Disappearance of gadolinium enhancement in a chemoresistant astrocytoma of the tectum after high-dose interferon beta.
نویسندگان
چکیده
Interferon beta 6 million units per week was administered to a patient with an aggressive astrocytoma in the tectum that was resistant to cisplatin, etoposide, vinblastine, and the oral alkylating agent temozolomide. The tumor was immunopositive for O6-methylguanine-DNA methyltransferase (MGMT). Interferon beta caused the disappearance of the gadolinium-enhanced lesion in the tectum. Interferons have apoptotic and antiangiogenic effects on tumor cells, and the lesion's disappearance may have been induced by complexes of these effects. Administration of interferon beta might have a favorable effect on tectal gliomas that are immunopositive for MGMT and resistant to chemoradiotherapy including temozolomide.

Introduction: Escherichia coli (E.coli) is one of the most widely used hosts for the production of recombinant proteins. The main problem in getting high product yields and productivity is the accumulation of acetic acid (acetate) as an unwanted metabolic by-product. In this study, an antisense-based strategy as a metabolic engineering approach was employed to hamper the acetate excretion probl...
