Figure Lengend Snippet: TGC and/or unloaded CD NPs ameliorated the S. Typhimurium infected group induced histopathological alterations in mice’s liver tissues. Representative photomicrographs of the H&E-stained hepatic tissue sections showing the control (A), S. Typhimurium infected group (C), TGC (E), unloaded CD NPs (G), CD-TGC groups (I) and their respective higher magnifications (B, D, F, H, and J). A, B: control group displaying normal central vein (CV), hepatic cords (HC) with hepatocytes of eosinophilic granular cytoplasm (EC), rounded central single (SN) or double vesicular nuclei (DN), and kupffer cells (KC). C, D: S. Typhimurium infected group demonstrating multiple areas of variable-sized necrotic areas (NA) of coagulative necrosis (CN), severely dilated and congested sinusoid (SDS) with Kupffer cell hyperplasia (KCH). E, F: TGC group displaying moderately sized necrotic areas (MNA), moderately dilated and congested sinusoids (MDS), moderately hyperplastic Kupffer’s cells (MKC), interstitial mononuclear cell infiltration (MI), fibroblast proliferation (FP), and regenerated hepatocytes of stippling basophilic cytoplasm (BC) and pale nuclei (PN). G, H: unloaded CD NPs group showing a few scattered minute necrotic areas (mNA), intense mononuclear cell infiltration (IMI) around the portal area, and apparently normal hepatocytes (NH). I, J: CD-TGC group showed normal hepatocytes (NH), few dilated blood vessels (DBV), and a few interstitial lymphocytic aggregates (FL). Scale bars = 100 μm in A, C, E, G, I; and = 20 μm in B, D, F, H, and J. K: Bar charts demonstrate the statistical analysis of the comparative quantification of the hepatic injury scores in all studied groups. Bars carrying different superscript letters (a, b, c, d, and e) are significantly different as analyzed by the one-way ANOVA test, followed by the multiple comparisons by Duncan’s Post-hoc test ( p < 0.05). Values are the mean of 6 mice per group ± S.E.M.

Figure Lengend Snippet: BJ-5ta cells were transfected with either a non-specific control siRNA (siC) or an eIF5B-specific siRNA pool (si-eIF5B). (A) Following 24 h of transfection, cells were treated with either vehicle control or TRAIL (100 ng/mL). Cell viability was assessed after an additional 72 h using alamarBlue TM assays. (B) Annexin V and 7-AAD staining and flow cytometric analysis of transfected cells. The top two panels, siC and siC + TRAIL, the bottom two panels, si5B and si5B + TRAIL, were harvested at 96 h post-transfection and treated with Annexin V + 7AAD. Contour plots are divided into quadrants Live (lower left; cells staining negative for both 7-AAD and annexin V), Q1 (upper left; cells staining positive for 7-AAD but negative for annexin V), Early apoptosis (lower right; staining annexin V positive and 7-AAD negative), and Late apoptosis (upper right; staining positive for both 7-AAD and annexin V). (C) Representative immunoblots probing for eIF5B, XIAP, Bcl-xL, cIAP1, cFLIPs, DR 4, DR 5, and β-actin (internal control) are shown. ( D) Control and eIF5B-depleted BJ-5ta cells were treated with the 4EGI-1 inhibitor to inhibit cap-dependent translation. Levels of XIAP were monitored under control and the 4EGI-1 treatment conditions. (E) eIF5B-bound RNA immunoprecipitations (RIPs) followed by qRT-PCR measurements of input-normalized tRNAiMet levels from BJ-5ta vs UMSCC-29. Data are presented as mean ± SEM from three independent biological replicates, with statistical significance indicated as follows: *, p < 0.05; **, p < 0.01; ***, p < 0.001.

Figure Lengend Snippet: BJ-5ta cells were transfected with either control siRNA (siC) or eIF5B-specific siRNA (si5B) and incubated for 96 hours. TRAIL (100 ng/mL) treatment was performed for 4 hours, then the media was collected.
