Effects of trypsin treatment on insulin and concanavalin A binding to, and glucose and proline transport in, dissociated R3230AC mammary adenocarcinoma cells were examined. Reduction of binding of 125I-labelled insulin was dependent on the amount of trypsin used, the temperature and the time of the
BACKGROUND
Proline-directed protein kinase F(A) (PDPK F(A)) was originally identified as a specific phosphatase activating factor, but has subsequently been demonstrated as a multisubstrate PDPK possibly involved in the regulation of diverse malignant characteristics of various types of human
Five-year survival is limited to 60% in renal cancer patients at diagnosis. Due to the cancer's resistance to conventional treatments and associated high morbidity, we investigated the antimetastatic effects of a specific nutrient mixture (NM) containing lysine, proline, arginine, ascorbic acid and
Tissue architecture contributes to pancreatic ductal adenocarcinoma (PDAC) phenotypes. Cancer cells within PDAC form gland-like structures embedded in a collagen-rich meshwork where nutrients and oxygen are scarce. Altered metabolism is needed for tumour cells to survive in this environment, but the
OBJECTIVE
Resistance to gemcitabine remains a key challenge in the treatment of pancreatic ductal adenocarcinoma (PDAC), necessitating the constant search for effective strategies for a priori prediction of clinical outcome. While the existing studies focused on aberration of drug disposition genes
Gallbladder cancer (GBC) is a rare malignancy, associated with poor disease prognosis with a 5-year survival of only 20%. This has been attributed to late presentation of the disease, lack of early diagnostic markers and limited efficacy of therapeutic interventions. Elucidation of molecular events
UNASSIGNED
Proline-rich/Ca2+-activated tyrosine kinase 2 (PYK2) belongs to the non-receptor tyrosine kinase family, regulates downstream signaling via catalyzing protein phosphorylation. We aimed to investigate clinical significance and mechanisms of PYK2 in colon adenocarcinoma
OBJECTIVE
New-onset diabetes in pancreatic adenocarcinoma is due to a combination of insulin resistance and decreased β-cell function. Its differentiation from the common type 2 diabetes is the prerequisite for early diagnosis of pancreatic adenocarcinoma. Little attention has been paid to
It was previously shown that the administration of dexamethasone (Dex) to mice bearing mammary adenocarcinoma caused the collagen content of the tumor capsule to be decreased by 50%, but collagenase and other neutral protease activities of the tumor were the same as in the controls. These events
OBJECTIVE
Abnormal function of gene p53 is associated with the formation of various cancers including gastric cancer. Recently, p53 codon 72 polymorphism was extensively studied to determine the risk factors responsible for cancer formation using the concept of single nucleotide polymorphism. In
The proline-specific peptidases, aminopeptidase P (EC 3.4.11.9) and dipeptidyl peptidase IV (EC 3.4.14.5), were measured in human tissue homogenates and physiological fluids. All tissues examined contained measurable aminopeptidase P and dipeptidyl peptidase IV activities. High specific activities
The amiloride-sensitive epithelial Na+ channel (ENaC) is an important component of the Na(+)-reabsorption pathway in many epithelia. The identification of three subunits of ENaC (alpha, beta and gamma), as well as results from a number of functional and biochemical studies, suggests that functional
Primary human lung adenocarcinomas were divided into two groups according to the degree of histologic differentiation: G2-moderately and G3-poorly differentiated tumors. Each group was compared with normal lung tissue in respect to prolidase activity, its ability to interact with specific antibody,
Rat mammary epithelium and adenocarcinomas derived from it synthesize type IV collagen, a structural protein of basement membranes. In cultures of cells, net production of collagen is stimulated 2-fold more than total cell protein by epidermal growth factor. Mammary adenocarcinoma cells also respond
Prostate adenocarcinoma is one of the leading causes of cancer related mortality in men but still limited knowledge is available about its associated functional SNPs including rs1042522 (Pro72Arg). The present study was undertaken to explore the association of this SNP with susceptibility to
