BACKGROUND The aim of this study was to perform a comprehensive evaluation of the renin-angiotensin system (RAS) in prostate cancer. METHODS We investigated the expression of RAS components in prostate cancer cells treated with hormonal agents. Real-time PCR data showed the expression of the AT1

OBJECTIVE Doxorubicin (DOX) chemotherapy can cause cardiac complications. Angiotensin converting enzyme inhibitors (ACEI) may protect against these complications. We performed a pharmacokinetics (PK) study to determine whether DOX levels are altered in the presence of ACEI. METHODS In this

The highest incidence of nasopharyngeal carcinoma (NPC) is in southeast China, including Taiwan. Many side effects have been observed following radiation therapy with chemotherapy; hence, exploring new treatment modalities for NPC is an important future direction. Angiotensin-(1-7) [Ang-(1-7)] is an

BACKGROUND Renin-angiotensin system inhibitors (RAS inhibitors) are antihypertensive agents with potential antitumor effects. However, various studies have yielded conflicting results on the influence of RAS inhibitors on survival of cancer patients. The aim of this study was to evaluate the effect

To elucidate the microvascular mechanisms of change in tumor blood flow elicited by vasopressors, a functional morphometric study of the s.c. microcirculation within a rat transparent chamber was performed. Arteriolar vessels were classified centripetally (a2-a5) according to Strahler's method.

Elevation of the mean arterial blood pressure to approximately 150 mmHg by infusion of angiotensin II resulted in an approximate 5.7-fold selective increase in blood flow in tumor tissue without increasing blood flow in normal tissue. This finding of no autoregulation of blood flow in tumor tissue

BACKGROUND Angiotensin-(1-7) [Ang-(1-7)] is an endogenous, heptapeptide hormone with anti-proliferative and anti-angiogenic properties. The primary objective of this study was to determine whether Ang-(1-7) effectively reduces prostate cancer metastasis in mice. METHODS Human PC3 prostate cancer

BACKGROUND Cachexia is a metabolic disorder characterised by muscle wasting, diminished response to anti-cancer treatments and poor quality of life. Our objective was to identify blood-based biomarkers of cachexia in advanced cancer patients. Hence, we characterised the plasma cytokine and blood

Angiotensin-induced hypertension chemotherapy (IHC) was investigated in six children with the following advanced malignancies: hepatocellular carcinoma, extraskeletal Ewing's sarcoma, sacrococcygeal malignant teratoma, small round cell tumor of the chest wall, hepatoblastoma and osteogenic sarcoma.

A 10 mHz continuous-wave Doppler system has been used to detect blood flow within a sarcoma implanted in a rabbit's ear. The effects of vasoconstriction produced by intravenous angiotensin II were studied. Criteria are described that enabled differentiation of the Doppler signals from the tumour

OBJECTIVE Renin-angiotensin system (RAS) has been considered not only as a regulator of systemic volume and electrolyte balance but also has been recently involved in various pathological processes such as cancer. In the etiology of breast cancer, dietary factors have been analyzed and especially

Induced hypertension with angiotensin II (AT-II) and the inhibition of kininase with enalapril maleate may increase the tumor targeting of radiolabeled monoclonal antibodies (MAbs). We previously found that short-period infusion of 2.0 microg/kg/min of AT-II enhanced tumor targeting of MAb without

The effects of vasoactive agents propranolol hydrochloride and angiotensin (AT-II) on improving the directed therapy of cancer with the use of conjugate of gastric cancer monoclonal antibody (3H11) and mitomycin C (MMC) were studied. The antibody activity of the conjugate (3H11-HSA-MMC) was retained

BACKGROUND Angiotensin II (AII) type 1 receptor (AT1R) antagonists are used widely as antihypertensive agents, and long-term AT1R blockade may have a protective effect against cancer. We previously demonstrated that specific AT1R blockade with candesartan, an AT1R antagonist, inhibited vascular

The clinical efficacy and indications for Angiotensin II (AT II)-induced hypertension chemotherapy were evaluated as a drug delivery system in 101 patients with advanced carcinoma. The sites of primary tumor studied included stomach (44), pancreas (18), colon (16), esophagus (6), bile duct (4),
