The Hedgehog (Hh) signaling pathway not only plays important roles in embryogenesis and adult tissue homeostasis, but also in tumorigenesis. Aberrant Hh pathway activation has been reported in a variety of malignant tumors including colon carcinoma. Here, we sought to investigate the regulation of the Hh pathway transcription factor Gli1 by arsenic trioxide and phosphoinositide 3-kinase (PI3K) ...
Recent studies have correlated physical activity with a better prognosis in cachectic patients, although the underlying mechanisms are not yet understood. In order to identify the pathways involved in the physical activity-mediated rescue of skeletal muscle mass and function, we investigated the effects of voluntary exercise on cachexia in colon carcinoma (C26)-bearing mice. Voluntary exercise ...
This study evaluated the in vivo antitumor activity of grape-derived polyphenols. BALB/c mice were subcutaneously implanted with C26 colon carcinoma cells, and 2 d later they received either solvent or red wine polyphenols (RWPs) (100 mg/kg/d, human equivalent dose approximately 500 mg/d) in the drinking water for 25 d. Wistar rats received either solvent or RWPs (100 mg/kg/d, human equivalent ...
A new fluorine-containing anthracycline derivative, ME2303, showed excellent antitumor activity against various experimental tumor models. The i.p. or i.v. administrations of ME2303 on Day 1 or on Days 1, 5, and 9 against i.p.-implanted L1210 leukemia cells rendered more than 50% of mice tumor free at wide ranges of nontoxic doses, whereas the incidence of cure obtained with Adriamycin (ADM) wa...
BACKGROUND Xanthones are a group of oxygen-containing heterocyclic compounds with remarkable pharmacological effects such as anti-cancer, antioxidant, anti-inflammatory, and antimicrobial activities. METHODS A xanthones extract (81% α-mangostin and 16% γ-mangostin), was prepared by crystallization of a toluene extract of G. mangostana fruit rinds and was analyzed by LC-MS. Anti-colon cancer e...
Invasion into the matrix is one of hallmarks of malignant diseases and is the first step for tumor metastasis. Thus, analysis of the molecular mechanisms of invasion is essential to overcome tumor cell invasion. In the present study, we screened for colon carcinoma-specific genes using a cDNA microarray database of colon carcinoma tissues and normal colon tissues, and we found that fermitin fam...
BACKGROUND Metastasis to penis usually arises from genitourinary organs, but in rare cases, metastasis comes from the sigmoid colon. Furthermore, very few cases of penile metastasis of primary sigmoid colon carcinoma have been reported. CASE PRESENTATION We described a case of a 53-year-old man with penile metastasis of sigmoid colon carcinoma along with a review of the literature. Physical e...
ADAM28, a member of the ADAM (a disintegrin and metalloproteinase) gene family, is over-expressed by carcinoma cells and the expression correlates with carcinoma cell proliferation and progression in human non-small cell lung and breast carcinomas. To study the molecular mechanisms of ADAM28 gene expression in carcinoma cells, we examined the expression of ADAM28 in MadinDurby canine kidney (MD...
Particulate carriers such as polymeric micelles (PMs) and liposomes have been investigated to increase drug accumulation in tumors and reduce distribution to healthy tissues. In this study, we prepared PM and hybrid nanoparticles (HNPs) with poly(ethylene oxide)-block-poly(methacrylic acid) (PEO-b-PMAA) for loading cisplatin, and evaluated cisplatin release, cytotoxicity, and biodistribution in...
this paper presents four cases of abnormal soft tissue activity in the bone scan of patients with different lesions (lung inflammatory pseudotumor, pulmonary fibrosis, pulmonary metastatic osteosarcoma and metastatic hepatic carcinoma of colon).
