What are some CRF1 antagonists?

Regulation of anxiety-like behavior and Crhr1 expression in the basolateral amygdala by LMO3. (27 mars 2018)
https://www.ncbi.nlm...pubmed/29609111
To examine whether Lmo3 in the amygdala is important for anxiety-like behavior, we locally reduced Lmo3 expression in the BLA of wild type mice using a lentiviral vector expressing a short hairpin RNA targeting the Lmo3 transcript. Mice with Lmo3 knockdown in the BLA exhibited decreased anxiety-like behavior relative to control mice. These results suggest that Lmo3 promotes anxiety-like behavior specifically in the BLA, possibly by altering Crhr1 expression. This study is the first to support a role for Lmo3 in anxiety-like behavior.
 

 

Go figure I have a mutation in this too together with CRHR1, CRHR1-IT1 and MGC57346-CRHR1, I wonder what else controls CRHR1. ... and what decreases LMO3? Valproic acid.

Check your plasma ammonia and urinary orotic acid.

 

Quote from a German article about urea cycle disorders (translated):

Ammonia increases the transport of tryptophan via the blood-liquor barrier, which leads to an increased production and liberation of serotonin - a tryptophan restriction has proven favorable in patients with constat moderate hyperammonemia.

Hoffmann, Georg F. et al.: 2004

Without diagnosis you could try to take sodium benzoate, it reduces ammonia in an alternative pathway.

valproic acid (XR) the only thing that worked..

possibly olanzapine and lithium carbonate too

 

antipsychotic, anticonvulsant and benzo etc more likely to work since they hit a broad spectrum in the brain .

either too much CRHR1 mutation in the hippocampus

or somewhere in the amygdala too much CRHR by the gene LMO3 in the basal amygdala

or..something with these two CRHR1-IT1 (CRHR1 intronic transcript 1) & MGC57346-CRHR1 etc

(EXCESS CRHR1 AMYGDALA-HIPPOCAMPUS)
 
With an acoustic stimulus, for example, the circulation runs from the ears into the limbic system, which is located between the cerebral cortex and the brain stem.
There, in the amygdala, known as the almond core, anxiety and fear are activated in tiny fractions of a second by the stimulus of unconscious and imperceptible, fast as light flash-thoughts.The almond core, consisting of a small almond-shaped accumulation of neurons, has the characteristic and ability to put the entire organism of the human being into a highly sensitive alert-state and to cause a tension of anxiety or fear. The almond core cooperates with another factor of the nearby brain centre, namely the hippocampus, in which memories, living-experiences, situations and experiences are stored like in an archive. These are with the speed of light compared with the current threat or actually with what is regarded as an acute threat.. However, the whole process is not consciously perceived by the human being, because the conscious realisation of the anxiety or the fear only manifests itself once hormonal signals emanating from the almond core trigger the anxiety reaction or fear reaction like a torrent.
 Put in different words, the following happens: 
 The almond core sends the instruction i.e. impulse to the hypothalamus to release the corticotropin-releasing hormone.
This hormone, called CRH for short, causes the stimulation of the pituitary gland as well as the adrenal glands, through which they otherwise release adrenaline as well as noradrenaline and cortisol. But these are not the only processes, because there are several other hormonal factors at play during the whole exercise, although it would go too far to explain them.
But what ultimately results from everything is that the gastric blood vessels constrict, and the digestive processes cease, the heart begins to race, whereby the blood circulation is stimulated.
In addition, a bristling up of the hair takes place; the blood pressure rises, which increases alertness and readiness for action.
The breathing becomes faster, whereby the body can act better, because it gets more oxygen.
 Anxiety sweat, and sweaty hands are further consequences, because the blood flow to the skin is reduced in order to supply the muscles as well as the arms and legs with more blood. The liver provides a high plus in energy by ensuring that more sugar gets into the blood. Long term of this will cause the body to break down. Study request: Take 10 rats with normal CRHR1 in the hippocampus and amygdala and 2 rats with EXCESS or perhaps low levels, this will cause the ones with abnormals levels great deal of stress... BUT , take 10 rats with normal CRHR1 and 10 other rats with high CRHR1 and have them live together, in my theory nothing will happen because it is a social structure thing and there will be other rats with this excess CRHR1. Too little CRHR1 cant overcome fear via the PFC.too much CRHR1 = BAD. Because most people in society have normal levels so you'd have to have normal levels also to fit in for lack of better words. And the human body works best in a balanced way.

Allostatic load is "the wear and tear on the body" which accumulates as an individual is exposed to repeated or chronic stress. The term was coined by McEwen and Stellar in 1993. It represents the physiological consequences of chronic exposure to fluctuating or heightened neural or neuroendocrineresponse which results from repeated or prolonged chronic stress.

amygdala, locus coeruleus  (not issue) and hippocampus. Within the hippocampus, the CRHR1s are most abundant, residing mainly on the pyramidal cells of CA1 and CA3. Chronic activation of CRHR1s by CRH induced by early life stress has been shown to underlie memory deficits and learning impairments and anxiety in adulthood.

