The intracellular transfer of information (biological activation/inhibition) through a signal pathway. In each signal transduction system, an activation/inhibition signal from a biologically active molecule (hormone, neurotransmitter) is mediated via the coupling of a receptor/enzyme to a second messenger system or to an ion channel. Signal transduction plays an important role in activating cellular functions, cell differentiation, and cell proliferation. Examples of signal transduction systems are the GAMMA-AMINOBUTYRIC ACID-postsynaptic receptor-calcium ion channel system, the receptor-mediated T-cell activation pathway, and the receptor-mediated activation of phospholipases. Those coupled to membrane depolarization or intracellular release of calcium include the receptor-mediated activation of cytotoxic functions in granulocytes and the synaptic potentiation of protein kinase activation. Some signal transduction pathways may be part of larger signal transduction pathways; for example, protein kinase activation is part of the platelet activation signal pathway.

Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

A hereditary disease characterized by multiple ectodermal, mesodermal, and endodermal nevoid and neoplastic anomalies. Facial trichilemmomas and papillomatous papules of the oral mucosa are the most characteristic lesions. Individuals with this syndrome have a high risk of BREAST CANCER; THYROID CANCER; and ENDOMETRIAL CANCER. This syndrome is associated with mutations in the gene for PTEN PHOSPHATASE.
The condition of a pattern of malignancies within a family, but not every individual's necessarily having the same neoplasm. Characteristically the tumor tends to occur at an earlier than average age, individuals may have more than one primary tumor, the tumors may be multicentric, usually more than 25 percent of the individuals in direct lineal descent from the proband are affected, and the cancer predisposition in these families behaves as an autosomal dominant trait with about 60 percent penetrance.
Mutagenesis where the mutation is caused by the introduction of foreign DNA sequences into a gene or extragenic sequence. This may occur spontaneously in vivo or be experimentally induced in vivo or in vitro. Proviral DNA insertions into or adjacent to a cellular proto-oncogene can interrupt GENETIC TRANSLATION of the coding sequences or interfere with recognition of regulatory elements and cause unregulated expression of the proto-oncogene resulting in tumor formation.

Ambiguous genitalia, impaired steroidogenesis, and Antley-Bixler syndrome in a patient with P450 oxidoreductase deficiency. (2/9)

Cytochrome P450 oxidoreductase deficiency is a recently established autosomal recessive disease characterised by ambiguous genitalia, impaired steroidogenesis, and skeletal malformations, referred to as Antley-Bixler syndrome. Clinical manifestations in affected patients are highly variable. We report on a girl with P450 oxidoreductase deficiency who presented with virilisation at birth. There was transient maternal virilisation during pregnancy as well. She was initially diagnosed with congenital adrenal hyperplasia caused by 21-hydroxylase deficiency and/or aromatase deficiency. At 1 year of age, skeletal abnormalities suggestive of Antley-Bixler syndrome were detected. Molecular analysis of the fibroblast growth factor receptor 2 (FGFR2) gene was normal but POR gene analysis showed that she was homozygous for an R457H missense mutation. The diagnosis, P450 oxidoreductase deficiency, was confirmed. Results of her endocrine studies and urinary steroid profiling are also presented.  (+info)

FGFR1 (Fibroblast growth factor receptor 1), also known as fms-related tyrosine kinase-2/Pfeiffer syndrome, is a member of the fibroblast growth factor receptor (FGFR) family. FGFR family is cell surface membrane receptor that possesses tyrosine kinase activity. When combined with appropriate FGF, FGFR1 elicits cellular responses such as proliferation, migration, and differentiation by activating a series of intracellular signaling pathways including Ras subfamily/ERK, PKC, phospholipase C/PI3K/AKT, Ip3-induced raising of cytosolic Ca2+, Ca2+/calmodulin-activated elements and pathways.. Studies have shown that mutations in FGFR1 are associated with Pfeiffer syndrome, Jackson-Weiss syndrome, Antley-Bixler syndrome, Osteoglobulin dysplasia, and autosomal dominant Kallmann syndrome2. And chromosomal aberrations involving FGFR1 are associated with stem cell myeloproliferative disorders and stem cell leukemia lymphoma syndrome. At the same time, FGFR1 also has a certain correlation with tumors (Table ...

We recently heard the Flash would be getting his own full-fledged pilot -- instead of a backdoor pilot piggybacking on Arrow -- and producer Andrew Kreisberg is here to explain why thats a good thing.. Well get to meet Grant Gustins version of Barry Allen (aka the future Flash) this week on Arrow, and producers had planned to introduce the concepts for a Flash spinoff with a backdoor pilot in episode 20 of Arrow next year. But the network has now decided to give Flash his own proper pilot episode (with a bigger budget), and Kreisberg says that should make things run a lot smoother.. He told TV Line that episode 20 will now be an episode of Arrow, which worked out well because the backdoor pilot concept had messed with the pacing, as [they] were going to have to take a right turn [from] where we were in our ongoing story to incorporate that. So a separate pilot should give Flashs universe room to breathe, without cramming it into the Arrow narrative.. But that doesnt mean weve seen the ...

Alternative (backdoor) androgen production and masculinization in the human fetus{{#pmid:30763313,PMID30763313}} Masculinization of the external genitalia in humans is dependent on formation of 5α-dihydrotestosterone (DHT) through both the canonical androgenic pathway and an alternative (backdoor) pathway. The fetal testes are essential for canonical androgen production, but little is known about the synthesis of backdoor androgens, despite their known critical role in masculinization. ...Results show that androsterone is the principal backdoor androgen in the male fetal circulation and that DHT is undetectable (,1 ng/mL), while in female fetuses, there are significantly lower levels of androsterone and testosterone. In the male, intermediates in the backdoor pathway are found primarily in the placenta and fetal liver, with significant androsterone levels also in the fetal adrenal. Backdoor intermediates, including androsterone, are only present at very low levels in the fetal testes. This ...

The MSA claim was male dog genitalia so, not having a Storeonce unit to look at, I went to have a look at the manuals on the hp public website. Took me five minutes of browsing to find out that the hpsupport account is discussed in the Storeonce B6000 user manuals (HP StoreOnce B6000 Series Backup System Maintenance &Service Guide, August 2012). It also has an hp internal link (page 13) to the website hp field engineers have to go to for the time-limited password generation tool for use after the password has been reset from the factory default at installation, which suggests to me that Technion has a unit where the install engineer did not reset the factory default password upon installation. Just like the MSA admin account non-story he goes on about. No wonder hp have been ignoring him.. The first moral of the story is only let accredited people that know what they are doing install your stuff. The second moral is dont rush to declare a built-in back door without doing at least five minutes ...

Confusingly, the Glieders and Fantibag Trojans are both known as Bagle downloader variants by other anti-virus vendors. Altogether its been an exceptionally busy week for new computer viruses. As well as the attack described by CA numerous new versions of the MyTob worm have also been produced. These variants typically pose as warnings from sys admins about the misuse of a potential victims email account with Subject lines such as *DETECTED* Online User Violation, Your Email Account is Suspended For Security Reasons and Account Alert.. When an infected attachment is launched, MyTob-CM (the most common of this weeks variants) attempts to turn off security applications. It also attempts to open a backdoor on infected Windows PC, allowing hackers to exploit compromised systems. Anti-virus firm Sophos reckons the creators of MyTob appear to be a group of virus writers called Hellbot. Carole Theriault, security consultant at Sophos, said similarities in code point to possible links between the ...
