  • the oral bioavailability of DCA is nearly 100%
  • the oral bioavailability of DCA is almost 100%.
  • DCA can penetrate into the traditional chemotherapy sanctuary sites. Interestingly, it was reported that DCA could penetrate across the BBB,30 exhibiting the potential activity for brain therapy.
  • ...23 more annotations...
  • Clinical studies of DCA have shown reduced lactate levels
  • It has been reported that DCA activates the PDH by inhibition of PDK in a dose-dependent manner, and results in increased delivery of pyruvate into the mitochondria
  • The antitumor activity of DCA on nonsmall cell lung cancer, breast cancer, glioblastomas, and endometrial and prostate cancer cells has been demonstrated
  • It is well known that many chemotherapeutic agents have a low therapeutic index in brain tumors.
  • The most common metabolic hallmark of cancer cells is their propensity to metabolize glucose to lactic acid at a high rate even in the presence of oxygen
  • Pyruvate dehydrogenase kinase (PDK) is a gate-keeping enzyme that regulates the flux of carbohydrates (pyruvate) into the mitochondria
  • In the presence of activated PDK, pyruvate dehydrogenase (PDH), a critical enzyme that converts pyruvate to acetyl-CoA instead of lactate in glycolysis, is inhibited, limiting the entry of pyruvate into the mitochondria.
  • the level of Hsp70 was significantly decreased
  • DCA can penetrate the BBB
  • It has been reported that DCA treatment resulted in an increase in the proportion of tumor cells in the S phase, showing a decrease in proliferation as well as the induction of apoptosis
  • Heat shock proteins (HSPs) are involved in protein folding, aggregation, transport, and/or stabilization by acting as a molecular chaperone, leading to the inhibition of apoptosis by both caspase-dependent and/or independent pathways
  • HSPs are overexpressed in a wide range of human cancers and are implicated in tumor cell proliferation, differentiation, invasion, and metastasis
  • Considering the fact that high expression of HSPs is essential for cancer survival, the inhibition of HSPs is an important strategy of anticancer therapy.
  • In addition, after 5 years of continued treatment with oral DCA at a dose of 25 mg/kg, the serum DCA levels are only slightly increased compared with the levels after the first several doses, also showing its safety for oral administration at this dose.
  • DCA can enter the circulation rapidly after oral administration and then generate the stimulation of PDH activity generally within minutes.
  • Our in vivo results in tumor tissues indicated that DCA significantly induced ROS production and decreased MMP in tumor tissues
  • The numbers of microvessels in the DCA treatment groups were significantly decreased, suggesting the potential antiangiogenic effect of DCA
  • Under hypoxic conditions, hypoxia-inducible factor (HIF-1α) is activated and induces angiogenesis
  • In addition, HIF-1α can also induce the expression of PDK,48 which can inhibit the activity of PDH
  • The inhibition effect of DCA on HIF-1α would decrease vascular endothelial growth factor and inhibit angiogenesis
  • the antiangiogenic effect in the 25 mg/kg treatment group was lower than that in 75 mg/kg or 125 mg/kg treatment groups
  • In conclusion, DCA induces the apoptosis of C6 cells through the activation of the mitochondrial pathway, arresting the cell cycle of C6 cells in S phase and down-regulating Hsp70 expression.
  • DCA significantly induced the ROS production and decreased the MMP in tumor tissues. Our in vivo antitumor activity results also indicated that DCA has an antiangiogenic effect

  • LR solution has an average pH of 6.5, is hypo-osmolar (272 mOsm/L), and has similar electrolytes (130 mM Na+, 109 mM Cl-, 28 mM lactate, etc.) to plasma
  • hyperchloremic acidosis
  • ...26 more annotations...
  • LR’s acid base balance is superior to that of NS’s
  • There were no significant differences between LR and NS groups in fibrinogen concentrations or platelet count
  • Total protein dropped
  • no significant differences in Hct (Table  1) or total protein between LR and NS groups
  • Bicarbonate HCO3- levels were decreased by hemorrhage but returned to pre-hemorrhage values by 3 h after LR resuscitation, whereas no return was observed with NS resuscitation
  • Na+ was increased after NS resuscitation
  • No changes in Na+ or K+ were observed
  • K+ did not change initially after NS resuscitation but was elevated at 6 h afterwards
  • Ca++ was similarly decreased
  • Cl- was elevated for 6 h after NS resuscitation, with no changes shown after LR resuscitation
  • PT was similarly prolonged by resuscitation with LR (from 11.2 ± 0.2 sec at baseline to 12.1 ± 0.2 sec at 6 h) and NS
  • Plasma aPTT was also similarly prolonged by resuscitation with LR (from 17.1 ± 0.5 sec baseline to 20.1 ± 1.2 sec at 6 h) or NS
  • NS resuscitation resulted in better oxygen delivery and oxygen delivery-to-oxygen demand ratio as an index of oxygen debt
  • NS had better tissue perfusion and oxygen metabolism than LR
  • LR resuscitation returned BE and bicarbonate to pre-hemorrhage levels within 3 h, but no return of BE or bicarbonate was observed for 6 hr with NS resuscitation
  • current blood bank guidelines state that LR should not be mixed with blood to prevent the risk of clot formation from calcium included in LR
  • LR resuscitation should not be given with blood through the same iv-line and crystalloids should be avoided in patients with blood transfusion
  • PT and aPTT were prolonged for 6 h after hemorrhage and resuscitation, suggesting a hypocoagulable states
  • potential thrombotic risk from LR resuscitation is unlikely.
  • we suspected that the blood pressure after NS resuscitation would be lower than that of LR due to its vasodilator effects
  • NS required a larger resuscitation volume and was associated with poor acid base status and elevated serum potassium in this model
  • NS required 50% more volume and was associated with a higher cardiac output and lower peripheral resistance, as compared to LR resuscitation
  • These differences are possibly due to the vasodilator effects from NS
  • an elevation of K+ was observed at 6 h post NS resuscitation, while no change of K+ was observed after LR resuscitation
  • The mechanism for the increase of K+ from NS is not fully known
  • NS is associated with vasodilator effects and the risks of metabolic acidosis and hyperkalemia

