As for many biomedical, basic-science research labs, my research flows and changes over time as we make new discoveries that lead us to new questions we form even as we uncover the answers to previous questions. That is the nature of basic science, and it is the way science investigation has always brought the most benefits to people and medicine in particular. While many organizations and countries have attempted to focus research support (funding) into specific diseases, it turns out that the overwhelming majority of high-impact medical discoveries have come from “serendipity”. That is, great useful ideas and tools were discovered to treat diseases simply by exploring how things work.
For example, drugs for controlling high cholesterol were not discovered by deciding to start making drugs for treating high cholesterol. In the course of biochemists investigating how our cells make cholesterol in the first place, chemicals were used to block enzymes to help figure out how cholesterol was made. Some of these chemicals were obviously the idea to become new drugs that could block cholesterol made in the body. Latanoprost, one of the later generation of drugs developed in the ’80s for reducing high intraocular pressure (IOP), was based on the discovery that prostaglandins made by some cells in the eye could increase the aqueous outflow in the eye, and reduce pressure. The basic science was elucidated in animal models. Again, a basic science discovery in the laboratory of physiologist Laszlo Bito at Columbia University was adopted by a Pharma company as the way to make drugs that mimic natural prostaglandins to produce this new class of drugs. As a result, thousands of people around the world have another class of drugs to reduce their intraocular pressure and reduce their risk of vision loss from Glaucoma.
So, you never really know where benefits will arise for biomedicine. That is why many research funding agencies, such as the NIH (USA) and the MRC (UK), understand the importance of funding physiologists and biochemists to explore how things work. In our case, how things work in the eye, and the retina of the eye.
