Authors: Buck E, Sprick M, Gaida MM, Grüllich C, Weber TF, Herpel E, Bruckner T, Koschny R Abstract Recently, a tumor-autonomous cytochrome P450 (CYP)-3A5-mediated resistance to cancer therapy has been demonstrated in pancreatic ductal adenocarcinoma. Expression of CYP3A5, which is involved in the degradation of irinotecan, has also been reported in colorectal cancer (CRC). The aim of the present study was to analyze CYP3A5 expression in the normal colon, colon adenoma, CRC and normal tissues, as well as to examine whether CYP3A5 expression in CRC has an impact on tumor response to irinotecan treatment. Immuno...

ConclusionsH-Zt/g4-MMAE is superior in eradication of pancreatic cancer xenografts with favorable pharmacokinetic profiles and manageable toxicological activities. These findings warrant the transition of H-Zt/g4-MMAE into clinical trials in the future.

Abstract SRC and its activated form, phospho-SRC (pSRC), are aberrantly activated in pancreatic cancer and SRC represents a potential target for pancreatic cancer therapy. In this paper, we examined the inhibitory effect of dasatinib, a potent SRC inhibitor in combination with paclitaxel or gemcitabine on human and murine pancreatic cancer cell lines. The results showed that p-SRC can be highly expressed in most human and mouse pancreatic cancer cell lines compared with normal human cell lines and can be induced by paclitaxel or gemcitabine in HPAC cells. Dasatinib can enhance the efficacy of paclitaxel or gemcita...

In conclusion, GA micelles which showed high-efficiency anti-tumor effect in vitro and in vivo may serve as a candidate for pancreatic cancer therapyGraphical abstractMonomethyl poly(ethylene glycol)-poly(ε-caprolactone)-poly(trimethylene carbonate) (MPEG-P(CL-ran-TMC)) copolymer was synthesized, which could encapsulate GA by a single-step solid dispersion and form nano-sized micelles. The MPEG-P(CL-ran-TMC) based nano-formulation of GA could improve the anti-tumor effect in vivo, which may serve as a candidate for pancreatic cancer therapy.

Publication date: Available online 27 February 2019Source: International Journal of PharmaceuticsAuthor(s): Cenk Daglioglu, Fatma Necmiye KaciAbstractChemotherapy frequently involves combination treatment protocols to maximize tumor cell killing. Unfortunately these intensive chemotherapeutic regimes, often show disappointing results due to the development of drug resistance and higher nonspecific toxicity on normal tissues. In cancer treatment, it is critically important to minimize toxicity while preserving efficacy. We have previously addressed this issue and proposed a nanoparticle-based combination therapy involving b...

About half of all Americans are cremated when they die. So when a 69-year-old man was cremated in Arizona in 2017, it didn’t seem out of the ordinary — until doctors learned that his body may have put others at risk of radiation exposure. In 2017, the man was admitted to a hospital for low blood pressure treatment, according to a new research letter published in JAMA. But unbeknownst to his doctors, the man had been treated at the Mayo Clinic Arizona just the day before, where he had been injected with lutetium 177, a radiopharmaceutical used to combat his pancreatic cancer. When the man died two days after bei...

tis CA Abstract Pancreatic ductal adenocarcinoma (PDA) is characterized by abundant infiltration of tumor-associated macrophages (TAMs). TAMs have been reported to drive resistance to gemcitabine, a frontline chemotherapy in PDA, though the mechanism of this resistance remains unclear. Profiling metabolite exchange, we demonstrate that macrophages programmed by PDA cells release a spectrum of pyrimidine species. These include deoxycytidine, which inhibits gemcitabine through molecular competition at the level of drug uptake and metabolism. Accordingly, genetic or pharmacological depletion of TA...

DTLP showed bispecific binding activities to EGFR/HER ‐2 in vitro and in vivo. DTLL showed potent anti‐pancreatic cancer efficacy in CDX and PDX mouse models of human pancreatic cancer 3. DTLL had an antineoplastic effect by inhibited AKT/mTOR and PD‐1/PD‐L1 signal pathways in human pancreatic cancer. AbstractPancreatic ductal adenocarcinoma (PDAC) is a refractory malignant tumor with poor prognosis, limited chemotherapeutic efficacy, and only about 5% of 5 ‐year survival rate. We generated a dual‐targeting ligand‐based lidamycin (DTLL) to investigate its efficacy against pancreatic cancer after preparing its...

This study showed that potential vicious cycles underlying ARDs are quite diverse and unique, triggered by diverse and unique factors that do not usually progress with age, thus casting doubts on the possibility of discovering the single molecular cause of aging and developing the single anti-aging pill. Rather, each disease appears to require an individual approach. However, it still cannot be excluded that some or all of these cycles are triggered by fundamental processes of aging, such as chronic inflammation or accumulation of senescent cells. Nevertheless, experimental data showing clear cause and effect relationships...
