Ultraconserved regions (UCRs) are non-protein coding gene sequences that are strictly conserved across among different species. Emerging evidence demonstrates that transcribed ultraconserved regions (TUCRs) encoding noncoding RNAs serve as regulators of gene expression. In recent decades, increasing evidence implicates the involvement of UCRs in carcinogenesis. The role of TUC.338 in cervical cancers was an oncogene in previous studies. Until now, the role of TUC.338 in colorectal cancers remains undefined...

We report a case of polymorphous hemangioendothelioma, a rare vascular neoplasm, arising in the liver of a 51-year-old woman. Microscopically, this neoplasm is characterized by a polymorphous blend of solid, primitive vascular and angiomatous areas in variable proportions. Polymorphous hemangioendothelioma is considered to be an intermediate-grade vascular neoplasm. In most of the reported cases, its occurrence has been in lymph nodes, but a few cases have been found in extranodal sites such as the mediastinum, spinal cord, and liver...

Multiple sclerosis (MS) is a very common disease of vital importance. In the MS treatment, some drugs such as fingolimod which help to protect nerves from damage are used. The main goal of the drug therapy in MS is to take control of the inflammation which leads to the destruction of myelin and axons in nerve cell and thus prevent and stop the progression of the disease. Fingolimod (FTY720) is an orally active immunomodulatory drug that has been used for the treatment of relapsing-remitting multiple sclerosis...

It is unclear if lymph node sampling in Wilms tumour, though critical for staging purposes, affects survival outcomes. The value of lymph node sampling in patients treated with neoadjuvant chemotherapy (NAC) is even more uncertain. We reviewed our institutional data to determine the impact of lymph node sampling on survival, as well as its role in the context of NAC. A total of 185 patients with Wilms tumour treated at our institution were included in this analysis. The number of nodes sampled (≤7, or >7), lymph node status (unknown, negative, or positive), pathological stage, and use of neoadjuvant chemotherapy were analysed for survival outcomes...

INTRODUCTION: There is a need for a precise and reliable imaging to improve the management of prostate cancer. In recent years the PET/CT with choline has changed the handling of prostate cancer in Europe, and it is commonly used for initial stratification or for the diagnosis of a biochemical recurrence, although it does not lack limitations. Other markers are being tested, including the ligand of prostate-specific membrane antigen (PSMA), that seems to offer encouraging prospects. The goal of this piece of work was to critically review the role of choline and PSMA PET/CT in prostate cancer...

On the same principle than total mesorectal excision in rectal cancer, the effect of complete mesocolic excision on short and long-term outcomes is actually evaluated for colonic adenocarcinoma. This method, usually performed for left colectomy, offers a surgical specimen of higher quality, with a larger number of lymph nodes harvested. For right colectomy, surgical specifications make it less common complete mesocolic excision and conventional surgery offer comparable outcomes, as regards to postoperative morbidity and mortality rates...

Ten-eleven translocation (TET) enzymes catalyze the oxidation of 5-methylcytosine (5-mC) to 5-hydroxymethylcytosine (5-hmC) and then to 5-formylcytosine (5-fC) and 5-carboxylcytosine (5-caC), resulting in genomic DNA demethylation. Decreased 5-hmC levels have been reported in a variety of cancers, and loss of 5-hmC might be considered an epigenetic hallmark of cancer. However, the prognostic value of decreased 5-hmC in cancers remain controversial. Here, a systematic review was performed by conducting an electronic search of PubMed, EMBASE, Web of Science and the Cochrane Library...

Immunohistochemistry (IHC) provides highly specific, reliable and attractive protein visualization. Correct performance and interpretation of an IHC-based multicolor labeling is challenging, especially when utilized for assessing interrelations between target proteins in the tissue with a high fat content such as the central nervous system (CNS). Our protocol represents a refinement of the standard immunolabeling technique particularly adjusted for detection of both structural and soluble proteins in the rat CNS and peripheral lymph nodes (LN) affected by neuroinflammation...

T-cell immunoglobulin and mucin-domain containing-3 (Tim-3) is an important immune regulatory molecule in cancer immune system. However, expression and function of Tim-3 in monocytes/macrophages in cancer progression mainly remain unclear. In this study, we analyzed Tim-3 levels in peripheral blood mononuclear cells (PBMCs) from 62 gastric cancer patients and 45 healthy controls using flow cytometry and then associated Tim-3 levels with clinical pathological data from patients. We found Tim-3 level was significantly upregulated in monocytes from gastric cancer patients compared with those from healthy controls, and that upregulated Tim-3 levels associated with depth of tumor invasion and tumor lymph node metastasis and advanced clinical stages of gastric cancer patients...
