A computational study of the fold and stability of cytochrome c with implications for disease.

Cytochrome c (Cyt-c), encoded by the CYCS gene, is crucial for electron transport, peroxidase activity, and apoptosis. Mutations in CYCS cause thrombocytopenia 4 (THC4), a disorder with low platelet counts. We have, for instance, recently described six Italian families with five different heterozygous missense CYCS variants.

A novel de novo GFAP variant causes a juvenile-onset Alexander disease with bilateral vocal cord paralysis.

Alexander disease (AxD), an autosomal dominant leukodystrophy, is caused by mutations in the GFAP, the gene encoding glial fibrillary acidic protein (GFAP). The disease, classified by age of onset into infantile, juvenile, and adult forms, is characterized by white matter degeneration and astrocytic inclusions called Rosenthal fibers. A patient underwent clinical, radiological, and molecular analyses to confirm a suspected diagnosis of AxD.

In this study, we aim to identify a potent inhibitor for MPXV DNA polymerase (DNAP), a critical enzyme in the virus replication process. Using a computational drug repurposing approach, we performed a virtual screening of 1615 FDA-approved drugs based on drug-likeness and molecular docking against DNAP.

Inhibition of Monkeypox Virus DNA Polymerase Using Phytochemicals: Computational Studies of Drug-Likeness, Molecular Docking, Molecular Dynamics Simulation and Density Functional Theory.

The emergence of zoonotic monkeypox (MPX) disease, caused by the double-stranded DNA monkeypox virus (MPXV), has become a global threat. Due to unavailability of a specific small molecule drug for MPX, this study investigated phytochemicals to find potent and safe inhibitors of DNA Polymerase (DNA Pol), a poxvirus drug target due to its role in the viral life cycle. For that, 146 phytochemicals were screened through drug-likeness and molecular docking analyses.

Repurposing FDA approved drugs against monkeypox virus DNA dependent RNA polymerase: virtual screening, normal mode analysis and molecular dynamics simulation studies.

Zoonotic monkeypox disease, caused by the double-stranded DNA monkeypox virus, has become a global concern. Due to the absence of a specific small molecule drug for the disease, this report aims to identify potential inhibitor drugs for monkeypox. This study explores a drug repurposing strategy using virtual screening to evaluate 1615 FDA approved drugs against the monkeypox virus DNA dependent RNA polymerase subunit A6R.

Thrombocytopenia 4 (THC4): Six novel families with mutations of the cytochrome c gene.

Thrombocytopenia 4 (THC4) is an autosomal-dominant thrombocytopenia caused by mutations in CYCS, the gene encoding cytochrome c (CYCS), a small haeme protein essential for electron transport in mitochondria and cell apoptosis. THC4 is considered an extremely rare condition since only a few patients have been reported so far. These subjects presented mild thrombocytopenia and no or mild bleeding tendency.

Berberine ameliorates the progression of primary sclerosing cholangitis by activating farnesoid X receptor.

Primary sclerosing cholangitis (PSC) is a rare cholestatic disease characterized by biliary infiltration, hepatic fibrosis and bile duct destruction. To date, treatment options for PSC are very limited. Therefore, the current study is aimed to investigate the therapeutic potential of berberine (BBR) against PSC.

A computational and bioinformatic analysis of ACE2: an elucidation of its dual role in COVID-19 pathology and finding its associated partners as potential therapeutic targets.

Despite the continued global spread of the current COVID-19 pandemic, the nonavailability of a vaccine or targeted drug against this disease is still prevailing. The most established mechanism of viral entry into the body is considered to be via angiotensin-converting enzyme 2 (ACE2) acting as a receptor for viral spike protein thereby facilitating its entry in the cell. However, ACE2 is also involved in providing the protection from severe pathological changes.
