    • Abstract

       

      Asthma is a chronic disease due to inflammation of the airways of lungs that is clinically characterized by variablesymptoms including wheezing, coughing and shortness of breath. Angiotensin I-converting enzyme (ACE) plays a majorrole in fibrous tissue formation and is highly expressed in lungs. The main aim of this research work was to study the roleof ACE insertion/deletion (I/D) polymorphism, rs4646994, in asthma in Pakistani patients. A total of 854 subjects,including 333 asthma patients and 521 ethnically matched controls, were studied. The ACE (I/D) polymorphism wasgenotyped using polymerase chain reaction (PCR). Chi-square, Fisher’s exact and Hardy–Weinberg equilibrium testswere used to compare groups. Homozygous insertion genotype II ($p \ lt 0.0001$, $OR=3.38$) and insertion allele (I) wassignificantly more frequent in Pakistani asthmatics than in healthy controls ($p=0.0007, OR=1.40$). The ID genotype ($p \lt 0.0001$, $OR=0.43$) and the deletion allele (D) were associated with protection of disease in Pakistani patients($p=0.0007, OR=0.71$). These data suggest the involvement of ACE I/D polymorphism in asthma risk in the Pakistanipopulation. This marker may be an important indication in the molecular mechanism of asthma and can become a usefultool in risk assessment and help in designing strategy to combat disease.

      Forthcoming Special issue.


    • To trigger further research on plant mitochondria, the Journal of Biosciences is bringing out a special issue titled "Plant Mitochondria: Properties and Interactions with Other Organelles".


      Plant mitochondria are quite distinct and have unique features, such as a cyanide-insensitive alternate pathway. They also interact with chloroplasts to optimize photosynthetic carbon assimilation.


      Submissions are welcome until 30 July 2023. The contributions can be original articles, short communications, reviews, or mini-reviews on any topic related to plant mitochondria.


      Authors can submit their articles online at https://www.editorialmanager.com/jbsc/default2.aspx
