Choroid Plexus Tumor Drug Discovery Service
Choroid plexus tumors are rare primary epithelial brain tumors arising in the ventricle, which are characterized by nuclear pleomorphism, blurring of the papillary pattern, necrosis, and high nucleus-to-cytoplasm ratios. It has been classified into 3 histological grades, namely more benign choroid plexus papilloma (CPP), aggressive choroid plexus carcinoma (CPC), and atypical choroid plexus papilloma (aCPP). Although they can be surgically removed, choroid plexus tumors usually spread along the neuraxis and recur after operation and treatment.
Due to the scarcity of study populations, the tumorigenesis and the best treatment regimen for choroid plexus tumors remain undefined. Creative Biolabs has accumulated years of experience and integrated global resources in the field of neuroscience. Our one-stop solutions for choroid plexus tumors allow researchers and developers to investigate the pathogenesis of choroid plexus tumors, and thus develop promising therapies.
Mechanism of Action Studies of Choroid Plexus Tumor
The MoA studies of choroid plexus tumors remain undetermined. Genetic alterations are involved in the pathogenesis of children and adult choroid plexus tumors including, frequent numerical aneuploidy, TP53 tumor suppressor gene alterations, TERT promoter mutations, DNA methylation in AK1, PER2, and PLSCR4, the gain of chromosome 5, and a novel CCDC47-PRKCA gene fusion (Pienkowska, 2019; Thomas, 2021). Gamma-aminobutyric acid (GABA) is a tumor-signaling molecule in the central and peripheral nervous systems. GABA together with its receptors is involved in tumor cell proliferation in choroid plexus tumors. The alteration of circadian rhythms potentially leads to increased susceptibility to cancer in humans. It has been investigated that GABA regulation and AMP-activated protein kinase (AMPK) are important in circadian rhythms. In addition, c-MYC overexpression induces CPP through a T-cell-mediated inflammatory mechanism (Merve, 2019). The MoA studies of choroid plexus tumors remain undetermined. Scientists at Creative Biolabs are dedicated to providing you with choroid plexus tumor expertise and help to explore the underlying mechanisms for further drug discovery.
