Figure Legend Snippet:
Techniques Used: shRNA, Plasmid Preparation
Figure Legend Snippet: CD46 and CD55 mRNA expression levels were measured using qRT-PCR in both AML and ALL patients, normalized to the housekeeping gene Beta-actin and results were compared to CD46 and CD55 mRNA expression levels in healthy controls by calculating the RQ value for each one of them. mRNA expression of mCRPs was significantly reduced in AML and ALL patients in comparison with healthy controls. Data are expressed as means ± SD of three independent experiments for each sample done in duplicates and statistical one-way analysis of variance (ANOVA) was used to estimate the significance of difference between the different groups. P<0.001(***).
Techniques Used: Expressing, Quantitative RT-PCR, Comparison
Figure Legend Snippet: The expression level of CD55 in males and females showed a slight reduction in female AML patients compared to males, while the opposite was observed in ALL patients. Data are expressed as means ± SD of three independent experiments for each sample done in duplicates and statistical one-way analysis of variance (ANOVA) was used to estimate the significance of difference between the different groups.
Techniques Used: Expressing
Figure Legend Snippet: Flow cytometric analysis performed to measure the expression level of CD46 and CD55 in AML and ALL patients showed a significant reduction in CD46 expression in both types of acute leukemia patients. However, for CD55 a significant reduction was observed in AML patients only, while there was no significant difference observed in case of ALL patients. The expression level was calculated with reference to healthy controls. Data are represented as mean values ±SD for each sample done in duplicates, p<0.05 (*).
Techniques Used: Expressing
Figure Legend Snippet: Flow cytometric analysis of the protein expression level of both CD46 and CD55 in the peripheral blood samples of acute leukemia patients showed a significant reduction in both proteins compared to healthy controls. Results shown are from a representative experiment. (A) CD46 expression in a healthy control. (B) CD46 expression in an AML patient. (C) CD46 expression in an ALL patient. (D) CD55 expression in a healthy control. (E) CD55 expression in an AML patient. (F) CD55 expression in an ALL patient.
Techniques Used: Expressing, Control
Figure Legend Snippet: Knockdown of CD46 and CD55 protein expression in transfected cells was performed using shRNA silencing plasmids, each consisting of a pool of three different shRNA plasmids and PEI was used as the transfection reagent. Silencing of CD46 and CD55 proteins was done separately in addition to co-silencing of both proteins. Flow cytometric analysis was performed to measure the expression level of both proteins post transfection. Results showed a highly significant reduction in the expression level of both proteins. The percentage of inhibition was calculated relative to nonsilencing shRNA controls (=100%) p<0.001(***).

Techniques Used: Knockdown, Expressing, Transfection, shRNA, Inhibition
Figure Legend Snippet: Co-silencing of CD46 and CD55 expression in transfected cells led to a highly significant reduction in the expression of both proteins(p<0.001). A significant difference was observed between CD46 and CD55 knockdown(p<0.05).The percentage of inhibition was calculated relative to nonsilencing shRNA controls (=100%). p<0.001(***), p<0.05(*). (B) Flow cytometry analysis chart for CD46 and CD55 expression on HSB-2 cells transfected with combined CD46 and CD55 shRNA silencing plasmids. Dots in the third quadrant show the double negative expression for both CD46 and CD55 after knockdown of both CD46 and CD55 genes using combined CD46 and CD55 silencing shRNA plasmids.
Techniques Used: Expressing, Transfection, Knockdown, Inhibition, shRNA, Flow Cytometry
Figure Legend Snippet: Viability of HSB-2 cells was analyzed after silencing of CD46 and CD55 protein expression separately as well as combined silencing of both proteins using shRNA plasmids. Cell viability was assessed using MTT reagent in the presence of NHS as a source of complement. Cells had a reduced viability in the absence of CD46 (p<0.001) and CD55 (p<0.01) as well as in CD46 and CD55 co-silenced cells (p<0.01). P<0.01 (**), p<0.001 (***).
Techniques Used: Expressing, shRNA
