One of the mechanisms by which CELL DEATH occurs (compare with NECROSIS and AUTOPHAGOCYTOSIS). Apoptosis is the mechanism responsible for the physiological deletion of cells and appears to be intrinsically programmed. It is characterized by distinctive morphologic changes in the nucleus and cytoplasm, chromatin cleavage at regularly spaced sites, and the endonucleolytic cleavage of genomic DNA; (DNA FRAGMENTATION); at internucleosomal sites. This mode of cell death serves as a balance to mitosis in regulating the size of animal tissues and in mediating pathologic processes associated with tumor growth.
A family of intracellular CYSTEINE ENDOPEPTIDASES that play a role in regulating INFLAMMATION and APOPTOSIS. They specifically cleave peptides at a CYSTEINE amino acid that follows an ASPARTIC ACID residue. Caspases are activated by proteolytic cleavage of a precursor form to yield large and small subunits that form the enzyme. Since the cleavage site within precursors matches the specificity of caspases, sequential activation of precursors by activated caspases can occur.

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.

Subcellular distribution and redistribution of Bcl-2 family proteins in human leukemia cells undergoing apoptosis. (1/660)

It has been suggested that the ratio of Bcl-2 family proapoptotic proteins to antiapoptotic proteins determines the sensitivity of leukemic cells to apoptosis. However, it is believed that Bcl-2 family proteins exert their function on apoptosis only when they target to the mitochondrial outer membrane. The vinblastine-resistant T-lymphoblastic leukemic cell line CEM/VLB100 has increased sensitivity to tumor necrosis factor-alpha (TNF-alpha)-induced cytochrome c release, mitochondrial respiratory inhibition, and consequently apoptosis, compared with parental CEM cells. However, there was no difference between the two cell lines in the expression of Bcl-2 family proteins Bcl-2, Bcl-XL, Bcl-XS, Bad, and Bax at the whole cell level, as analyzed by Western blotting. Bcl-2 mainly located to mitochondria and light membrane as a membrane-bound protein, whereas Bcl-XL was located in both mitochondria and cytosol. Similar levels of both Bcl-2 and Bcl-XL were present in the resting mitochondria of the two cell lines. Although the proapoptotic proteins Bcl-XS, Bad, and Bax were mainly located in the cytosol, CEM/VLB100 mitochondria expressed higher levels of these proapoptotic proteins. Subcellular redistribution of the Bcl-2 family proteins was detected in a cell-free system by both Western blotting and flow cytometry after exposure to TNF-alpha. The levels of Bcl-2 family proteins were not altered at the whole cell level by TNF-alpha. However, after exposure to TNF-alpha, Bax, Bad, and Bcl-XS translocated from the cytosol to the mitochondria of both cell lines. An increase in Bcl-2 levels was observed in CEM mitochondria, which showed resistance to TNF-alpha-induced cytochrome c release. By contrast, decreased mitochondrial Bcl-2 was observed in CEM/VLB100 cells, which released cytochrome c from the mitochondria and underwent apoptosis as detected by fluorescence microscopy. We conclude that mitochondrial levels of Bcl-2 family proteins may determine the sensitivity of leukemic cells to apoptosis and that, furthermore, these levels may change rapidly after exposure of cells to toxic stimuli.  (+info)

Dissociation of apoptosis from proliferation, protein kinase B activation, and BAD phosphorylation in interleukin-3-mediated phosphoinositide 3-kinase signaling. (2/660)

Interleukin-3 (IL-3) acts as both a growth and survival factor for many hemopoietic cells. IL-3 treatment of responsive cells leads to the rapid and transient activation of Class IA phosphoinositide-3-kinases (PI3Ks) and the serine/threonine kinase Akt/protein kinase B (PKB) and phosphorylation of BAD. Each of these molecules has been implicated in anti-apoptotic signaling in a wide range of cells. Using regulated expression of dominant-negative p85 (Deltap85) in stably transfected IL-3-dependent BaF/3 cells, we have specifically investigated the role of class IA PI3K in IL-3 signaling. The major functional consequence of Deltap85 expression in these cells is a highly reproducible, dramatic reduction in IL-3-induced proliferation. Expression of Deltap85 reduces IL-3-induced PKB phosphorylation and activation and phosphorylation of BAD dramatically, to levels seen in unstimulated cells. Despite these reductions, the levels of apoptosis observed in the same cells are very low and do not account for the reduction in IL-3-dependent proliferation we observe. These results show that Deltap85 inhibits both PKB activity and BAD phosphorylation without significantly affecting levels of apoptosis, suggesting that there are targets other than PKB and BAD that can transmit survival signals in these cells. Our data indicate that the prime target for PI3K action in IL-3 signaling is at the level of regulation of proliferation.  (+info)

