Ebbe Boedtkjer The acidic tumor microenvironment modifies malignant cell behavior. Here, we study consequences of the microenvironment in breast carcinomas. Beginning at carcinogen-based breast cancer induction, we supply either regular or NaHCO3-containing drinking water to female C57BL/6j mice. We evaluate urine and blood acid-base status, tumor metabolism (microdialysis sampling), and tumor pH (pH-sensitive microelectrodes) in vivo. Based on freshly isolated epithelial organoids from breast carcinomas and normal breast tissue, we assess protein expression (immunoblotting, mass spectrometry), intracellular pH (fluo...

Authors: Roşu GA, Furău GO, Ionescu CA, Dimitriu MCT, Neacşu A, Ioan RG, Călin FD, Matei A, Bănacu M, Popescu I, Gheorghiu D, Neacşu I, Bacalbaşa N, Furău CG Abstract Epithelial ovarian carcinoma makes up 90-95% of all ovarian malignancies, taking into account also low-malignant-potential tumors. The Krukenberg tumor is a rare metastatic adenocarcinoma (ADK) in the ovary, representing 1-2% of ovarian tumors. Multiple primary malignant neoplasms may exist when more than one cancerous tumor is diagnosed in the same or a different organ. The incidence of multiple primary cancers among malignancies is between 2...

Authors: Dochiţ CM, Stepan AE, Mărgăritescu C, Florescu MM, Simionescu CE Abstract Alteration of cadherin immunophenotype is associated with the epithelial-mesenchymal transition, a complex biomolecular mechanism involved in carcinomas progression. The study investigated the immunoexpression of E-, P- and N-cadherins in 50 serous malignant tumors of ovary related to the histopathological prognostic parameters of the lesions, using a quantification based on scores that took into account the number of marked cells and the intensity of the reactions. The E-cadherin and P-cadherin immunostainings were significantly ...

AbstractIt has been established that ZFP36 (also known as Tristetraprolin or TTP) promotes mRNA degradation of proteins involved in inflammation, proliferation and tumor invasiveness. In mammary epithelial cellsZFP36 expression is induced by STAT5 activation during lactogenesis, while in breast cancerZFP36 expression is associated with lower grade and better prognosis. Here, we show that the AP-1 transcription factor components, i.e.JUN, JUNB, FOS, FOSB, in addition toDUSP1, EGR1, NR4A1,IER2 andBTG2, behave as a conserved co-regulated group of genes whose expression is associated toZFP36 in cancer cells. In fact, a signifi...

Conclusions: The current study is the first to investigate the use of established scoring criteria for PD-L1 expression in malignant salivary gland tumors. Our findings identify unique characteristics for AC, NOS among the family of SGCs, as it is associated with poor prognosis and might represent a valuable target for immune checkpoint inhibition.

Conclusion: This patient lacked conventional SG acinar cells following anti-PD-L1 therapy and demonstrated presence of hybrid intercalated duct-like structures. Understanding which mechanisms and dynamics underpinning this aberrant parenchyma may be crucial to understand how SG dysfunction post ICI therapy, and potentially other affected organs. Furthermore, although the patient treated with anti-PD-L1 antibody examined here fulfills the criteria for pSS and demonstrated focal lymphocytic sialadentitis, the further histopathological characteristics do not resemble pSS.

AbstractEsophageal squamous cell carcinoma is the most predominant malignancy of the esophagus. Its histological precursors (dysplasia) emerge in the esophageal epithelium that their progression into the underlying layers leads to cancer. The epithelium is the origin of many solid cancers and, accordingly, the focus of numerous computational models. In this work, we proposed a framework to establish a two-dimensional, globally coupled map to model the epithelium dynamics. The model aims at diagnosing the early stage of dysplasia based on microscopic images of endoscopic biopsies. We used the logistic map as a black-box mod...
