Monoclonal antibodies reactive with either gag or fps portions of the wild-type Fujinami sarcoma virus transforming protein have been used to probe the structure of proteins encoded by mutant genomes constructed in vitro. The pattern of immunoreactivity suggests that the functional domain defined in genetic studies (Stone et al., Cell 37:549-558, 1984) corresponds to a discrete immunological do...
Given the scale of ongoing COVID-19 pandemic, need for reliable, scalable testing, and likelihood reagent shortages, especially in resource-poor settings, we have developed an RT-qPCR assay that relies on alternative to conventional viral reverse transcriptases, a thermostable transcriptase/DNA polymerase (RTX) (Ellefson et al., 2016). Here show RTX performs comparably other assays sanctioned b...
Because cells are constantly subjected to DNA damaging insults, DNA repair pathways are critical for genome integrity [1]. DNA damage recognition protein complexes (DRCs) recognize DNA damage and initiate DNA repair. The DNA-Damage Binding protein 2 (DDB2) complex is a DRC that initiates nucleotide excision repair (NER) of DNA damage caused by ultraviolet light (UV) [2]-[4]. Using a purified DD...
Single nucleotide polymorphisms (SNPs) are abundant in genomes of all species and biologically informative markers extensively used across broad scientific disciplines. Newly identified SNP markers are publicly available at an ever-increasing rate due to advancements in sequencing technologies. Efficient, cost-effective SNP genotyping methods to screen sample populations are in great demand in ...
PURPOSE OF REVIEW Tuberculosis (TB) incidence has declined ∼1.5% annually since 2000, but continued to affect 10.4 million individuals in 2015, with 1/3 remaining undiagnosed or underreported. The diagnosis of TB among those co-infected with HIV is challenging as TB remains the leading cause of death in such individuals. Accurate and rapid diagnosis of active TB will avert mortality in both adu...
HMOX-1 inhibits TGF-β-induced epithelial-mesenchymal transition in the MCF-7 breast cancer cell line
Epithelial‑mesenchymal transition (EMT) is a key mechanism underlying metastatic breast cancer. Reactive oxygen species (ROS) play an important role in EMT. Heme oxygenase‑1 (HMOX‑1) can reduce oxidative stress. However, the effect of HMOX‑1 on the EMT process in breast cancer cells is unknown. We treated the MCF‑7 breast cancer cell line with the HMOX‑1 inducer hemin and observed that hemin in...
Diagnostic systems based on reverse transcription (RT)-PCR are widely used for the detection of viral genomes in different human specimens. The application of internal controls (IC) to monitor each step of nucleic acid amplification is necessary to prevent false-negative results due to inhibition or human error. In this study, we designed various real-time RT-PCRs utilizing the coliphage MS2 re...