Ca2+-induced apoptosis through calcineurin dephosphorylation of BAD. (3/660)

The Ca2+-activated protein phosphatase calcineurin induces apoptosis, but the mechanism is unknown. Calcineurin was found to dephosphorylate BAD, a pro-apoptotic member of the Bcl-2 family, thus enhancing BAD heterodimerization with Bcl-xL and promoting apoptosis. The Ca2+-induced dephosphorylation of BAD correlated with its dissociation from 14-3-3 in the cytosol and translocation to mitochondria where Bcl-xL resides. In hippocampal neurons, L-glutamate, an inducer of Ca2+ influx and calcineurin activation, triggered mitochondrial targeting of BAD and apoptosis, which were both suppressible by coexpression of a dominant-inhibitory mutant of calcineurin or pharmacological inhibitors of this phosphatase. Thus, a Ca2+-inducible mechanism for apoptosis induction operates by regulating BAD phosphorylation and localization in cells.  (+info)

Trophic support promotes survival of bcl-x-deficient telencephalic cells in vitro. (4/660)

Survival of immature neurons is regulated by Bcl-xL, as targeted disruption of bcl-x significantly increases cell death in vivo and in vitro. Death of cultured bcl-x-deficient and wild-type telencephalic cells can be prevented by fetal calf serum or chemically-defined medium (ITS), suggesting trophic factors in these media potentiate survival through a pathway independent of Bcl-xL. Addition of trophic factors to basal medium revealed that insulin and insulin-like growth factors (IGFs), but not other trophic factors, reduced apoptosis of wild-type and bcl-x-deficient telencephalic cells. Antibodies raised against IGF-I receptors and wortmannin both attenuated the effects of IGF-I, indicating survival was mediated by IGF-I receptors and phosphatidylinositol 3'-kinase signaling, whereas effects of ITS were only partially reduced by these agents. The survival promoting effects of ITS were reduced in cells lacking both bcl-x and bcl-2, indicating Bcl-2 plays a supportive role to Bcl-xL in maintaining telencephalic cell survival. Furthermore, the ratio of expression of the pro-apoptotic bax gene to the anti-apoptotic bcl-2 gene was reduced in bcl-x-deficient cultures grown in ITS, suggesting that the interaction between these bcl-2 family members may, in part, regulate a Bcl-xL independent survival pathway. Finally, the pro-apoptotic bad gene does not appear to play a role in these interactions as targeted disruption of bad did not alter apoptosis in telencephalic cultures.  (+info)

Phosphorylation and inactivation of BAD by mitochondria-anchored protein kinase A. (5/660)

Signaling pathways between cell surface receptors and the BCL-2 family of proteins regulate cell death. Survival factors induce the phosphorylation and inactivation of BAD, a proapoptotic member. Purification of BAD kinase(s) identified membrane-based cAMP-dependent protein kinase (PKA) as a BAD Ser-112 (S112) site-specific kinase. PKA-specific inhibitors blocked the IL-3-induced phosphorylation on S112 of endogenous BAD as well as mitochondria-based BAD S112 kinase activity. A blocking peptide that disrupts type II PKA holoenzyme association with A-kinase-anchoring proteins (AKAPs) also inhibited BAD phosphorylation and eliminated the BAD S112 kinase activity at mitochondria. Thus, the anchoring of PKA to mitochondria represents a focused subcellular kinase/substrate interaction that inactivates BAD at its target organelle in response to a survival factor.  (+info)

Developmental regulation of Bcl-2 family protein expression in the involuting mammary gland. (6/660)

