Walnut (Juglans regia L.) contains approximately 20-25 % protein with abundant essential amino acids. The enzymatic hydrolysate of Persian walnut (Chandler) seed proteins was prepared by incubation with three different proteases, including pancreatic chymotrypsin and trypsin, and a microbial enzyme proteinase K. The hydrolysates were found to possess excellent antioxidant capacities. The peptide fractions scavenged the 2, 2'-anizo-bis-(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS) free radicals and inhibited the activity of reactive oxygen species...

Despite the substantial benefit of androgen deprivation therapy (ADT) for metastatic prostate cancer, patients often progress to castration-resistant disease (CRPC) that is more difficult to treat. CRPC is associated with renewed androgen receptor activity in tumor cells and restoration of tumor androgen levels through acquired intratumoral steroidogenesis (AIS). Although prostate cancer (PCa) cells have been shown to have steroidogenic capability in vitro, we previously found that benign prostate stromal cells (PrSCs) can also synthesize testosterone (T) from an adrenal precursor, DHEA, when stimulated with a hedgehog (Hh) pathway agonist, SAG...

Increasing number of genetic and cancer biology studies indicated a prominent role for tachykinin NK1 receptor (NK1R) in cancer cell growth and survival. Considering the fact that neoplastic lymphoid precursors in acute lymphoblastic leukemia (ALL) carry a three- to four-fold NK1R expression as compared to normal lymphocytes, using NK1R antagonist seems to be noteworthy in the treatment of ALL patients. In this study, we found that inhibition of NK1R with aprepitant, a selective high-affinity antagonist of the human NK1R, exerts cytotoxic and anti-proliferative effects against pre-B ALL-derived Nalm-6 cells either as single drug or in combination with doxorubicin...
