Studies on anti-LP-1 and anti-Tamm-Horsfall glycoprotein in chronic liver disease using ADCC assay against antigen-coated target cells. (2007)

Shimomura, Hiroyuki

To study autoantibodies against liver cell surface membrane clinically, anti-LP-1 and anti-Tamm-Horsfall glycoprotein (THGP) were determined in the sera of patients with various liver diseases. They...

Quantitation of Hepatitis C Virus RNA in Liver Tissue as a Predictive Marker of the Response to Interferon Therpay in Chronic Hepatitis C (2007)

Hasui, Toshimi, Shimomura, Hiroyuki, Tsuji, Hideyuki, Wato, Masaki, Tsuji, Takao

Recently, factors predicting the response to interferon (IFN) therapy against hepatitis C virus (HCV) have received much attention. To evaluate the usefulness of the quantitation of intrahepatic HCV...

Virological and serological characterization of asymptomatic blood donors positive for anti-hepatitis C virus antibody. (2007)

Tsuji, Hideyuki, Shimomura, Hiroyuki, Wato, Masaki, Kondo, Junichi, Tsuji, Takao

To study the virological and serological characteristics of asymptomatic hepatitis C virus (HCV) carriers, 165 blood donors positive for antibody against HCV proteins by the second generation assay,...

Relationship between Response to Interferon Therapy and Detection of Hepatitis C Virus RNA by Differential Flotation Centrifugation (2007)

Wato, Masaki, Shimomura, Hiroyuki, Fujio, Kozo, Tsuji, Hideyuki, Kondo, Junichi, Fujioka, Shin-ichi, ...

We purified an apurinic/apyrimidinic (AP) endonuclease from mouse ascites sarcoma (SR-C3H/He) cells. The enzyme showed nicking activity on acid-depurinated DNA but not on untreated, intact DNA. It...

Detection of negative strand RNA of hepatitis C virus in infected liver and serum. (2007)

Nakagawa, Hiroshi, Shimomura, Hiroyuki, Hasui, Toshimi, Tsuji, Hideyuki, Tsuji, Takao

The negative strand RNA of hepatitis C virus, supposed to be a replicative intermediate of the virus appears to indicate viral replication. In this study, we detected the negative strand RNA by using...

Hepatitis C virus antibody titration in patients with chronic hepatitis C, before and after interferon treatment. (2007)

Takahashi, Michiko, Yamada, Gotaro, Miyamoto, Rieko, Doi, Toshihiko, Endo, Hisashi, Nishimoto, Hiroshi, ...

We measured hepatitis C virus antibody titers in 13 patients with chronic hepatitis C to determine whether titration of hepatitis C virus antibody was useful or not, to predict and evaluate the...

Anti-C100-3 antibody status, viral genomic sequences, and clinical features in chronic hepatitic patients with hepatitis C virus RNA in sera. (2007)

Morii, Kazuhiko, Shimomura, Hiroyuki, Nakagawa, Hiroshi, Hasui, Toshimi, Tsuji, Takao

Since detection of hepatitis C virus RNA by the polymerase chain reaction (PCR) showed that there existed anti-C100-3 (anti-HCV) antibody negative patients infected with HCV, we attempted to find out...

Genetic variation of putative core gene in hepatitis C virus. (2007)

Fujio, Kozo, Shimomura, Hiroyuki, Tsuji, Takao

Genetic variation of hepatitis C virus was assessed. We prepared RNA fractions from 21 patients' sera which were positive for hepatitis C virus RNA, synthesized their cDNAs, and amplified fragments,...

Relationship of serum markers of hepatitis B and C virus replication in coinfected patients. (2007)

Tsuji, Hideyuki, Shimomura, Hiroyuki, Fujio, Kozo, Wato, Masaki, Kondo, Junichi, Hasui, Toshimi, ...

To evaluate viral interference between hepatitis B and C, we studied coinfected patients serologically and molecular biologically. Twenty-seven patients positive for hepatitis B surface antigen...

Mutations in the hepatitis B virus preS2 region and abrogated receptor activity for polymerized human albumin. (2006)

Kondo, Junichi, Shimomura, Hiroyuki, Fujioka, Shin-ichi, Iwasaki, Yoshiaki, Takagi, Shinjiro, Ohnishi, Yasuhiro, ...

The preS2 region of the hepatitis B virus (HBV) has been reported to have human polymerized albumin receptor (PAR) activity, which correlates with viral replication. Here, we studied the genomic...

Identification of a target antigen recognized by a mouse monoclonal antibody to the bile canalicular surface of rat hepatocytes with a random phage display library. (2006)

Ariyoshi, Masanori, MIzuno, Motowo, Morisue, Yoshiko, Shimada, Morizou, Fujita, Shirou, Nasu, Junichirou, ...

We developed a monoclonal antibody (MoAb) (clone 5E8) against an antigen on the bile canalicular membrane of rat hepatocyte. By immunoblotting, MoAb 5E8 detected a band of 110 kD. In this study, we...

Improvements in the measurement of stool decay-accelerating factor in the detection of colorectal cancer. (2006)

Ohya, Shogen, Mizuno, Motowo, Kawada, Mikihiro, Nasu, Junichirou, Okada, Hiroyuki, Shimomura, Hiroyuki, ...

We have previously developed an enzyme-linked immunosorbent assay (ELISA) to measure stool decay-accelerating factor (DAF) and found that stool DAF concentrations were significantly elevated in...

Hepatitis C virus quasispecies in cancerous and noncancerous hepatic lesions: the core protein-encoding region. (2006)

Alam, Shahjalal S., Nakamura, Takashi, Naganuma, Atsushi, Nozaki, Akito, Nouso, Kazuhiro, Shimomura, Hiroyuki, ...

We have shown that highly proofreading DNA polymerase is required for the polymerase chain reaction in the genetic analysis of hepatitis C virus (HCV). To clarify the status of HCV quasispecies in...

Development of syngeneic monoclonal anti-idiotype antibodies to mouse monoclonal anti-asialoglycoprotein receptor antibody. (2006)

Hirai, Michio, Mizuno, Motowo, Morisue, Yoshiko, Yoshioka, Masao, Shimada, Morizou, Nasu, Junichirou, ...

Anti-idiotype antibodies (Ab2) play an important role in the homeostasis of immune responses and are related to the development and the disease activity of certain autoimmune diseases. The...
