We describe a point mutation creating an additional ATG codon in the 5' untranslated region (UTR) of the HAMP gene, in a patient with juvenile hemochromatosis. By transient in vitro transfection studies, we provide evidence that the additional ATG is functional and prevents normal hepcidin production by inducing an aberrant translation initiation of the pre-hepcidin mRNA.

It was possible to gauge the inhibition of mouse beta-glucuronidase expression by injecting RNA, made from both strands of subclones of a cosmid containing the complete gene, into mouse blastomeres at the four-cell stage. Although our initial screen did not identify the 5' region, we were able to isolate a subclone containing homology to 20 bp coding for N-terminal amino acids of rat and human ...

Autophagy is a highly regulated process about which relatively little is known, particularly concerning the transcriptional control of autophagy regulation. A new study identifies a key regulator of the expression of autophagy-related genes, thereby providing insights into the signalling pathways modulating autophagy.

Forty-six patients with venous immunosickness” variety. The heterophile antibody logically mediated or lymphoproliferative was composed of a mixture of gamma G diseases received goat antihuman thymoand gamma M antibodies and was partially cyte antisera globulin (ATG) therapy. absorbed by ATG. Serum sickness did not Heterophile antibody production occurred occur in any of these patients, in spit...

HvHKT1 mediates K(+) or Na(+) uniport in yeast cells if the expression promoter is joined directly to the HvHKT1 cDNA, and Na(+)-K(+) symport if a 59 nucleotide polylinker is inserted. Our results show that three ATG triplets in the polylinker decreased the synthesis of the transporter and that the lower amount of transporter caused the functional change. With the rice HKT1 cDNA, the 59 nt poly...
