Description
The combination of defined factors with small molecules targeting epigenetic factors is a strategy that has been shown to enhance optimal derivation of human iPSCs and could be used for therapeutic and regenerative medicine applications. In this study, we showed that a new first-in-class dual G9a/DNMT inhibitor CM272 compound improves the standard four-factor reprogramming efficiency of human fibroblast. The use of CM272 facilitates the generation of iPSC with only two factors, OCT4 and SOX2, allowing the removal of potentially oncogenic factors such as cMYC or KLF4. Taking a closer look at the early events occurring during cell reprogramming we demonstrated that treatment with our G9a/DNMT dual inhibitor induces heterochromatin relaxation, facilitates the engagement of OCT4 and SOX2 transcription factors to the genome and promotes mesenchymal to epithelial transition during cell reprogramming. Thus, the use of this new G9a/DNMT dual inhibitor compound may represent an interesting alternative for improving cell reprogramming.

Description
Amyotrophic Lateral Sclerosis (ALS) is generally a late onset neurodegenerative disease. Mutations in the Cu/Zn superoxide dismutase 1 (SOD1) gene accounts for approximately 20% of familial ALS and 2% of all ALS cases. Although a number of hypothesis have been proposed to explain mutant SOD1 toxicity, the molecular mechanisms of the disease remain unclear. SOD1 linked ALS is thought to function in a non-cell autonomous manner such that the motoneurons are critical for the onset and glia contribute to the progress of the disease. To dissect the roles of motoneurons and glia, we used the Gal4-UAS system to determine gene expression changes following the expression of mutant human SOD1 (G85R) selectively in either motoneurons or glia, and concurrently in motoneurons and glia of flies. We conducted a microarray on young (5 days old) and old (45 days old) flies expressing G85R in these cell types and identified a number of genes involved in a variety of processes. The candidate genes identified by this screen may help elucidate the individual and combined contributions of motoneurons and glial cells in ALS.

Description
Sperm cells represent the male partner that fuses with the egg cell during fertilization in all multi-cellular eukaryotic organisms, and, in flowering plants, is a founder of both embryo and nutritive endosperm. We examined the transcriptome of Oryza sativa ssp. japonica using the Affymetrix 57K rice genome GeneChip to provide an overview of genes activated in the paternal gamete.

Description
Glioblastoma multiforme is the most lethal form of glioma with an overall survival at 5 years nearly null, which mainly results from acquired resistance to therapies. Large scale sequencing studies on human cancer biopsies defined IRE1alpha as the fifth most oncogenic mutated kinase in human cancer. IRE1alpha is a major component of the Unfolded Protein Response signaling and increasing evidence suggests that it is a central player in GBM development.

Dual IRE1 RNase functions dictate glioblastoma development.

Mastic oil from Pistacia lentiscus variation chia, a blend of bioactive terpenes with recognized medicinal properties, has been recently shown to exert anti-tumor activity. Lewis lung carcinoma (LLC) cells are mastic oil-susceptible cells and were used in this work to study the effects of mastic oil at the transcriptomic level.

Description
Colorectal cancer is a highly heterogeneous disease, with variable molecular pathogenesis, involving multiple genomic and epigenetic alterations. Despite the significant advances in the diagnosis and treatment of colorectal cancer, it remains a major cause of morbidity and mortality, especially for countries in Northern America and Europe, as also in New Zealand & Australia. In this direction, the introduction of gene expression signatures derived from multiple layers of molecular & clinical dissection, may resolve the problems of heterogeneity and improve robust disease stratification
