Changes in Utilization and Discard of Hepatitis C-Infected Donor Livers in the Recent Era.

The impact of interferon (IFN)-free direct-acting antiviral (DAA) hepatitis C virus (HCV) treatments on utilization and outcomes associated with HCV-positive deceased donor liver transplantation (DDLT) is largely unknown. Using the Scientific Registry of Transplant Recipients, we identified 25 566 HCV-positive DDLT recipients from 2005 to 2015 and compared practices according to the introduction of DAA therapies using modified Poisson regression. The proportion of HCV-positive recipients who received HCV-positive livers increased from 6.

Magnetic Resonance Imaging in Diagnosis and Monitoring of Hepatocellular Carcinoma in Liver Transplantation: A Comprehensive Review.

Hepatocellular carcinoma (HCC) is the most common primary liver cancer. One of the most important risk factors of HCC is cirrhosis. The optimal treatment of HCC is liver transplantation, since it treats both the underlying cirrhosis and the cancer.

Large-scale sequence analysis of avian influenza isolates.

The spread of H5N1 avian influenza viruses (AIVs) from China to Europe has raised global concern about their potential to infect humans and cause a pandemic. In spite of their substantial threat to human health, remarkably little AIV whole-genome information is available. We report here a preliminary analysis of the first large-scale sequencing of AIVs, including 2196 AIV genes and 169 complete genomes.

Characterization of the MLL partner gene AF15q14 involved in t(11;15)(q23;q14).

Translocations interrupting the mixed lineage leukemia gene (MLL) occur in 7-10% of acute lymphoblastic leukemia (ALL) and 5-6% of acute myeloid leukemia (AML) cases. One of these translocations, t(11;15)(q23;q14), occurs rarely in both ALL and AML. The gene on chromosome 15, AF15q14, was cloned recently in a patient with AML-M4.

Inactivating mutations and overexpression of BCL10, a caspase recruitment domain-containing gene, in MALT lymphoma with t(1;14)(p22;q32).

Mucosa-associated lymphoid tissue (MALT) lymphomas most frequently involve the gastrointestinal tract and are the most common subset of extranodal non-Hodgkin lymphoma (NHL). Here we describe overexpression of BCL10, a novel apoptotic signalling gene that encodes an amino-terminal caspase recruitment domain (CARD), in MALT lymphomas due to the recurrent t(1;14)(p22;q32). BCL10 cDNAs from t(1;14)-positive MALT tumours contained a variety of mutations, most resulting in truncations either in or carboxy terminal to the CARD.

Cloning and chromosomal localization of the gene encoding human cyclin D-binding Myb-like protein (hDMP1).

The murine transcription factor murine cyclin D-binding Myb-like protein (mDmp1) arrests the cell cycle in G1 phase, through an activity that can be overridden by direct interaction with the D-type cyclins. Here, we describe the identification, sequence, chromosomal localization, and expression of the human cognate, hDMP1. The hDMP1 cDNA contains a 2280bp open reading frame that shares a high degree of identity with the mDmp1 coding region.

Two candidate downstream target genes for E2A-HLF.

The E2A-HLF fusion gene, formed by the t(17;19)(q22;p13) chromosomal translocation, is thought to drive the leukemic transformation of early B-cell precursors by repressing an evolutionarily conserved apoptotic pathway. To test this hypothesis, we sought to identify downstream targets of E2A-HLF in t(17;19)+ pro-B leukemia cells (UOC-B1) that had been transfected with a zinc-inducible vector encoding a dominant-negative suppressor (E2A-HLF[dn]) of the oncoprotein. Representational difference analysis of mRNAs from E2A-HLF(dn)+ UOC-B1 cells grown with (E2A-HLF inactive) or without (E2A-HLF active) the addition of zinc yielded several differentially expressed cDNA fragments that were individually subcloned.

Sequence of the Sendai virus L gene: open reading frames upstream of the main coding region suggest that the gene may be polycistronic.

The sequence of the L gene of Sendai virus, encompassing 6799 nucleotides, has been determined, completing the primary sequence of the entire virus genome. An open reading frame beginning at position 569 codes for a basic protein of 2048 amino acids with an estimated Mr of 231,608. No nucleotide sequence similarities with the analogous L gene of vesicular stomatitis virus were observed.
