conclusions imp3 immunoreactivity was associated with poor differentiation of tumor yet not associated with tumor size depth of invasion or lymph node involvement. results immunoreactivity pattern of imp3 was cytoplasmic in different clinicopathologic findings. among different clinicopathologic findings, we found a statistical relationship between tumor differentiation and imp3 (p = 0.047); so ...

OBJECTIVE Superficial tumors including Ta, Tis, and T1 make up 75% of urothelial carcinomas of the bladder. While the behavior of these superficial urothelial cancers is relatively benign, invasive tumors have a significant mortality rate. However, Ta and T1 tumors might display different biological behavior. There is therefore a great need for biomarkers that can accurately distinguish the beh...

The utility of combination with CK5/6, IMP3 and TTF1 to differentiate among reactive mesothelial cells (RMs), metastatic adenocarcinoma of lung (LAC) and non-lung (NLAC) origin was investigated by using immunocytochemistry (ICC) and conventional PCR (C-PCR) in pleural effusion. A total of 108 cell blocks (32 RMs, 51 LAC and 25 NLAC were evaluated by ICC for CK5/6, IMP3 and TTF1 protein expressi...

BACKGROUND Lung cancer most often presents as an inoperable tumour and the diagnosis is usually performed on a small biopsy/cytology specimen. In the group of non small cell lung cancer - not otherwise specified, adenocarcinoma phenotype can be determined immunohistochemically using TTF-1 and Napsin A. Expression of oncofetal protein IMP3 in human cancer is associated with poor differentiation ...

The aim of the present study was to investigate the expression and clinical significance of oncofetal protein insulin-like growth factor (IGF) II mRNA-binding protein 3 (IMP3) in the differentiation of gastroenteropancreatic neuroendocrine neoplasm (GEP-NEN). A total of 162 patients who were diagnosed with GEP-NEN, and who underwent surgical or endoscopic resection from January 2006 to March 20...

The IASLC/ATS/ERS classification system was proposed in 2011 to improve the histological subtypes of lung adenocarcinoma, while the prognostic value of the combination of histological predominant subtypes is not consistent. IMP3 is an oncofetal protein which has been proved associated with aggressive tumor behavior in malignancies, but few reports were investigated in lung adenocarcinoma. The a...

Expression of p16 has been established as a good surrogate marker for high-risk human papillomavirus (HPV) infection in oropharyngeal squamous cell carcinoma (OPSCC) patients, and it has been associated with an improved prognosis, irrespective of the actual HPV status. Conversely, the human insulin-like growth factor II mRNA binding protein 3 (IMP3) has been related to aggressiveness in several...

Expression of the stress-induced ligands MICA, MICB and ULBP 1-6 are up-regulated as a cellular response to DNA damage, excessive proliferation or viral infection; thereby, they enable recognition and annihilation by immune cells that express the powerful activating receptor NKG2D. This receptor is present not exclusively, but primarily on NK cells. Knowledge about the regulatory mechanisms con...

Purpose: Insulin-like growth factor II mRNA-binding protein 3 (IMP3) is an oncofetal protein expressed in diverse malignancies. This study aimed to investigate the prognostic value of IMP3 in urological cancers. Methods: Eligible studies were sought in PubMed, Embase, Cochrane Collaboration and Wanfang databases. Pooled hazard ratios (HRs) with their 95% confidence intervals (CIs) were used to ...

Osteosarcoma is a high-grade malignant bone tumor that manifests ingravescent clinical behavior. The intrinsic events that confer malignant properties on osteosarcoma cells have remained unclear, however. We previously established two lines of mouse osteosarcoma cells: AX cells, which are able to form tumors in syngeneic mice, and AXT cells, which were derived from such tumors and acquired an i...
