Fig. 7From: The midgut transcriptome of Aedes aegypti fed with saline or protein meals containing chikungunya virus reveals genes potentially involved in viral midgut escapeEffects of SM feeding on midgut collagen IV abundance and generic MMP activity. a Western blot showing abundance of midgut collagen IV at different time points post-SM feeding using polyclonal antibodies generated against human collagen IV. β-actin was detected as a loading control. Molecular masses in kDa are indicated. b Generic MMP activity of midgut lysates prepared from mosquitoes that had received a BM, PM, or SM at 1 and 2 dpf (sugar, control). Mean values with standard deviations (SD) from three independent experiments are shown. Different letters indicate significant differences based on one-way analysis of variance (ANOVA) followed by Tukey's multiple comparisons test (* at p ≤ 0.01). BM, blood meal (from sheep); SM, saline meal (PBS); PM, protein meal (BSA)Back to article page
