Deans' stroke musings: Expression of Basic Fibroblast Growth Factor mRNA and Protein in the Human Brain following Ischaemic Stroke

Changing stroke rehab and research worldwide now.Time is Brain! trillions and trillions of neurons that DIE each day because there are NO effective hyperacute therapies besides tPA(only 12% effective). I have 523 posts on hyperacute therapy, enough for researchers to spend decades proving them out. These are my personal ideas and blog on stroke rehabilitation and stroke research. Do not attempt any of these without checking with your medical provider. Unless you join me in agitating, when you need these therapies they won't be there.

What this blog is for:

My blog is not to help survivors recover, it is to have the 10 million yearly stroke survivors light fires underneath their doctors, stroke hospitals and stroke researchers to get stroke solved. 100% recovery. The stroke medical world is completely failing at that goal, they don't even have it as a goal. Shortly after getting out of the hospital and getting NO information on the process or protocols of stroke rehabilitation and recovery I started searching on the internet and found that no other survivor received useful information. This is an attempt to cover all stroke rehabilitation information that should be readily available to survivors so they can talk with informed knowledge to their medical staff. It lays out what needs to be done to get stroke survivors closer to 100% recovery. It's quite disgusting that this information is not available from every stroke association and doctors group.

Expression of Basic Fibroblast Growth Factor mRNA and Protein in the Human Brain following Ischaemic Stroke

Someone should be able to tell what the next steps are to use this information as a therapy protocol.

Abstract

Our previous work has demonstrated that angiogenesis occurs in the damaged brain tissue of patients surviving acute ischaemic stroke and increased microvessel density in the penumbra is associated with longer patient survival. The brain is one of the richest sources of FGF-2 and several studies have noted its angiogenic and neuroprotective effects in the nervous system. These findings led us to investigate the expression and localisation of both FGF-2 mRNA and protein in brain tissue collected within 12 h of death from 10 patients who survived for between 24 h and 43 days after acute stroke caused by thrombosis or embolus. Western blot analysis demonstrated increased FGF-2 protein expression in both grey and white matter in the infarcted core and the penumbra region compared to the normal contralateral hemisphere of all 10 patients studied. Using indirect immunoperoxidase staining of paraffin embedded sections, we observed the presence of FGF-2 in neurones, astrocytes, macrophages and endothelial cells. In situ hybridisation was used to localise and quantify mRNA expression in ischaemic brain tissue of the same 10 patients. The expression of FGF-2 in the penumbra of all patients was significantly raised compared with infarcted tissue and normal-looking contralateral hemisphere. In addition, serum FGF-2 was significantly increased between 1 and 14 days (P < 0.001) in="" many="" patients="" with="" both="" ischaemic="" stroke="">n = 28) and intra-cerebral haemorrhage (n = 16) compared with age-matched control subjects undergoing routine medical examinations (n = 20). We suggest that up-regulation of FGF-2 is one of the mechanisms that leads to angiogenesis and neuro-protection(stopping cascade of death) in the penumbra region after acute stroke in man.
