her2 protein – her2 positive cancer survival rate

 · The HER2 gene makes HER2 proteins also sometimes referred to as HER2/neu proteins HER2 proteins are receptors on breast cells Normally HER2 receptors help control how a healthy breast cell grows divides, and repairs itself, But in about 10% to 20% of breast cancers, the

Her2/ERBB2 Protein Overview: Sequence Structure Function

Breast Cancer HER2 Status

HER2/neu

HER2 is a growth-promoting protein on the outside of all breast cells, Breast cancer cells with higher than normal levels of HER2 are called HER2-positive , These cancers tend to grow and spread faster than other breast cancers, but are much more likely to respond to treatment with drugs that target the HER2 protein ,

What Is HER2/neu and What Does It Mean?HER2/neu often just shortened to HER2 is a growth-promoting protein on the outside of all breast cells, Breast cancer cells with higher than normHow Are Breast Tumors Tested For HER2?A biopsy or surgery sample of the cancer is usually tested with either immunohistochemical stains IHC or Fluorescent in situ hybridization FISHWhat Do The Test Results Mean?The results of HER2 testing will guide you and your cancer care team in making the best treatment decisions,Many breast cancer specialists think th

Significance of HER2 protein expression and HER2 gene

HER2gene status was significantly associated with distant tumor metastasis and stage P= 0028 and 0,025 HER2 protein overexpression as measured by IHC or HER2gene amplification as measured by FISH was not associated with overall survival OS or disease-specific survival for the overall group of 1058 patients

HER2, ou HER2/neu, signifie human epidermal growth factor receptor 2, c’est-à-dire récepteur 2 du facteur de croissance épidermique humain, Le travail du HER2 est de contrôler une protéine située à la surface des cellules qui les aide à croître, Si le gène HER2 change, cela risque de favoriser la croissance d’une tumeur,

Cancer du sein : Le statut HER2

HER2 est une protéine naturellement présente dans l’organisme, Il s’agit d’un récepteur transmembranaire impliqué dans la régulation de la prolifération cellulaire, Quand une cellule devient cancéreuse, il peut arriver que le nombre de récepteurs HER2 présents à sa surface augmente anormalement, Cette augmentation favorise la croissance des cellules cancéreuses, On dit alors que ces cellules « surexprimen…

Analyse du statut HER2

Ce sont des cancers particulièrement agressifs en raison de l’action d’HER2 qui déclenche des voies de développement des cellules cancéreuses Les cellules cancéreuses sont plus susceptibles de se propager dans les ganglions lymphatiques ou à d’autres organes majeurs du corps Le principe d’action du traitement standard actuel Herceptin trastuzumab est de se lier à des récepteurs de HER2 pour bloquer les effets de la protéine HER2…

Her2/ERBB2 Protein Overview The oncogene originally called NEU was derived from rat neuro/glioblastoma cell lines Yang-Feng et al, 1985 It encodes a tumor antigen p185, which is serologically related to EGFR, the epidermal growth factor receptor 131550,Coussens et al, 1985 identified a potential cell surface receptor of …

Antibody-PROTAC Conjugates Enable HER2-Dependent Targeted

 · The HER2 receptor is a 1255 amino acid 185 kD transmembrane glycoprotein located at the long arm of human chromosome 17 17q12 [6] HER2 is expressed in many tissues and its major role in these tissues is to facilitate excessive/uncontrolled cell growth and tumorigenesis [7–9] 2 Function,

We show that 3 selectively targets bromodomain-containing protein 4 BRD4 for degradation only in HER2 positive breast cancer cell lines while sparing HER2 negative cells Using live cell confocal microscopy we show internalization and lysosomal trafficking of the conjugate specifically in HER2 positive cells, leading to the release of active PROTAC in quantities sufficient to induce potent BRD4 degradation, These studies …
