This IL-6-related decrease in gp130 was accompanied by a reduction in mRNA expression of TNFα, Socs3 and Bax. After 4 weeks of microbead-induced ocular hypertension, both microbead- and saline-injected (control) eyes of IL-6−/− mice exhibited higher expression of TNFα, compared to WT mice. The gene discussed is TNF; the disease is ocular hypertension.
