now here is a nice picture to imagine: scorpion venom vs. her2+ breast cancer!
Toxicon. 2010 Sep 30. [Epub ahead of print]
Apoptogenic Peptides From Tityus discrepans Scorpion Venom Acting Against The SKBR3 Breast Cancer Cell Line.
D'Suze G, Rosales A, Salazar V, Sevcik C.
Laboratory on Cellular Neuropharmacology.
Abstract
Two novel peptides named neopladine 1 and neopladine 2 were purified from Tityus discrepans scorpion venom and found to be active on human breast carcinoma SKBR3 cells. Mass spec-trometry molecular masses of neopladine 1 and 2 were 29918 and 30388 Da, respectively. Their N-terminal sequences were determined by Edman degradation. The peptides induced apoptosis of SKBR3 cells but had a negligible effect on non-malignant MA104 monkey kidney cells. Neopladine 1 and 2 induced 6.3 and 4.1% of SKBR3 apoptosis, respectively, in 5hours of exposure; the effect was larger with more prolonged exposures. Inmunohistochemistry showed that neopladines bind to SKBR3 cell surface inducing FasL and BcL-2 expression.

Oh, lovely. Scorpions are my kryptonite and now they might be a key to HER2 cancer? Ironic, no? LOL.

Nov'03~ dX stage 2B
Dec'03~ Rt side mastectomy, Her2+, ER/PR+, 10 nodes out, one node positive
Jan'04~ Taxotere/Adria/Cytoxan x 6, NED, no Rads, Tamox. 1 year, Arimadex 3 mo., NED 14 mo.
Sept'05~ micro mets lungs/chest nodes/underarm node, Switched to Aromasin, T/C/H x 7, NED 6 months - Herceptin only
Aug'06~ micro mets chest nodes, & bone spot @ C3 neck, Added Taxol to Herceptin
Feb'07~ Genetic testing, BRCA 1&2 neg
Apr'07~ MRI - two 9mm brain mets & 5 punctates, new left chest met, & small increase of bone spot C3 neck, Stopped Aromasin
May'07~ Started Tykerb/Xeloda, no WBR for now
June'07~ MRI - stable brain mets, no new mets, 9mm spots less enhanced, CA15.3 down 45.5 to 9.3 in 10 wks, Ty/Xel working magic!
Aug'07~ MRI - brain mets shrunk half, NO NEW BRAIN METS!!, TMs stable @ 9.2
Oct'07~ PET/CT & MRI show NED
Apr'08~ scans still show NED in the head, small bone spot on right iliac crest (rear pelvic bone)
Sept'08~ MRI shows activity in brain mets, completed 5 fractions/5 consecutive days of IMRT to zap the pesky buggers
Oct'08~ dropped Xeloda, switched to tri-weekly Herceptin in combo with Tykerb, extend to tri-monthly Zometa infusion
Dec'08~ Brain MRI- 4 spots reduced to punctate size, large spot shrunk by 3mm, CT of torso clear/pelvis spot stable
June'09~ new 3-4mm left cerrebellar spot zapped with IMRT targeted rads
Sept'09~ new 6mm & 1 cm spots in pituitary/optic chiasm area. Rx= 25 days of 3D conformal fractionated targeted IMRT to the tumors.
Oct'09~ 25 days of low dose 3D conformal fractionated targeted IMRT to the bone mets spot on rt. iliac crest that have been watching for 2 years. Added daily Aromasin back into treatment regimen.
Apr'10~ Brain MRI clear! But, see new small spot on adrenal gland. Change from Aromasin back to Tamoxifen.
June'10~ Tumor markers (CA15.3) dropped from 37 to 23 after one month on Tamoxifen. Continue to monitor adrenal gland spot. Remain on Tykerb/Herceptin/Tamoxifen.
Nov'10~ Radiate positive mediastinal node that was pressing on recurrent laryngeal nerve, causing paralyzed larynx and a funny voice.
Jan'11~ MRI shows possible activity or perhaps just scar tissue/necrotic increase on 3 previously treated brain spots and a pituitary spot. 5 days of IMRT on 4 spots.
Feb'11~ Enrolled in T-DM1 EAP in Denver, first treatment March 25, 2011.
Mar'11~ Finally started T-DM1 EAP in Denver at Rocky Mountain Cancer Center/Rose on Mar. 25... hallelujah.

We've all had extract of Yew Tree in our veins (Taxol). I wouldn't object to scorpion venom, if it works.

I have pictures of me with the Tartikoff Foundation Yew Tree in Monaco's Jardin de Exotique... it's not nearly as sinister as a scorpion! But, I am always willing to do/take whatever is necessary...

The Chinese Kung Fu stories have long described using 'poision' to treat 'poision'. Scorpion is one of the most cited critters...
