The goal of this work is to understand the genetic and molecular mechanisms leading to disorders that affect the adrenal cortex, with emphasis on those that are developmental, hereditary and associated with adrenal hypoplasia or hyperplasia, multiple tumors and abnormalities in other endocrine glands (especially the pituitary gland and to a lesser extent the thyroid gland). We have studied congenital adrenal hypoplasia caused by triple A syndrome and other defects, other multiple endocrine deficiencies, familial hyperaldosteronism, adrenocortical and thyroid cancer, pituitary tumors and multiple endocrine neoplasia (MEN) syndromes affecting the pituitary, thyroid and adrenal glands, and Carney complex (CNC), an autosomal dominant disease. CNC is a MEN syndrome affecting the pituitary, adrenal cortex, thyroid, and the gonads, and is associated with a variety of other tumors, including myxomas and schwannomas, and skin pigmentation defects (lentigines, cafe-au-lait spots, and nevi). We have identified the regulatory subunit type 1-A of protein kinase A (PKA), which is coded by the PRKAR1A gene as the gene responsible for most CNC patients. Thus, a significant part of our work is now focused on PKA-stimulated signaling pathways, PKA effects on tumor suppression and/or development, the cell cycle and chromosomal stability. Prkar1a-specific animal models have also been created to address the tumor-promoting effects of this gene and serve as models for possible therapies. In addition, genes that are mutated in patients with CNC-like and other froms of inherited adrenal tumors are being investigated. Most recently, mutations in a phosphodiesterase genes - phosphodiesterase 11A (PDE11A) and PDE8B - were identified in patients with bilateral adrenocortical hyperplasia. A mouse model of PDE11A deficiency is being studied, and mutations of this gene are being sought in other endocrine tumors. We also started the effort to generate a mouse model for PDE8B. Most recently, we have elucidated the causative genetic defects in Carney-Stratakis syndrome (CSS) and we have embarked on a new search for genes that are related to tumors that develop in association with CSS and a similar condition (Carney Triad).

这项工作的目的是了解导致影响肾上腺皮质的疾病的遗传和分子机制，重点是那些发育，遗传性和与肾上腺低质或增生相关的疾病，多种肿瘤和多种肿瘤和异常（尤其是垂体腺体的垂体和垂体症状较小）。我们研究了由三倍A综合征和其他缺陷，其他多种内分泌缺陷，家族性大甲醛酸，高甲状腺质体，肾上腺皮质和甲状腺癌，垂体肿瘤，垂体肿瘤以及多个内分泌肿瘤（MEN）综合症影响垂体，脑症和肾上腺疾病的综合体和CARNEAL GLANDEN综合体，以及Carney Antrande rander rander rander rander，我们研究了先天性肾上腺低质性急症低位症。 疾病。 CNC是一种男性综合征，影响垂体，肾上腺皮质，甲状腺和性腺，并且与其他多种肿瘤有关，包括粘液瘤和schwannomas，以及皮肤色素沉着缺陷（夹犬，Cafe-au-au-lait Spots和Nevi）。我们已经确定了由PRKAR1A基因编码的蛋白激酶A（PKA）的调节亚基1-A型，是负责大多数CNC患者的基因。因此，我们工作的很大一部分现在集中在PKA刺激的信号通路上，PKA对肿瘤抑制和/或发育的影响，细胞周期和染色体稳定性。还创建了PRKAR1A特异性动物模型来解决该基因的肿瘤促进作用，并用作可能疗法的模型。此外，正在研究中CNC样患者突变的基因和其他遗传性肾上腺肿瘤的基因。最近，在双侧肾上腺皮质增生的患者中发现了磷酸二酯酶基因的突变 - 磷酸二酯酶11A（PDE11A）和PDE8B。正在研究PDE11A缺乏的小鼠模型，并在其他内分泌肿瘤中寻求该基因的突变。我们还开始努力为PDE8B生成鼠标模型。最近，我们阐明了Carney-STRATAKIS综合征（CSS）中的致病遗传缺陷，并且已经开始了与与CSS相关的肿瘤和相似疾病（Carney Triad）相关的肿瘤相关的基因的新搜索（Carney Triad）。
