Affymetrix Human Gene 1.0 ST Array (hugene10st)
Description
In order to evaluate the identification of genes and pathways, the global gene expression profiles were assessed in response to GO and rGO on Human hepatoma (HepG2) cells. We performed whole genome DNA microarray experiments using HepG2 cells exposed to GO and rGO for 24h.

Description
In the immune system various parameters and immune functions are controlled by the circadian system. To investigate molecular mechanisms that link the circadian clock and the immune system we analyzed the transcriptom of peritoneal macrophages from mice collected in a time course for two consecutive days. We found that more than 8% of expressed genes are under circadian control including many important regulators in pathogen recognition, signal transduction and cytokine secretion.

Description
Previously, we identified Ras homologous A (RHOA) as a major signalling hub in gastric cancer (GC), the third-most common cause of cancer death in the world, prompting us to rationally design an efficacious inhibitor of this oncogenic GTPase. Here, based on that previous work, we extend those computational analyses, and in silico modeling approaches, to further pharmacologically optimize anti-RHOA hydrazide derivatives for greater anti-GC potency. Two of these, JK-136 and JK-139, potently inhibited cell viability and migration/invasion of GC cell lines, and mouse xenografts, diversely expressing RHOA. Moreover, JK-136’s binding affinity for RHOA was >140-fold greater than Rhosin, a nonclinical RHOA inhibitor. Network analysis of JK-136/139-associated transcriptomes showed different functional contexts, compared to those following treatment with Rhosin. We strongly assert that identifying and targeting oncogenic signalling hubs, such as RHOA, represents an emerging strategy for the design, characterization, and translation of new antineoplastics, against gastric and other cancers.

Description
Metastasis of human tumours to LNs is a universally negative prognostic factor. LN stromal cells (SCs) play a crucial role in enabling T cell responses, and since tumour metastases modulate their structure and function, this interaction may suppress immune responses to tumour antigens. However the SC subpopulations that respond to infiltration of malignant cells into human LNs have not been defined. Using microarray, we sought to assess gene expression profiles of two distinct SC subpopulations isolated from melanoma-infiltrated LNs.
