BACKGROUND With a US Food and Drug Administration-labeled indication to treat attention-deficit/hyperactivity disorder (ADHD), the nonstimulant guanfacine has become the preferred α(2)-agonist for ADHD treatment. However, significant interindividual variability has been observed in response to guanfacine. Consequently, hypotheses of a contributing interaction with the ubiquitously expressed dru...

The present study investigated the effects of non-motorized voluntary running on experimental metastasis of B16BL/6 melanoma and spontaneous metastasis of Lewis lung carcinoma (LLC) in male C57BL/6 mice. After 9 weeks of running, mice (n=30 per group) received an intravenous injection of B16BL/6 cells or a subcutaneous injection of LLC cells, and then they were continued with their running acti...

The purpose of this study was to clarify the effects of oxaliplatin on the function and expression of the multidrug efflux transporter P-glycoprotein/MDR1 in a porcine kidney epithelial cell line, LLC-PK1, as a renal tubular epithelial model. LLC-PK1 cells were pretreated with or without oxaliplatin for 48 h, and the growth inhibitory effects of a MDR1 substrate, paclitaxel, and the transport o...

I examined the effects of carp oil, oleic acid, linoleic acid and linolenic acid on tumor growth and metastasis to the liver in mice implanted intrasplenically with highly metastatic Lewis lung carcinoma (LLC) tumors. Carp oil (0.1 or 0.2 mL per mouse) significantly reduced tumor growth and metastasis to the liver. Carp oil at 100 or 1000 mg/L inhibited the DNA synthesis in LLC cells, the capil...

Toxoplasma gondii is an obligate intracellular protozoan parasite that induces antitumor activity against certain types of cancers. However, little information is available regarding the immunologic mechanisms that regulate these effects. For this purpose, C57BL/6 mice were administered either the T. gondii Me49 strain orally or Lewis lung carcinoma (LLC) cells intramuscularly. Survival rates, ...

OBJECTIVES/HYPOTHESIS Human nasal cartilage is hyaline cartilage, although the function and loads placed on it are different depending on the location. We hypothesized that important differences exist between the nasal septal cartilage and lower lateral cartilage (LLC) ultrastructures. Such differences would be important in the field of cartilage engineering. METHODS Ten specimens (6 septum a...

The role of macrophages in tumor metastasis was examined by using migration of a cloned metastatic Lewis lung carcinoma (LLC) variant, LLC-C4, out of glass capillary tubes as an in vitro model for dissemination of tumor cells from a primary tumor mass. Macrophages, derived from LLC tumors of C57BL/6 mice or from peritoneal exudates of mice given injections of complete Freund's adjuvant, enhance...

BACKGROUND Our previous screening study suggested that the cell-adhesions protein Dihydropyrimidinase-like 3 (DPYSL3) was a candidate metastatic lung cancer related molecule. This study aimed to analyze the correlation between DPYSL3 and metastatic lung cancer. METHODS Stable DPYSL3 knockdown Lewis lung carcinoma (LLC) cells were constructed with a retroviral system. Cell migration and invasi...

Cloud providers must dynamically allocate their physical resources to the right client to maximize the benefit that they can get out of given hardware. Cache Allocation Technology (CAT) makes it possible for the provider to allocate last level cache to virtual machines to prevent cache pollution. The provider can also allocate the cache to optimize client benefit. But how should it optimize cli...

BACKGROUND Polymeric fibronectin (polyFN) assembled on suspended breast cancer cells is required for metastasis. Conceivably, drugs that target such polyFN may fight against cancer metastasis. While stilbene analogs trigger pro-apoptotic effect on attached cancer cells, whether they prevent polyFN assembly and metastasis of suspended cancer cells via an apoptosis-independent manner remains unex...
