Using the rice salt-tolerant mutant 20 as material, a cDNA library was constructed and two salt-inducible clones, SIR5.5 and SIR8.1, were isolated by differential screening. Homology analysis revealed that the two clones together constituted a chimeric rbcL which encoded a truncated large subunit of Rubisco with 337 amino-acids, plus 64 amino-acids of(More)
Drug insensitivity or resistance is a major obstacle for successful treatment of acute myeloid leukemia. MicroRNAs (miRNAs) are small non-coding RNA molecules. Increasing evidence suggests that miRNAs modulate cellular sensitivity to anticancer drugs. We used a specific anti-miR-21 oligonucleotide (AMO-miR-21) to sensitize leukemic HL60 cells to(More)
Arsenic trioxide (ATO), an ancient traditional Chinese medicine, has been successfully used as a therapeutic agent for leukemia. Drug resistance and toxicity are major concerns with the treatment. MicroRNAs (miRNAs) are endogenous small non-coding RNA molecules that might modulate cellular sensitivity to anticancer drugs. miRNA-21 (miR-21) is one of the(More)
MicroRNAs (miRNAs) are endogenous small noncoding RNA molecules involved in modulation of cellular sensitivity to anti-cancer drugs. miRNA-21 (miR-21), one of the most prominent miRNAs in the genesis and progression of many human cancers, has been rarely characterized in myelogenous leukemia. Arsenic trioxide (ATO) was successfully used in the treatment of(More)
MicroRNAs (miRNAs) are small non-coding RNA molecules that are widely involved in cancer-related processes. The microRNA-21 (miR-21) has been identified as the only miRNA overexpressed in a variety of cancers, including leukemia. However, the function of miR-21 is yet unknown in chronic myelogenous leukemia (CML). Antisense oligonucleotides (ASOs), as(More)
Berberine is a natural alkaloid derived from a traditional Chinese herbal medicine. It is known to modulate microRNA (miRNA) levels, although the mechanism for this action is unknown. Here, we previously demonstrate that the expression of 87 miRNAs is differentially affected by berberine in multiple myeloma cells. Among 49 miRNAs that are down-regulated,(More)
