Frank J. Slack, PhD
Dr. Frank Slack is the Shields Warren Mallinckrodt Professor, Department of Pathology, and Director of the Institute for RNA Medicine, BIDMC. He received his BSc from the University of Cape Town in South Africa before completing his PhD in molecular biology at Tufts University School of Medicine. He began work on microRNAs as a postdoctoral fellow in Gary Ruvkun’s laboratory at Harvard Medical School, where he co-discovered the second known microRNA, let-7.
The Slack laboratory is at the forefront of the small RNA revolution. They co-discovered the first human microRNA, let-7 and showed that it is a tumor suppressor that controls key cancer genes, such as RAS, MYC and LIN28. They are developing let-7 and a second microRNA, miR-34 as novel cancer therapeutics with miR-34 already in Phase I clinical trials. They also proved that microRNAs act as key oncogenes and developed strategies to target these oncomiRs for cancer therapy. Their research also extends to discovery of additional novel small RNAs in development, cancer, aging and diabetes as well as identifying novel SNPs in the non-coding portions of the genome with an eye to identifying the next generation of actionable targets in cancer.
About the Slack Lab
The past decade has brought about a paradigm shift in how the scientiﬁc community views gene regulation, and we are thrilled to be at the vanguard of this biological revolution. Non-coding regulatory RNAs direct such diverse processes as gene silencing, transcriptional and translational control, imprinting and dosage compensation. These discoveries have electriﬁed the biological community as we try to understand the extent of the “RNA world” and to harness these new molecules in medicine . One class of regulatory RNAs leading the charge in this revolution are the microRNAs (miRNAs). MiRNAs are recently discovered regulatory molecules that control a large variety of biological processes including development, metabolism and aging [2-4]. The Slack lab co-discovered the second known miRNA and the ﬁrst human miRNA [5, 6]. Since then, hundreds of miRNAs have been identiﬁed in worm, ﬂy, and mammalian genomes, However, the biological roles of only a small fraction of these miRNAs have been characterized. Members of the Slack lab have continued to push the boundaries of this exciting ﬁeld by, for example, discovering roles for microRNAs in cancer and aging [7, 8] and in translating these discoveries to the clinic as potential cures and biomarkers for cancer and aging [9-12].
