Microneedle Based Sampling for Breast Cancer Tissues
نویسندگان
چکیده
We have developed a microneedle based system that is capable of extracting cell membrane lipids from real breast cancer tissues. We show that it is possible to extract phosphatidylcholine (PC) and phosphoethanolamine (PE) lipids from the cancer tissue samples with the microneedle system and analyse them with mass spectrometry (MS). PC and PE lipids act as biomarkers for breast cancer. In future such system can help surgeons in their decision making during operations or they can be used as device for tissue research at high spatial resolution.

Microfluidic sampling system for tissue analytics.
We have developed a microfluidics based sampling system for tissue analytics. The proof-of-concept of the sampling system was demonstrated by extracting lipid samples from tissue biopsies. The sample collection system consists of a disposable silicon based multiport microneedle integrated with polymer microfluidics. The polymethyl methacrylate polymer microfluidic chip has a 10 μl sample reserv...
متن کاملSNHG6 203 Transcript Could be Applied as an Auxiliary Factor for more Precise Staging of Breast Cancer
Background: Nowadays long non-coding RNAs are known as interesting functional part of the transcriptome. LncRNA SNHG6 was reported to be expressed more in breast cancer tissues than non-tumor ones. As a frequent cancer among women, breast cancer treatment needs applied biomarkers for fast prognosis and diagnosis. SNHG6 RNA and its splice variants could be considered as molecula...
متن کاملComparative Analysis of CD4+ and CD8+ T Cells in Tumor Tissues, Lymph Nodes and the Peripheral Blood from Patients with Breast Cancer
Background: CD4+ and CD8+ T cells are the main types of lymphocytes in cell-mediated immunity and play a central role in the induction of efficient immune responses against tumors. The frequencies of T cell subtypes in the peripheral blood and tumor tissues, and draining lymph nodes (dLN) can be considered as useful markers for evaluation of the immune system in cancers. Methods: In this study,...
متن کاملMolecular epidemiology of Human Papillomaviruses in breast cancer, Golestan province of Iran
Abstract Background and objectives: Breast cancer is the most prevalent one in women. Some of the common causative factors are genetic background, nutritional and environmental factors. Viruses are believed as a risk factor in this cancer, too. Recent studies reported that Human Papillomaviruses can be one of the possible risk factors of breast cancer. This study focused on investigation of the...
متن کاملCommon Raman Spectral Markers among Different Tissues for Cancer Detection
Introduction Raman spectroscopy is a vibrational spectroscopic technique, based on inelastic scattering of monochromatic light. This technique can provide valuable information about biomolecular changes, associated with neoplastic transformation. The purpose of this study was to find Raman spectral markers for distinguishing normal samples from cancerous ones in different tissues. Materials and...
