Article Snippet: In vitro studies , • Few chemoprevention studies conducted • Antioxidants with chemopreventive effects against Cr(III) cyto/genotoxicity: ○ Tempol in human lymphocytes: inhibits cyto/genotoxicity ○ Zinc in PBL: inhibits apoptosis, reduces ROS production, reverses changes in mitochondrial membrane potential, ATP levels, activation of caspase 3 , • Antioxidants with chemopreventive effects against Cr(VI) cyto/genotoxicity: ○ Apple juice in A549: scavenges hydroxyl radicals, reduces lipid peroxidation, DNA damage, cell apoptosis, NFκB activation ○ Quercetin in BEAS2B: decreases ROS generation, inhibits cell transformation, increases miR21 expression, and inhibits of PDCD4 ○ Luteolin in BEAS2B: scavenges ROS ○ EDE in AMJ2-C11: protects against cytotoxicity and oxidative stress ○ Tempol in human lymphocytes: inhibits cyto- and genotoxicity ○ NAC in L02 hepatocytes, H460, HaCaT: inhibits suppression of apoptosis, p53 activation, HSP72 and HIF1α upregulation, prevents ROS-mediated cell death and cytokine expression, decreases rate of cell apoptosis, alleviates mitochondrial and DNA damage – ○ Vitamin C: inhibits increase in DPCs, complete protection against cytotoxicity ○ Lawsonia inermis extract in MDA-MB-435S: scavenges free radicals, inhibits lipid peroxidation ○ Phyllanthus amarus aqueous extract in MDA-MB-435S: inhibits Cr(VI)-induced oxidative toxicity ○ EGCG in BEAS2B: scavenges ROS, protects against DNA damage, inhibits activation of NFκB 7 ○ Melatonin in rat hepatocytes: protects against DSBs, cytotoxicity, lipid peroxidation ○ MCE in BEAS2B, PBL: increases cell viability, decreases DNA damage and ROS level .

Article Title: Aptamin C enhances anti-cancer activity NK cells through the activation of STAT3: a comparative study with vitamin C

doi: 10.5115/acb.24.120

Figure Lengend Snippet: Comparison of vitamin C levels in the tissues of Gulo knockout (KO) mice treated with vitamin C and Aptamin C. Vitamin C levels were measured in the stomach, spleen, brain, liver, lung, and adrenal gland of Gulo KO mice (n=5) supplemented with vitamin C (3.3 g/L) and Aptamin C (vitamin C 3.3 g/L, aptamer 33 mg/L) for 2 and 4 weeks. Vitamin C level was measured by using a colorimetric microtiter plate assay kit as described in Materials and Methods. Data were analyzed by one-way ANOVA with Tukey’s multiple comparison test and presented as the mean±SD. Three independent experiments were performed. ns, not significant; WT, wild type. * P <0.05, ** P <0.01, *** P <0.001.

Article Snippet: The homogenates were centrifuged at 14,000 rpm for 30 minutes at 4°C, and the supernatants were used for measuring vitamin C. The tissue homogenates were diluted in PBS, and vitamin C (ascorbic acid) was converted into its oxidized form, dehydroascorbic acid (DHA), after which the total DHA concentration was measured using a colorimetric microtiter plate assay kit (Immundiagnostik AG) according to the manufacturer’s instructions.
