S 100 protein marker

Several members of the S100 protein family are useful as markers for certain tumors and epidermal differentiation. It can be found in melanomas , [8] 100% of schwannomas, 100% of neurofibromas (weaker than schwannomas), 50% of malignant peripheral nerve sheath tumors (may be weak and/or focal), paraganglioma stromal cells, histiocytoma and. A heterogeneous group of 159 tumours was studied for the presence of S-100 protein by the immunoperoxidase technique in order to determine whether this marker may be of value in facilitating immunocytochemical diagnosis. Among cases of melanocytic and pigmented lesions, S-100 was widely distributed

S-100 protein and neuron-specific enolase in cerebrospinal fluid and serum: markers of cell damage in human central nervous system. Persson L, Hårdemark HG, Gustafsson J, Rundström G, Mendel-Hartvig I, Esscher T, Påhlman S. The development of a radioimmunoassay for S-100 protein is described S-100 protein (S-100B) is the most widely used marker for peripheral nerve sheath tumors. Although S-100 protein is positive in all benign Schwann cell tumors, this marker shows relatively low sensitivity for MPNST (at most, around 50%)

Detection of S100 protein is a useful identifying marker. S100 protein, so named for its S-100 protein as a marker for melanocytic and other tumours Pathology. 1985 Apr;17(2):340-5. doi: 10.3109/00313028509063777. Authors A J Cochran, D R Wen. PMID: 2995906. S100 calcium-binding protein B (S100B) is a protein of the S-100 protein family.. S100 proteins are localized in the cytoplasm and nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation. S100 genes include at least 13 members which are located as a cluster on chromosome 1q21; however, this gene is.

S100 proteinProteini označeni kao S100 su grupa regulatornih proteina kojih ima najviše u stanicama centralnog nervnog sistema te u stanicama melanoma. Koristi se kao pomoć pri dijagnostici, praćenju razvitka bolesti te uspješnosti terapije. Iako je prisutan i kod ganglioma najviše se koristi za dijagnostiku melanoma, jer S100 ima dosta u melanocitima Die Proteine der Multigen-Familie S-100 sind Calcium-bindende Proteine mit niedriger Molekülmasse (9-13 kDa) und einer Vielzahl von zellulären Funktionen (z. B. Phosphorylierungen).. Zu den S-100 Proteinen gehören 19 Mitglieder, die in unterschiedlichsten Zelltypen exprimiert werden: . S100B wird vor allem in Gliazellen aber auch in Adipozyten, Melanozyten und Chondrozyten exprimiert S100 je označení skupiny peptidů s poměrně nízkou molekulovou hmotností (9-13 kDa), které jsou charakterizovány přítomností dvou EF-hand domén (závit-smyčka-závit). S100 proteiny váží kalcium, některé typy mohou vázat i zinek a měď. Lokalizovány jsou především intracelulárně, kde se podílejí na řadě nitrobuněčných dějů, zejm. na kontraktilitě. Le proteine S100 sono una famiglia di proteine a basso peso molecolare presente nei vertebrati, caratterizzate da due siti di legame per il calcio con struttura elica-ansa-elica ().Esistono almeno 21 tipi di proteine S100.Il nome S100 deriva dalla solubilità al 100% di queste in solfato d'ammonio a pH neutro

Referitor la prima indicaţie, trebuie menţionat că acest marker nu trebuie utilizat în scop de screening sau diagnostic pentru melanomul malign. S100 se corelează cu volumul tumoral, astfel că la pacienţii cu melanom malign aflaţi în stadiile II, III şi IV nivelurile serice crescute indică progresia bolii S100B protein is expressed constitutively by brain astrocytes. Serum S100B protein concentration in Stage II-III-IV melanoma is a reliable prognostic marker. The serum level of S100B protein is significant independent prognostic marker in respect to disease specific survival, it is a relevant marker for therapy monitoring and patient follow-up The S-100 is an acidic calcium-binding protein (molecular weight, 21 000) constituting a major component of the cytosol, predominantly in astroglial cells. 1 2 3 The protein consists of two subunits (α and β ). S-100 ββ is present in high concentration in glial and Schwann cells, S-100 αβ in glial cells and S-100 αα is found in striated muscles, heart, and kidney. 2 Recently.

  1. S100: The protein encoded by this gene is a member of the S100 family of proteins containing 2 EF-hand calcium-binding motifs. S100 proteins are localized in the cytoplasm and/or nucleus of a wide range of cells, and involved in the regulation of a number of cellular processes such as cell cycle progression and differentiation
  2. Summary: Purpose: S‐100 protein is a sensitive marker of various brain diseases; however, its role in epilepsy is controversially discussed in the literature. We therefore studied the temporal profile of serial concentrations of S‐100 protein in serum after secondarily generalized tonic-clonic seizures during video‐EEG monitoring
  3. It was concluded that S‐100 protein, mainly S 100α. exists in thyroid follicular cells, that it exists In higher quantity in most of the well differentiated lesions but in lower quantity in poorly differentiated or Undifferentiated lesions, and that 5100 protein, especially S‐100α, is a differentiation marker in carcinoma of thyroid.

  5. It has been shown that S-100 is a valid marker of isolated damage to the central nervous system. However, we agree with the authors' conclusion that given a laboratory method that is not absolutely specific for S-100b, S-100 protein is of limited use as a marker of cerebral damage in patients after heart surgery

Mindkét marker esetében az emelkedett koncentráció rö-videbb túléléssel járt együtt. Következtetések: Tanulmányunkban az S-100B protein bizonyult szenzitívebbnek és specifikusabbnak.

In human brain tissue S-100 protein is mainly presented as two isoforms - bb homodimer (S-100b) and ab heterodimer (S-100a). Because of its predominant location in astroglial cells S-100 protein can be used as a sensitive and reliable marker for central nervous system injury

The astroglial protein S-100 is an established biochemical marker of central nervous system injury. The purpose of the present study was to validate the use of serum determinations of S-100 with. There is a correlation of 91.3% between S100 and FDG-PET studies (23 patients). S100 does not provide information on the sentinel lymph node biopsy. Conclusions: S100 is not useful to diagnose melanoma in its early stages but it is a good tumor marker for the follow-up and monitoring of melanoma patients Measurement of S-100B has been proposed as a biological marker of brain damage, e.g., head injury, cerebral hypoxia, and stroke , and of malignant melanoma.

In a miscellaneous group of tumours S-100 was demonstrated in chordomas, myoepitheliomas and Wilms' tumour with Schwann cell differentiation. Despite its presence in a wide array of cell types, S-100 protein continues to be an extremely useful marker especially for soft tissue and peripheral nervous system tumours
