivo. Mechanistically, high ALDOA expression inhibited AMP-activated protein kinase (AMPK) phosphorylation possibly through regulating cellular glycolysis or the formation of v-ATPase-regulator-AXIN/LKB1 complex, which led to Yes-associated protein (YAP) unphosphorylation and enhanced the proliferative and migratory potential of CRC cells. Finally, the positive correlation between ALDOA and YAP signaling was also confirmed in clinical CRC tissues and the public data. Herein, ALDOA was identified to be a new metabolic regulator of YAP that suppresses the activation of AMPK signaling. This could suggest a novel avenue for treating CRC by inhibiting both ALDOA and YAP signaling.
期刊介绍：
Cell Death Discovery is a multidisciplinary, international, online-only, open access journal, dedicated to publishing research at the intersection of medicine with biochemistry, pharmacology, immunology, cell biology and cell death, provided it is scientifically sound. The unrestricted access to research findings in Cell Death Discovery will foster a dynamic and highly productive dialogue between basic scientists and clinicians, as well as researchers in industry with a focus on cancer, neurobiology and inflammation research. As an official journal of the Cell Death Differentiation Association (ADMC), Cell Death Discovery will build upon the success of Cell Death & Differentiation and Cell Death & Disease in publishing important peer-reviewed original research, timely reviews and editorial commentary.
Cell Death Discovery is committed to increasing the reproducibility of research. To this end, in conjunction with its sister journals Cell Death & Differentiation and Cell Death & Disease, Cell Death Discovery provides a unique forum for scientists as well as clinicians and members of the pharmaceutical and biotechnical industry. It is committed to the rapid publication of high quality original papers that relate to these subjects, together with topical, usually solicited, reviews, editorial correspondence and occasional commentaries on controversial and scientifically informative issues.
