Lead is a naturally occurring metal that has been used extensively throughout history. Its usage is traced right back to ancient history. High exposure to lead, particularly in young children, is associated with health complications. Lead poisoning is not a new phenomenon. Reports of lead poisoning from water pipes and wine containers date back to Roman times.
Researchers have discovered that two plant stem cell proteins physically interact and regulate each other to prevent cellular division.
A research team from Brazil and Portugal has identified a link between a microRNA (miRNA) and the presence of lead in an organism.
Researchers have revealed a connection between methylation of genes implicated in heme synthesis and carcinogenesis and high blood lead levels in children, signifying a previously unfamiliar mechanism for lead poisoning.
