In this study, we have identified a novel Nedd4-like ubiquitin ligase, BUL1, as the host factor involved in budding of type D retrovirus Mason-Pfizer monkey virus (M-PMV). Overexpression of BUL1 enhanced virus particle release, while a BUL1 mutant in which a W to G substitution was introduced into a WW domain, W791G, lost the ability to bind to the viral Gag protein and abolished its ability to...

The budding reactions of a number of enveloped viruses use the cellular machinery involved in the formation of the luminal vesicles of endosomal multivesicular bodies (MVB). Budding of these viruses is dependent on the presence of specific late-domain motifs in membrane-associated viral proteins. Such budding reactions usually involve ubiquitin and are blocked by expression of an ATPase-deficie...

UNLABELLED It has been reported that poorly-differentiated clusters of cancer cells at the invasive front, namely "tumour budding", may reflect malignancy of colorectal cancer. The aim of the present study was to evaluate the activity of cathepsin D and B in tumours and in normal mucosa from pT3 and G2 colorectal cancers, and to analyse their association with tumour budding at the invasion fron...

IMP3 is associated with lymph node metastasis and TNM stage and is a good independent prognostic biomarker for colorectal cancer (CRC). However, the expression status and clinical implication of IMP3 in biopsy specimens have not yet been studied. We aim to address whether the presence of IMP3 expression in preoperative biopsies of CRC could predict lymph node metastasis and TNM stage. In this s...

Background: Colorectal adenocarcinoma (CA) is one of the most common malignancies. Tumor budding (TB) status associated with poor prognosis in patients. Prognosis influenced by clinicopathological profile. This study aims to determine relationship between profile TB CA at Dr. Cipto Mangunkusumo General National Hospital.Method: A cross-sectional retrospective analytic using secondary data form ...

  Background: Oral lichen planus (OLP) has been classified as a pre-malignant condition. Matrix metalloproteinase-13 (MMP-13) or collagenase-3 may play a key role in cancer development. The aim of this study was to compare serum and saliva MMP-13 between patients with oral lichen planus (OLP) and oral squamous cell carcinoma (OSCC).   Methods : This cross sectional study was performed on 30 pat...
