Intraductal Papillary Neoplasm of Bile Duct: Updated Clinicopathological Characteristics and Molecular and Genetic Alterations

open access: yesJournal of Clinical Medicine, 2020
Intraductal papillary neoplasm of the bile duct (IPNB), a pre-invasive neoplasm of the bile duct, is being established pathologically as a precursor lesion of invasive cholangiocarcinoma (CCA), and at the time of surgical resection, approximately half of

Phosphatidylinositol 4‐kinase as a target of pathogens—friend or foe?

open access: yesFEBS Letters, EarlyView.
This graphical summary illustrates the roles of phosphatidylinositol 4‐kinases (PI4Ks). PI4Ks regulate key cellular processes and can be hijacked by pathogens, such as viruses, bacteria and parasites, to support their intracellular replication. Their dual role as essential host enzymes and pathogen cofactors makes them promising drug targets.

Carcinoma Cuniculatum with Bone Invasion Mimicking a Viral Wart

open access: yesRevista da Sociedade Portuguesa de Dermatologia e Venereologia, 2021
Carcinoma cuniculatum is a rare variant of low-grade and well-differentiated squamous cell carcinoma. It is a locally invasive tumor, although it has low metastatic potential. It was originally described in the plantar region but may exceptionally appear

The role of histone modifications in transcription regulation upon DNA damage

open access: yesFEBS Letters, EarlyView.
This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

Matrix metalloproteinases in the process of invasion and metastasis of breast cancer [PDF]

open access: yesArchive of Oncology, 2006
Metastatic cascade in malignant tumors, including breast cancer, starts with localized invasion of the host tissue. This process, requiring that tumor cells separate from each other, includes loss of homotypic and heterotypic cell adhesion and cell-cell ...

Mechanisms of parasite‐mediated disruption of brain vessels

open access: yesFEBS Letters, EarlyView.
Parasites can affect the blood vessels of the brain, often causing serious neurological problems. This review explains how different parasites interact with and disrupt these vessels, what this means for brain health, and why these processes matter. Understanding these mechanisms may help us develop better ways to prevent or treat brain infections in ...

The newfound relationship between extrachromosomal DNAs and excised signal circles

open access: yesFEBS Letters, EarlyView.
Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Extensive Intramedullary Spread of Oral Squamous Cell Carcinoma with Minimal Intraoral Manifestation: A Case Report

open access: yesJournal of Clinical and Diagnostic Research
Globally, Oral Squamous Cell Carcinoma (OSCC) is a significant public health problem, especially in developing countries, where delayed diagnosis often leads to advanced-stage presentation and poor outcomes. OSCC typically presents with visible intraoral

Specific features of proliferation and apoptosis in non-invasive adenocarcinoma of endometrium and adenocarcinoma with invasion into myometrium

open access: yesPatologìâ, 2014
Introduction. The development of tumors occurs as a multistage process, where each step corresponds to certain genetic changes of cells and it is a reflection characteristic of different histological forms of cancer. This usually multiple changes include
