Figure Lengend Snippet: Improving the tolerance to formaldehyde via ALE. (A) Growth of FM-1 in minimal medium with 10 g/L glucose and different formaldehyde concentrations. 0 mM (square), 0.5 mM (triangle), 0.8 mM (circle), and 1 mM (inverted triangle). (B) ALE procedure of culture-1 in CGXII minimal medium supplemented with different formaldehyde concentrations and 10 g/L glucose. (C) Growth curve of the evolved mutants in CGXII minimal medium supplemented with 10 g/L glucose and 0.8 mM formaldehyde. (D) Growth curve of evolved mutant in CGXII minimal medium supplemented with 10 g/L glucose and 1.6 mM formaldehyde. (E) Growth curve of evolved mutant in CGXII minimal medium supplemented with 10 g/L glucose. (F) Formaldehyde degradation during cell growth of wild-type C. glutamicum ATCC 13032, FM-1 and FM-3. Values and error bars reflect the mean ± s.d. of three biological replicates (N = 3).

Article Snippet: The mutant cgl1590 fragment was amplified from the genomic DNA of C. glutamicum ATCC 13032 using the primer pairs cgl1590 750insG -F1/ cgl1590 750insG - R1, cgl1590 750insG -F2/ cgl1590 750insG -R2, and then ligated with the Bam HI-linearized pK18 mobsacB using the ClonExpress MultiS One Step Cloning Kit (Vazyme Biotech, China).

Article Title: Influence of diet-induced obesity and voluntary exercise training on cardiac lipids and mitochondrial function in mice

doi: 10.1016/j.jshs.2025.101095

Figure Lengend Snippet: Voluntary exercise alters left ventricle gene and protein expression related to mitochondrial biogenesis and dynamics in high fat- and chow-fed mice. (A) Western blot analysis to assess purity of crude mitochondria isolation where left ventricle mitochondrial pellet expresses mitochondrial marker TOM70 and COXIV and supernatant expresses calnexin. Protein expression of (B) LCLAT1 and (C) MFN2 in left ventricle-isolated crude mitochondria and (D) LCLAT1, (E) PGC-1α, and (F) MFN2 in left ventricle tissue from male VET or sedentary mice fed an HFD or chow diet. Left ventricle mRNA expression of (G) OPA1 and (H) DRP1 in male VET or sedentary mice fed an HFD or chow diet. Values were calculated relative to 18S housekeeper. Calnexin and β-actin were used as internal controls of protein loading in left ventricle samples and COXIV as internal control of protein loading in crude mitochondria samples. Analysis was performed using two-way analysis of variance with Tukey’s post hoc test for multiple comparisons. Data are expressed as mean ± standard error of the mean. (B–C) n : 5–6 per group. (D–F) n = 7 per group. (G and H) n = 9 per group. CE = chow exercise; CS = chow sedentary; COXIV = cytochrome c oxidase subunit 4; DRP1 = dynamin-related protein 1; HE = high fat diet exercise; HFD = high fat diet; HS = high fat diet sedentary; LCLAT1 = lysocardiolipin acyltransferase 1; MFN2 = mitofusin-2; OPA1 = optic atrophy 1; PGC-1α = peroxisome proliferator-activated receptor gamma coactivator-1α; TOM70 = translocase of outer mitochondria membrane 70; VET = voluntary exercise training.

Article Snippet: The plate was centrifuged at 500 g for 5 min at 4°C, and 140 μL of MAS buffer containing 10 μg/mL cytochrome C (Thermo Fisher Scientific) was pipetted to each well.

Article Snippet: Each evolved strain possesses more than 100 mutations including single nucleotide polymorphisms (SNPs), insertions, and deletions, which were aligned against the C. glutamicum ATCC 13032 reference genome (GenBank accession number GCA_000011325.1).
