Genome-wide identification of internal reference genes for normalization of gene expression values during endosperm development in wheat.
Abstract Internal reference genes that are stably expressed are essential for normalization in comparative expression analyses. However, gene expression varies significantly among species, organisms, tissues, developmental stages, stresses, and treatments. Therefore, identification of stably expressed reference genes in developmental endosperm of bread wheat is important for expression analysis of endosperm genes. As the first study to systematically screen for reference genes across different developmental stages of wheat endosperm, nine genes were selected from among 76 relatively stable genes based on high-thro...

Relevance of solute carrier family 5 transporter defects to inherited and acquired human disease.
De Paepe B Abstract The solute carrier (SLC) group of membrane transport proteins is crucial for cells via their control of import and export of vital molecules across the cellular membrane. Defects in these transporters with narrow substrate specificities cause monogenic disorders, giving us essential clues of their precise roles in cellular functioning. The SLC5 family in particular has been linked to various human diseases, of mild and severe phenotype as well as high and low prevalence. In this review, we describe the effects on health of SLC5 dysfunction and dysregulation by summarizing findings in patients ...

Efflux pumps as an additional source of resistance to trichothecenes in Fusarium proliferatum and Fusarium oxysporum isolates.
Abstract Role of efflux-mediated toxin resistance to trichothecenes is known in trichothecene-producing species. However, the role of trichothecene efflux pump homologues in non-producing fusaria such as F. oxysporum and F. proliferatum was not investigated in detail. Analysis of the homologues of trichothecene efflux pump from multiple fungal species allowed us to uncover and catalogue functional gene copies of conserved structure. Putative Tri12 candidates in Fusarium oxysporum and F. proliferatum were characterised via expression profiling in response to different trigger compounds, providing supporting evidenc...

MicroRNA transcriptome analysis of poly I:C-stimulated and PRRSV-infected porcine alveolar macrophages.
Abstract Porcine reproductive and respiratory syndrome virus (PRRSV) causes severe reproductive failure in sows, respiratory diseases, and high mortality in piglets, which results in serious economic losses to the swine industry worldwide. Previous studies have described that PRRSV could suppress the host immune system and had antiapoptotic activity in its initial phase of infection. Polyinosinic-polycytidylic acid (poly I:C), a synthesized analogue of viral double-strand RNA, activates innate immunity responses and induces apoptosis in cells. Therefore, we performed miRNA transcriptome analysis of poly I:C-stimul...

Novel data on growth phenotype and causative genotypes in 29 patients with Morquio (Morquio-Brailsford) syndrome from Central-Eastern Europe.
ska A Abstract Mucopolysaccharidosis type IVA, also known as Morquio (Morquio-Brailsford) syndrome results from accumulation of keratan sulfate (KS) and chondroitin-6-sulfate (C6S), whereas the primary cause is mutations in the gene encoding galactosamine (N-acetyl)-6-sulfatase (GALNS). Phenotypically it seems to be a well-defined condition, with two main clinical forms: mild (attenuated) and severe, which are determined based on a combination of symptoms, i.e., enzymatic activity of GALNS, age of onset, and symptom severity. Nevertheless, the natural history of MPSIVA in relation to specific anthropometric parame...

Do GWAS and studies of heterozygotes for NPC1 and/or NPC2 explain why NPC disease cases are so rare?
Abstract Early onset Niemann-Pick C diseases are extremely rare, especially Niemann-Pick C2. Perhaps unusually for autosomal recessive diseases, heterozygotes for mutations in NPC1 manifest many biological variations. NPC2 deficiency has large effects on fertility. These features of NPC1 and NPC2 are reviewed in regard to possible negative selection for heterozygotes carrying null and hypomorphic alleles.

Myofibrillar myopathy in the genomic context.
Abstract Myofibrillar myopathy (MFM) is a group of inherited muscular disorders characterized by myofibril dissolution and abnormal accumulation of degradation products. The diagnosis of muscular disorders based on clinical presentation is difficult due to phenotypic heterogeneity and overlapping symptoms. In addition, precise diagnosis does not always explain the disease etiopathology or the highly variable clinical course even among patients diagnosed with the same type of myopathy. The advent of high-throughput next-generation sequencing (NGS) has provided a successful and cost-effective strategy for identifica...

The influence of Al3+ on DNA methylation and sequence changes in the triticale ( × Triticosecale Wittmack) genome.
In this study, liquid chromatography (RP-HPLC), methylation amplified fragment length polymorphisms (metAFLP), and methylation-sensitive amplification polymorphisms (MSAP) analysis was used to investigate the effects of aluminum (Al) stress on DNA methylation levels in the crop species triticale. RP-HPLC, but not metAFLP or MSAP, revealed significant differences in methylation between Al-tolerant (T) and non-tolerant (NT) triticale lines. The direction of methylation change was dependent on phenotype and organ. Al treatment increased the level of global DNA methylation in roots of T lines by approximately 0.6%, whereas dem...

