Receptors for bone morphogenetic proteins (BMPs), members of the transforming growth factor-beta (TGFbeta) superfamily, are persistently expressed during cardiac development, yet mice lacking type II or type IA BMP receptors die at gastrulation and cannot be used to assess potential later roles in creation of the heart. Here, we used a Cre/lox system for cardiac myocyte-specific deletion of the type IA BMP receptor, ALK3. ALK3 was specifically required at mid-gestation for normal development of the trabeculae, compact myocardium, interventricular septum, and endocardial cushion. Cardiac muscle lacking ALK3 was specifically deficient in expressing TGFbeta2, an established paracrine mediator of cushion morphogenesis. Hence, ALK3 is essential, beyond just the egg cylinder stage, for myocyte-dependent functions and signals in cardiac organogenesis.

Akli S, Zhan S, Abdellatif M, et al., 1999, E1A can provoke G1 exit that is refractory to p21 and independent of activating cdk2., Circ Res, Vol: 85, Pages: 319-328, ISSN: 0009-7330
E1A can evoke G1 exit in cardiac myocytes and other cell types by displacing E2F transcription factors from tumor suppressor "pocket" proteins and by a less well-characterized p300-dependent pathway. Bypassing pocket proteins (through overexpression of E2F-1) reproduces the effect of inactivating pocket proteins (through E1A binding); however, pocket proteins associate with a number of molecular targets apart from E2F. Hence, pocket protein binding by E1A might engage mechanisms for cell cycle reentry beyond those induced by E2F-1. To test this hypothesis, we used adenoviral gene transfer to express various E2F-1 and E1A proteins in neonatal rat cardiac myocytes that are already refractory to mitogenic serum, in the absence or presence of several complementary cell cycle inhibitors-p16, p21, or dominant-negative cyclin-dependent kinase-2 (Cdk2). Rb binding by E2F-1 was neither necessary nor sufficient for G1 exit, whereas DNA binding was required; thus, exogenous E2F-1 did not merely function by competing for the Rb "pocket." E2F-1-induced G1 exit was blocked by the "universal" Cdk inhibitor p21 but not by p16, a specific inhibitor of Cdk4/6; p21 was permissive for E2F-1 induction of cyclins E and A, but prevented their stimulation of Cdk2 kinase activity. In addition, E2F-1-induced G1 exit was blocked by dominant-negative Cdk2. Forced expression of cyclin E induced endogenous Cdk2 activity but not G1 exit. Thus, E2F-1-induced Cdk2 function was necessary, although not sufficient, to trigger DNA synthesis in cardiac muscle cells. In contrast, pocket protein-binding forms of E1A induced G1 exit that was resistant to inhibition by p21, whereas G1 exit via the E1A p300 pathway was sensitive to inhibition by p21. Both E1A pathways-via pocket proteins and via p300-upregulated cyclins E and A and Cdk2 activity, consistent with a role for Cdk2 in G1 exit induced by E1A. However, p21 blocked Cdk2 kinase activity induced by both E1A pathways equa
Abdellatif M, Packer SE, Michael LH, et al., 1998, A Ras-dependent pathway regulates RNA polymerase II phosphorylation in cardiac myocytes: implications for cardiac hypertrophy., Mol Cell Biol, Vol: 18, Pages: 6729-6736, ISSN: 0270-7306
Despite extensive evidence implicating Ras in cardiac muscle hypertrophy, the mechanisms involved are unclear. We previously reported that Ras, through an effector-like function of Ras GTPase-activating protein (GAP) in neonatal cardiac myocytes (M. Abdellatif et al., J. Biol. Chem. 269:15423-15426, 1994; M. Abdellatif and M. D. Schneider, J. Biol. Chem. 272:527-533, 1997), can up-regulate expression from a comprehensive set of promoters, including both cardiac cell-specific and constitutive ones. To investigate the mechanism(s) underlying these earlier findings, we have used recombinant adenoviruses harboring a dominant negative Ras (17N Ras) allele or the N-terminal domain of GAP (nGAP), responsible for the Ras-like effector function. Inhibition of endogenous Ras reduced basal levels of [3H]uridine and [3H]phenylalanine incorporation into total RNA, mRNA, and protein, with parallel changes in apparent cell size. In addition, 17N Ras markedly inhibited phosphorylation of the C-terminal domain (CTD) of RNA polymerase II (pol II), known to regulate transcript elongation, accompanied by down-regulation of its principal kinase, cyclin-dependent kinase 7 (Cdk7). In contrast, nGAP elicited the opposite effects on each of these parameters. Furthermore, cotransfection of constitutively active Ras (12R Ras) with wild-type pol II, rather than a truncated mutant lacking the CTD, demonstrated that Ras activation of transcription was dependent on the pol II CTD. Consistent with a potential role for this pathway in the development of cardiac myocyte hypertrophy, alpha1-adrenergic stimulation similarly enhanced pol II phosphorylation and Cdk7 expression, where both effects were inhibited by dominant negative Ras, while pressure overload hypertrophy led to an increase in both hyperphosphorylated and hypophosphorylated pol II in addition to Cdk7.
