Crosstalk between Meg3 and miR-1297 regulates growth of testicular germ cell tumor through PTEN/PI3K/AKT pathway.

Maternally Expressed Gene 3 (Meg3) encodes a long non-coding RNA that has been recently shown to regulate tumorigenesis through its interaction with microRNA (miR). We have recently reported that miR-1297 might play a role in the regulation of PTEN/PI3k/Akt signaling pathway in testicular germ cell tumor (TGCT). However, a crosstalk between Meg3 and miR-1297 in TGCT has not been appreciated.

Gene expression profiling of flag leaves at the booting stage in the japonica hybrid rice Huayou14 and its parental lines by microarray.

Gene expression profiling using microarray has contributed significantly to heterosis studies. Using the Affymetrix rice genome array, we investigated gene expression profiles in the flag leaves of the japonica hybrid rice Huayou14 and its parental cultivars Shen9A and Fan14 at the booting stage. A total of 2057 genes differentially expressed (fold change ≥2 or ≤0.

Genetic analysis and fine mapping of LH1 and LH2, a set of complementary genes controlling late heading in rice (Oryza sativa L.).

Heading date in rice (Oryza sativa L.) is a critical agronomic trait with a complex inheritance. To investigate the genetic basis and mechanism of gene interaction in heading date, we conducted genetic analysis on segregation populations derived from crosses among the indica cultivars Bo B, Yuefeng B and Baoxuan 2.

Genetic analysis of heterotic loci detected in a cross between indica and japonica rice (Oryza sativa L.).

The study on the genetic basis of heterosis has received significant attention in recent years. In this study, using a set of introgression lines (ILs) and corresponding testcross F(1) populations, we investigated heterotic loci (HL) associated with six yield-related traits in both Oryza sativa L. subsp.

Genetic-basis analysis of heterotic loci in Dongxiang common wild rice (Oryza rufipogon Griff.).

Heterosis is widely used in genetic crop improvement; however, the genetic basis of heterosis is incompletely understood. The use of whole-genome segregating populations poses a problem for establishing the genetic basis of heterosis, in that interactions often mask the effects of individual loci. However, introgression line (IL) populations permit the partitioning of heterosis into defined genomic regions, eliminating a major part of the genome-wide epistasis.
