Tumors often exhibit activation of specific tyrosine kinases, which may allow targeting of therapy through inhibition of tyrosine kinase signaling. This strategy has been used successfully in the development of STI571 (gleevec), an inhibitor of bcr-abl tyrosine kinase that has been used successfully
BACKGROUND
An increased understanding of the genetic pathways involved in renal cell carcinoma has resulted in the development of various drugs that target relevant signaling cascades for the specific treatment of this disease. However, no validated predictive markers have been identified to guide
Everolimus, an oral inhibitor of the mammalian target of rapamycin (mTOR) pathway, is currently approved for treatment of advanced renal-cell carcinoma (RCC) after failure of initial treatment with the tyrosine kinase inhibitors. Patients with tuberous sclerosis complex (TSC) syndrome can also
Tuberous sclerosis complex 1 (TSC1) and TSC2 tumor suppressor proteins have been shown to negatively regulate cell growth through inhibition of the mammalian target of rapamycin (mTOR) pathway. Focal adhesion kinase (FAK) is a cytoplasmic tyrosine kinase that plays a critical role in integrin
AMP-activated protein kinase (AMPK) inhibits IGF-I actions, but the mechanism by which AMPK functions is undefined. This study identified signaling events that were induced by AMPK that mediated inhibition of IGF-I-stimulated phosphoinosotide-3-kinase (PI3K) pathway activation. The AMPK activator
Tuberous Sclerosis Complex (TSC) is a rare genetic disease that manifests with early symptoms, including cortical malformations, childhood epilepsy, and TSC-associated neuropsychiatric disorders (TANDs). Cortical malformations arise during embryonic development and have been linked to childhood
Hamartin and tuberin are products of the tumor suppressor genes, TSC1 and TSC2, respectively. When mutated, a characteristic spectrum of tumor-like growths develop resulting in the syndrome of tuberous sclerosis complex. The phenotypes associated with TSC1 and TSC2 mutations are largely
OBJECTIVE
Malignant astrocytomas exhibit constitutive Akt phosphorylation due to reduced phosphatase and tensin homologue (PTEN) tumor suppressor expression or to increased growth factor receptor tyrosine kinase activation. Many astrocytomas are also tuberous sclerosis complex 2 (TSC2) protein
Renal cell carcinoma (RCC) is among the most prevalent malignancies in the USA. Most RCCs are sporadic, but hereditary syndromes associated with RCC account for 2-3 % of cases and include von Hippel-Lindau, hereditary leiomyomatosis, Birt-Hogg-Dube, tuberous sclerosis, hereditary papillary RCC, and
Pancreatic neuroendocrine tumours (PETs) are the second most frequent pancreatic neoplasms. Their poor chemosensitivity, high rate of metastatic disease and relatively long survival make PETs an ideal field to be explored for novel therapies based on specific molecular changes. PETs are generally
BACKGROUND
OMICS is the term used to designate new biological sciences investigating a large group of molecules in biological samples. For instance, genomics and transcriptomics study changes in genome and transcription expression respectively. Numerous others OMICS are emerging (e.g. epigen-,
OBJECTIVE
The objective of this analysis is to review a spectrum of functional brain imaging technologies to identify whether there are any imaging modalities that are more effective than others for various brain pathology conditions. This evidence-based analysis reviews magnetoencephalography
Renal cell carcinoma (RCC) has the highest rate of occurrence within the US when compared with other countries. Recent advances in the basic research and molecular diagnostics of this malignancy have revealed that RCC is not a single disease, but it is a mixture of several types of malignancies with
EGFR belongs to the HER/ErbB family of tyrosine kinase receptors and its activation in cancer cells has been linked with increased proliferation, angiogenesis, and metastasis. Lymphangioleiomyomatosis (LAM) is a rare, low-grade neoplasm that occurs sporadically or in association with tuberous
