The Wilms tumor suppressor gene WT1 encodes a developmentally regulated transcription factor that is mutated in a subset of embryonal tumors. To test its functional properties, we developed osteosarcoma cell lines expressing WT1 under an inducible tetracycline-regulated promoter. Induction of WT1 resulted in programmed cell death. This effect, which was(More)
The E2F transcription factor has been implicated in the regulation of genes whose products are involved in cell proliferation. Two proteins have recently been identified with E2F-like properties. One of these proteins, E2F-1, has been shown to mediate E2F-dependent trans-activation and to bind the hypophosphorylated form of the retinoblastoma protein (pRB).(More)
The mammalian transcription factor E2F plays an important role in regulating the expression of genes that are required for passage through the cell cycle. This transcriptional activity is inhibited by association with the retinoblastoma tumor suppressor protein (pRB) or its relatives p107 and p103. The first cDNA from the E2F family to be cloned was(More)
The binding of viral oncogenes to cellular proteins is thought to modulate the activities of these cellular targets. The p107 protein is targeted by many viral proteins, including adenovirus E1A, simian virus 40 large T antigen, and human papillomavirus type 16 E7 protein. A panel of monoclonal antibodies against p107 was raised and used to identify(More)
Malnutrition is widespread in Nigeria and has persisted at alarmingly high rate. Nutrition problems are at times due to lack of education and knowledge about healthy nutrition behaviours and practices. The purpose of this study was to examine the knowledge of infant nutrition in Enugu State, Nigeria. Ten focus-Group Discussions (FGDS) were conducted with(More)
The article assessed knowledge of the nutritional and health needs of children among rural dwellers in Nigeria. Focus group discussions were conducted with all male and female groups in four purposively chosen rural communities in Nsukka Senatorial zone of Enugu State. These generated data on participants' knowledge on the nutritional and health needs of(More)
