Role of endoplasmic reticulum stress-related unfolded protein response and its implications in dengue virus infection for biomarker development.

Dengue virus (DENV) causes debilitating disease in humans, which varies at different rates in host cells, such as monocytes, macrophages, dendritic cells, Langerhans cells, and other cell types. Such heterogeneity in DENV infection in cells could be attributed to a range of factors, including host cell immune response, anti-viral cellular proteins, and virus mediated cellular autophagy. This review delineates an important feature of every cell, the unfolded protein response (UPR) that is attributed to the accumulation of several viral and unfolded/misfolded proteins, such as in DENV infection.

Genetic analysis of a Fanconi anemia case revealed the presence of FANCF mutation (exon 1;469>C-T) with implications to develop acute myeloid leukemia.

Background: Fanconi anemia (FA) is a rare genetic disorder and one of the most common inherited forms of aplastic anemia. FA is an autosomal recessive or X-linked genetic disorder that is characterized by typical physical malformations and haematopoietic anomalies. In most cases of FA, patients harbor homozygous or double heterozygous mutations in the FANCA (60-65%), FANCC (10-15%), FANCG (~ 10%), FANCD2 (3-6%) or FANCF (2%) genes in different ethnic populations, which leads to inherited bone marrow failure (IBMF).
