Everything Cures Melanoma...#7
And I recently reported this:
I like me some shrimp!!! Now their micro-RNA can suppress the stem like qualities of some melanoma cells???!!!
But there's still more...
The
Inhibitory Activity of Luzonicosides from the Starfish Echinaster
luzonicus against Human Melanoma Cells. Malyarenko, Dyshlovoy,
Kicha, et al. Mar
Drugs. 2017 Jul 18.
Malignant
melanoma is the most dangerous form of skin cancer, with a rapidly
increasing incidence rate. Despite recent advances in melanoma
research following the approval of several novel targeted and
immuno-therapies, the majority of oncological patients will
ultimately perish from the disease. Thus, new effective drugs are
still required. Starfish steroid glycosides possess different
biological activities, including antitumor activity. The current
study focused on the determination of the in vitro inhibitory
activity and the mechanism of action of cyclic steroid glycosides
isolated from the starfish Echinaster luzonicus-luzonicoside
A (LuzA) and luzonicoside D (LuzD)-in human melanoma RPMI-7951 and
SK-Mel-28 cell lines. LuzA inhibited proliferation, the formation of
colonies, and the migration of SK-Mel-28 cells significantly more
than LuzD. Anti-cancer activity has been ascribed to cell cycle
regulation and apoptosis induction. The molecular mechanism of action
appears to be related to the regulation of the activity of cleaved
caspase-3 and poly(ADP-ribose) polymerase (PARP), along with
Survivin, Bcl-2, p21 and cyclin D1 level. Overall, our findings
support a potential anti-cancer efficacy of luzonicosides A and D on
human melanoma cells.
Antitumor
activity and expression profiles of genes induced by sulforaphane in
human melanoma cells. Arcidiacono, Ragonese, Stabile, et al. Eur
J Nutr. 2017 Sep 1.
Human
melanoma is a highly aggressive incurable cancer due to intrinsic
cellular resistance to apoptosis, reprogramming, proliferation and
survival during tumour progression. Sulforaphane (SFN), an
isothiocyanate found in cruciferous vegetables, plays a role in
carcinogenesis in many cancer types. However, the cytotoxic molecular
mechanisms and gene expression profiles promoted by SFN in human
melanoma remain unknown.
Three
different cell lines were used: two human melanoma A375 and 501MEL
and human epidermal melanocytes (HEMa). Cell viability and
proliferation, cell cycle analysis, cell migration and invasion and
protein expression and phosphorylation status of Akt and p53 upon SFN
treatment were determined. RNA-seq of A375 was performed at different
time points after SFN treatment.
We
demonstrated that SFN strongly decreased cell viability and
proliferation, induced G2/M cell cycle arrest, promoted
apoptosis through the activation of caspases 3, 8, 9 and hampered
migration and invasion abilities in the melanoma cell lines.
Remarkably, HEMa cells were not affected by SFN treatment.
Transcriptomic analysis revealed regulation of genes involved in
response to stress, apoptosis/cell death and metabolic processes. SFN
upregulated the expression of pro-apoptotic genes, such as p53, BAX,
PUMA, FAS and MDM2; promoted cell cycle inhibition and growth arrest
by upregulating EGR1, GADD45B, ATF3 and CDKN1A; and simultaneously
acted as a potent inhibitor of genotoxicity by launching the
stress-inducible protein network (HMOX1, HSPA1A, HSPA6, SOD1).
Overall,
the data show that SFN cytotoxicity in melanoma derives from complex
and concurrent mechanisms during carcinogenesis, which makes it a
promising cancer prevention agent.
Anti-Melanogenic Activity and
Cytotoxicity of Pistacia vera Hull on Human Melanoma SKMEL-3 Cells.
Sarkhail, Salimi, Sarkheil, et al. Acta Med Iran. 2017 Jul.
Pistacia vera seed is a common food
and medicinal seed in Iran. It's hull (outer skin) as a significant
byproduct of pistachio, is traditionally used as tonic, sedative and
antidiarrheal and has been shown to be a rich source of antioxidants.
The aim of the present study is to evaluate the anti-melanogenic
activity of the pistachio hulls in order to discover a new
alternative herbal agent to treat skin hyperpigmentation disorders.
In this work, antioxidant and anti-tyrosinase activity of MeOH
extract from Pistacia vera hull (MPH) were evaluated in vitro,
respectively, by DPPH radical scavenging and mushroom tyrosinase
activity assays. Then the effect of MPH on the melanin content,
cellular tyrosinase activity and cytotoxicity (MTT assay) on human
melanoma SKMEL-3 cell were determined followed by 72 h incubation.
The results indicated that MPH had valuable DPPH radical scavenging
effect and weak anti-tyrosinase activity when compared to the
well-known antioxidant (BHT) and tyrosinase inhibitor (kojic acid),
respectively. MPH, at a high dose (0.5 mg/mL), showed significant
cytotoxic activity (~63%) and strong anti-melanogenic effect (~57%)
on SKMEL-3 cells. The effect of MPH in the reduction of melanin
content may be related to its cytotoxicity. The results obtained
suggest that MPH can be used as an effective agent in the treatment
of some skin hyperpigmentation disorders such as melanoma.
Molecular characterisation, ontogeny
and expression analysis of melanoma differentiation-associated factor
5 (MDA5) from Asian seabass, Lates calcarifer. Paria, Makesh,
Chaudhari, et al.
Dev
Comp Immunol. 2017 Sep 15.
