Morphological Ultrasound Microimaging of Thyroid in Living Mice
The objective of the study was to explore high-frequency ultrasound (HFUS) for noninvasive microimaging of thyroid in living mice. Thyroid examination was performed by HFUS in 10 normal C57BL/6 mice, eight mice treated by propylthiouracil, and 22 …

Pioglitazone induces a proadipogenic antitumor response in mice with PAX8-PPARgamma fusion protein thyroid carcinoma.
Approximately 35% of follicular thyroid carcinomas harbor a chromosomal translocation that results in expression of a paired box gene 8-peroxisome proliferator-activated receptor γ gene (PPARγ) fusion protein (PPFP). To better understand the oncogenic …

Mutationally Activated BRAFV600E Elicits Papillary Thyroid Cancer in the Adult Mouse
Mutated BRAF is detected in approximately 45% of papillary thyroid carcinomas (PTC). To model PTC, we bred mice with adult-onset, thyrocyte-specific expression of BRAF(V600E). One month following BRAF(V600E) expression, mice displayed increased thyroid …

Functional micro-ultrasound imaging of rodent cerebral hemodynamics.
Healthy cerebral microcirculation is crucial to neuronal functioning. We present a new method to investigate microvascular hemodynamics in living rodent brain through a focal cranial window based on high-frequency ultrasound imaging. The method has a …

Delta-like ligand 4-notch blockade and tumor radiation response.
BACKGROUND: The microenvironment plays an important role in regulating tumor response to radiotherapy. Ionizing radiation can disrupt tumor vasculature, and Notch pathway inhibition can interfere with functional angiogenesis. We explored the potential …

The selective hypoxia inducible factor-1 inhibitor PX-478 provides in vivo radiosensitization through tumor stromal effects.
Hypoxia inducible factor-1 (HIF-1) promotes tumor cell adaptation to microenvironmental stress. HIF-1 is up-regulated in irradiated tumors and serves as a promising target for radiosensitization. We initially confirmed that the orally bioavailable HIF-1 …

Size and spatial orientation of uterine tissue transplants on the peritoneum crucially determine the growth and cyst formation of endometriosis-like lesions in mice.
BACKGROUND: In many studies in rodents, intraperitoneal endometriosis-like lesions are surgically induced by syngeneic or autologous transplantation of uterine tissue samples, which are sutured to the abdominal wall. However, until now the surgical …

Non- invasive in vivo analysis of a murine aortic graft using high resolution ultrasound microimaging.
INTRODUCTION: As yet, murine aortic grafts have merely been monitored histopathologically. The aim of our study was to examine how these grafts can be monitored in vivo and non-invasively by using high-resolution ultrasound microimaging to evaluate …

Monitoring transplanted islets by high-frequency ultrasound
Islet transplantation is a cell replacement therapy to improve glycometabolic control in type 1 diabetic patients. Establishing methods to monitor engrafted islets, as well as the islet preparation, is important when performing islet transplantation. …

Novel small interfering RNA-containing solution protecting donor organs in heart transplantation.
BACKGROUND: Ischemia/reperfusion injury is a major factor in graft quality and subsequent function in the transplantation setting. We hypothesize that the process of RNA interference may be used to "engineer" a graft to suppress expression of genes …
