Heme Oxygenase 2/Hemlet 2 [B3]
Description Heme Oxygenases are microsomal enzymes that cleave heme to produce the antioxidant biliverdin, inorganic iron and carbon monoxide (CO). The activity of Heme Oxygenase 1 (HO-1), also designated HSP 32, is highly inducible in response to numerous stimuli, including heme, heavy metals, hormones and oxidative stress. Heme Oxygenase 2, in contrast, appears to be constitutively expressed in mammalian tissues. Heme Oxygenase 2 is involved in the production of carbon monoxide (CO) in brain, where CO is thought to act as a neurotransmitter. The CO signaling system closely parallels the signaling pathway involving nitric oxide, and regulation of the two systems is closely linked. Heme Oxygenase 3 is found in the spleen, liver, thymus, prostate, heart, kidney, brain and testis. A poor Heme catalyst, Heme Oxygenase 3 has two heme regulatory motifs that may be involved in Heme binding.

Hepatocyte Specific Antigen (HSA) (HepPar1) [OCH1E5]
Description Hepatocyte Specific Antigen (HSA) has been demonstrated consistently in the vast majority of Hepatocellular Carcinomas. Studies have shown the utility of HSA in the differential diagnosis of Hepatocellular Carcinoma, Cholangiocarcinoma and Hepatoblastomas. HSA recognizes both benign and malignant liver derived tissues including such tumors as Hepatoblastoma, Hepatocellular Carcinoma, and Hepatic Adenoma. It recognizes both normal adult and fetal liver tissue. The typical pattern is a granular cytoplasmic staining. This antibody is useful in differentiating Hepatocellular Carcinomas with adenoid features from Adenocarcinomas, either primary in the liver or metastatic lesions to the liver. In recognizing Hepatoblastoma, it is useful in differentiating this entity from other small round cell tumors.

HER2 [ERBB2/3257]
Description HER-2 neu (also known as c-erbB-2) is a member of the epidermal growth factor receptor (EGFR) family. It is a cell membrane surface-bound tyrosine kinase and is normally involved in the signal transduction pathways leading to cell growth and differentiation.

HES1/ES1/c21orf33 [E5]
Description The Drosophila Hairy and enhancer of split genes encode basic helix-loophelix (bHLH) transcriptional repressors that function in the Notch signaling pathway and control segmentation and neural development during embryogenesis. The mammalian homolog of Drosophila Hairy and enhancer of split are the HES gene family members HES1-6, which also encode bHLH transcriptional repressors that regulate myogenesis and neurogenesis. The HES family members form a complex with TLE, the mammalian homolog of groucho, and this interaction is mediated by the carboxy-terminal WRPW motif of the HES proteins. The HES/TLE complex functions by directly binding to DNA instead of interfering with activator proteins. Most HES family members, including HES1 and HES5, preferentially bind to the N box (CACNAG) as opposed to the E box (CANNTG). HES1 and HES2 are expressed in a variety of adult and embryonic tissues.

HIF-1 alpha [H1α67]
Description The HIF-1 Alpha subunit of hypoxia-inducible factor 1 is a transcription factor that functions as a master transcriptional regulator of the adaptive response to hypoxia. HIF-1 activates the transcription of many genes, thus playing a role in various biological processes, including cardiovascular development, angiogenesis, energy metabolism, and cell survival.

HIF-2 alpha/EPAS1 [190b]
Description Hypoxia-inducible factor (HIF) is essential for the cellular response to hypoxia. Under normoxia conditions, the α subunit of HIF is ubiquitinated by von Hippel-Lindau (VHL) protein and is degraded in the ubiquitin/proteasome pathway. Hypoxia inhibits the degradation of the α subunit, which leads to its stabilization. HIF, in turn, regulates the transcription of a variety of genes that respond to hypoxia conditions. There are several isoforms of the HIF α subunit. Studies have found that HIF-1α and HIF-2α expression is increased in some human cancers. HIF-1α has both pro- and anti-proliferative activities, whereas HIF-2α does not possess anti-proliferative activity. Therefore, HIF-2α likely plays an important role in tumorigenesis.

Histone H1 (Nuclear Marker) [AE-4]
Description Eukaryotic histones are basic and water-soluble nuclear proteins that form hetero-octameric nucleosome particles by wrapping 146 base pairs of DNA in a left-handed super-helical turn sequentially to form chromosomal fiber. Two molecules of each of the four core histones (H2A, H2B, H3, and H4) form the octamer; formed of two H2A-H2B dimers and two H3-H4 dimers, forming two nearly symmetrical halves by tertiary structure. Over 80% of nucleosomes contain the linker Histone H1, derived from an intronless gene that interacts with linker DNA between nucleosomes and mediates compaction into higher order chromatin. Histones are subject to posttranslational modification by enzymes primarily on their N-terminal tails, but also in their globular domains. Such modifications include methylation, citrullination, acetylation, phosphorylation, sumoylation, ubiquitination and ADP-ribosylation.
