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...

We analyzed the effect of antithymocyte globulin (ATG) with or without androgens in 121 patients with aplastic anemia. Fifty-three patients with moderate to severe aplastic anemia were prospectively randomized to receive ATG with or without oral androgens. Eleven of 26 patients (42%) receiving ATG plus androgen responded, including three complete and eight partial responses. Twelve of 27 patien...

Macroautophagy (hereafter autophagy) functions in the nonselective clearance of cytoplasm. This process participates in many aspects of cell physiology, and is conserved in all eukaryotes. Autophagy begins with the organization of the phagophore assembly site (PAS), where most of the AuTophaGy-related (Atg) proteins are at least transiently localized. Autophagy occurs at a basal level and can b...

The uptake and tissue distribution of [3H]methotrexate [( 3H]MTX) at doses of 5 mg/kg i.p. either free or linked to anti-EL4 immunoglobulin G (AELG) or normal rabbit globulin (NRG) was studied in EL4 lymphoma-bearing C57BL/6J mice. When the uptakes of MTX-AELG, MTX-NRG, and free MTX were assayed as cell-associated 3H activity, comparison 3 hr after administration showed that uptake of MTX admin...

Insufficient expression of factor VIII (fVIII) is a major hurdle in the development of successful nucleic acid treatments for hemophilia. However, we recently showed that under myeloablative and reduced-intensity total body irradiation (TBI) conditioning, transplantation of hematopoietic stem cells (HSCs) transduced with recombinant retroviruses containing B domain-deleted porcine fVIII (BDDpfV...
