LC3s Cancer Research Results

LC3s, Autophagosome Proteins: Click to Expand ⟱
Source:
Type:
LC3s (MAP1-LC3A, B and C) are structural proteins of autophagosomal membranes, widely used as biomarkers of autophagy. Whether these three LC3 proteins have a similar biological role in autophagy remains obscure.
Protumorigenic: In many cases, especially in advanced cancers, increased autophagy (reflected by high LC3 levels) can support tumor growth by providing nutrients and promoting cell survival under stress conditions.
Antitumorigenic: Conversely, in early-stage tumors or in response to certain therapies, autophagy can act as a tumor suppressor by preventing the accumulation of damaged organelles and proteins.

4901- DCA,  Sal,    Dichloroacetate and Salinomycin as Therapeutic Agents in Cancer
- Review, NSCLC, NA
Glycolysis↓, DCA redirects mitochondrial metabolism away from glycolysis to OXPHOS by the inhibition of PDKs
OXPHOS↑,
PDKs↓,
ROS↑, DCA increases reactive oxygen species (ROS), which induce downstream changes in mitochondrial function, causing the selective apoptosis of cancer cells.
Apoptosis↑,
GlucoseCon↓, treatment with DCA decreased glucose consumption and lactate production in vitro in a manner that was statistically significant compared to the controls
lactateProd↓,
RadioS↑, it enhanced the sensitivity of A549 and H1299 cells to X-ray-induced cell killing
TumAuto↑, DCA has been shown to induce autophagy instead of inhibiting it.
mTOR↓, The DCA-induced induction of autophagy was found to be mediated by the generation of ROS, the inhibition of the mammalian targets of rapamycin (mTOR),
LC3s↓, Lu and colleagues found that LC3 decreased while p62 levels increased, both of which are hallmarks of autophagy inhibition
p62↑,
TumCG↓, In vivo studies have demonstrated that DCA inhibits the growth of A549 and H1975 tumor xenografts and enhances the survival of tumor-bearing nude mice
OS↑,
toxicity↝, the most clinically limiting side effect of DCA is peripheral neuropathy
ChemoSen↑, DCA exerts synergistic potential with the most widely used chemotherapy agent, paclitaxel, on NSCLC cells.
eff↑, DCA has also been shown to have anticancer synergies with various non-traditional agents, the most prominent of which is metformin.
eff↑, Another compound that DCA has been shown to have a strong synergism with is ivermectin.
Ferritin↓, SAL and its derivatives prevent the movement of iron from the lumen to the cytosol, triggering an iron-depletion reaction that is characterized by the rapid degradation of ferritin
CSCs↓, SAL has been shown to selectively target CSCs in vitro and in vivo, but its mode of action is not fully understood.
EMT↓, SAL has also been shown to suppress the epithelial–mesenchymal transition (EMT) as well as transforming growth factors (TGFs). EMT is a process that is pivotal to metastasis.
ROS↑, SAL triggers apoptosis by elevating intracellular ROS levels, leading to the translocation of Bax protein to the mitochondria, cytochrome c (Cytc) release, and the activation of caspase-3
Cyt‑c↑,
Casp3↑,
ER Stress↑, SAL was observed to upregulate ER stress-related proteins in a time-/dose-dependent manner
selectivity↑, SAL induced cell death in multiple apoptosis-resistant cancer cell lines, but not in normal healthy human cells
eff↑, Skeberdytė and colleagues were among the first to recognize that DCA had synergistic potential with SAL.
TumCG↓, DCA and SAL were found to significantly suppress tumor growth in vivo in the mice.

4729- Se,    Selenium regulates Nrf2 signaling to prevent hepatotoxicity induced by hexavalent chromium in broilers
*ROS↓, Studies have reported that selenium (Se), which is one of the essential trace elements of the poultry and participates in the oxidative metabolism, can alleviate Cr(Ⅵ)-induced organ damage by inhibiting oxidative stress,
*NRF2↑, levels of Nrf2, glutathione peroxidase 1 (GPx-1), NAD(P)H: quinone oxidoreductase 1 (NQO1), and mechanistic target of rapamycin (mTOR) in the Se&Cr group was upregulated
*GPx1↑,
*NQO1↑,
*mTOR↑,
*Beclin-1↓, along with decreased expression of Beclin 1, ATG5 and LC3 compared to the Cr group.
*ATG5↓,
*LC3s↓,
*hepatoP↑,
