HW12
HW12 is a scrambled peptide control with no EGFR ligand activity. HW12 shows low cellular uptake levels in EGFR-positive cells. HW12 exerts weak growth inhibitory effects on pancreatic cancer. HW12 serves as a scrambled peptide control for EGFR-targeted GE11 (HY-P10128)-conjugated mixed micelles. HW12 can be used in pancreatic cancer research.

Biological Activity
The HW12 peptide can be successfully conjugated with MAL-PEG-PCD via a thiol-maleimide addition reaction to form HW12-PEG-PCD, and this result is confirmed by 1H NMR analysis[1].
The cellular uptake of FC-labeled HW12-linked mixed micelles (12 h) by MIA PaCa-2 cells is significantly lower than that of GE11-conjugated mixed micelles, indicating that HW12 cannot mediate EGFR-specific cellular uptake[1].
HW12-linked mixed micelles (60-500 nM GEM; 72 h) exhibit lower cytotoxicity against MIA PaCa-2 cells than GE11-linked mixed micelles, with an IC50 of 126.58 nM[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Line:MIA PaCa-2 pancreatic cancer cells
-
Concentration:HW12-linked mixed micelles with GEM concentrations of 60, 500 nM
-
Incubation Time:72 h
-
Result:Showed lower cytotoxicity than GE11-linked mixed micelles and unmodified micelles at all tested GEM concentrations.
Reached an IC50 value of 126.58 nM, which was 1.3-fold higher than the IC50 of GE11-linked mixed micelles (95.32 nM) and 1.1-fold higher than the IC50 of unmodified micelles (116.91 nM).

Animal Model:athymic nude mice (6-8 week-old)[1]
-
Dosage:40 mg/kg equivalent dose of gemcitabine
-
Administration:i.v.; once weekly; 3 weeks
-
Result:Showed minimal tumor growth inhibition compared to GE11-linked mixed micelles.
Resulted in significantly higher tumor bioluminescence, volume, and weight than in GE11-linked mixed micelle-treated mice.
Induced more Ki-67 staining, less cleaved caspase-3 staining, fewer necrotic tumor areas, less TUNEL-positive tumor and endothelial cell apoptosis, and higher tumor microvessel density compared to GE11-linked mixed micelles.
Caused no abnormal body weight changes.
Led to no pathological changes detected in major organs (heart, liver, kidney).