Elevated expression of p53 in early colon polyps in a pig model of human familial adenomatous polyposis.
Abstract Familial adenomatous polyposis (FAP) is a hereditary predisposition to formation of colon polyps that can progress to colorectal cancer (CRC). The severity of polyposis varies substantially within families bearing the same germline mutation in the adenomatous polyposis coli (APC) tumour suppressor gene. The progressive step-wise accumulation of genetic events in tumour suppressor genes and oncogenes leads to oncogenic transformation, with driver alterations in the tumour protein p53 (TP53) gene playing a key role in advanced stage CRC. We analysed groups of pigs carrying a truncating mutation in APC (APC1...

hTERT promoter methylation status in peripheral blood leukocytes as a molecular marker of head and neck cancer progression.
Abstract Cancer cells, including head and neck cancer cell carcinoma (HNSCC), are characterized by an increased telomerase activity. This enzymatic complex is active in approximately 80-90% of all malignancies, and is regulated by various factors, including methylation status of hTERT gene promoter. hTERT methylation pattern has been thoroughly studied so far. It was proved that hTERT is aberrantly methylated in tumor tissue versus healthy counterparts. However, such effect has not yet been investigated in PBLs (peripheral blood leukocytes) of cancer patients. The aim of this study was to analyze the hTERT gene pr...

Disease not genetic but infectious: multiple tuberculomas and fibrinous pericarditis as symptoms pathognomonic for tuberculosis of Frederic Chopin.
Abstract Chopin's heart, generally enlarged, presented morphologic features pathognomonic for fibrinous pericarditis presumably of tubercular origin: multiple nodular hyalinization foci-tuberculomas and fibrillary coating covering the whole surface of pericardium ("frosted heart"). We show that these features differ significantly from post mortem-formed inorganic crystalline deposits, mold colonies, or fat deposits known from various preserved anatomical objects stored for a long period of time. In our opinion, these pathologies fully justify the claim that chronic cavernous pulmonary, laryngeal, and int...

Identification and expression of genes in response to cassava bacterial blight infection.
In this study, quantitative trait loci (QTL) associated with CBB infection were identified in the F1 progenies of a cross between the "Huay Bong 60" and "Hanatee" cassava cultivars. The phenotype of disease severity was observed at 7, 10, and 12 days after inoculation (DAI). A total of 12 QTL were identified, of which 5, 6, and 1 were detected in 7, 10, and 12 DAI samples, respectively. Among all identified QTL, CBB14_10dai_1, CBB14_10dai_2, and CBB14_12dai showed the most significant (P

An EMS-induced new sequence variant, TEMS5032, in the coding region of SRS3 gene leads to shorter grain length in rice (Oryza sativa L.).
Abstract Grain shape and size influence yield and consumer preferences in rice. In the present study, we characterized and mapped a short and bold grained mutant and named it as TEMS5032, as the mutant is a result of EMS-induced transition from C to T at the 5032nd bp of SRS3 gene, which is known to affect grain size in rice. The substitution led to creation of a stop codon in the motor domain of SRS3, a kinesin 13 family gene, translating into a truncated protein product. However, transcription of this gene remained unaffected in TEMS5032 compared to the wild type, N22. Further, the mutation was found to affect 1...

Transcriptome analysis reveals candidate genes involved in splay leg syndrome in piglets.
Abstract Splay leg is frequently observed in newborn piglets and leads to economic loss as well as welfare concerns. However, the etiology and pathogenesis of splay leg syndrome in piglets are still poorly understood. The aims of this paper were to characterize changes in the transcriptome of splay leg piglets and identify candidate genes responsible for this disease. We chose three splay leg piglets and their healthy full sibs, and constructed six RNA libraries using skeletal muscle samples from both groups and identified the differentially expressed genes between the two groups using RNA-seq. A total of 555 diff...

Population analysis of Magnaporthe oryzae by using endogenous repetitive DNA sequences and mating-type alleles in different districts of Karnataka, India.
Abstract Rice is the staple food crop of more than 60% of the population of the world. This crop suffers from blast disease caused by Magnaporthe oryzae. Information on the mating-type allele distribution and diversity of the pathogen population for the state of Karnataka, India is scanty. With this background, a total of 72 isolates of M. oryzae from rice in different districts of Karnataka were examined for identifying sexual mating alleles MAT1, MAT2 and understanding the genetic diversity based on DNA fingerprint of pot2, an inverted repeat transposon. Among 72 isolates, 44 isolates belonged to MAT1 type (male...
