The most frequent form of monogenic hypercholesterolemia, also known as Familial Hypercholesterolemia (FH), is characterized by plasma accumulation of cholesterol transported in Low Density Lipoproteins (LDLs). FH has a co-dominant transmission with a gene-dosage effect. FH heterozygotes have levels of plasma LDL-cholesterol (LDL-C) twice normal and present xanthomas and coronary heart disease (CHD)...
Mayer–Rokitansky–Küster–Hauser (MRKH) syndrome is a congenital defect of the Müllerian ducts characterized by uterovaginal agenesis and underdeveloped female genital organs. This paper is a tribute to the contributors of this condition — August Franz Joseph Karl Mayer, Karl Freiherr von Rokitansky, Hermann Küster and Georges André Hauser. In addition to their contributions, we have discussed findings...
Krabbe disease or globoid cell leukodystrophy is one of the classic genetic lysosomal storage diseases with autosomal recessive inheritance that affects both central and peripheral nervous systems in several species including humans, rhesus macaques, dogs, mice, and sheep. Since its identification in 1916, lots of scientific investigations were made to define the cause, to evaluate the molecular mechanisms...
Joseph Merrick, the Elephant Man, presented to the Royal London Hospital in 1884 with an obscure condition that puzzled his contemporaries, and fascinates clinicians to this day. Throughout the 1900s, a number of theories were advanced to explain the numerous growths that covered his body: neurofibromatosis, Proteus syndrome, and a combination of childhood injury, fibrous dysplasia, and pyarthrosis...
“Healing is best accomplished when art and science are conjoined, when body and spirit are probed together”, says Bernard Lown, in his book “The Lost Art of Healing”.Art has long been a witness to disease either through diseases which affected artists or diseases afflicting objects of their art. In particular, artists have often portrayed genetic disorders and malformations in their work. Sometimes...
Leber hereditary optic neuropathy (LHON) is a genetic, maternally inherited disease caused by point mutations in the mitochondrial genome. LHON patients present with sudden, painless and usually bilateral loss of vision caused by optic nerve atrophy. The first clinical description of the disease was made by Theodor Leber, a German ophthalmologist, in 1871. Here we present his thorough notes about...
The world is seemingly facing a global increase in people suffering from diabetes especially in developing countries. The worldwide occurrence of diabetes for all age groups in year 2000 was estimated to be 2.8% and this number is most certainly expected to rise to 4.4% by 2030. Maturity-onset of diabetes of the young, or MODY, is a form of monogenic diabetes that is caused by mutations occurring...
Henri de Toulouse-Lautrec, a 19th century artist celebrated for his depictions of the Moulin Rouge and Parisian nightlife, suffered from an unknown disorder. His symptoms were not only rare, but also difficult to determine. Both during his lifetime and following his death potential diagnoses have proved controversial, including the most popularly supported suggestion of pycnodysostosis. Addressing...
Lysosomal storage disorders (LSDs) are a group of rare genetic diseases, generally caused by a deficiency of specific lysosomal enzymes, which results in abnormal accumulation of undegraded substrates. The first clinical reports describing what were later shown to be LSDs were published more than a hundred years ago. In general, the history and pathophysiology of LSDs has impacted on our current knowledge...
Glutamate racemase (MurI) converts l-glutamate into d-glutamate which is an essential component of peptidoglycan in bacteria. The gene encoding glutamate racemase, murI has been shown to be essential for the growth of a number of bacterial species including Escherichia coli. However, in some Gram-positive species d-amino acid transaminase (Dat) can also convert l-glutamate into d-glutamate thus rendering...
HSP70 and HSP90 are the most important heat shock proteins (HSPs), which play the key roles in the cell as molecular chaperones and may involve in metabolic detoxification. The present research has obtained full-length cDNAs of genes HSP70 and HSP90 from the clam Ruditapes philippinarum and studied the transcriptional responses of the two genes when exposed to benzo(a)pyrene (BaP). The full-length...
Stroke is a global health problem and a leading cause of disability worldwide. There have been numerable studies undertaking research on different aspects of ischaemic stroke employing various epidemiological, clinical and molecular parameters. Nevertheless ischaemic stroke being a complex disorder with different subtypes demands equal attention towards its subtypes too. Since there has been enough...
Despite the increasing evidence of the importance of microRNAs (miRNAs) in the regulation of multiple biological processes, the molecular bases supporting this regulation are still barely understood in crustaceans. Therefore, the molecular characterization and transcriptome modulation of the miRNA biogenesis pathway were evaluated in the salmon louse Caligus rogercresseyi, an ectoparasite that constitutes...
Eye-field transcription factors (EFTFs) are a set of genes that compose a regulatory network for eye development in animals, which are highly conserved among various animal phyla. To investigate the processes of conservation and diversification of the transcription factors for eye development, we examined the structural changes in the EFTF proteins by estimating the ancestral sequences with the available...
Mobile elements are responsible for ~45% of the human genome. Among them is the Alu element, accounting for 10% of the human genome (>1.1million copies). Several studies of Alu elements have reported that they are frequently involved in human genetic diseases and genomic rearrangements. In this study, we investigated the AluS subfamily, which is a relatively old Alu subfamily and has the highest...
Enhancers are DNA sequences that enhance gene transcription in a position- and orientation-independent manner. Many enhancers controlling somatic gene expression have been described. Enhancers controlling germline expression have remained rare. Here we report the identification of V35 as a first exonic germline enhancer in vertebrates. V35 constitutes the first 35bp of exon 1 of the medaka vasa gene...
The aim of the present study was to investigate whether soybean oligosaccharides (SO) protects heart function against myocardium ischemia reperfusion (MIR) injury. Hearts were 20min global ischemia and 50min reperfusion. Rats were fed for 30days with saline (sham and MIR groups) or the SO (200 or 400mg/kg body weight, daily). At the end of 30days, the left main coronary artery was occluded for 30min,...
The most common malignancy in women is breast cancer. Drug resistance in the treatment of cancer still remains a major clinical concern. Resistance to tamoxifen is seen in half of the recurrences in breast cancer. The anti-estrogen tamoxifen gains agonistic property by transactivating ERα. PAK1-mediated phosphorylation of serine 305 (S305) of ERα leads to resistance to tamoxifen. In our study, PAK1-induced...
