In medium containing low concentrations of serum, rat 13762NF mammary adenocarcinoma cell lines and clones (MTPa and MTC; isolated from the locally growing tumor) of low metastatic potential to lung did not exhibit a growth response to lung-conditioned medium, whereas a highly metastatic cell clone

β¦ Synopsis
We have previously shown that culture medium conditioned by lung fragments contains mitogenic activity for lung-metastasizing tumor cells but not for their non-metastatic counterparts. The growth-promoting component from media conditioned by rat and porcine lungs has been purified and partially characterized as a M, = 66,000 (unreduced) or M, = 72,000 (reduced) glycoprotein [

## Abstract Stromal cellβderived Factorβ1Ξ± (SDFβ1Ξ±) stimulates the migration of bone marrow (BM) cells, similar to vascular endothelial growth factor (VEGF). We previously demonstrated that inhibition of VEGF~165~ by small interfering RNA inhibited Ewing's sarcoma tumor growth, tumor vessel formati
## Abstract ## BACKGROUND. Somatic mutations of the epidermal growth factor receptor (__EGFR__) gene in nonsmallβcell lung cancer (NSCLC) may predict responsiveness to tyrosine kinase inhibitors. These mutations are commonly identified using DNA sequencing methods. Although considered the gold sta
## BACKGROUND. Antagonists of bombesin/gastrin-releasing peptide (BN/GRP) have been developed to block the autocrine stimulatory effect of BN/GRP on tumors such as small cell lung carcinoma (SCLC). Although several studies have addressed the intracellular events that follow the formation of the re
## Abstract ## BACKGROUND. Epidermal growth factor receptor tyrosine kinase inhibitors (EGFRβTKIs) have demonstrated clinical benefit in patients with nonsmall cell lung cancer (NSCLC), particularly those with tumors that have EGFRβTK domain mutations. Moreover, the EGFR and cyclooxygenase (COX)β2
