Molecular insights of the G2019S substitution in LRRK2 kinase domain associated with Parkinson's disease: A molecular dynamics simulation approach.
( Elsevier , 2019 , Article)The G2019S substitution in the Leucine-rich repeat kinase 2 (LRRK2) is significantly associated with Parkinson's disease (PD). This substitution was identified in both familial and sporadic forms of PD with a higher ... -
Molecular investigation of waterborne protozoan contamination using marine Demospongiae
( Elsevier , 2024 , Article)Sponges play important role within aquatic ecosystems due to their diverse abilities including filter-based feeding mechanisms. Hence, this study evaluated the potential use of sponges as ecological biomonitors for water ... -
Molecular Mechanisms of Colon Cancer Progression and Metastasis: Recent Insights and Advancements.
( MDPI , 2020 , Article Review)Colorectal cancer (CRC), the third most common type of cancer, is the second leading cause of cancer-related mortality rates worldwide. Although modern research was able to shed light on the pathogenesis of CRC and provide ... -
Molecular Subtyping of Blastocystis from Diverse Animals in the United Arab Emirates.
( Elsevier , 2019 , Article)The contribution of Blastocystis from non-human hosts to zoonotic transmission is only partly known. The objective of this study was to determine the distribution of Blastocystis genetic subtypes in different animal species ... -
The mosquito melanization response requires hierarchical activation of non-catalytic clip domain serine protease homologs.
( Public Library of Science , 2019 , Article)Serine protease cascades regulate important insect immune responses namely melanization and Toll pathway activation. An important component of these cascades are clip-domain serine protease homologs (cSPHs), which are ... -
mRNA-1273 COVID-19 vaccine effectiveness against the B.1.1.7 and B.1.351 variants and severe COVID-19 disease in Qatar
(2021 , Article)The SARS-CoV-2 pandemic continues to be a global health concern. The mRNA-1273 (Moderna) vaccine was reported to have an efficacy of 94.1% at preventing symptomatic COVID-19 due to infection with ‘wild-type’ variants in a ... -
Mutational landscape of K-Ras substitutions at 12th position-a systematic molecular dynamics approach
( Taylor and Francis , 2020 , Article)K-Ras is a small GTPase and acts as a molecular switch by recruiting GEFs and GAPs, and alternates between the inert GDP-bound and the dynamic GTP-bound forms. The amino acid at position 12 of K-Ras is a hot spot for ... -