MDA5 is the pivotal member of the retinoic acid-inducible gene I
(RIG-I)-like receptors (RLRs) and is reported to play a crucial role
in type I IFN-mediated responses against pathogen-associated
molecular patterns (PAMPs), especially nucleic acids. In this study,
we have identified and cloned the full-length cDNA sequence of MDA5,
which comprises 3398 nucleotides and encodes for a putative protein
of 978 AA length, in Asian seabass, Lates calcarifer. From the
putative amino acid sequence of AsMDA5, four different conserved
domains could be predicted: two N-terminal CARD domains, a DExDc
domain, a HELICc domain and a C-terminal RIG-1_C-RD domain. The mRNA
transcript of AsMDA5 could be detected in all the 11 tissues tested
in healthy animals with the highest expression in heart followed by
gill and skin. The ontogenetic expression profile showed constitutive
expression in developmental stages starting from unfertilized eggs,
which implies the possibility of maternally acquired immunity of RLRs
in offspring. The viral analogue poly I:C could modulate the AsMDA5
expression both in vivo and in vitro. In all the tissues, AsMDA5
expression was found to be highly regulated following injection with
poly I:C with the highest expression observed in kidney. The
expression level of AsMDA5 was found to be modulated at different
time-points following challenge with Gram-negative bacterium, Vibrio
alginolyticus, and Gram-positive bacterium, Staphylococcus aureus.
Similarly, noticeable change in AsMDA5 expression was detected in
SISK cell line induced with either LPS or PGN. The observations made
in this study suggest that in euryhaline marine teleosts like Asian
seabass, MDA5 gene serves as one of the pivotal receptor for the
detection of viral and bacterial PAMP, and might play an important
antimicrobial role during early embryonic development.
Antiproliferative
Activity of Walnut (Juglans regia L.) Proteins and Walnut Protein
Hydrolysates. Carrillo, Gomez-Ruiz, Ruiz, Carvalho. J
Med Food. 2017 Sep 25.
Proteins
from Juglans regia L. were isolated. Then, proteins were hydrolyzed
with different enzymes. Antiproliferative activity of proteins and of
the protein hydrolysates of J. regia L. were evaluated using the
sulforhodamine B method. Glutelin and prolamin proteins presented a
high antiproliferative activity against cancer cells PC-3 (prostate)
and K-562 (leukemia) with values of 43.9 and 84.4 μg/mL,
respectively. The highest inhibitory effect observed was 50% at
0.25 μg/mL concentration in gastrointestinal digestion with pepsin
and corolase pp in a dose-dependent manner against cancer cell UACC62
(melanoma). Pepsin hydrolysate showed inhibitory effects against
cancer cell UACC62 (melanoma) with a concentration of 71.0 μg/mL.
The effects were studied in a dose-dependent manner. The hydrolysate
obtained with neutrase enzyme presented inhibitory effects against
cancer cell UACC62 (melanoma) at a concentration of 25 μg/mL.
Neither proteins nor protein hydrolysates presented cytotoxicity
against normal cell assay VERO (epithelial).
In
vitro and in vivo anti-cancer activity of dichloromethane fraction of
Triticum aestivum sprouts. Ki, Poudel, Lee, et al. Biomed
Pharmacother. 2017 Sep 29.
Triticum
aestivum sprouts (TA) contain significant amounts of chlorophyll,
minerals, enzymes, and other functional entities. Furthermore, TA
extracts have been shown to possess anti-obesity, anti-diabetic and
hepatoprotective effects and are believed to help blood flow,
digestion, and general detoxification of the body. In this study, the
mechanism underlying the anti-cancer effects of a dichloromethane
fraction of TA (TDF) was investigated in vitro and in vivo. In vitro
study was done by examining cancer cells growth, morphological
changes, cell cycles, expressions of death receptors and
apoptosis-linked proteins in wide range of human cancer cell lines.
To investigate the effect of TDF in vivo, C57BL/6 mice were injected
with B16 melanoma cells and orally administered TDF. TDF markedly
inhibited cancer cell growth and induced cellular morphological
alterations, cell cycle arrest and apoptosis, and enhanced the
expressions of death receptors (DR)-4, 5, and 6 in cell lines. In
addition, TDF regulated the expressions mitochondrial
apoptosis-linked proteins and induced caspase-dependent cell death.
It also significantly enhanced phosphorylation of ERK1/2 and JNK, but
not p38, whereas inhibited the activation of NF-κB in cancer cells.
In our mouse model, TDF significantly suppressed B16 melanoma growth,
to an extent similar to cisplatin (reference control) and augmented
immunomodulatory cytokines. In brief, this study presents the
mechanism responsible for the anti-cancer effects of TDF in vitro and
in vivo.
WOW!! So....to cure our melanoma, we need a little smidge of starfish goo/hormones, cruciferous veggies (Think cabbage, collards, broccoli, brussel sprouts.....stuff I've eaten all my life!!!), the HULL from pistachios (Just the hull, mind you!! What do these folks think I am, a termite????), walnut protein (Uh, NO!! Not for me...as a person with anaphylaxis to tree nuts, I don't think that will turn out very well!!), TA sprouts (That's wheat sprouts, folks!) and my favorite from this list, Asian Sea Bass. How do you get Asian Sea Bass, you might ask? Just call them...real loud!!!
If any of these work out that will be great! Til then....I'm just gonna enjoy Bert and Ernie!! - c
