SHBG IR insulin resistance insulin Estrogen Estradiol obesity hormone hormones

shared by Nathan Goodyear on 02 Mar 15 - No Cached
  • Nathan Goodyear on 02 Mar 15
     
    Elevated insulin levels in men is associated with decreased liver production of SHBG and thus reduced SHBG levels.  Obesity is associated with decreased urinary cortisol in this study.  The authors found the low cortisol also contributed to the low SHBG as well. Low SHBG is associated with puberty, obesity, IR, hypothyroidism, and during androgen therapy.  SHBG is increased as a result of aging, short-term fasting, Estrogen, hyperthyroid, and liver disease.

    Animal study from '09 found that COX2 inhibitor blunted LPS decrease in testes weight, decrease in testicular interstitial fluid, and serum Testosterone.  The point here is that LPS, in this animal model, decreased gonadal weight and Testosterone production and the anti inflammatory, COX2, blunted that effect.

LPS lipopolysaccharides Alzheimer's disease brain inflammation

shared by Nathan Goodyear on 23 Sep 17 - No Cached
  • lipopolysaccharides (LPS), either alone or in combination, have indicated that when compared, bacterial LPSs exhibit the strongest induction of pro-inflammatory signaling in human neuronal–glial cells in primary coculture of any single inducer, and different LPS extracts from different gastrointestinal (GI)-tract resident Gram-negative bacteria appeared to have different pro-inflammatory potential
  • powerful inducer of the NF-κB
  • In both neocortex and hippocampus, LPS has been detected to range from a ~7- to ~21-fold increase abundance in AD brain
  • ...15 more annotations...
  • Major Gram-negative bacilli of the human GI-tract, such as the abundant B. fragilis and Escherichia coli (E. coli), are capable of discharging a remarkably complex assortment of pro-inflammatory neurotoxins
  • (i) bacterial amyloids (10, 21); (ii) endotoxins and exotoxins (5, 12); (iii) LPS (12, 18); and (iv) small non-coding RNAs (sncRNAs)
  • integral components of the outer leaflet of the outer membrane of Gram-negative bacteria, LPS
  • LPS, the major molecular component of the outer membrane of Gram-negative bacteria normally serves as a physical barrier providing the bacteria protection from its surroundings
  • LPS is also recognized by the immune system as a marker for the detection of bacterial pathogen invasion and responsible for the development of inflammatory response is perhaps the most potent stimulator and trigger of inflammation known
  • AD-affected brains have remarkably large loads of bacterial-derived toxins compared to controls. The transfer of noxious, pro-inflammatory molecules from the GI-tract microbiome to the CNS may be increasingly important during the course of aging when both the GI-tract and blood–brain barriers become significantly more permeable
  • first evidence of a perinuclear association of LPS with AD brain cell nuclei
  • LPS-mediated stimulation of chronic inflammation, beta-amyloid accumulation, and episodic memory decline in murine models of AD (39, 40) and a biophysical association of LPS with amyloid deposits and blood vessels in human AD patients
  • Strong adherence of LPS to the nuclear periphery has recently been shown to inhibit nuclear maturation and function that may impair or block export of mRNA signals from brain cell nuclei, a highly active organelle with extremely high rates of transcription, mRNA processing, and export into the cytoplasm
  • LPS may be further injurious to the nuclear membrane just as LPS contributes to cerebrovascular endothelial cell membrane injury
  • high intake of dietary fiber is a strong inhibitor of B. fragilis abundance and proliferation in the intact human GI-tract and as such is a potent inhibitor of the neurotoxic B. fragilis-derived amyloids, LPS, enterotoxins, and sncRNAs.
  • GI-tract microbiome-derived LPS may be an important initiator and/or significant contributor to inflammatory degeneration in the AD CNS
  • LPS has been recently localized to the same anatomical regions involved in AD-type neuropathology
  • a known pro-inflammatory transcription factor complex that triggers the expression of pathogenic pathways involved in neurodegenerative inflammation
  • pro-inflammatory amyloids, endo- and exotoxins, LPSs, and sncRNAs but also serve as potent sources of membrane-disrupting agents

  • MicroRNAs (miRNAs), a major family of small RNAs, are ∼23 nt-long single strands of RNA that bind to mRNA transcripts to inhibit their translation
  • A recent study by Zhang et al. reported that plant-derived miRNAs can be found in human serum.
  • The group demonstrates that the plant miRNA miR168 may be taken up through dietary intake to inhibit the expression of its target low-density lipoprotein receptor 1 in the liver21, providing the first evidence that miRNA in food may influence gene expression in mammalian organs.
  • ...6 more annotations...
  • A more recent finding by the same group shows that a plant miRNA from honeysuckle is able to inhibit Influenza A replication22, indicating that plant miRNAs may be useful for treating human diseases.
  • We found that plant miR159 could be detected in human sera and its levels were inversely correlated with BC incidence and progression.
  • We further identified TCF7 as a mammalian target for miR159 and showed the anti-proliferative function of miR159 in BC cells using in vitro and in vivo models, demonstrating for the first time that a plant miRNA is able to influence BC cell growth.
  • certain dietary miRNAs from plants and other species may serve as highly affordable and powerful means of treatment with minimal inconvenience to patients.
  • miR159 which (using a synthetic mimic) targets TCF7 to inhibit the proliferation of cells whose growth is dependent on TCF7 such as the BC cells MDA-MB-231
  • our study using a BC model clearly indicates the anti-tumor effect of orally administered synthetic miR159 in its naturally existing form with the plant-specific 2'-O-methylation, suggesting the feasibility of using synthetic forms of plant miRNAs as dietary supplements in the treatment of human cancers, including those outside of the GI track

  • In the course of different disease states, the levels of T3, T4, and TSH decrease
  • euthyroid sick syndrome

  • proportionally associated with disease severity and survival
  • nonthyroidal illness syndrome
  • Patients with persistent deterioration of hormone levels (T3, T4) during the study period had higher mortality than those who normalized the function of the thyroid axis
  • LT3S in patients with septic shock is part of the pathophysiology of this disease and/or an associated organ (endocrine-metabolic) failure and not just an adaptive phenomenon
  • substitution treatment with synthetic thyroid hormones could modify the hemodynamic symptoms of septic patients, contributing in part to the decrease in their morbidity and mortality
