Conus ''Conus'' is a genus of venomous and predatory cone snails.Bouchet, P.; Gofas, S. (2015). Conus Linnaeus, 1758. In: MolluscaBase (2015). Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&i ...
marine snails. Throughout the Philippines, she is known as the ''Sea Snail Venom Specialist.'' The characterization of over 50 biologically active peptides from the snail's venom had been made possible, in part, by her studies. Scientific findings regarding the peptides found in snails have applications in diagnostic tools for cancers and the development of drugs for the treatment of neurological disorders. She has also contributed to the development of

Research

Cruz has published over 130 academic papers and as a prolific career in research. In 1970, Cruz worked as an assistant professor at the University of the Philippines College of Medicine. She worked with many biochemists and began her research on ''

,'' a venomous fish-hunting cone snail found in the waters of Marinduque and Mindoro of the Philippines whose sting can result in death in humans. Her work focused on the isolation of peptides from the conotoxins in the snail's venom while their effects were still unknown. Her research shed light on the effects of conotoxins on the central nervous system and their connection to muscular paralysis, sleepiness, or drowsiness, involuntary motion and more. Today, conotoxin peptides are very important and they are extensively used biochemical probes such as to test calcium channels in neurons and prohibitory of muscular movement when investigation actions at synapses. For example, two classes of conotoxins are used as analytical agents: ω-conotoxin has been widely used for studying neuronal

s and μ-conotoxin has been used when controlling muscular activity to observe events at the synapse. Cruz has also pursued research in connecting science and technology to poor and indigenous rural communities. In 2001, she launched an initiative called the Rural LINC Program which allowed indigenous women in the Philippines to work at a fruit-processing plant in order to combat poverty. Additionally, she currently serves as the project leader for the Future Earth Philippines Program, an effort to reduce unsustainable practices like deforestation, coral reef degradation, pollution, and irresponsible mining and agriculture in the Philippines.
