Copper-64 based radiopharmaceuticals for brain tumors and hypoxia imaging

Numai utilizatorii înregistrați pot traduce articole

Introduction: The most common and aggressive primary malignancy of the central nervous system is Glioblastoma that, as a wide range of malignant solid tumor, is characterized by extensive hypoxic regions. A great number of PET

Overexpression of s6 kinase 1 in brain tumours is associated with induction of hypoxia-responsive genes and predicts patients' survival.

mTOR/S6K pathway is a crucial regulator of cell growth and metabolism. Deregulated signalling via S6K has been linked to various human pathologies, including metabolic disorders and cancer. Many of the molecules signalling upstream of S6K have been shown to be either mutated or overexpressed in

Immunoexpression patterns for Hypoxia-inducible Factor-1α and von Hippel-Lindau protein, in relation to Hsp90, of human brain tumors.

Numai utilizatorii înregistrați pot traduce articole

The pathogenesis of many tumors, including brain tumors, has been associated with hypoxia, which induces the transcriptional activity of hypoxia-inducible Factor-1α (HIF-1α). HIF-1α is normally degradated by the von Hippel-Lindau protein (pVHL) but, in hypoxia, pVHL/HIF-1α interaction is inhibited

Collective behavior of brain tumor cells: the role of hypoxia.

Numai utilizatorii înregistrați pot traduce articole

We consider emergent collective behavior of a multicellular biological system. Specifically, we investigate the role of hypoxia (lack of oxygen) in migration of brain tumor cells. We performed two series of cell migration experiments. In the first set of experiments, cell migration away from a tumor

Hypoxia and neural stem cells: from invertebrates to brain cancer stem cells.

Numai utilizatorii înregistrați pot traduce articole

Oxygen is a fundamental element for all living organisms, and modifications in its concentration influence several physiological and pathological events such as embryogenesis, development and also aging. Regulation of oxygen levels is an important factor in neural stem cell biology (e.g.

The expression of hypoxia-inducible factor-1 in primary brain tumors.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Primary brain tumors are common type of neoplasms. The most common are astrocytic tumors, so do meningiomas of various grades. The etiology is still unknown; however, there are lots of data presenting new theories about genetic alterations responsible for low- or high-grade astrocytic

Imaging and analytical methods as applied to the evaluation of vasculature and hypoxia in human brain tumors.

Numai utilizatorii înregistrați pot traduce articole

Tissue hypoxia results from the interaction of cellular respiration, vascular oxygen carrying capacity, and vessel distribution. We studied the relationship between tumor vasculature and regions of low pO(2) using quantitative analysis of binding of the 2-nitroimidazole EF5 given to patients

Killing of brain tumor cells by hypoxia-responsive element mediated expression of BAX.

Numai utilizatorii înregistrați pot traduce articole

The presence of radioresistant hypoxic cells in human brain tumors limits the overall effectiveness of conventional fractionated radiation therapy. Tumor-specific therapies that target hypoxic cells are clearly needed. We have investigated the expression of suicide genes under hypoxia by a

Importance of hypoxia in the biology and treatment of brain tumors.

Numai utilizatorii înregistrați pot traduce articole

The resistance of gliomas to treatment with radiation and antineoplastic drugs may result in part from the effects of the extensive, severe hypoxia that is present in these tumors. It is clear that brain tumors contain extensive regions in which the tumor cells are subjected to unphysiological

Assessment of the Prognostic Value of Radiomic Features in 18F-FMISO PET Imaging of Hypoxia in Postsurgery Brain Cancer Patients: Secondary Analysis of Imaging Data from a Single-Center Study and the Multicenter ACRIN 6684 Trial.

Numai utilizatorii înregistrați pot traduce articole

Hypoxia is associated with resistance to radiotherapy and chemotherapy in malignant gliomas, and it can be imaged by positron emission tomography with ¹⁸F-fluoromisonidazole (¹⁸F-FMISO). Previous results for patients with brain cancer imaged with ¹⁸F-FMISO at a

Expression of hypoxia-inducible carbonic anhydrases in brain tumors.

Numai utilizatorii înregistrați pot traduce articole

Malignant brain tumors exhibit distinct metabolic characteristics. Despite high levels of lactate, the intracellular pH of brain tumors is more alkaline than normal brain. Additionally, with increasing malignancy, brain tumors display intratumoral hypoxia. Carbonic anhydrase (CA) IX and XII are

Hypoxia-cultured human adipose-derived mesenchymal stem cells are non-oncogenic and have enhanced viability, motility, and tropism to brain cancer.

Numai utilizatorii înregistrați pot traduce articole

Adult human adipose-derived mesenchymal stem cells (hAMSCs) are multipotent cells, which are abundant, easily collected, and bypass the ethical concerns that plague embryonic stem cells. Their utility and accessibility have led to the rapid development of clinical investigations to explore their

Prediction of Hypoxia in Brain Tumors Using a Multivariate Model Built from MR Imaging and 18F-Fluorodeoxyglucose Accumulation Data.

Numai utilizatorii înregistrați pot traduce articole

PURPOSE

The aim of this study was to generate a multivariate model using various MRI markers of blood flow and vascular permeability and accumulation of ¹⁸F-fluorodeoxyglucose (FDG) to predict the extent of hypoxia in an ¹⁸F-fluoromisonidazole

Tumor hypoxia and microscopic diffusion capacity in brain tumors: a comparison of (62)Cu-Diacetyl-Bis (N4-Methylthiosemicarbazone) PET/CT and diffusion-weighted MR imaging.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE The aim of this study was to clarify the relationship between tumor hypoxia and microscopic diffusion capacity in primary brain tumors using (62)Cu-Diacetyl-Bis (N4-Methylthiosemicarbazone) ((62)Cu-ATSM) PET/CT and diffusion-weighted MR imaging (DWI). METHODS This study was approved by the

Inhibition of ADAM17 reduces hypoxia-induced brain tumor cell invasiveness.

Numai utilizatorii înregistrați pot traduce articole

The membrane-anchored metalloproteinase tumor necrosis factor-alpha-converting enzyme (TACE/a disintegrin and metalloproteinase [ADAM] 17) is key in proteolytic ectodomain shedding of several membrane-bound growth factors, cytokines and receptors. The expression and activity of ADAM17 increases
