Detectable levels (greater than or equal to 0.2 pmol/10(6) cells) of one or more prostanoid species resultant to calcium ionophore A23187-induced biosynthesis from endogenous arachidonic acid were distributed in 28 cell lines derived from different histological classes of lung tumors as follows: large cell undifferentiated carcinoma (3 of 3 cell lines); adenosquamous carcinoma (1 of 2 cell line...
To help identify genes, which may regulate metastasis in lung cancer, we performed representational difference analysis between a patient-derived non-small cell lung carcinoma (NSCLC) and immortalized normal human bronchial epithelial cells. This analysis revealed that bone morphogenetic proteins-2/4 (BMP) mRNA was expressed in the lung carcinoma. BMP-2/4 are known to induce pluripotent cell di...
We investigated the molecular mechanisms of angiogenesis in experimental brain metastasis. Cells from six different human cancer cell lines (proven to produce visceral metastasis) were injected into the internal carotid artery of nude mice. Colon carcinoma (KM12SM) and lung adenocarcinoma (PC14PE6 and PC14Br) cells produced large, fast-growing parenchymal brain metastases, whereas lung squamous...
BACKGROUND Tumor-infiltrating B lymphocytes (TIB) are often observed in lung cancer. The role of TIB in tumor growth has not been well investigated. MATERIALS AND METHODS Forty-four surgically-resected human lung cancer tissues were xenotransplanted into SCID mice. Their blood was collected and the volume of the transplanted tumors was measured regularly. The correlations between the IgG tite...
Cytotoxic activity of gaillardin, a sesquiterpene lactone isolated from Inula oculus-christi L. (Asteraceae), was assessed in the human breast adenocarcinoma cell line MCF-7, human hepatocellular carcinoma cell line HepG-2, human non-small cell lung carcinoma cell line A-549, and human colon adenocarcinoma cell line HT-29, resulting in IC50 values of 6.37, 6.20, 4.76, and 1.81 microg/mL, respec...
Intravenous durvalumab (Imfinzi™; AstraZeneca) is a fully human monoclonal antibody that blocks programmed cell death ligand-1 binding to its receptors (PD-1 and CD80), resulting in enhanced T-cell responses against cancer cells. The US FDA has granted durvalumab accelerated approval for the treatment of patients with locally advanced or metastatic urothelial carcinoma who have disease progress...
Squamous lung cancer is a subtype of non-small cell lung cancer with a poor overall prognosis. We have recently generated a mouse model of squamous lung carcinoma by overexpressing Sex-determining region Y-box 2 (Sox2) and deleting liver kinase B1 (Lkb1) using a lentiviral approach. This model recapitulates the human disease in terms of histopathology, biomarker expression, and signaling pathwa...
The relationship between integrin expression and function in pathologies is often contentious as comparisons between human pathological expression and expression in cell lines is difficult. In addition, the expression of even integrins αvβ6 and αvβ8 in tumor cell lines is not comprehensively documented. Here, we describe rabbit monoclonal antibodies (RabMabs) against the extracellular domains o...
