Increasing evidence indicates that long non-coding RNAs (lncRNAs) regulate gene or protein expression; however, their function in the progression of hepatic fibrosis remains unclear. Hepatic fibrosis is a continuous wound-healing process caused by numerous chronic hepatic diseases, and the activation of hepatic stellate cells (HSCs) is generally considered to be a pivotal step in hepatic fibrosis. In the process of hepatic fibrosis, some lncRNAs regulates diverse cellular processes. Read More

Immunoglobulin heavy chain (IgH) translocations are common and early oncogenic events in B cell and plasma cell malignancies including B cell non-Hodgkin's lymphoma (NHL) and multiple myeloma (MM). IgH translocations bring oncogenes into close proximity with potent enhancer elements within the IgH locus, leading to oncogene up-regulation. As IgH enhancer activity is tightly controlled by B cell lineage-specific signaling and transcriptional networks, we hypothesized that IgH enhancers are potentially druggable targets/elements.

Introduction: Plasmacytoma describes a neoplastic proliferation of plasma cells affecting different groups of patients according to location, and may demonstrate heterogeneous tumor progression and survival rate. The present article describes a case of solitary plasmacytoma in the mandible
Presentation Of Case: A 57-year-old male smoker was referred to the oral and maxillofacial service with extensive injury, approximately 4-5 cm in size, involving the anterior inferior region of mandible. After confirming diagnosis of plasmacytoma through incisional biopsy, because it was a recurrent lesion, excision of the lesion was performed through marginal resection of the mandible under general anesthesia.

Lymphomas associated with breast implants are rare, with the most common being anaplastic large cell lymphoma (ALCL). Non-ALCL breast implant-associated lymphomas are even more rare, with only a small handful of such neoplasms reported to date. Given the need to better understand these pathologies as well as the increasing clinical and media attention to these diseases, we review the available literature of hematolymphoid neoplasms other than ALCL associated with breast implants and describe the first case of a patient diagnosed with a primary breast implant-associated plasmacytoma.

Plasma cell neoplasms may have a spectrum of clinical presentation ranging from asymptomatic proliferation to single/multiple mass lesions in medullary/ extramedullary sites. Extramedullary plasmacytoma (EMP) is a rare tumor of the soft tissue without theinvolvement of bone marrow which most commonly affects the head and neck region and may precede multiple myeloma (MM) (1). Thyroid can rarely be a site for EMP or may be infiltrated by systemic multiple myeloma. Read More

Overall, 508 samples from 264 newly diagnosed PCN patients, were studied. CTPC were detected in PB of all active multiple myeloma (MM; 100%), and smoldering MM (SMM) patients (100%), and in more than half (59%) monoclonal gammopathy of undetermined significance (MGUS) cases (p <0.

Aims: Epstein-Barr virus (EBV) expression has been reported in several hematopoietic and non-hematopoietic disorders but its expression in plasma cell neoplasms has been largely limited to immunodeficiency-related cases such as in the setting of post-organ transplantation or human immunodeficiency virus (HIV) infection. The aim of this study is to evaluate the association of EBV with plasma cell neoplasms, mainly in immunocompetent patients.
Methods And Results: We retrospectively studied 147 cases of patients with different plasma cell neoplasms (109 plasma cell myelomas, 22 plasmacytomas, and 16 monoclonal gammopathy cases). Read More

Urothelial carcinoma is a morphologically and genomically heterogeneous disease that exhibits a wide spectrum of morphologic features and molecular alterations and subtypes. Classic urothelial carcinoma (not otherwise specified) is the most common tumor type that develops in the urinary bladder but many, well-documented, variant histologies are commonly encountered in approximately one-third of invasive urothelial carcinoma, including squamous, glandular, micropapillary, sarcomatoid, small cell/neuroendocrine, clear cell, lymphoepithelioma-like, and plasmacytoid types, among others. In this review, we provide an update on the molecular advances in urothelial carcinoma and some of its variant histologies. Read More

Background: Parasellar plasmacytomas are rare tumors arising from the sellar region that should be considered in differential diagnosis for lesions involving the sella and clivus. Prior to surgical pathologic examination, parasellar plasmacytomas are often misdiagnosed as invasive pituitary adenomas or chordomas due to the similarity of clinical presentation and imaging findings.
Methods: We retrospectively reviewed 5 patients with parasellar plasmacytoma who underwent endonasal endoscopic tumor resection in Beijing Tiantan Hospital between January 2008 and January 2018. Read More

A query regarding the definition and the classification of solitary plasmacytoma is apparently still pending. The clinical course, the response to treatment and the propensity to progress to plasma cell myeloma, are all a function of the classification which must be established on a firm basis. Solitary plasmacytoma should be recognized in the continuum of the plasma cell neoplasms. Read More

Plasmacytomas are discrete, B cell-derived, round cell tumours that sometimes are difficult to distinguish from canine cutaneous histiocytomas or T cell lymphosarcomas (lymphomas). Diagnosis of plasmacytomas relies on morphological observations and immunohistochemistry for multiple myeloma oncogene-1 (MUM-1) and cluster of differentiation 3 (CD3). Clonality testing often is used as an adjunct diagnostic tool to examine lymphoproliferative diseases. Read More

In conclusion, extramedullary plasmacytoma (EMPs) initially develop as localized disease. These tumors are quite sensitive to radiotherapy (RT) and the response is often complete recovery after RT. In addition, highly sensitive, conformal radiosurgery can be preferred to conventional RT; however, further studies are needed to define indications and therapeutic fractions in stereotactic RT of plasmacytoma since guidelines and clinical trials are lacking.

Purpose: The aim of our study was to validate the sway of long noncoding RNA (lncRNA) plasmacytoma variant translocation 1 (PVT1) on the metabolism and growth of bladder cancer cells by microRNA-31 (miR-31)/cyclin-dependent kinase 1 ( CDK1).
Methods: The Gene Expression Omnibus database was used for analyzing the differentially expressed lncRNA and messenger RNA (mRNA) in bladder cancer tissues, with the highly expressed lncRNA PVT1 and mRNA CDK1 screened out. The expression level of PVT1 was detected by quantitative reverse-transcription polymerase chain reaction, cell viability by Cell Counting Kit-8 assay, cell proliferation and scratch by 5-bromo-2'-deoxyuridine assay, cell migration and invasion by transwell assays, the expression level of CDK1 by immunohistochemistry and western blot analysis, transcription factor targeting by dual-luciferase assay, and the effect of PVT1 on bladder cancer growth by nude mice tumor formation experiment.
