Pre‐analytical optimization of cell‐free DNA and extracellular vesicle‐derived DNA for mutation detection in liquid biopsies

Molecular Oncology, EarlyView.
Pre‐analytical handling critically determines liquid biopsy performance. This study defines practical best‐practice conditions for cell‐free DNA (cfDNA) and extracellular vesicle–derived DNA (evDNA), showing how processing time, storage conditions, tube type, and plasma input volume affect DNA integrity and mutation detection.

Deciphering transcriptional plasticity in pancreatic ductal adenocarcinoma reveals alterations in sensory neuron innervation

Molecular Oncology, EarlyView.
Pancreatic sensory neurons innervating healthy and PDAC tissue were retrogradely labeled and profiled by single‐cell RNA sequencing. Tumor‐associated innervation showed a dominant neurofilament‐positive subtype, altered mitochondrial gene signatures, and reduced non‐peptidergic neurons.

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

Journal 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

Infiltrating Ductal Carcinoma and Ductal Carcinoma in Situ Associated With Mammary Hamartoma

The Breast Journal, 2006
Mammary hamartoma is a rare nonmalignant lesion. Only 11 cases of carcinoma associated with hamartoma have been previously described in the literature. We describe a case of infiltrating ductal carcinoma (IDC) and ductal carcinoma in situ (DCIS) associated with hamartoma in a 35-year-old woman.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

Molecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

The Study of BRCA1 and BRCA2 Gene Mutations in Benign and Malignant Lesions of the Breast

Sokoto Journal of Medical Laboratory Science, 2023
Understanding the role of BRCA 1 and BRCA2 gene mutations is critical in the study of breast carcinogenesis. The aim was to study was to investigate BRCA | and BRCA2 gene mutations in benign and malignant lesions of the breast.

Fine needle aspiration cytology findings of mucinous carcinoma of breast: a study of eight cases with histological correlation

Journal of Pathology of Nepal, 2012
Background: Pure mucinous carcinoma is a rare histologic type of mammary neoplasm and may exist as mixed mucinous-ductal carcinoma. This study aims to describe fine needle aspiration cytology features of mucinous carcinoma of breast diagnosed in ...

Patient therapy outcome modeling in cancer organoids is improved by cancer‐associated fibroblasts and organoid assembly convolution

Molecular Oncology, EarlyView.
Patient‐derived organoids (PDOs) from pancreatic, colorectal, and gastric cancers were used to evaluate standard and experimental therapies. Incorporating cancer‐associated fibroblasts (CAFs) into organoid cultures improved patient therapy outcome prediction.

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

São 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.

The clinical behavior of mixed ductal/lobular carcinoma of the breast: a clinicopathologic analysis

World Journal of Surgical Oncology, 2010
Background To date, the clinical presentation and prognosis of mixed ductal/lobular mammary carcinomas has not been well studied, and little is known about the outcome of this entity. Thus, best management practices remain undetermined due to a dearth of
