Mutant IAA21 genes from Dendrocalamus sinicus Chia et J. L. Sun inhibit stem and root growth in transgenic tobacco by interacting with ARF5.

Woody bamboos are important resource of industrial fibres. Auxin signaling plays a key role in multiple plant developmental processes, as yet the role of auxin/indole acetic acid (Aux/IAA) in culm development of woody bamboos has not been previously characterized. Dendrocalamus sinicus Chia et J.

Cross-neutralizing Anti-hemagglutinin Antibodies Isolated from Patients Infected with Avian Influenza A (H5N1) Virus.

Objective: To recover broad-neutralizing monoclonal antibodies (BnAbs) from avian influenza A (H5N1) virus infection cases and investigate their genetic and functional features.

Methods: We screened the Abs repertoires of expanded B cells circulating in the peripheral blood of H5N1 patients. The genetic basis, biological functions, and epitopes of the obtained BnAbs were assessed and modeled.

[A study of CXCR4/SDF-1 in hepatocellular carcinoma and liver cirrhosis].

Objective: To investigate the expressions of stromal cell-derived factor-1 (SDF-1) and CX chemokine receptor-4 (CXCR-4) in patients with hepatocellular carcinoma (HC) and liver cirrhosis.

Methods: Peripheral blood and/or ascites fluid were collected from 39 hepatocellular carcinoma patients, 16 patients with liver cirrhosis, 12 with hepatitis and 12 healthy donors. The SDF-1 expression was assayed by ELISA and CXCR-4 was measured by immunohistochemical methods.
