Human tissue kallikreins are fifteen homologous genes encoding for secreted serine proteases and residing tandemly on chromosome 19q13.4. These enzymes are highly expressed in a variety of tissues and participate in diverse physiological processes. Human tissue kallikreins were found to be

The recently characterized human serine protease, Testisin, is expressed on premeiotic testicular germ cells and is a candidate type II tumor suppressor for testicular cancer. Here we report the cloning, characterization and expression of the gene encoding mouse Testisin, Prss21. The murine Testisin

Tazarotene-induced gene 1 (TIG1) encodes a protein that is a retinoid-regulated tumor suppressor. TIG1 is expressed in most normal tissues, and downregulation of TIG1 expression in multiple cancers is caused by promoter hypermethylation. Kazal-type serine protease inhibitor-2 (SPINK2) is a serine

Testisin is a recently identified human serine protease expressed by premeiotic testicular germ cells and is a candidate tumor suppressor for testicular cancer. Here, we report the characterization of the gene encoding testisin, designated PRSS21, and its localization on the short arm of human

The kallikrein gene family is comprised of genes that have either established or potential applications in prostate and breast cancer diagnostics. New members of the human kallikrein gene family have been recently identified. By using the positional candidate gene approach, we were able to clone a

Aim of this review article was to critically analyse the recently described zytogenetic and molecular markers for testicular germ cell tumors with regard to their clinical utility. The isochromosome i(12p) represents the most common and characteristic cytogenetic finding which already appears in

The role of caspase-3 (CPP32) protease in the molecular pathways of genistein-induced cell death in TM4 cells was investigated. Fluorescence microscopy with Hoechst-33258-PI nuclear stain was used to distinguish between apoptosis and necrosis pathways of cell death. The viability of the test cells

The Testisin gene (PRSS21) encodes a glycosylphosphatidylinositol (GPI)-linked serine protease that exhibits testis tissue-specific expression. Loss of Testisin has been implicated in testicular tumorigenesis, but its role in testis biology and tumorigenesis is not known. Here we have investigated

Human tissue kallikrein genes, located on the long arm of chromosome 19, are a subgroup of the serine protease family of proteolytic enzymes. Initially thought to consist of three members, the human kallikrein locus has now been extended and includes 15 tandemly located genes. These genes, and their

Aim of this review article was to critically analyze the recently described cytogenetic and molecular markers for testicular germ cell tumors with regard to their clinical utility. The isochromosme i(12p) represents the most common and characteristic cytogenetic finding which already appears in

I was deeply moved by David Sanford's Wall Street Journal article, which follows. As David's story recounts, he came to me in deep despair. He believed that there was little hope to escape what is commonly termed a "death sentence" from AIDS. With state-of-the-art treatment, he has regained

It has been proposed that proteases secreted by cancer cells facilitate tumor invasion and metastasis by degrading the components of extracellular membranes. The lysosomal cysteine protease cathepsin L is synthesized in large amounts and secreted by many malignantly transformed cells in culture. The

The introduction of highly active antiretroviral therapy (HAART) has changed dramatically the landscape of HIV disease. Deaths from AIDS-related diseases have been reduced by 75% since protease inhibitor therapy and combination antiretroviral therapy came into use in late 1995. While KS is

BACKGROUND The development of mass spectrometric (MS) techniques now allows the investigation of very complex protein mixtures ranging from subcellular structures to tissues. Body fluids are also popular targets of proteomic analysis because of their potential for biomarker discovery. Seminal plasma

The introduction of highly active antiretroviral therapy (HAART) has changed dramatically the landscape of HIV disease. Deaths from AIDS-related diseases have been reduced by 75% since protease inhibitor therapy and combination antiretroviral therapy came into use in late 1995. While KS is
