In all experiments, (AKR x DBA2) FI mice, approximately 20 grams in weight, bearing leukemia L 1210, were used as test objects. Pieces from a 7-day tumor were implanted subcutaneously by trocar in the axillary region. Groups of ten mice each were injected intraperitoneally with the test compound, starting 24 or 72 hours after implantation, as specified in the table. The dose used in these studi...

Natural resistance-associated macrophage protein (NRAMP) encoded by the Slc11a1 gene is a membrane-associated transporter of divalent metal ions. Murine Slc11a1 has two known alleles, a functional Slc11a1Gly169, which is found in DBA2/J, NOD/LtJ, and 129p3/J and related mouse strains, and a non-functional Slc11a1Asp169, that is found in C56Bl/6J (B6) and BALB/cJ mice. B6 mice congenic for Slc11...

Thalidomide's reported ability to inhibit angiogenesis has led to clinical trials determining its effectiveness in combating various types of cancer. This study explored thalidomide's antitumorigenic potential when administered alone and in combination with cisplatin to DBA2/J mice whose tumors were induced by murine erythroleukemic cells. Thalidomide treatment alone produced no significant inh...

BACKGROUND C57BLKS/J (BLKS) mice are susceptible to islet exhaustion in insulin-resistant states as compared with C57BL6/J (B6) mice, as observed by the presence of the leptin receptor (Lepr) allele, Leprdb/db. Furthermore, DBA2/J (DBA) mice are also susceptible to beta-cell failure and share 25% of their genome with BLKS; thus the DBA genome may contribute to beta-cell dysfunction in BLKS mice...

Understanding the genetic influence on ECG time intervals and heart rate (HR) is important for identifying the genes underlying susceptibility to cardiac arrhythmias. The objective of this study was to determine the genetic influence on ECG parameters and their age-related changes in mice. ECGs were recorded in lead I on 8 males and 8 females from each of 28 inbred strains at the ages of 6, 12,...

Alcohol-dependence is a chronic disease with a dramatic and expensive social impact. Previous studies have indicated that the blockade of two monoaminergic receptors, α1b-adrenergic and 5-HT2A, could inhibit the development of behavioral sensitization to drugs of abuse, a hallmark of drug-seeking and drug-taking behaviors in rodents. Here, in order to develop a potential therapeutic treatment o...
