Question: Paragraph: CD133 (prominin-1), a 5-transmembrane glycoprotein, has recently been considered to be an important marker that represents the subset population of cancer stem-like cells. Herein we report the isolation of CD133-positive cells (LC-CD133 + ) and CD133-negative cells (LC-CD133 2 ) from tissue samples of ten patients with non-small cell lung cancer (LC) and five LC cell lines. LC-CD133 + displayed higher Oct-4 expressions with the ability to self-renew and may represent a reservoir with proliferative potential for generating lung cancer cells. Furthermore, LC-CD133 + , unlike LC-CD133 2 , highly coexpressed the multiple drug-resistant marker ABCG2 and showed significant resistance to chemotherapy agents (i.e., cisplatin, etoposide, doxorubicin, and paclitaxel) and radiotherapy. The treatment of Oct-4 siRNA with lentiviral vector can specifically block the capability of LC-CD133 + to form spheres and can further facilitate LC-CD133 + to differentiate into LC-CD133 2 . In addition, knock-down of Oct-4 expression in LC-CD133 + can significantly inhibit the abilities of tumor invasion and colony formation, and increase apoptotic activities of caspase 3 and poly (ADP-ribose) polymerase (PARP). Finally, in vitro and in vivo studies further confirm that the treatment effect of chemoradiotherapy for LC-CD133 + can be improved by the treatment of Oct-4 siRNA. In conclusion, we demonstrated that Oct-4 expression plays a crucial role in maintaining the self-renewing, cancer stem-like, and chemoradioresistant properties of LC-CD133 + . Future research is warranted regarding the up-regulated expression of Oct-4 in LC-CD133 + and malignant lung cancer.

Answer: True


Question: Paragraph: Norovirus infection constitutes the primary cause of acute viral gastroenteritis. There are currently no vaccines or norovirus-specific antiviral therapeutics available for the management of norovirus infection. Norovirus 3C-like protease is essential for viral replication, consequently, inhibition of this enzyme is a fruitful avenue of investigation that may lead to the emergence of anti-norovirus therapeutics. We describe herein the optimization of dipeptidyl inhibitors of norovirus 3C-like protease using iterative SAR, X-ray crystallographic, and enzyme and cell-based studies. We also demonstrate herein in vivo efficacy of an inhibitor using the murine model of norovirus infection. . Accession Codes. The coordinates and structure factors for norovirus 3CL protease in complex with inhibitors have been deposited to the Protein Databank with the accession codes NVpro:17 (4XBB), NVPro:44-h (4XBC) and NVPro:44-o (4XBD). We initially focused on the design of peptidyl transition state inhibitors of NV 3CLpro that incorporate in their structure a recognition element (a peptidyl fragment) that is congruent with the known substrate specificity of the enzyme (vide supra) and a warhead (aldehyde or α-ketoamide), latent warhead (bisulfite adduct) or transition state mimic (α- Kankanamalage et al. The synthesized compounds were evaluated for their inhibitory activity against NV 3CLpro, as well as their anti-norovirus activity in a cell-based replicon system, as previously Kankanamalage et al. In order to evaluate the specific interactions between the enzyme and the αhydroxyphosphonate inhibitors, inhibitor 17 was incubated with NV 3CLpro in Tris buffer, pH 8.0. Surprisingly, the enzyme-inhibitor complex formed corresponded to the complex formed between aldehyde 16 and 3CL protease. The formation of this complex indicates initial non-enzymatic (buffer)-or enzyme-catalyzed conversion of α-hydroxyphosphonate 17 to the corresponding aldehyde 16, followed by the formation of a tetrahedral adduct with the active site cysteine (Cys139). Studies aimed at ascertaining the validity of this hypothesis are in progress. The ensemble of hydrogen bonding and hydrophobic interactions Kankanamalage et al.

Answer: False


Question: Paragraph: Coronaviruses infect animals and humans causing a wide range of diseases. The diversity of coronaviruses in many mammalian species is contributed by relatively high mutation and recombination rates during replication. This dynamic nature of coronaviruses may facilitate cross-species transmission and shifts in tissue or cell tropism in a host, resulting in substantial change in virulence. Feline enteric coronavirus (FECV) causes inapparent or mild enteritis in cats, but a highly fatal disease, called feline infectious peritonitis (FIP), can arise through mutation of FECV to FIP virus (FIPV). The pathogenesis of FIP is intimately associated with immune responses and involves depletion of T cells, features shared by some other coronaviruses like Severe Acute Respiratory Syndrome Coronavirus. The increasing risks of highly virulent coronavirus infections in humans or animals call for effective antiviral drugs, but no such measures are yet available. Previously, we have reported the inhibitors that target 3C-like protease (3CLpro) with broad-spectrum activity against important human and animal coronaviruses. Here, we evaluated the therapeutic efficacy of our 3CLpro inhibitor in laboratory cats with FIP. Experimental FIP is 100% fatal once certain clinical and laboratory signs become apparent. We found that antiviral treatment led to full recovery of cats when treatment was started at a stage of disease that would be otherwise fatal if left untreated. Antiviral treatment was associated with a rapid improvement in fever, ascites, lymphopenia and gross signs of illness and cats returned to normal health within 20 days or less of treatment. Significant reduction in viral titers was also observed in cats. These results indicate that continuous virus replication is required for progression of immune-mediated inflammatory disease of FIP. These findings may provide important insights into devising therapeutic strategies and selection of antiviral compounds for further development for important coronaviruses in animals and humans.