 

In CRF1 knockout mice, and mice treated with a CRF1 antagonist, there is a decrease in anxious behavior and a blunted stress response, suggesting that CRF1 mechanisms are anxiogenic.[8][12] However, the effect of CRF1appears to be regionally specific and cell-type specific, likely due to the wide variety of cascades and signaling pathways activated by the binding of CRF or CRF-agonists.[12] In the central nervous system, CRF1 activation mediates fear learning and consolidationin the extended amygdala, stress-related modulation of memory formation in the hippocampus, and brainstem regulation of arousal.[12]

Antidepressant-Like Effects of Shuyusan in Rats Exposed to Chronic Stress: Effects on Hypothalamic-Pituitary-Adrenal Function

Results from the present study demonstrated that Shuyusan could decrease the serum contents of CRH, ACTH, and CORT. It also could increase the expression of hippocampus GR receptor in the rat model of depression. Our results suggested that the mechanisms of action of Shuyusan were due to decreasing the serum contents level of CRH, ACTH, and CORT and increasing the expression of hippocampus GR receptor. Fluoxetine is selective serotonin reuptake inhibitors’ (SSRIs) medications, it could increase the levels of NE, 5-HT, and DA in the brain of rat and was related to downregulation of 5-HT receptor, but not decreased the serum contents level of CRH, ACTH, and CORT and increased the expression of hippocampus GR receptor.

Drugs such as sumatriptan induce a significant decrease of ACTH, cortisol, and prolactin concentrations, both in patients with migraine and in controls (Rainero et al., 2001). Acute subcutaneous administration of sumatriptan activates the pituitary-adrenal axis: significant increases in β-endorphin and cortisol concentrations are reported across all subjects receiving sumatriptan (Facchinetti et al., 1994), and these would produce secondary effects.

Guys. it is said that twins share identical genes. but lets say twins are born and one is born with high levels of LMO3 (leading too excess lvls of crhr1) and the other has low level of LMO3(low levels of crhr1). Neither one has normal levels. Would this disprove that fact? Because i'm pretty sure I know of one and they are on youtube HodgeTwins. 

One is also left handed and the other is right handed. This could also mean handedness is part genetic.

 

 

It is true that identical twins share their DNA code with each other. This is because identical twins were formed from the exact same sperm and egg from their father and mother. ... While this rarely happens, it makes it so that one identical twin may have a genetic condition, while the other twin does not.

if twins have identical genes then why do they get different dna origin results

CRF1 acts through a heteromer with Vasopressin-1B, and it's actually V1b that has been shown to be upregulated most over time (and fails to respond to negative feedback by cortisol). We're doing a group-buy of a Vasopressin-1B antagonist right now, sign-ups open for this week. I can't post links yet so message me for the Discord server link where it's being organised.

Man great thread with a lot of follow up @

kurdishfella

 

Do you still take any?

 

I've been looking for the mechanism for restoring proper restorative sleep after a decade without it, with excessive REM sleep & fast onset.

and I found lowering CRH is a major mechanism for this

 

In depression / narcolepsy REM sleep latency shortens dramatically. REM sleep goes up and Slow Wave Sleep goes down. So people get exhausting overactive sleep with crazy dreaming. which further feeds into the disorder.

 

Well if people (without addisons) take hydrocortisone before sleep it significantly delays REM latency , lowers REM sleep, and increases slow wave sleep.

but the theory is its not the cortisol itself. its the flood dose of cortisol creating a drop in Corticotropic Releasing Hormone as a response. where CRH acts as a signalling hormone for REM sleep

https://www.nature.c...ticles/1300362 

Cortisol administration resulted in a significant increase in highly synchronized EEG activity including delta and theta frequencies, according to a higher amount of slow-wave sleep. This effect predominated in the first few hours of night sleep. REM sleep was decreased, which appeared to be secondary to the lengthened first sleep cycle 

&
https://pubmed.ncbi....ih.gov/7829766/
https://pubmed.ncbi....h.gov/3614616/ 
https://pubmed.ncbi....h.gov/1996621/ 

* "demonstrating that some cortisol is needed for REM sleep, with excess cortisol inhibiting REM sleep." "An alternative interpretation is that the decrease in REM sleep in normal subjects receiving exogenous glucocorticoids is caused by CRH and/or ACTH suppression"    "In Addison’s patients, on the other hand, high ACTH and CRH levels are still present despite HC administration, so that CRH and/or ACTH may still signal the entry into REM sleep"  "Although one study found that iv administration of CRH reduced REM sleep (23), this is probably an indirect effect of CRH, as iv administration of this hormone is unlikely to cross the blood-brain barrier."     


 

a lot of these CRH lowering substances with significant effect are inaccessable to me unfortunately. but i have 2 leads to add to this thread and 1 with big effect

 

1. iron deficiency also comes with the REM sleep skew (even in iron deficiency without anemia). and in iron deficiency there's a lower cortisol release response from ACTH. which gets stimulated by CRH. so i guess CRH stays high to try make up for the lower response? creating the rem sleep skew.  so fixing with heme iron may play a role in lowering it.

 

https://pubmed.ncbi....ih.gov/1651678/

https://www.ncbi.nlm...s/PMC3424605/  

https://jcsm.aasm.or...664/jcsm.9690  

 

2. high salt diet for 9 days had a big impact in mice here, if the same applies to humans https://pubmed.ncbi....ih.gov/8247254/ (but maybe not in the few hours leading to sleep , just overall intake for 9 days?)
" CRH mRNA levels were unchanged after 2 days salt-loading, but declined to 77% of control levels after 9 days"
which is interesting because you mentioned lithium, which is known to raise slow wave sleep and delay REM onset. and lithium has similar properties to sodium.

Not sure what amount they used here
