MicroRNAs as regulators of VEGFA and NFE2L2 in cancer.
llo E Abstract MicroRNAs (miRNAs) are small non-coding RNAs that are involved in post-transcriptional regulation of various genes, and their deregulation can lead to tumorigenesis. They may play the role of oncogenes or tumor suppressors by regulating different genes involved in cellular processes. One of the genes regulated by the miRNAs is the vascular endothelial growth factor A (VEGFA), which is responsible for angiogenesis. Angiogenesis is the process of formation of new blood vessels from pre-existing ones. This process plays an important role in tumor development, since it is responsible for the transport o...

Role of microRNAs in the development, prognosis and therapeutic response of patients with prostate cancer.
Abstract Prostate cancer is the most common cancer in males in several regions. One of the major challenges in diagnosis and treatment of this cancer is how to identify men who harbor an increased risk of having clinically significant prostate cancer and how to assess response to therapy. Biomarkers, like microRNAs (miRNAs) are one of the new diagnostic/therapeutic tools for clinicians. Finding men at high risk of significant cancer is essential as they will mostly benefit from earlier diagnosis and treatment. At the same time, it is important to reduce the number of unnecessary invasive biopsies in men without (c...

Polymorphisms of CSF1R and WISP1 genes are associated with severity of familial adenomatous polyposis in APC1311 pigs.
Abstract Hereditary familial adenomatous polyposis (FAP) in humans significantly increases the risk of development of colorectal cancer (CRC). Germline mutations in the APC (adenomatous polyposis coli) gene are responsible for FAP. Despite having the same causative mutation, the severity of the disease differs from patient to patient. The porcine FAP model carrying a truncating APC1311 mutation, orthologous to the dominant human mutation that leads to severe form of the disease (APC1309), mirrors the severity of polyposis. Earlier RNAseq studies have revealed the differential expression of WISP1 and CSF1R in sampl...

In this study, the GbTCP5 gene encodes a sea-island cotton class II TCP CIN subclass transcription factor. The GbTCP5 transcription factor is located in the nucleus, has transcriptional activation activity, and can bind to TCP II cis-acting elements. GbTCP5 was widely expressed in tissues with the highest transcript level in the calyx. GbTCP5 is expressed at different developmental stages of the fiber and has significantly high transcriptional level expression in the fibers at 20, 30 and 35 days post anthesis (DPA). Heterologous overexpression of the GbTCP5 gene increased root hair length, root hair and stem trichome densi...

Detection of polymorphisms in the bovine leptin receptor gene affects fat deposition in two Chinese beef cattle breeds.
This study investigated the presence and frequency of polymorphisms of bovine LEPR gene and determine whether the polymorphisms are associated with the fat deposition in two Chinese beef cattle breeds. Quantitative real-time polymerase chain reactions identified that the expression of LEPR gene was highest in the liver and subcutaneous fat. Four single nucleotide polymorphisms (SNPs) were identified including g.24169 C>T, g.24256 T>A, g.24267 G>C and g.24413 T>A. A greater backfat thickness was associated with the AA genotype of g.24256 T>A compared to the TT genotype. A greater intramuscular fat content was...

Emerging roles of melanocortin receptor accessory proteins (MRAP and MRAP2) in physiology and pathophysiology.
Abstract In summary, genetic variants of MRAP are associated with severe familial glucocorticoid deficiency, however evidence is emerging that synthetic glucocorticoids may also disrupt ACTH and MRAP expression resulting in adrenal inflammation. MRAP2 genetic variants are associated with severe obesity but the phenotypes are subtly different to the phenotypes observed with MC4R genetic variants. There is a great deal of interest in the development of melanocortin therapeutics to treat obesity, as evidenced by setmelanotide, and fully understanding the role of MRAP2 and the interactions with both melanocortin recep...

FoxM1 promotes the migration of ovarian cancer cell through KRT5 and KRT7.
Abstract Forkhead box M1(FoxM1) played an important role in the pathogenesis of ovarian cancer, but its downstream molecular network is mysterious. Here, we combined ChIP-seq with RNA-seq analysis and identified 687 FoxM1-binding regions and 182 genes regulated by FoxM1. The above data pointed out that KRT5 and KRT7 were downstream target genes of FoxM1. Next, we used qPCR and Western blot to verify that FoxM1 knockdown inhibited the expression levels of KRT5 and KRT7. We also demonstrated that FoxM1 regulated KRT5 and KRT7 genes expression through binding a consensus AP-2 cis element, and showed that KRT5 and KRT...

VcMYB4a, an R2R3-MYB transcription factor from Vaccinium corymbosum, negatively regulates salt, drought, and temperature stress.
In this study, we cloned a novel MYB TF gene from Vaccinium corymbosum (blueberry) using rapid amplification of cDNA ends (RACE). The cDNA contained a 798-bp open reading frame that encodes a 265-amino acid protein. VcMYB4a possessed a C2/EAR-repressor motif domain and phylogenetic analysis showed that it clustered into a subgroup 4 with six Arabidopsis thaliana MYBs. Quantitative RT-PCR analysis demonstrated that VcMYB4a expression was downregulated by salt, drought, and cold treatment, but was induced by freezing and heat. Overexpression of VcMYB4a in blueberry callus enhanced sensitivity to salt, drought, cold, freezing...

Overexpression of the Tuberous sclerosis complex 2 (TSC2) gene inhibits goat myoblasts proliferation and differentiation in understanding the underlying mechanism of muscle development.
Abstract The growth of animal skeletal muscle is mainly determined by the synthesis processes of total proteins in skeletal muscle cells, which has a significant impact on the postnatal growth of young animals. An increasing number of studies are focusing on the functions of Tuberous sclerosis complex 2 (TSC2) during the process of cell protein synthesis and growth. However, it is still unclear the effect of whether and how TSC2 on goat myoblasts proliferation and differentiation. Here, we found that TSC2 gene has opposite expression patterns in proliferation and differentiation of myoblasts. An expression vector ...

Implication of Pseudo Reference Genes in Normalization of Data from Reverse Transcription-Quantitative PCR.
Abstract Pseudogenes are duplicated or retrotransposed DNA sequences of native functional genes. Amplification of pseudogenes along with gene of interest often produces false positive results, which is an innate problem in Reverse Transcription-quantitative PCR (RT-qPCR). Selecting a reference gene without any interference from pseudogene amplification is therefore a challenge to overcome. Among the common reference genes used for normalization (ACTB, GAPDH, HPRT1, TUBB, 18SrRNA and B2M), B2M was found to have no pseudogenes in silico, which has also been confirmed by RT-qPCR. We also assessed the effect of pseudo...
