View SamplesMacrophages in tumor microenvironment have been characterized as M1- and M2-polarized subtypes. This study sought to investigate the effects of different macrophage subtypes on the biological behavior and global gene expression profiles of lung cancer cells. Expression microarray and bioinformatics analyses indicated that the different macrophage subtypes mainly regulated genes involved in cell cycle, cytoskeletal remodeling, coagulation, cell adhesion and apoptosis pathways in A549 cells, a pattern that correlated with the altered behavior of A549 cells observed after coculture with macrophage subtypes.

View SamplesThe mammary gland at early stages of pregnancy undergoes fast cell proliferation, yet the mechanism to ensure its genome integrity is largely unknown. Here we show that pregnancy enhances expression of genes involved in numerous pathways, including most genes encoding replisomes. In mouse mammary glands, replisome genes are positively regulated by estrogen/ERa signaling but negatively regulated by BRCA1. Upon DNA damage, BRCA1 deficiency markedly enhances DNA replication initiation. BRCA1 deficiency also preferably impairs DNA replication checkpoints mediated by ATR and CHK1 but not by WEE1, which inhibits DNA replication initiation through CDC7-MCM2 pathway and enables BRCA1-deficient cells to avoid further genomic instability. Thus, BRCA1 and WEE1 inhibit DNA replication initiation in a parallel manner to ensure genome stability for mammary gland development during pregnancy.
BRCA1 represses DNA replication initiation through antagonizing estrogen signaling and maintains genome stability in parallel with WEE1-MCM2 signaling during pregnancy.

View SamplesWe report the high-throughput profiling of brain RNA from three Drosophila stains: dBRWD3PX2/+, dBRWD3PX2/PX2 and dBRWD3PX2/PX2, yemGS21861/GS21861. By obtaining over 50 million reads of sequence, WE compared the transcriptomic differences among the brains from these three stains. We found that the expression of 871 genes was significantly different between heterozygous control and homozygous dBRWD3 mutant brains (484 upregulated genes, 387 downregulated genes, p<0.05). Gene ontology (GO) analysis of the 871 genes revealed a broad spectrum of biological processes, ranging from synaptic activity to housekeeping metabolism subjective to dBRWD3 regulation. Among the 387 downregulated genes, the expression of 360 genes (92.8%) was increased in the dBRWD3, yem double mutant brains compared with dBRWD3 mutant. Among the 484 upregulated genes, the expression of 412 genes (85.1%) was decreased in the double mutant brains. These differential genes were evenly distributed on X chromosome and autosomes (149 on X, 178 on 2L, 154 on 2R, 166 on 3L, and 207 on 3R). These analyses indicate that dBRWD3 regulates gene expression in the brain mainly through the HIRA/YEM complex. Overall design: Examination of brain transcriptome in 3 Drosophila strains.

View SamplesEpstein-Barr virus (EBV) Rta is a latent-lytic molecular switch evolutionarily conserved in all gamma-herpesviruses. In previous studies, doxycycline-inducible Rta was shown to potently produce an irreversible G1 arrest followed by cellular senescence in 293 cells. Here, we demonstrate that in this system the inducible Rta not only reactivates resident genome of EBV but also that of Kaposis sarcoma-associated herpesvirus (KSHV), to similar efficiency. However, Rta-induced senescence program was terminated by the robust viral lytic cycle replication that eventually caused cell death. Furthermore, prior to the abrupt expression of immediate-early protein (EBV BZLF1 or KSHV RTA), Rta simultaneously down-regulates cell cycle activators (c-Myc, CDK6, CCND2) and up-regulates senescence-related genes (p21, 14-3-3s). Since Rta is a viral immediate-early transcriptional activator, it is envisioned that during the initial stage of viral reactivation, Rta may engage to modulate the host transcriptome, to halt cell cycle progression, and to maintain an ideal environment for manufacturing infectious virions.
