05). Haplotype analysis results indicated that Trs11168100Ars353303Trs353300Crs353299 acts as a protective factor of esophageal cancer with OR of 0.71 (95% CI = 0.52-0.98, p = 0.038), while Ars11168100Grs353303Crs353300 and Ars11168100Ars353303 have 1.49-fold (OR = 1.49, 95% CI = 1.02-2.19, p = 0.041) and 1.57-fold (OR = 1.57, 95% CI = 1.05-2.35, p = 0.027) increased risk of esophageal cancer, respectively. CONCLUSION The results of our study suggested that CARMN variations may affect the risk of esophageal cancer. OBJECTIVE lacZ encodes for β-galactosidase within the galactose operon of bacterial cells. When used as a reporter gene, bacterial "β-galactosidase" expression is often insufficient for detection in mammalian cells. We intended to optimize the lacZ codon usage according to the most frequently used codons for the seven major proteins in cow's milk, in order to pave a way for the enhancement of transgenic genes expression in eukaryotes. RESULTS We constructed modified lacZ (named olacZ) according to optional codons used for proteins expressed in cow's milk. The expression of lacZ and olacZ was then compared in HC11 (a murine mammary gland epithelial line), 293T, HeLa, Cos7, and NIH 3T3 cells. While there was no significant difference at the mRNA level between lacZ and olacZ (P > 0.05). The quantification of β-galactosidase activity and in situ staining experiments showed a 1.2-fold to 3.3-fold expression improvement when comparing olacZ with lacZ. The levels of β-galactosidase expression at the protein levels from olacZ were approximately 9.2-fold and 2.4-fold respectively for Cos7 and HC11 cells. Furthermore, a 1.9-fold tendency of enhanced expression of olacZ in mammary gland during lactation was observed in transgenic-olacZ mice. CONCLUSION This study demonstrates an alternative choice for improving lacZ reporter expression in eukaryotes, especially in the mammary gland of cattle or goats. Brain and muscle Arnt-like protein-1 (BMAL1) is a clock gene that plays an important role in hormone secretion and apoptosis, but its effect on Leydig cells is unidentified. Here the role of BMAL1 in apoptosis and testosterone secretion in TM3 Leydig cell line were investigated by inhibiting its expression using small interfering RNA (siRNA). Results showed that BMAL1 knockdown promoted the apoptosis of Leydig cells and expression of (BCL2 associated X) BAX mRNA and protein, and reduced the expression of (B-cell lymphoma-2) BCL-2 mRNA and protein. BMAL1 inhibition resulted in decreased testosterone secretion and reduced expression of key genes during hormone synthesis, specifically steroidogenic acute regulatory protein (STAR), cytochrome P450 family 11 subfamily A member 1 (CYP11A1), and 3β-hydroxysteroid dehydrogenase (3β-HSD). In addition, BMAL1 knockdown reduced the expression of phosphorylated p85 and AKT as confirmed by western blot. Veliparib In conclusion, BMAL1 may affect testosterone secretion and apoptosis in mouse Leydig cells through regulation of the PI3K/AKT signaling pathway. V.Previous reports have revealed that circRNA_100876 was extremely important in the progression of triple-negative breast cancer. Nevertheless, the mechanism towards the role of circRNA_100876 in Gastric cancer (GC) remains unknown. Here, we determined circRNA_100876 expression by quantitative real-time PCR (qRT-PCR) in twenty pairs of GC tissues and adjacent tissues. Our data indicated that the expression of circRNA_100876 was raised in GC tissues. In vitro, functional experiments confirmed that cell proliferation, invasion along with migration was promoted by circRNA_100876 in GC tissues. Simultaneously, relative luciferase assay uncovered that circRNA_100876 functioned as a sponge for miR-136, followed by retarding miR-136-induced inhibited effects on the corresponding target, MIEN1. Moreover, we revealed that the expression of MIEN1 was up-regulated and correlated to much worse prognosis of GC. Collectively, our data identified that the promotion of GC growth and metastasis induced by circRNA_100876 interacted with miR-136 and MIEN1, indicating an emerging announcement for uncovering the potential mechanism of GC progression. Feruloyl esterases synthesize butyl hydroxycinnamates, molecules possessing interesting biological properties, nonetheless, they exhibit a low stability under synthesis conditions in organic solvents, restricting its use. To enhance its operational stability in synthesis, we immobilized type A feruloyl esterase from Aspergillus niger (AnFAEA) using several carrier-bound and carrier-free strategies. The most active biocatalysts were 1) AnFAEA immobilized on epoxy-activated carriers (protein load of 0.6 mgenzyme x mg-1carrier) that recovered 91 % of the initial hydrolytic activity, and 2) AnFAEA aggregated and cross-linked in the presence of 5 mg of BSA and 15 mM of glutaraldehyde (AnFAEA-amino-CLEAs), which exhibited 385 % of its initial hydrolytic activity; both using 4-nitrophenyl butyrate as substrate. The AnFAEA-amino-CLEAs were 12.7 times more thermostable at 60 °C than the AnFAEA immobilized on epoxy-activated carrier, thus AnFAEA-amino-CLEAs were selected for further characterization. Interestingly, during methyl sinapate hydrolysis (pH 7.2 and 30 °C), AnFAEA-amino-CLEAs KM was 15 % higher, while during butyl sinapate synthesis the KM was reduced in 63 %, both compared with the soluble enzyme. The direct esterification of butyl sinapate at solvent free conditions using sinapic acid 50 mM, reached 95 % conversion after 24 h employing AnFAEA-amino-CLEAs, which could be used for 10 cycles without significant activity losses, demonstrating their outstanding operational stability. Wheat (T. aestivum L.) is the second most important staple food crop consumed in the form of various end-use products across the world. However, it contains lower concentrations of Fe and Zn leading to micronutrient deficiency in human beings where wheat is the sole diet. Therefore, increasing grain Fe/Zn content in wheat has become priority in wheat breeding programmes across the world. Understanding the molecular mechanism of Fe/Zn transport and accumulation in grains is required to expedite the breeding process. For this purpose, whole seedling transcriptome analysis was conducted in four wheat genotypes (CRP 1660, Sonora 64, Vinata, high, and DBW17 low) differing in grain Fe/Zn content under controlled and Fe/Zn deficient conditions. Twenty eight key transcripts involved in phytosiderophore biosynthesis, Fe/Zn uptake and transport were identified. Expression analysis of 12 of the transcripts using qPCR was conducted in seedling stage and flag leaf which exhibited greater differential accumulation in CRP 1660 followed by Vinata, Sonora 64 and DBW 17 in both flag leaf and seedling.
