<strong><em>Abstract</em></strong><strong>—</strong> <em>One hundred and twenty (120) broilers birds of Abore acere breed were used to determine the effect of pawpaw leaf and neem leaf extracts on the haematological profile of broilers birds. The chicks were randomly assigned to four treatments with 30 birds in each treatment. Each treatment was replicated three times with 10 birds per replicate in a completely randomized design (CRD). Treatment 1 received only vaccine and drugs without the leaf extract in their water, treatment 2 and 3 received 150 ml of the Neem and Pawpaw leaf extract

Abstract:

Tumor suppression by the extracts of Azadirachta indica (neem) works via anti-proliferation, cell cycle arrest, and apoptosis, demonstrated previously using cancer cell lines and live animal models. However, very little is known about the molecular targets and pathways that neem extracts and their associated compounds act through. Here, we address this using a genome-wide functional pooled shRNA screen on head and neck squamous cell carcinoma cell lines treated with crude neem leaf extracts, known for their anti-tumorigenic activity. We analyzed differences in global clonal sizes of the shRNA-
