BACKGROUND Several inflammatory disorders of the intestine are characterised by
enhanced expression of tumour necrosis factor α (TNF-α). Monocytes and macrophages …

Serotonin (5-HT) regulates peristaltic and secretory reflexes in the gut. The serotonin
reuptake transporter (SERT; SLC6A4), which inactivates 5-HT, is expressed in the intestinal …

Using Down syndrome as a model for complex trait analysis, we sought to identify loci from
chromosome 21q22. 2 which, when present in an extra dose, contribute to learning …

In the human, mosaicism may occur before implantation; but, to determine when it first
occurs, it is necessary to study the chromosomal complement of all blastomeres. Full …

Tissue recombinants composed of adult human prostatic epithelium (hPrE) and rat
urogenital sinus mesenchyme (rUGM) were grafted beneath the renal capsule of athymic …

We report the molecular cloning and characterization of 4.1 N, a novel neuronal homolog of
the erythrocyte membrane cytoskeletal protein 4.1 (4.1 R). The 879 amino acid protein …

Through an unusual differentiation process, human trophoblast progenitors
(cytotrophoblasts) give rise to tumor-like cells that invade the uterus. By an unknown …

Physical mapping of small genomic DNA fragments or expressed sequences by in situ
hybridization is typically limited by the size of the target DNA sequence. Isolation of large …

In Escherichia coli DNA replication is carried out by the coordinated action of the proteins
within a replisome. After replication initiation, the two bidirectionally oriented replisomes …