  • Hyperthermia differs fundamentally from fever in that it elevates the core body temperature without changing the physiological set point
  • hyperthermia is induced by increasing the heat load and/or inactivating heat dissipation
  • mor cells [2]. Although significant cell killing could be achieved by heating cells or tissues to temperatures > 42°C for 1 or more hours, the application, measurement and consistency of this temperature range within the setting of cancer clinical trials

  • Hsps are a family of stress-induced proteins
  • they are key regulators of cellular protein activity, turnover and trafficking
  • Hsps ensure appropriate post-translational protein folding, and are able to refold denatured proteins, or mark irreversibly damaged proteins for destruction
  • the ability of fever-range hyperthermia to induce reactive immunity against tumor antigens through DCs and NK-cells is likely mediated by Hsps
  • thermotolerance
  • Hsps support the malignant phenotype of cancer cells by not only affecting the cells’ survival, but also participating in angiogenesis, invasion, metastasis and immortalization mechanisms
  • Hsps released from stressed or dying cells activate dendritic cells (DCs), transforming them into mature APCs
  • In theory, fever-range hyperthermia may take advantage of tumor cell Hsps by inducing their release from tumor cells and augmenting DC priming against tumor antigens
  • In several models of hyperthermia, heat-treated tumors exhibited improved DC priming and generation of systemic immunity to tumor cell
  • hyperthermia alone can enhance antigen display by tumor cells, thus rendering them even more susceptible to programmed immune clearance
  • Fever-range hyperthermia may also induce Hsps
  • Hsps may exert an adjuvant effect by bolstering MHC class II and co-stimulatory molecule expression by DCs
  • thermal ablation of liver tumors in particular has demonstrated an ability to potentiate immune responses [57, 58] and elicit robust T-cell infiltrates at ablation sites
  • specific Hsp, Hsp70, directly inhibits apoptosis pathways in cancer cells, as demonstrated in human pancreatic, prostate and gastric cancer cells
  • Cross-priming is the ability of extracellular Hsps complexed to tumor peptides to be internalized and presented in the context of MHC class I molecules on APCs, thus allowing potent priming of CTLs against tumor antigens
  • It has been reported that Hsps are generated from necrotic tumor cell lysates, but not from tumor cells undergoing apoptosis
  • tumor cells exposed to hyperthermia in the heat shock range (42°C for 4h) prior to lysing, DC activation and cross-priming were significantly enhanced with the application of heat
  • Due to the ability of Hsps to activate DCs directly by chaperoning tumor antigens upon their release [28], it is possible that both local and regional immune stimulation can be achieved with hyperthermia.
  • support the use of hyperthermia as an inducer of Hsps to serve as ‘danger signals’, activating antitumor immune responses
  • whole-body hyperthermia not only augments immune responses, but also stimulates the migration of skin-derived DCs to draining lymph nodes

      This allows for the activation of lymphocytes by the activated dendritic cells.
  • suggest a valuable role of hyperthermia in DC cancer vaccine strategies

    • Nathan Goodyear
      Nathan Goodyear on 04 Aug 19
       
      Hyperthermia increased NK cell activation, proliferation, and infiltration, which equals increased cytotoxicity.
  • exposure to fever-range hyperthermia resulted in improved endogenous NK-cell cytotoxicity to several cancer types
  • improved activation and function of DCs and NK cells following hyperthermia
  • Hyperthermia increases the expression ICAM-1 a key adhesion molecule,
  • The combined effects of hyperthermia on lymphoid tissue endothelium and lymphocytes can promote immune surveillance and increase the probability of naive lymphocytes leaving the circulation and encountering their cognate antigen displayed by DCs in lymphoid organs.
  • In independent clinical studies, whole-body hyperthermia resulted in a transient decrease in circulating lymphocytes in patients with advanced cancer [12, 94, 99, 100], a finding which mirrored observations in animal models in which lymphocyte entry into lymph noeds was increased following hyperthermia treatment [93]. Enhanced recruitment of lymphocytes to lymphoid tissues may be exploited in the treatment of malignancies.
  • The initial tumor antigen presentation and initiation of clonal expansion of CTLs transpires in the lymph nodes and cannot take place outside this specialized compartment
  • the ability of DCs present in the lymph nodes to stimulate an anti-tumor immune response is critical
  • hyperthermia has been shown to improve immune surveillance by T-cell
  • and to increase DC trafficking to lymph nodes
