Summary
Dichloroacetate (DCA) combined with essential oil-blended curcumin (ECUR) significantly enhanced cancer cell death. This combination therapy boosts apoptosis, offering a promising approach to improve cancer treatment and reduce toxicity.
Area of Science:
- Oncology
- Pharmacology
- Cell Biology
Background:
- Dichloroacetate (DCA) and curcumin are recognized as potent anticancer drug candidates.
- Essential oil-blended curcumin (ECUR) represents a novel formulation for curcumin delivery.
Purpose of the Study:
- To investigate the synergistic effects of DCA and ECUR on hepatoma Huh-7 cells.
- To elucidate the mechanisms underlying the combined action of DCA and ECUR.
Main Methods:
- Cell viability was assessed using Muse™ Cell Cycle and Annexin V & Dead Cell assays.
- Mitochondrial-dependent apoptotic pathways were analyzed via western blot.
- Cellular morphology and oxidative stress were evaluated using Muse™ assays.
Main Results:
- The combination of DCA and ECUR significantly inhibited hepatoma cell survival.
- Enhanced apoptosis was observed, linked to the activation of mitochondria-dependent signaling.
- Significant alterations in cellular morphology confirmed the cytotoxic effects.
Conclusions:
- Apoptosis is the primary mechanism driving the synergistic antiproliferative effect of DCA and ECUR.
- Combining DCA with ECUR may allow for lower DCA doses, reducing toxicity and oxidative damage.
- This 'add-on' strategy holds significant potential for enhancing current DCA-based cancer therapies.

01:20Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
1.7K
Two NMR-active nuclei bonded to a central atom can be involved in geminal or two-bond coupling. Geminal coupling is commonly seen between diastereotopic protons in chiral molecules and unsymmetrical alkenes, among others.
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...

01:22Spin–Spin Coupling: Three-Bond Coupling (Vicinal Coupling)
1.5K
Vicinal or three-bond coupling is commonly observed between protons attached to adjacent carbons. Here, nuclear spin information is primarily transferred via electron spin interactions between adjacent C‑H bond orbitals. This generally favors the antiparallel arrangement of spins, so 3J values are usually positive.
The extent of coupling depends on the C‑C bond length, the two H‑C‑C angles, any electron-withdrawing substituents, and the dihedral angle between the involved orbitals. The...

01:21G-protein Coupled Receptors
132.0K
G-protein coupled receptors are ligand binding receptors that indirectly affect changes in the cell. The actual receptor is a single polypeptide that transverses the cell membrane seven times creating intracellular and extracellular loops. The extracellular loops create a ligand specific pocket which binds to neurotransmitters or hormones. The intracellular loops holds onto the G-protein.

01:17Spin–Spin Coupling: One-Bond Coupling
1.5K
Coupling interactions are strongest between NMR-active nuclei bonded to each other, where spin information can be transmitted directly through the pair of bonding electrons. While nuclei polarize their electrons to the opposite spins, the bonding electron pair has opposite spins. Configurations with antiparallel nuclear spins are expected to be lower in energy. When coupling makes antiparallel states more favorable, J is considered to have a positive value. The one-bond coupling constant, 1J,...

00:52Potential Energy
42.7K
The energy stored by a structure and location of matter in space is called potential energy. For instance, raising a kettlebell changes its spatial location and increases its potential energy. Similarly, a stretched rubber band contains potential energy which, under certain conditions, can be converted into other forms of energy, such as kinetic energy.
Chemical bonds that form attractive forces between atoms also contain potential energy, called chemical energy. When a chemical reaction...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...
