Prostate adenocarcinoma (PCa) and melanoma are paradigmatic examples of tumors that are either poorly or highly sensitive to therapies based on monoclonal antibodies directed against regulatory pathways in T lymphocytes [i.e., immune checkpoint blockade (ICB)]. Yet, approximately 40% of melanoma patients are resistant or acquire resistance to ICB. What characterize the microenvironment of PCa and ICB-resistant melanoma are a scanty cytotoxic T cell infiltrate and a strong immune suppression, respectively. Here, we compare the tumor microenvironment in these two subgroups of cancer patients, focusing on some among the most represented immune checkpoint molecules: cytotoxic T lymphocyte-associated antigen-4, programmed death-1, lymphocyte activation gene-3, and T cell immunoglobulin and mucin-domain containing-3...

The T‑cell immunoglobulin and mucin domain‑containing protein 3 (Tim‑3)/galectin 9 (Gal‑9) pathway, which serves a pivotal role in immune regulation, is similar to the programmed death (PD)‑1/PD‑ligand 1 pathway. Recent evidence has suggested that Tim‑3 is differentially regulated in a variety of tumors and is a potential therapeutic target. The aim of the present study was to evaluate Tim‑3 and Gal‑9 expression and cluster of differentiation (CD)3+, CD8+ and forkhead box (FOX)p3+ T cell tumor‑infiltration in gastric cancer, as well as their impact on prognosis...

Signet ring cell carcinoma (SRCC) of the ovary is most commonly metastatic from a primary lesion. Primary ovarian SRCC is rare, and the distinction between primary and metastatic SRCC of the ovary may be difficult. We herein present a case of primary SRCC of the ovary in a 54-year-old woman presenting with a right ovarian mass sized 20.5×16.5×11.5 cm. Total abdominal hysterectomy with bilateral salpingo-oophorectomy, partial omentectomy and incidental appendectomy were performed. Upon histological examination, mucinous carcinoma composed predominantly of signet ring cells was observed in the right ovary...

Previously we have demonstrated that the GJ protein connexin 30.2 (Cx30.2) is expressed in pancreatic beta cells and endothelial cells (ECs) of the islet. In the present study, we address whether Cx30.2 is expressed in the exocrine pancreas, including its vascular system. For this, adult mouse pancreatic sections were double labeled with specific antibodies against Cx30.2 and CD31, an endothelial cell marker, or with anti-α-actin smooth muscle, a smooth muscle cell (SMC) marker or anti-mucin-1, a marker of epithelial ductal cells, using immunofluorescence (IF) studies...

Rosmarinic acid (RA) is a natural phenylpropanoid with numerous pharmacological activities. Because of limited studies of the effects of RA action in gastric cancer cells we examined how 100 and 200 μM acid influences MMPs, TIMPs, collagen, MUC1 and specific sugar antigens in gastric adenocarcinoma CRL-1739 cells. We revealed inhibitory effect of RA on MMP-9 activity what was correlated with increased collagen type I expression, main ECM substrate degraded by MMPs. Tissue inhibitor of MMPs, TIMP-1 but not TIMP-2 was significantly decreased on the protein level and increased on mRNA level by RA action what can suggest TIMP-1 independent inhibitory action of an acid on MMP-9 activity...

This paper reports on a sensitive and selective method for the detection of Michigan Cancer Foundation-7 (MCF-7) human breast cancer cells and MUC1 biomarker by using an aptamer-based sandwich assay. A biocompatible nanocomposite consisting of multiwall carbon nanotubes (MWCNT) and poly(glutamic acid) is placed on a glassy carbon electrode (GCE). The sandwich assay relies on the use of a mucin 1 (MUC1)-binding aptamer that is first immobilized on the surface of modified GCE. Another aptamer (labeled with silver nanoparticles) is applied for secondary recognition of MCF-7 cells in order to increase selectivity and produce an amplified signal...

Ciliated muconodular papillary tumors (CMPTs) are characterized by tripartite cellular components of ciliated columnar cells, mucinous cells, and basal cells with predominantly papillary architecture. Some peripheral lung nodules may not demonstrate papillary architecture and tripartite cells that show bronchiolar differentiation; these nodules are termed "CMPTs with non-classic morphology" by some authors. To validate the rationality of "non-classic" CMPTs and to analyze the clinicopathological features of CMPTs, we enrolled 21 cases of lung nodules, comprising classic CMPTs (n=11) and so-called "non-classic" CMPTs (n=10)...

Arsenic poisoning is a worldwide problem. Thus, we studied the effects of arsenic trioxide (ATO) administration on a 1,2-dimethylhydrazine (DMH)-induced preneoplasic colon carcinogenesis model. Mice were separated into four study groups; the control group received only vehicles. The ATO group received daily a 2.5 mg kg-1 dose for 4 weeks. The DMH group received DMH (20 mg kg-1 ) twice in two weeks. The third group (D-ATO) had the same as the DMH group with ATO administration starting at week 10. At the end of 14 weeks, colons from sacrificed mice were taken, segmented into distal and proximal and subjected to aberrant crypt foci (ACF), aberrant crypt (AC) counting, alcian blue, H&E and Hoechst histological study and lastly oxidative stress marker analysis as well as mitochondrial swelling assessment...

Background: The associated increase in the lipopolysaccharide (LPS) levels and uremic toxins in chronic kidney disease (CKD) has shifted the way we focus on intestinal microbiota. This study shows that a disruption of the intestinal barrier in CKD promotes leakage of LPS from the gut, subsequently decreasing insulin sensitivity. Butyrate treatment improved the intestinal barrier function by increasing colonic mucin and tight junction (TJ) proteins. This modulation further ameliorated metabolic functions such as insulin intolerance and improved renal function...
