Cancer

Lung adenosquamous cell carcinomas (ASCs) is a rare variant of NSCLC with a poorer prognosis and fewer treatment option than the more common variants. PD-L1 expression is reported to be the predictor of clinical response in trials of NSCLC.

Primary mediastinal large B-cell lymphoma (PMLBCL) is recognized as a distinct clinicopathological entity in the current World Health Organization classification of lymphoid neoplasms (Swerdlow et al, 2016). Gene expression profiling studies have confirmed a distinct signature in PMLBCL that differs from diffuse large B-cell lymphoma, not otherwise specified (DLBCL, NOS) and partially overlaps with that found in classical Hodgkin lymphoma (Savage et al, 2003; Bea et al, 2005).

Tumor subclasses differ according to the genotypes and phenotypes of malignant cells as well as the composition of the tumor

Abstract: Objective: To investigate the potential involvement of secreted protein acidic and rich in cysteine (SPARC) in the progression of the breast tumor and to determine its association with outcome variables and matrix metalloproteinases (MMPs) expression in patients with breast carcinoma (BC). Methods: SPARC expression was examined in 8 pairs of BC tissues and surrounding normal tissues at mRNA and protein levels by qRT-PCR, RNAscope in situ hybridization (ISH), Western blotting, and immunohistochemistry techniques.

Cancer-associated fibroblasts (CAFs) play important roles in cancer progression through their complex interactions with cancer cells.

The intestine is maintained by stem cells, marked by LGR5 expression, located at the base of crypts. Genetically engineered mouse models have provided information about marker genes and stem cell pathways. Less is known about human intestinal stem cells due to difficulty detecting and isolating these cells.

Intratumoral heterogeneity is a major obstacle to cancer treatment and a significant confounding factor in bulk-tumor profiling. We performed an unbiased analysis of transcriptional heterogeneity in colorectal tumors and their microenvironments using single-cell RNA-seq from 11 primary colorectal tumors and matched normal mucosa. To robustly cluster single-cell transcriptomes, we developed reference component analysis (RCA), an algorithm that substantially improves clustering accuracy.

ETS family gene fusions are common in prostate cancer and molecularly define a tumor subset. ERG is the most commonly rearranged member, leading to its overexpression,

To more fully characterize the clinical and pathologic spectrum of a recently described tumor entity of the sinonasal tract characterized by loss of nuclear expression of SMARCB1 (INI1), we analyzed 39 SMARCB1-deficient sinonasal carcinomas collected from multiple medical centers. The tumors affected 23 males and 16 females with an age range of 19 to 89 years (median, 52).
