UTX-mediated enhancer and chromatin remodeling suppresses myeloid leukemogenesis through noncatalytic inverse regulation of ETS and GATA programs.
(NATURE PUBLISHING GROUP, 2018-06-01)
The histone H3 Lys27-specific demethylase UTX (or KDM6A) is targeted by loss-of-function mutations in multiple cancers. Here, we demonstrate that UTX suppresses myeloid leukemogenesis through noncatalytic functions, a ...
Suppression of interferon gene expression overcomes resistance to MEK inhibition in KRAS-mutant colorectal cancer.
(NATURE PUBLISHING GROUP, 2019-03-07)
Despite showing clinical activity in BRAF-mutant melanoma, the MEK inhibitor (MEKi) trametinib has failed to show clinical benefit in KRAS-mutant colorectal cancer. To identify mechanisms of resistance to MEKi, we employed ...
Antibody-Neutralized Reovirus Is Effective in Oncolytic Virotherapy.
(AMER ASSOC CANCER RESEARCH, 2018-10-01)
Immunotherapy is showing promise for otherwise incurable cancers. Oncolytic viruses (OVs), developed as direct cytotoxic agents, mediate their antitumor effects via activation of the immune system. However, OVs also stimulate ...
HSF1 Is Essential for Myeloma Cell Survival and A Promising Therapeutic Target.
(AMER ASSOC CANCER RESEARCH, 2018-05-15)
Purpose: Myeloma is a plasma cell malignancy characterized by the overproduction of immunoglobulin, and is therefore susceptible to therapies targeting protein homeostasis. We hypothesized that heat shock factor 1 (HSF1) ...
Structural rearrangements of the RNA polymerase III machinery during tRNA transcription initiation.
(ELSEVIER SCIENCE BV, 2018-04-01)
RNA polymerase III catalyses the synthesis of tRNAs in eukaryotic organisms. Through combined biochemical and structural characterisation, multiple auxiliary factors have been identified alongside RNA Polymerase III as ...
CRISPR screens identify genomic ribonucleotides as a source of PARP-trapping lesions.
(NATURE PUBLISHING GROUP, 2018-07-12)
The observation that BRCA1- and BRCA2-deficient cells are sensitive to inhibitors of poly(ADP-ribose) polymerase (PARP) has spurred the development of cancer therapies that use these inhibitors to target deficiencies in ...
IL-23 secreted by myeloid cells drives castration-resistant prostate cancer.
(NATURE PORTFOLIO, 2018-07-19)
Patients with prostate cancer frequently show resistance to androgen-deprivation therapy, a condition known as castration-resistant prostate cancer (CRPC). Acquiring a better understanding of the mechanisms that control ...
Detection of circulating tumour cell clusters in human glioblastoma.
(NATURE PUBLISHING GROUP, 2018-08-14)
Human glioblastoma (GBM) is a highly aggressive, invasive and hypervascularised malignant brain cancer. Individual circulating tumour cells (CTCs) are sporadically found in GBM patients, yet it is unclear whether multicellular ...
Investigating Low-Velocity Fluid Flow in Tumors with Convection-MRI.
(AMER ASSOC CANCER RESEARCH, 2018-04-01)
Several distinct fluid flow phenomena occur in solid tumors, including intravascular blood flow and interstitial convection. Interstitial fluid pressure is often raised in solid tumors, which can limit drug delivery. To ...
Genome-wide and high-density CRISPR-Cas9 screens identify point mutations in PARP1 causing PARP inhibitor resistance.
(NATURE PUBLISHING GROUP, 2018-05-01)
Although PARP inhibitors (PARPi) target homologous recombination defective tumours, drug resistance frequently emerges, often via poorly understood mechanisms. Here, using genome-wide and high-density CRISPR-Cas9 ...