Charng MJ, Frenkel PA, Lin Q, et al., 1998, A constitutive mutation of ALK5 disrupts cardiac looping and morphogenesis in mice., Dev Biol, Vol: 199, Pages: 72-79, ISSN: 0012-1606
TGF beta family members are implicated in cardiac organogenesis, growth control, and positional information, including the direction of cardiac looping. However, genetic analysis of TGF beta signaling in mice has been confounded, in some cases, by noncardiac and generalized defects. Hence, deciphering TGF beta function in myocardium would benefit from cardiac-restricted mutations. We developed a constitutively activated type I receptor, ALK5L193A,P194A,T204D, and directed it to embryonic myocardium in transgenic mice. Expression of the activated ALK5 gene arrests looping morphogenesis and causes a linear, dilated, hypoplastic heart tube, despite normal expression of Nkx2.5 and dHAND, cardiogenic transcription factors whose absence provokes a similar phenotype. Ventricular hypoplasia was associated with precocious induction of the cyclin-dependent kinase inhibitor, p21. Thus, an ALK5-sensitive pathway mediates looping, perhaps through control of cardiac myocyte proliferation.
Charng MJ, Zhang D, Kinnunen P, et al., 1998, A novel protein distinguishes between quiescent and activated forms of the type I transforming growth factor beta receptor., J Biol Chem, Vol: 273, Pages: 9365-9368, ISSN: 0021-9258
Transforming growth factor beta (TGFbeta) signal transduction is mediated by two receptor Ser/Thr kinases acting in series, type II TGFbeta receptor (TbetaR-II) phosphorylating type I TGFbeta receptor (TbetaR-I). Because the failure of interaction cloning, thus far, to identify bona fide TbetaR-I substrates might reasonably have been due to the use of inactive TbetaR-I as bait, we sought to identify molecules that interact specifically with active TbetaR-I, employing the triple mutation L193A,P194A,T204D in a yeast two-hybrid system. The Leu-Pro substitutions prevent interaction with FK506-binding protein 12 (FKBP12), whose putative function in TGFbeta signaling we have previously disproved; the charge substitution at Thr204 constitutively activates TbetaR-I. Unlike previous screens using wild-type TbetaR-I, where FKBP12 predominated, none of the resulting colonies encoded FKBP12. A novel protein was identified, TbetaR-I-associated protein-1 (TRAP-1), that interacts in yeast specifically with mutationally activated TbetaR-I, but not wild-type TbetaR-I, TbetaR-II, or irrelevant proteins. In mammalian cells, TRAP-1 was co-precipitated only by mutationally activated TbetaR-I and ligand-activated TbetaR-I, but not wild-type TbetaR-I in the absence of TGFbeta. The partial TRAP-1 protein that specifically binds these mutationally and ligand-activated forms of TbetaR-I can inhibit signaling by the native receptor after stimulation with TGFbeta or by the constitutively activated receptor mutation, as measured by a TGFbeta-dependent reporter gene. Thus, TRAP-1 can distinguish activated forms of the receptor from wild-type receptor in the absence of TGFbeta and may potentially have a functional role in TGFbeta signaling.
