Cancer Research: Deciphering the role of intestinal crypt cell populations in resistance to chemotherapy (Penalva Lab)

March 30, 2021

Carla Frau, Catherine Jamard, Gaspard Delpouve, Gabriela D. A. Guardia, Christelle Machon, Camilla Pilati, Clementine Le Neve, Pierre Laurent-Puig, Jérôme Guitton, Pedro A. F. Galante, Luiz O. Penalva, Jean-Noel Freund, Christelle de la Fouchardière and Michelina Plateroti Abstract Intestinal crypts are composed of heterogeneous and highly plastic cell populations. Lgr5high-stem cells (SC) are responsible for homeostatic renewal, but other cells can revert to an SC-like phenotype to maintain epithelial integrity. Despite their distinct roles in orchestrating homeostasis, both populations have been designated as […]

Development: The murine intestinal stem cells are highly sensitive to the modulation of the T3/TRα1-dependent pathway (Penalva Lab)

March 30, 2021

Matthias Godart, Carla Frau, Diana Farhat, Maria Virginia Giolito, Catherine Jamard, Clementine Le Nevé, Jean-Noel Freund, Luiz O. Penalva, Maria Sirakov, Michelina Plateroti Abstract The thyroid hormone T3 and its nuclear receptor TRα1 control gut development and homeostasis through the modulation of intestinal crypt cell proliferation. Despite increasing data, in-depth analysis on their specific action on intestinal stem cells is lacking. By using ex vivo 3D […]

Cell Cycle: Regulation of DNA duplication by the mTOR signaling pathway (Houghton)

March 11, 2021

ABSTRACT Accurate and complete DNA replication and separation are essential for genetic information inheritance and organism maintenance. Errors in DNA duplication are the main source of genetic instability. Understanding DNA duplication regulation is the key to elucidate the mechanisms and find treatment strategies for human genetic disorders, especially cancer. The mechanistic target of rapamycin (mTOR) […]

FASEB Journal: Identification of a novel mechanism for meso‐tetra (4‐carboxyphenyl) porphyrin (TCPP) uptake in cancer cells

February 25, 2021

            David J. Elzi,   William E. Bauta,  Jamila R. Sanchez,  Trisha Das, Shweta Mogare, Peter Zannes Fatland,  Moises Iza, Alexander Pertsemlidis,  Vivienne I. Rebel  Abstract Porphyrins are used for cancer diagnostic and therapeutic applications, but the mechanism of how porphyrins accumulate in cancer cells remains elusive. Knowledge of how porphyrins […]

Clinical Cancer Research: The B7-H3-targeting antibody-drug conjugate m276-SL-PBD is potently effective against pediatric cancer preclinical solid tumor models

February 15, 2021

Nathan M. Kendsersky, Jarrett M Lindsay, Edward A. Kolb, Malcolm A. Smith, Beverly A. Teicher, Stephen Erickson, Eric J Earley, Yaël P. Mossé, Daniel Martinez, Jennifer Pogoriler, Kateryna Krytska, Khushbu Patel, David Groff, Matthew Tsang, Samson Ghilu, Yifei Wang, Steven Seaman, Yang Feng, Brad St. Croix, Richard Gorlick, Raushan T. Kurmasheva, Peter J. Houghton and John M. Maris Abstract Purpose: Patients with relapsed pediatric solid malignancies have few therapeutic options, and many of these patients die of their disease. B7-H3 is an immune checkpoint protein encoded by the CD276 gene that is overexpressed in many pediatric cancers. Here, we investigate the […]
