skin neoplasms/protease

Kallikrein-related peptidase 6 (KLK6) is a serine protease that is aberrantly altered in various types of cancer but its role in non-melanoma skin cancer has not been investigated. KLK6 is active in epidermis and has been linked to normal skin differentiation. Thus, we investigated whether it could

Growth and metastasis of solid neoplasms require the recruitment of a supporting tumor stroma. A highly consistent trait of tumor stromal fibroblasts in most epithelial cancers is the induction of fibroblast activation protein (FAP), a member of the serine protease family. Recently it was

The new serine protease inhibitor, ONO-3403 is an analog of FOY-305 (Foypan). The IC50s values of ONO-3403 toward serine proteases, such as trypsin, plasmin, kallikrein and thrombin are much lower than that of FOY-305. To investigate the growth-suppressing effect of ONO-3403 on

The orally active serine protease inhibitor ONO-3403 is an analog of FOY-3403 that has more potent protease-inhibitory activity. In the present study, oral administration of ONO-3403 was used to challenge 3-methylcholanthrene-induced carcinoma. This drug was administered 3 times daily for 9 weeks

3-Methylcholanthrene-induced tumor was challenged with a low molecular synthetic protease inhibitor, [N,N-dimethylcarbamoylmethyl 4-(4-guanidinobenzoyloxy)-phenylacetate] methanesulfate. This drug at a dosage of 10 mg/kg or 20 mg/kg was administered by ip injection to 20 mice each harboring a

Tumor-stroma interactions play a significant role in tumor development and progression. Alterations in the stromal microenvironment, including enhanced vasculature (angiogenesis), modified extracellular matrix composition, inflammatory cells, and dys-balanced protease activity, are essential

Three fish retroviruses infecting walleyes constitute the recently recognized genus called epsilonretrovirus. The founding member of this group, walleye dermal sarcoma virus (WDSV), induces benign skin tumors in the infected fish and replicates near 4 degrees C. While the viral genomic sequence is

Protease inhibitors, which are common constituents of seeds (rice, beans, and maize) have been shown to inhibit breast, colon, and skin cancers in animal experiments. Epidemiological studies have shown that diets rich in these components (ie seed proteins) decrease the occurrence of prostatic,

Many tumor promoters are inflammatory agents that stimulate the formation of oxygen radicals (.O2-) and hydrogen peroxide (H2O2) in phagocytic neutrophils. The neutrophils use the oxygen radicals to kill bacteria, which are recognized by the cell membrane of phagocytic cells causing a signal to

The effect of a microbial protease inhibitor, leupeptin, on the content of polyamine in the mouse skin was examined during the early stage of tumorigenesis induced by a single application of 7,12-dimethylbenz[a]anthracene (DMBA) and repeated application of croton oil thereafter. Polyamine content in

For decades, proteases have been associated with cancer progression due to the ability of some members of this large group of enzymes to degrade tumor cell surroundings, thereby facilitating cancer invasion and dissemination. However, the generation of mouse models deficient in proteases has

Proteases are reported to play an essential role in the proliferative, invasive, and metastatic potential of malignant tumor cells. Metastasis is characterized by a complex series of interactions between tumor cells and their environment. Tumor expansion and invasion are associated with the

The effect of the potent synthetic protease inhibitor [N,N-dimethylcarbamoylmethyl 4-(4-guanidinobenzoyloxy)-phenylacetate] methanesulfate (FOY-305) on skin carcinogenesis in ddY mice was examined over a total observation period of 105 days. Administration of 0.1% FOY-305 in the diet suppressed the

Malignant transformation of mouse skin by chemical carcinogens and tumor promoters, such as the phorbol ester 12-O-tetradecanoylphorbol-13-acetate, is a multistage process leading to the formation of squamous cell carcinomas. In an effort to identify target genes whose expression is associated with

In an effort to increase the efficiency and cure rate of nonmelanoma skin cancer (NMSC) excisions, we have developed a point-of-care method of imaging and evaluation of skin cancer margins. We evaluate the skin surgical specimens using a smart, near-infrared probe (6qcNIR) that fluoresces in the
