The Caenorhabditis elegans DPF‐3 and human DPP4 have tripeptidyl peptidase activity

open access: yesFEBS Letters, EarlyView.
The dipeptidyl peptidase IV (DPPIV) family comprises serine proteases classically defined by their ability to remove dipeptides from the N‐termini of substrates, a feature that gave the family its name. Here, we report the discovery of a previously unrecognized tripeptidyl peptidase activity in DPPIV family members from two different species.

Vaccines against toxoplasma gondii : challenges and opportunities [PDF]

open access: yes, 2009
Development of vaccines against Toxoplasma gondii infection in humans is of high priority, given the high burden of disease in some areas of the world like South America, and the lack of effective drugs with few adverse effects.

The zinc finger domains of PARP‐1 are selectively and potently inhibited by the Au(I)‐based drugs sodium aurothiomalate and aurothioglucose

open access: yesFEBS Letters, EarlyView.
PARP‐1 is a key enzyme in the DNA damage response, and its inhibition induces cancer cell death via synthetic lethality. Au(I)‐based drugs, such as aurothioglucose and sodium aurothiomalate, block PARP‐1's DNA‐dependent activity by targeting its zinc finger domains.

Effects of Genetically Modified corn on human health

open access: yesPlant Biotechnology Persa, 2020
Genetic modification is a specific part of gene technology that changes the genetic structure of living organisms, such as animals, plants, or microorganisms. Genetically Modified, is known with such names as Transgenic or Transgenic.

Removing N-terminal sequences in pre-S1 domain enhanced antibody and B-cell responses by an HBV large surface antigen DNA vaccine. [PDF]

open access: yesPLoS ONE, 2012
Although the use of recombinant hepatitis B virus surface (HBsAg) protein vaccine has successfully reduced global hepatitis B infection, there are still a number of vaccine recipients who do not develop detectable antibody responses.

Screening for the optimal siRNA targeting a novel gene (HA117) and construction and evaluation of a derivative recombinant adenovirus [PDF]

open access: yes, 2010
We found a novel gene named as HA117 in our previous research. At this study, we screened for an optimal siRNA targeting the novel gene HA117 using the pSOS-HUS method, verified the results of pSOS-HUS siRNA screening for optimal affinity for the target ...

Claspin and the Activated Form of ATR-ATRIP Collaborate in the Activation of Chk1 [PDF]

open access: yes, 2004
Claspin is necessary for the ATR-dependent activation of Chk1 in Xenopus egg extracts containing incompletely replicated DNA. ATR possesses a regulatory partner called ATRIP. We have studied the respective roles of ATR-ATRIP and Claspin in the activation

Substrate specificity of Burkholderia pseudomallei multidrug transporters is influenced by the hydrophilic patch in the substrate‐binding pocket

open access: yesFEBS Letters, EarlyView.
Multidrug transporters BpeB and BpeF from the Gram‐negative pathogen Burkholderia pseudomallei have a hydrophilic patch in their substrate‐binding pocket. Drug susceptibility tests and growth curve analyses using an Escherichia coli recombinant expression system revealed that the hydrophilic patches of BpeB and BpeF are involved in the substrate ...

Recombinant DNA Molecules of Bacteriophage phi X174 [PDF]

open access: yes, 1975
phi X174 DNA structures containing two different parental genomes were detected genetically and examined by electron microscopy. These structures consisted of two monomeric double-stranded DNA molecules linked in a figure 8 configuration.

Expression of functional recombinant human tissue transglutaminase (TG2) using the bac-to-bac baculovirus expression system [PDF]

open access: yes, 2016
Purpose: Tissue transglutaminase (TG2) is a unique multifunctional enzyme. The enzyme possesses enzymatic activities such as transamidation/crosslinking and non-enzymatic functions such as cell migration and signal transduction.
