Tyrosine Phosphorylation Inhibits PKM2 to Promote the Warburg Effect and Tumor Growth
Taro Hitosugi,Sumin Kang,Matthew G. Vander Heiden,Tae-Wook Chung,Shannon Elf,Katherine Lythgoe,Shaozhong Dong,Sagar Lonial,Xu Wang,Georgia Z. Chen,Jianxin Xie,Ting-Lei Gu,Roberto D. Polakiewicz,Johannes Roesel,Titus J. Boggon,Fadlo R. Khuri,D. Gary Gilliland,Lewis C. Cantley,Jonathan L. Kaufman,Jing Chen +19 more
TL;DR: The findings suggest that tyrosine phosphorylation regulates PKM2 to provide a metabolic advantage to tumor cells, thereby promoting tumor growth.
Journal ArticleDOI
Phosphoglycerate mutase 1 coordinates glycolysis and biosynthesis to promote tumor growth.
Taro Hitosugi,Lu Zhou,Shannon Elf,Jun Fan,Hee-Bum Kang,Jae Ho Seo,Changliang Shan,Qing Dai,Liang Zhang,Jianxin Xie,Ting-Lei Gu,Peng Jin,Maša Alečković,Gary LeRoy,Yibin Kang,Jessica Sudderth,Ralph J. DeBerardinis,Chi Hao Luan,Georgia Z. Chen,Susan Muller,Dong M. Shin,Taofeek K. Owonikoko,Sagar Lonial,Martha Arellano,Hanna Jean Khoury,Fadlo R. Khuri,Benjamin H. Lee,Keqiang Ye,Titus J. Boggon,Sumin Kang,Chuan He,Jing Chen +31 more
TL;DR: Inhibition of PGAM1 by shRNA or a small molecule inhibitor PGMI-004A results in increased 3-PG and decreased 2-PG levels in cancer cells, leading to significantly decreased glycolysis, PPP flux and biosynthesis, as well as attenuated cell proliferation and tumor growth.
Journal ArticleDOI
Tyrosine Phosphorylation of Mitochondrial Pyruvate Dehydrogenase Kinase 1 Is Important for Cancer Metabolism
Taro Hitosugi,Jun Fan,Tae-Wook Chung,Katherine Lythgoe,Xu Wang,Jianxin Xie,Qingyuan Ge,Ting-Lei Gu,Roberto D. Polakiewicz,Johannes Roesel,Georgia Z. Chen,Titus J. Boggon,Sagar Lonial,Haian Fu,Fadlo R. Khuri,Sumin Kang,Jing Chen +16 more
TL;DR: It is reported that tyrosine phosphorylation enhancesPDHK1 kinase activity by promoting ATP and PDC binding and activates PDHK1 to promote the Warburg effect and tumor growth.
Journal ArticleDOI
Hyperspectral imaging and quantitative analysis for prostate cancer detection.
Hamed Akbari,Luma V. Halig,David M. Schuster,Adeboye O. Osunkoya,Viraj A. Master,Peter T. Nieh,Georgia Z. Chen,Baowei Fei,Baowei Fei +8 more
TL;DR: This imaging method may be able to help physicians to dissect malignant regions with a safe margin and to evaluate the tumor bed after resection and may lead to advances in the optical diagnosis of prostate cancer using HSI technology.
Journal ArticleDOI
Tyrosine Phosphorylation of Lactate Dehydrogenase A Is Important for NADH/NAD+ Redox Homeostasis in Cancer Cells
Jun Fan,Taro Hitosugi,Tae-Wook Chung,Jianxin Xie,Qingyuan Ge,Ting Le Gu,Roberto D. Polakiewicz,Georgia Z. Chen,Titus J. Boggon,Sagar Lonial,Fadlo R. Khuri,Sumin Kang,Jing Chen +12 more
TL;DR: The findings suggest that tyrosine phosphorylation enhances LDH-A enzyme activity to promote the Warburg effect and tumor growth by regulating the NADH/NAD+ redox homeostasis, representing an acute molecular mechanism underlying the enhanced lactate production in cancer cells.
