Propofol Affects Non-Small-Cell Lung Cancer CellBiology By Regulating the miR-21/PTEN/AKT Pathway In Vitro and In Vivo
Background: Propofol is a common sedative-hypnotic drug traditionally used for inducing and maintaining general anesthesia. Recent studies have drawn attention to the nonanesthetic effects of propofol, but the potential mechanism by which propofolsuppresses non-small-cell lung cancer (NSCLC) progression has not been fully elucidated.
Methods: For the in vitro experiments, we used propofol (0, 2, 5, and 10 µg/mL) to treat A549 cells for 1, 4, and 12 hours and Cell Counting Kit-8 (CCK-8) to detect proliferation. Apoptosis was measured with flow cytometry. We also transfected A549 cells with an microribonucleic acid-21 (miR-21) mimic or negative control ribonucleic acid (RNA) duplex and phosphatase and tensin homolog, deleted on chromosome 10 (PTEN)
small interfering ribonucleic acid (siRNA) or negative control. PTEN, phosphorylated protein kinase B (pAKT), and protein kinase B (AKT) expression were detected using Western blotting, whereas miR-21 expression was examined by real-time polymerase chain reaction (RT-PCR). In vivo, nude mice were given injections of A549 cells to grow xenograft tumors; 8 days later, the mice were intraperitoneally injected with propofol (35 mg/kg) or soybean oil. Tumors were then collected from mice and analyzed by immunohistochemistry and Western blotting.
Results: Propofol inhibited growth (1 hour, P = .001; 4 hours, P ≤ .0001; 12 hours, P = .0004) and miR-21 expression (P ≤ .0001) and induced apoptosis (1 hour, P = .0022; 4 hours, P = .0005; 12 hours, P ≤ .0001) in A549 cells in a time and concentration-dependent manner. MiR-21 mimic and PTEN siRNA transfection antagonized the suppressive effects of propofol on A549 cells by decreasing PTEN protein
expression (mean differences [MD] [95% confidence interval {CI}], -0.51 [-0.86 to 0.16], P = .0058; MD [95% CI], 0.81 [0.07-1.55], P = .0349, respectively), resulting in an increase in pAKT levels (MD [95% CI] = -0.82 [-1.46 to -0.18], P = .0133) following propofol exposure. In vivo, propofol treatment reduced NSCLC tumor growth (MD [95% CI] = -109.47 [-167.03 to -51.91], P ≤ .0001) and promoted apoptosis (MD [95% CI] = 38.53 [11.69-65.36], P = .0093).
Conclusions: Our study indicated that propofol inhibited A549 cell growth, accelerated apoptosis via the miR-21/PTEN/AKT pathway in vitro, suppressed NSCLC tumor cell growth, and promoted apoptosis in vivo. Our findings provide new implications for propofol in cancer therapy and indicate that propofol is extremely advantageous in surgical treatment.

Self-Organizing Human Induced Pluripotent Stem Cell Hepatocyte 3D Organoids Inform the Biology of the Pleiotropic TRIB1 Gene
Establishment of a physiologically relevant human hepatocyte-like cell system for in vitro translational research has been hampered by the limited availability of cell models that accurately reflect human biology and the pathophysiology of human disease. Here we report a robust, reproducible, and scalable protocol for the generation of hepatic organoids from human induced pluripotent stem cells (hiPSCs) using short exposure to nonengineered matrices.
These hepatic organoids follow defined stages of hepatic development and express higher levels of early (hepatocyte nuclear factor 4A [HNF4A], prospero-related homeobox 1 [PROX1]) and mature hepatic and metabolic markers (albumin, asialoglycoprotein receptor 1 [ASGR1], CCAAT/enhancer binding protein α [C/EBPα]) than two-dimensional (2D) hepatocyte-like cells (HLCs) at day 20 of differentiation. We used this model to explore the biology of the pleiotropic TRIB1 (Tribbles-1) gene associated with a number of metabolic traits, including nonalcoholic fatty liver disease and plasma lipids.
We used genome editing to delete the TRIB1 gene in hiPSCs and compared TRIB1-deleted iPSC-HLCs to isogenic iPSC-HLCs under both 2D culture and three-dimensional (3D) organoid conditions. Under conventional 2D culture conditions, TRIB1-deficient HLCs showed maturation defects, with decreased expression of late-stage hepatic and lipogenesis markers.
In contrast, when cultured as 3D hepatic organoids, the differentiation defects were rescued, and a clear lipid-related phenotype was noted in the TRIB1-deficient induced pluripotent stem cell HLCs. Conclusion: This work supports the potential of genome-edited hiPSC-derived hepatic 3D organoids in exploring human hepatocyte biology, including the functional interrogation of genes identified through human genetic investigation.

Description: Conventional cells used for retrovirus packaging, such as those based on NIH3T3 cells, have limited stability and produce relatively low yields of retrovirus, mainly due to the poor expression of retroviral structure proteins (gag, pol and env) in the cells. The Platinum Retroviral Packaging Cell Lines are based on the 293T cell line. They exhibit longer stability and produce higher yields of retroviral structure proteins. Plat-E cells contain gag, pol and env genes, allowing retroviral packaging with a single plasmid transfection.

Plat-GP cells contain the gag and pol genes required for retroviral packaging; an expression vector is co-transfected with a VSVG envelope vector.
Green Fluorescent Protein (GFP-fusion protein) ELISA Kit, 96 tests, Quantitative
Description: Cell Biolabs? GFP Quantitation Kit measures GFP fluorescence in a fluorometer. The quantity of rGFP in sample is determined by comparing its fluorescence reading with that of known recombinant GFP standard curve. The kit has detection sensitivity limit of 100 ng/mL. A proprietary GFP quench solution is also included for determining autofluorescence of cell or tissue sample. Each kit provides sufficient reagents to perform up to 100 assays including standard curve and GFP samples.
Description: Most imaging studies of rGFP are qualitative, and quantitation by FACS is time-consuming and expensive. Our GFP ELISA Kit measures green fluorescent protein in a standard microplate reader. Assay is sensitive to 30 pg/mL.
