“Introduction Bladder cancer is the fourth most common cancer in men after prostate, lung, and colorectal cancers, accounting for 7% of all cancer case [1]. The majority of bladder tumors (75%) are non muscle-invasive at diagnosis and after local surgical therapy, have a high risk of recurrence and a propensity to progress in grade or stage [2]. At present, its major treatment is surgical removal but, with surgical approach, recurrence tends to take place. this website Muscle invasive tumors (25%) have a poorer prognosis [3] since 50% of patients will

relapse with metastatic disease within 2 years of treatment. Patients presenting https://www.selleckchem.com/products/sch-900776.html with muscle invasive cancer or progressing to this stage have Pyruvate dehydrogenase a poor survival rate, despite receiving conventional therapies [4]. With the development of the molecular biology, genes involved in tumorigenesis have been targeted for the treatment of tumor. Epidermal growth factor receptor(EGFR) is a transmembrane protein tyrosine

kinase and over-expressed or activated in a variety of malignant lesions, including bladder cancer [5]. Over-expressed or activated EGFR signaling is the initial step of a cascade of events leading to tumor cell proliferation, invasion, migration and evasion of apoptosis [6, 7]. Inhibition of EGFR by different approaches causes increased apoptosis and sensitizes tumor cells to radiation therapy and chemical therapy [8, 9]. Owing to the important role of the EGFR activation in bladder cancer growth and progression, therefore, it is a potential target for molecular therapy for invasive bladder cancer. The human LRIG gene family comprises three paralogous genes, namely LRIG1 (formerly LIG1) [10], LRIG2 [11] and LRIG3 [12]. Leucine-rich repeats and immunoglobulin-like domains 1(LRIG1) is a transmenbrane leucine-rich repeat and immunoglobulin(Ig)-like domain-containing protein, whose transcript is located at chromosome 3p14.3, a region frequently deleted in various types of human cancers [10]. It is capable of interacting with EGFR and enhancing both its basal and ligand-stimulated ubiquitination and degradation [13, 14].
