CURRENT PUBLICATIONS (Ranked by Impact Factor of the Journal)
CD95 Promotes Tumor Growth The results demonstrate that CD95 has a growth-promoting role during tumorigenesis and indicate that efforts to inhibit its activity rather than to enhance it should be considered during cancer therapy. [Nature]
Hematopoietic Origin of Pathological Grooming in Hoxb8 Mutant Mice It has been suggested that the grooming dysfunction results from a nociceptive defect, also exhibited by Hoxb8 mutant mice. However, bone marrow transplant experiments and cell type-specific disruption of Hoxb8 reveal that these two phenotypes are separable, with the grooming phenotype derived from the hematopoietic lineage and the sensory defect derived from the spinal cord cells. [Cell]
A Genome-Wide RNA Interference Screen Reveals an Essential CREB3L2-ATF5-MCL1 Survival Pathway in Malignant Glioma with Therapeutic Implications The results reveal an essential survival pathway in malignant glioma, whereby activation of a RAS–mitogen-activated protein kinase or phosphoinositide-3-kinase signaling cascade leads to induction of the transcription factor cAMP response element–binding protein-3–like-2 (CREB3L2), which directly activates ATF5 expression. ATF5, in turn, promotes survival by stimulating transcription of myeloid cell leukemia sequence-1 (MCL1), an antiapoptotic B cell leukemia-2 family member. [Nat Med]
An Autoimmune-Mediated Strategy for Prophylactic Breast Cancer Vaccination Researchers found that immunoreactivity against alpha-lactalbumin provides substantial protection and therapy against growth of autochthonous tumors in transgenic mouse models of breast cancer and against 4T1 transplantable breast tumors in BALB/c mice. [Nat Med]
An Integrated Network of Androgen Receptor, Polycomb, and TMPRSS2-ERG Gene Fusions in Prostate Cancer Progression The findings provide a working model in which TMPRSS2-ERG plays a critical role in cancer progression by disrupting lineage-specific differentiation of the prostate and potentiating the EZH2-mediated dedifferentiation program.
