Natural selection and molecular evolution in primate PAX9 gene, a major determinant of tooth development.
Large differences in relation to dental size, number, and morphology among and within modern human populations and between modern humans and other primate species have been observed. Molecular studies have demonstrated that tooth development is under strict genetic control, but, the genetic basis of primate tooth variation remains unknown. The PAX9 gene, which codes for a paired domain-containi...
متن کاملUnderstanding the implications of the PAX9 gene in tooth development.
AIM Tooth agenesis is characterised by the congenital absence of one or more teeth. The Pax9 gene has been associated with nonsyndromic forms. MATERIALS AND METHODS To investigate the molecular mechanisms, we evaluated specific haplotypes frequency in exon 3 of the Pax9 gene in 26 patients and 21 controls, using an Italian population. RESULTS Presence of His239His and the Ala240Pro were con...
متن کاملCLONING AND EXPRESSION OF LEISHMANOLYSIN GENE FROM LEISHMANIA MAJOR IN PRIMATE CELL LINES
Leishmanolysin is a worldwide disease that is caused by different species of the genus Leishmania. Leishmanolysin, One of the genes expressed by Leishmania, appears to be an ideal candidate for genetic vaccination. In this study, a full length sequence, which encodes Leishmanolysin functionally critical regions (amino acids 100-579), was cloned from a Leishmania strain endemic to Iran. Analysis...

چکیده پایان نامه (شامل خلاصه، اهداف، روش های اجرا و نتایج به دست آمده): کار جمع آوری گو یش های محلی در سال های اخیر شتاب امیدوار کننده ای به خود گرفته است. شاید از بارزترین اهداف جمع آوری گویش های مختلف، ثبت و ضبط آن، جلوگیری از نابودی و مهمتر از همه حل مشکلات دستوری زبان رسمی باشد. دقت در فرآیند های زبانی گویش های محلی نوع ارتباط مردم نواحی مختلف با پیرامون نشان را به ما نشان خواهد داد. از س...
Natural selection on a major armor gene in threespine stickleback.
Experimental estimates of the effects of selection on genes determining adaptive traits add to our understanding of the mechanisms of evolution. We measured selection on genotypes of the Ectodysplasin locus, which underlie differences in lateral plates in threespine stickleback fish. A derived allele (low) causing reduced plate number has been fixed repeatedly after marine stickleback colonized...
