Effective treatment strategies against Ebola virus

Ebola virus (EBOV), a member of order Mononegavirales is most famous for causing the endemics of hemorrhagic fever in different countries of the world. Various effective treatment for EBOV are available presently but different clinical trials and experimental studies on animal models are ongoing for this purpose. Results from different studies showed that selective vaccines and therapeutic drugs have potential to interfere the viral life events within host cell in order to inhibit its replication. Various pre-clinical trials in this regard are proved successful on non-human primates (NHPs) and found to be significant in inhibiting EBOV infections. It is the need of hour to develop effective vaccines against Ebola virus to combat this problem as soon as possible. The present article is a brief review on potential treatment strategies against Ebola virus

Prevalence of RECQL germline variants in Pakistani early-onset and familial breast cancer patients

Background!#!The RecQ Like Helicase (RECQL) gene has previously been shown to predispose to breast cancer mainly in European populations, in particular to estrogen receptor (ER) and/or progesterone receptor (PR) positive tumor. Here, we investigated the contribution of pathogenic RECQL germline variants to hereditary breast cancer in early-onset and familial breast cancer patients from Pakistan.!##!Methods!#!Comprehensive RECQL variant analysis was performed in 302 BRCA1 and BRCA2 negative patients with ER and/or PR positive breast tumors using denaturing high-performance liquid chromatography followed by DNA sequencing. Novel variants were classified using Sherloc guidelines.!##!Results!#!One novel pathogenic protein-truncating variant (p.W75*) was identified in a 37-year-old familial breast cancer patient. The pathogenic variant frequencies were 0.3% (1/302) in early-onset and familial breast cancer patients and 0.8% (1/133) in familial patients. Further, three novel variants of unknown significance, p.I141F, p.S182S, and p.C475C, were identified in familial breast cancer patients at the age of 47, 68, and 47 respectively. All variants were absent in 250 controls.!##!Conclusions!#!Our data suggest that the RECQL gene plays a negligible role in breast cancer predisposition in Pakistan

Serum from CCl₄-induced acute rat injury model induces differentiation of ADSCs towards hepatic cells and reduces liver fibrosis

<p>Cellular therapies hold promise to alleviate liver diseases. This study explored the potential of allogenic serum isolated from rat with acute CCl₄ injury to differentiate adipose derived stem cells (ADSCs) towards hepatic lineage. Acute liver injury was induced by CCl₄ which caused significant increase in serum levels of VEGF, SDF1α and EGF. ADSCs were preconditioned with 3% serum isolated from normal and acute liver injury models. ADSCs showed enhanced expression of hepatic markers (AFP, albumin, CK8 and CK19). These differentiated ADSCs were transplanted intra-hepatically in CCl₄-induced liver fibrosis model. After one month of transplantation, fibrosis and liver functions (alkaline phosphatase, ALAT and bilirubin) showed marked improvement in acute injury group. Elevated expression of hepatic (AFP, albumin, CK 18 and HNF4a) and pro survival markers (PCNA and VEGF) and improvement in liver architecture as deduced from results of alpha smooth muscle actin, Sirius red and Masson’s trichome staining was observed.</p
