Table 2: Leader Genes and their Established or Putative Role in Periodontitis and Human Heart Ischemia. NFKB1, the Shared Leader Gene is Represented in Bold

Periodontitis Heart Ischemia
Gene Symbol Gene Name Role Gene Symbol Gene Name Role
NFKB1 nuclear factor of kappa light polypeptide gene enhancer in B-cells 1 Increased activity beneath periodontal lesions TP53 tumor protein p53 Induces apoptosis of cardiac myocytes
CBL v-rel reticuloendotheliosis viral oncogene homolog A (avian) Triggering of inflammation NFKB1 nuclear factor of kappa light polypeptide gene enhancer in B-cells 1 Some polymorphisms are associated to heart dysfunction
Triggering of inflammation
GRB2 phosphoinositide-3-kinase, regulatory subunit 1 (alpha) Marker of severe periodontitis BCL2 B-cell CLL/lymphoma 2 Protection of myocytes from apoptosis
PIK3R1 growth factor receptor-bound protein 2 Possible involvement in growth and differentiation in periodontal tissues, via the EGFR/RAS signalling MAPK3 mitogen-activated protein kinase 3 Protection of myocytes from apoptosis
RELA Cas-Br-M (murine) ecotropic retroviral transforming sequence Possible involvement in bone resorption MAPK1 mitogen-activated protein kinase 1 Protection of myocytes from apoptosis
SRC v-src sarcoma (Schmidt-Ruppin A-2) viral oncogene homolog (avian) Induces apoptosis of cardiac myocytes
