Bovine X hamster and bovine X mouse hybrid somatic cells have been used to investigate the syntenic relationship of nine loci in the bovine that have homologous loci on human chromosome 12. Eight loci, including A2M, GLI, HOX3, IFNG, INT1, KRAS2, NKNB, and PAH, were assigned to the previously identified bovine syntenic group U3 represented by GAPD. However, a single locus from the q-terminus of HSA 12, ALDH2, mapped to a new, previously unidentified autosomal syntenic group. These results indicate the existence of a very large ancestral syntenic group spanning from the p-terminus to q24 of HSA 12 and containing over 4% of the mammalian genome. Additionally, the results predict that ALDH2 is distal to PAH and IFNG on HSA 12, the type II keratin gene complex will reside between q11 and q21 of HSA 12, A2M will map to MMU 6, and LALBA and GLI will map to MMU 15.

Kidney function changes after single-dose administration of borocaptate sodium were studied in rats and in patients with brain tumors. Changes of glomerular filtration rate (GFR) measured as 14C-inulin clearance and urine flow rate (UFR) after a slow intravenous injection of BSH (25 and 50 mg/kg b.w., respectively) were investigated in rats under pentobarbital anesthesia. The effect of BSH has been compared with that of its disulfide (BSSB) which is spontaneously generated by oxidation of BSH during storage. It was found that BSH decreases GFR in relation to dose and, in the same way, causes a temporary increase of UFR. On the other hand, BSSB (50 mg/kg) induced a large reversible decrease of GFR as well as a decrease of urine excretion. Measurements of GFR (inulin clearance), renal plasma flow (PAH clearance) and urine excretion were taken in a group of patients with brain tumors in which boron disposition after an infusion of BSH (25 mg/kg b.w. over 1 h) had been studied. An increase in urine production was the dominant effect (up to 200% of the initial value), with the alterations of GFR and RPF being of minor significance except in one patient with a GFR reduction up to almost 50% the original value. Kidney function changes after BSH or BSSB administration are supposedly related to the high retention of BSH in kidney.

Regional assignment of eight markers to chromosome 2 of Ateles paniscus chamek (APC) confirmed a syntenic association similar to human (HSA) 12q + 14q + 15q. Three HSA 12q markers (RAP1B, PAH and ALDH2) were allocated to a shortest region of overlap (SRO) in APC 2p and found to be syntenic to other HSA 12q markers (PEPB and TCF1). Five HSA 14q markers (CTLA, PAX9, NSP, FOS and CHGA) were allocated to APC 2q and found to be syntenic to other HSA 14q markers (NP, TGM1, and CALM1) and to four HSA 15q markers (THBS1, B2M, HEXA and MPI) but dissociated from markers close to HSA 14qter (CKB) and HSA 15qter (FES-IDH2). Karyotypic comparisons showed an evident homoeology between APC 2p and HSA 12q while APC 2q was similar to an HSA 14qter::HSA 15qter fusion product. Comparative gene mapping data show that the HSA 14q + HSA 15q syntenic association is an ancestral mammalian gene cluster that has been maintained in several primate taxa. Conversely, in Ateles, it has been further associated with HSA 12q while, in Hominoids and Cebus, it has been independently dissociated into two separate syntenic groups, similar to HSA 14q and HSA 15q.
