Jove: Mass Spectrometry Analysis to Identify Ubiquitylation of EYFP-tagged CENP-A (EYFP-CENP-A)

June 10, 2020

Yohei Niikura*1, Lei Fang*2, Risa Kitagawa*3, Peizhao Li1, Yao Xi1, Ju You1, Yan Guo2, Katsumi Kitagawa3 Summary CENP-A ubiquitylation is an important requirement for CENP-A deposition at the centromere, inherited through dimerization between cell division, and indispensable to cell viability. Here we describe mass spectrometry analysis to identify ubiquitylation of EYFP-tagged CENP-A (EYFP-CENP-A) protein. Abstract Studying the structure and the dynamics of […]

Clinical Cancer Research: Evaluation of Eribulin Combined with Irinotecan for Treatment of Pediatric Cancer Xenografts

June 1, 2020

Andrew J. Robles, Raushan T. Kurmasheva, Abhik Bandyopadhyay, Doris A. Phelps, Stephen W. Erickson, Zhao Lai, Dias Kurmashev, Yidong Chen, Malcom A. Smith, and Peter J. Houghton Abstract Purpose: Vincristine combined with camptothecin derivatives showed synergy in preclinical pediatric cancer models, and the combinations are effective in the treatment of childhood solid tumors. We determined whether the synergy between vincristine and irinotecan extends to eribulin, another microtubule inhibitor. Experimental Design: Vincristine or eribulin, alone or […]

Springer Link: Genetic markers for treatment-related pancreatitis in a cohort of Hispanic children with acute lymphoblastic leukemia

May 24, 2020

Allison C. Grimes, Yidong Chen, Hima Bansal, Christine Aguilar, Luz Perez Prado, Gerardo Quezada, Jaime Estrada & Gail E. Tomlinson Abstract Purpose Treatment-related pancreatitis (TRP) is a serious complication occurring in children with acute lymphoblastic leukemia (ALL). Those affected are at high risk for severe organ toxicity and treatment delays that can impact outcomes. TRP is associated with asparaginase, a standard therapeutic agent […]

Using an established breast cancer cellular model, we show that endocrine […]

Cell Chemical Biology: MYC Regulation of D2HGDH and L2HGDH Influences the Epigenome and Epitranscriptome

May 1, 2020

ZhiJun Qiu 1, An-Ping Lin 1, Shoulei Jiang 1, Sara M Elkashef 1, Jamie Myers 1, Subramanya Srikantan 2, Binu Sasi 1, John Z Cao 3, Lucy A Godley 3, Dinesh Rakheja 4, Yingli Lyu 5, Siyuan Zheng 6, Muniswamy Madesh 2, Yuzuru Shiio 7, Patricia L M Dahia 1, Ricardo C T Aguiar 8 Abstract Mitochondrial D2HGDH and L2HGDH catalyze the oxidation of D-2-HG and L-2-HG, respectively, into αKG. This contributes to cellular homeostasis in part by modulating the activity of αKG-dependent dioxygenases. Signals that […]

Familial Cancer: Highly aggressive thoracic desmoid tumors in adolescent siblings with fatal outcomes in an FAP kindred: a need for increased vigilance and intervention in at-risk AYAs

April 13, 2020

Mohamed M. Gad, Anne-Marie Langevin, Aaron J. Sugalski & Gail E. Tomlinson Abstract Desmoid tumors are a manifestation of familial adenomatous polyposis (FAP), associated with mutation of the APC gene. Although considered benign tumors, desmoids can be aggressive and cause considerable morbidity. Known risk factors for desmoid tumor growth include the location of mutations within the APC gene, family […]
