Agata Smogorzewska is a Polish-born scientist. She is an associate professor at Rockefeller University, heading the Laboratory of Genome Maintenance. [1] [2] Her work primarily focuses on DNA interstrand crosslink repair and the diseases resulting from deficiencies in this repair pathway, including Fanconi anemia and karyomegalic interstitial nephritis. [3] [4]
After finishing high school in Poland, [5] Smogorzewska completed her bachelor of science in molecular biology and biochemistry in 1995 at the University of Southern California. [3] She then went on to enroll in the tri-institutional M.D., Ph.D. program of Weill Cornell, Rockefeller and Sloan Kettering, finishing her Ph.D. thesis studies on the functions of the telomeric protein, TRF2, in the lab of Dr. Titia de Lange at Rockefeller University in 2002, and her medical degree from Weill Cornell in 2003. [3] [4] [5] Smogorzewska then went on to a residency in clinical pathology at the Massachusetts General Hospital from 2003–2006, becoming a postdoctoral researcher at Harvard Medical School between 2005–2009 under Dr. Stephen Elledge where she discovered the Fanconi anemia protein FANCI. [3] [4]
Smogorzewska became an assistant professor at Rockefeller University in 2009 and was subsequently elevated to associate professor in 2015. [3] Her lab focuses on DNA repair mechanisms, particularly the interstrand crosslink repair pathway, which concerns the cellular mechanisms by which the two strands of DNA that have been covalently linked are excised, creating a double strand DNA break that is subsequently processed by factors in the Fanconi anemia and homologous recombination pathways. [3] [4] In particular, Smogorzewska is interested in identifying new genes that are involved in this repair process in order to reveal the mechanisms at play in human diseases that result from deficiencies in interstrand crosslink repair, including Fanconi anemia and karyomegalic interstitial nephritis. [3] [4] To this end, Smogorzewska has successfully identified SLX4, RAD51 and UBE2T as interstrand crosslink repair factors, as well as developed a mouse model of karyomegalic interstitial nephritis. [3] Recently, Smogorzewska has begun studies revolving around how replication stress is addressed by cells to promote genome stability. [4]

Fanconi anaemia (FA) is a rare, AR, genetic disease resulting in impaired response to DNA damage in the FA/BRCA pathway. Although it is a very rare disorder, study of this and other bone marrow failure syndromes has improved scientific understanding of the mechanisms of normal bone marrow function and development of cancer. Among those affected, the majority develop cancer, most often acute myelogenous leukemia (AML), MDS, and liver tumors. 90% develop aplastic anemia by age 40. About 60–75% have congenital defects, commonly short stature, abnormalities of the skin, arms, head, eyes, kidneys, and ears, and developmental disabilities. Around 75% have some form of endocrine problem, with varying degrees of severity. 60% of FA is FANC-A, 16q24.3, which has later onset bone marrow failure.
Telomeric repeat-binding factor 2 is a protein that is present at telomeres throughout the cell cycle. It is also known as TERF2, TRF2, and TRBF2, and is encoded in humans by the TERF2 gene. It is a component of the shelterin nucleoprotein complex and a second negative regulator of telomere length, playing a key role in the protective activity of telomeres. It was first reported in 1997 in the lab of Titia de Lange, where a DNA sequence similar, but not identical, to TERF1 was discovered, with respect to the Myb-domain. De Lange isolated the new Myb-containing protein sequence and called it TERF2.
Telomeric repeat-binding factor 1 is a protein that in humans is encoded by the TERF1 gene.
Fanconi anemia group D2 protein is a protein that in humans is encoded by the FANCD2 gene. The Fanconi anemia complementation group (FANC) currently includes FANCA, FANCB, FANCC, FANCD1, FANCD2, FANCE, FANCF, FANCG, FANCI, FANCJ, FANCL, FANCM, FANCN and FANCO.
ERCC4 is a protein designated as DNA repair endonuclease XPF that in humans is encoded by the ERCC4 gene. Together with ERCC1, ERCC4 forms the ERCC1-XPF enzyme complex that participates in DNA repair and DNA recombination.
Fanconi anemia group F protein is a protein that in humans is encoded by the FANCF gene.
E3 ubiquitin-protein ligase FANCL is an enzyme that in humans is encoded by the FANCL gene.
Fanconi anemia group B protein is a protein that in humans is encoded by the FANCB gene.
Fanconi anemia, complementation group I (FANCI) also known as KIAA1794, is a protein which in humans is encoded by the FANCI gene. Mutations in the FANCI gene are known to cause Fanconi anemia.
DNA cross-link repair 1B protein is a protein that in humans is encoded by the DCLRE1B gene.
Fanconi anemia, complementation group M, also known as FANCM is a human gene. It is an emerging target in cancer therapy, in particular cancers with specific genetic deficiencies.
SLX4 is a protein involved in DNA repair, where it has important roles in the final steps of homologous recombination. Mutations in the gene are associated with the disease Fanconi anemia.
Telomere-binding proteins function to bind telomeric DNA in various species. In particular, telomere-binding protein refers to TTAGGG repeat binding factor-1 (TERF1) and TTAGGG repeat binding factor-2 (TERF2). Telomere sequences in humans are composed of TTAGGG sequences which provide protection and replication of chromosome ends to prevent degradation. Telomere-binding proteins can generate a T-loop to protect chromosome ends. TRFs are double-stranded proteins which are known to induce bending, looping, and pairing of DNA which aids in the formation of T-loops. They directly bind to TTAGGG repeat sequence in the DNA. There are also subtelomeric regions present for regulation. However, in humans, there are six subunits forming a complex known as shelterin.
Simon Joseph Boulton is a British scientist who has made important contributions to the understanding of DNA repair and the treatment of cancer resulting from DNA damage. He currently occupies the position of Senior Scientist and group leader of the DSB Repair Metabolism Laboratory at the Francis Crick Institute, London. He is also an honorary Professor at University College London.
Shelterin is a protein complex known to protect telomeres in many eukaryotes from DNA repair mechanisms, as well as to regulate telomerase activity. In mammals and other vertebrates, telomeric DNA consists of repeating double-stranded 5'-TTAGGG-3' (G-strand) sequences along with the 3'-AATCCC-5' (C-strand) complement, ending with a 50-400 nucleotide 3' (G-strand) overhang. Much of the final double-stranded portion of the telomere forms a T-loop (Telomere-loop) that is invaded by the 3' (G-strand) overhang to form a small D-loop (Displacement-loop).
