Expression of immune checkpoint regulators, cytotoxic T lymphocyte antigen 4 (CTLA-4) and programmed death-ligand 1 (PD-L1), in female breast carcinomas. [PDF]

open access: yesPLoS ONE, 2018
Immune checkpoint regulators, cytotoxic T lymphocyte antigen 4 (CTLA-4) and the programmed cell death protein-1/programmed death-ligand 1 (PD-1/PD-L1) have emerged as promising new targets for cancer therapeutics. While tumor expression of PD-L1 has been

Importance of microcalcifications in mammographic differentiation of the invasive ductal breast cancer and of the ductal carcinoma in situ [PDF]

open access: yesMedicinski Podmladak, 2017
Introduction: Microcalcifications represent a significant and reliable sign of the presence of the malignant breast lesion. Aim: The aim of the paper is to radiologically evaluate the type and distribution of suspicious microcalcifications, in patients ...

Infiltrating ductal carcinoma breast with central necrosis closely mimicking ductal carcinoma in situ (comedo type): a case series

open access: yesJournal of Medical Case Reports, 2007
Here we present a series of infiltrative ductal carcinoma breast cases (infiltrative ductal carcinoma with central necrosis) so closely mimicking 'DCIS with central comedo necrosis' that on initial morphological analysis these foci of tumors were labeled

Malignant progression of liver cancer progenitors requires lysine acetyltransferase 7–acetylated and cytoplasm‐translocated G protein GαS

open access: yesHepatology, EarlyView., 2022
KAT7‐acetylated and cytoplasm‐translocated G‐protein GαS enhances IL‐6 effect and drives HCC progenitor cell progression. Abstract Background and Aims Hepatocarcinogenesis goes through HCC progenitor cells (HcPCs) to fully established HCC, and the mechanisms driving the development of HcPCs are still largely unknown.

Protein expression of c-erbB-2 and p53 in normal ducts, ductal carcinoma in situ and invasive carcinoma of the same breast

open access: yesSão Paulo Medical Journal
CONTEXT AND OBJECTIVE: Breast cancer is thought to derive from progressively aberrant, non-invasive breast lesions, but it is not known exactly how invasive breast cancer develops from these lesions.

Multiomics identifies the link between intratumor steatosis and the exhausted tumor immune microenvironment in hepatocellular carcinoma

open access: yesHepatology, EarlyView., 2022
Steatotic HCC can be diagnosed by MRI and forms a pro‐tumor immune microenvironment with high expression of PD‐L1, M2 polarization of macrophages and activation of CAFs, which may be a good target for combined immunotherapy. Abstract Background and Aims Immunotherapy has become the standard‐of‐care treatment for hepatocellular carcinoma (HCC), but its ...

Neuroendocrine Carcinoma of the Breast – Real versus Mimic [PDF]

open access: yesJournal of Krishna Institute of Medical Sciences University, 2016
Primary neuroendocrine carcinoma of the breast is a rare entity and is difcult to differentiate from invasive ductal carcinoma with neuroendocrine differentiation especially on small core biopsy specimens.

The NADPH oxidase NOX4 regulates redox and metabolic homeostasis preventing HCC progression

open access: yesHepatology, EarlyView., 2022
Loss of NOX4 in HCC tumor cells induces metabolic reprogramming in a Nrf2/MYC‐dependent manner to promote HCC progression. Abstract Background and Aims The NADPH oxidase NOX4 plays a tumor‐suppressor function in HCC. Silencing NOX4 confers higher proliferative and migratory capacity to HCC cells and increases their in vivo tumorigenic potential in ...

An Unusual Presentation of Extensive Ductal Carcinoma in Situ Accompanying Invasive Ductal Carcinoma on MRI: A Case Report

open access: yes대한영상의학회지, 2022
The incidence of ductal carcinoma in situ has increased with the rise in screening mammography; currently, ductal carcinoma in situ constitutes 20%–25% of all breast cancers, and up to half of them may become invasive.
