Noninvasive Identification of Viable Cell Populations in Docetaxel-Treated Breast Tumors Using Ferritin-Based Magnetic Resonance Imaging

Background Cancer stem cells (CSCs) are highly tumorigenic and are responsible for tumor progression and chemoresistance. Noninvasive imaging methods for the visualization of CSC populations within tumors in vivo will have a considerable impact on the development of new CSC-targeting therapeutics. Methodology/Principal Findings In this study, human breast cancer stem cells (BCSCs...

A practical scoring system to determine whether to proceed with surgical resection in recurrent glioblastoma

Background To determine the benefit of surgical management in recurrent glioblastoma, we analyzed a series of patients with recurrent glioblastoma who had undergone surgery, and we devised a new scale to predict their survival.

Usefulness of MS-MLPA for detection of MGMT promoter methylation in the evaluation of pseudoprogression in glioblastoma patients

Pseudoprogression is a major diagnostic dilemma in current treatment protocols for malignant gliomas that involve concurrent chemoradiotherapy. We hypothesized that methylation-specific multiplex ligation probe amplification (MS-MLPA), an assay that permits semiquantitative evaluation of promoter methylation, may be used to diagnose pseudoprogression based on the quantification...

CELL BIOLOGY AND SIGNALING

Ikaros, a DNA-binding protein also known as Ikaros family zinc finger protein 1 (IKZF1), was initially shown to function critically in hematopoietic differentiation. Deletion or mutation of Ikaros has been associated with lymphoblastic, as well as acute and chronic myelogenous leukemias demonstrating that Ikaros can act as a tumor suppressor. Ikaros is predominantly expressed in...

CLIN-NEURO/MEDICAL ONCOLOGY

PURPOSE: This study was performed to evaluate the incidence of seizures with its implications on disease progression and the diagnostic value of post-ictal magnetic resonance images (MRI) during the management of high-grade gliomas (HGGs). PATIENTS AND METHODS: A total of 406 consecutive patients with newly diagnosed HGGs were retrospectively reviewed. The incidence of seizure...
