Mesothelial proliferations can be diagnostically challenging in small specimens, such as body fluid cytology and small tissue biopsies. A great morphologic challenge for pathologists is the separation of benign reactive mesothelial proliferations from malignant mesotheliomas. Reactive mesothelial proliferations may have histologic features that resemble malignancy including increased cellularity, cytologic atypia, and mitoses. Recent advances in mesothelioma genetics resulted in identification of BAP1 mutations and p16 deletions as features of malignant mesotheliomas...

Cardiac myocyte membranes contain lipids which remodel dramatically in response to heart growth and remodeling. Lipid species have both structural and functional roles. Physiological and pathological cardiac remodeling have very distinct phenotypes, and the identification of molecular differences represent avenues for therapeutic interventions. Whether the abundance of specific lipid classes is different in physiological and pathological models was largely unknown. The aim of this study was to determine whether distinct lipids are regulated in settings of physiological and pathological remodeling, and if so, whether modulation of differentially-regulated lipids could modulate heart size and function...

Cancer treatment often tends to involve direct targeting enzymes essential for the growth and proliferation of cancer cells. The aim of this study was the recognition of the possible role of selected protein kinases: PI3K, ERK1/2, and mTOR in cell proliferation and cell cycle in malignant melanoma. We investigated the role of protein kinase inhibitors: U0126 (ERK1/2), LY294002 (PI3K), rapamycin (mTOR), everolimus (mTOR), GDC-0879 (B-RAF), and CHIR-99021 (GSK3beta) in cell proliferation and expression of crucial regulatory cell cycle proteins in human melanoma cells: WM793 (VGP) and Lu1205 (metastatic)...

Enhancer of zeste homologue 2 (EZH2), a catalytic subunit of polycomb repressive complex 2, is overexpressed in a number of different tumors including breast cancer, and serves important roles in cell cycle regulation, proliferation, apoptosis, tumorigenesis and drug resistance. However, it remains unclear whether EZH2 contributes to tamoxifen resistance in breast cancer. In the present study, the role of EZH2 in tamoxifen resistance in MCF‑7 cells was investigated. EZH2 was overexpressed in MCF‑7 tamoxifen‑resistant (MCF‑7 TamR) cells...

Doxorubicin (Dox)-induced cardiotoxicity has been a well‑known phenomenon to clinicians and scientists for decades. It has been confirmed that Dox‑dependent cardiotoxicity is accompanied by cardiac cellular senescence. However, the molecular mechanisms underlying Dox cardiotoxicity remains to be fully elucidated. Long non‑coding (lnc) RNAs regulate gene transcription and the fate of post‑transcriptional mRNA, which affects a broad range of age‑associated physiological and pathological conditions, including cardiovascular disease and cellular senescence...

Consistent discrepancies in the p16/HPV-positivity have been observed in head and neck squamous cell carcinoma (HNSCC). It is therefore questionable, if all HPV+ and/or p16+ tested cancers are HPV-driven. Patients down-staged according to the HPV-dependant TNM are at risk for undertreatment and data in clinical trials may be skewed due to false patient inclusion. We performed a meta-analysis to classify clinical outcomes of the distinct subgroups with combined p16 and HPV detection. 25 out of 1677 publications fulfilled the inclusion criteria...

BACKGROUND: Screening of anal cancer in HIV-infected MSM with anal cytology results in high rates of false positive results and elevated burden of high-resolution anoscopies. High-risk HPV up-regulates p16 and Ki67 expression in epithelial cells. We assessed the usefulness of P16/Ki-67 immunostaining cytology for the diagnosis of precancerous anal lesions. METHODOLOGY: Cross-sectional multicenter study. Concomitant anal liquid cytology with p16/Ki-67 immunostaining and HRA with biopsy of acetowhite lugol-negative lesions was performed in HIV-infected MSM...

Routine testing for p16 immunohistochemistry (with selective HPV-specific test use) has been recommended for clinical practice in oropharyngeal squamous cell carcinoma (OPSCC). Data suggests that the E6H4 clone performs best for this purpose, yet no studies have evaluated the optimal antibody concentration for OPSCC testing. We evaluated three concentrations (undiluted, 1:5, and 1:10) of the primary antibody solution for E6H4 using tissue microarrays from a cohort of 199 OPSCC patients with a > 70% staining cutoff for positivity...

Mesonephric adenocarcinoma (MNAC) is a rare tumor of the female genital tract mainly occurring in the uterine cervix. To date, only a few cases of MNAC arising from of the uterine body (UB-MNAC) have been reported. The clinicopathologic and molecular characteristics of UB-MNAC remain unknown. In this study, we investigated the clinical, histopathologic, immunohistochemical, and genetic features of UB-MNAC. In total, 11 cases were included. Six patients developed metastatic disease, most commonly in lungs (5/6)...

Smoothelin is a cytoplasmic protein expressed in differentiated smooth muscle cells. Immunohistochemical evaluation of smoothelin has previously been reported in gastrointestinal (GI) smooth muscle tumors, but has yet to be studied in smooth muscle tumors of uterine and other soft tissue origin. DOG1 expression is reported to be specific for GI stromal tumors; however, variable expression has been reported in leiomyosarcomas (LMS) depending on site of origin. Overexpression of p16 is common in LMS of uterine and other sites of origin, but has not been correlated with tumor grade...

BACKGROUND: Malignant mesothelioma (MM) is a well-known malignant tumor that occurs in the pleura and is histopathologically classified into three subtypes. Lymphohistiocytoid mesothelioma (LHM) is considered a variant of epithelioid MM, and few cases have been reported. First case of LHM was reported by Henderson et al. in 1988. It is difficult to precisely diagnose LHM, and it is often misdiagnosed as reactive mesothelial cell proliferation. CASE REPORT: An 82-year-old man, with the smoking history of nine pack-years, was referred to our Department due to an abnormal shadow and pleural effusion in the left lung field on the chest X-ray imaging...