Epithelial cells within the mammary gland undergo developmental programmes of proliferation and apoptosis during the pregnancy cycle. After weaning, secretory epithelial cells are removed by apoptosis. To determine whether members of the Bcl-2 gene family could be involved in regulating this process, we have examined whether changes in their expression occur during this developmental apoptotic program in vivo. Bax and Bcl-x were evenly expressed throughout development. However, expression of Bak and Bad was increased during late pregnancy and lactation, and the proteins were present during the time of maximal apoptotic involution. Thereafter, their levels declined. In contrast, Bcl-w was expressed in pregnancy and lactation but was downregulated at the onset of apoptosis. Bcl-2 was not detected in lactating or early involuting mammary gland. Thus, the pro-apoptotic proteins Bax, Bak and Bad, as well as the death-suppressors Bcl-x, Bcl-2 and Bcl-w, are synthesised in mouse mammary gland, and dynamic changes in the expression profiles of these proteins occurs during development. To determine if changes in Bak and Bcl-w expression could regulate mammary apoptosis, their effect on cultured mouse mammary epithelial cells was examined in transient transfection assays. Enforced expression of Bak induced rapid mammary apoptosis, which could be suppressed by coexpression of Bcl-w. In extracts of mammary tissue in vivo, Bak heterodimerized with Bcl-x whereas Bax associated with Bcl-w, but Bak/Bcl-w heterodimers were not detected. Thus, Bak and Bcl-w may regulate cell death through independent pathways. These results support a model in which mammary epithelial cells are primed for apoptosis during the transition from pregnancy to lactation by de novo expression of the death effectors Bak and Bad. It is suggested that these proteins are prevented from triggering apoptosis by anti-apoptotic Bcl-2 family proteins until involution, when the levels of Bcl-w decline. Our study provides evidence that regulated changes in the expression of cell death genes may contribute to the developmental control of mammary apoptosis.  (+info)

Phosphorylation of the transcription factor forkhead family member FKHR by protein kinase B. (7/660)

Protein kinase B lies "downstream" of phosphatidylinositide (PtdIns) 3-kinase and is thought to mediate many of the intracellular actions of insulin and other growth factors. Here we show that FKHR, a human homologue of the DAF16 transcription factor in Caenorhabditis elegans, is rapidly phosphorylated by human protein kinase Balpha (PKBalpha) at Thr-24, Ser-256, and Ser-319 in vitro and at a much faster rate than BAD, which is thought to be a physiological substrate for PKB. The same three sites, which all lie in the canonical PKB consensus sequences (Arg-Xaa-Arg-Xaa-Xaa-(Ser/Thr)), became phosphorylated when FKHR was cotransfected with either PKB or PDK1 (an upstream activator of PKB). All three residues became phosphorylated when 293 cells were stimulated with insulin-like growth factor 1 (IGF-1). The IGF-1-induced phosphorylation was abolished by the PtdIns 3-kinase inhibitor wortmannin but not by PD 98059 (an inhibitor of the mitogen-activated protein kinase cascade) or by rapamycin. These results indicate that FKHR is a physiological substrate of PKB and that it may mediate some of the physiological effects of PKB on gene expression. DAF16 is known to be a component of a signaling pathway that has been partially dissected genetically and includes homologues of the insulin/IGF-1 receptor, PtdIns 3-kinase and PKB. The conservation of Thr-24, Ser-256, and Ser-319 and the sequences surrounding them in DAF16 therefore suggests that DAF16 is also a direct substrate for PKB in C. elegans.  (+info)

Cytokine-induced protein kinase B activation and Bad phosphorylation do not correlate with cell survival of hemopoietic cells. (8/660)

Activation of phosphoinositide-3 kinases (PI3Ks), their downstream target protein kinase B (PKB), and phosphorylation of Bad have all been implicated in survival signaling in many systems. However, it is not known whether these events are sufficient or necessary to universally prevent apoptosis. To address this issue, we have used three different factor-dependent hemopoietic cell lines, MC/9, BaF/3, and factor-dependent (FD)-6, which respond to a range of cytokines, to investigate the relationship between PI3K, PKB, and Bad activity with survival. The cytokines IL-3, IL-4, stem cell factor (SCF), GM-CSF, and insulin all induced the rapid and transient activation of PKB in responsive cell lines. In all cases, cytokine-induced PKB activation was sensitive to inhibition by the PI3K inhibitor, LY294002. However, dual phosphorylation of the proapoptotic protein Bad was found not to correlate with PKB activation. In addition, we observed cell-type-specific differences in the ability of the same cytokine to induce Bad phosphorylation. Whereas IL-4 induced low levels of dual phosphorylation of Bad in FD-6, it was unable to in MC/9 or BaF/3. Insulin, which was the most potent inducer of PKB in FD-6, induced barely detectable Bad phosphorylation. In addition, the ability of a particular cytokine to induce PKB activity did not correlate with its ability to promote cell survival and/or proliferation. These data demonstrate that, in hemopoietic cells, activation of PKB does not automatically confer a survival signal or result in phosphorylation of Bad, implying that other survival pathways must be involved.  (+info)

The BH3-only protein Bad is a proapoptotic Bcl-2 family member that acts as a sensitizer in intrinsic apoptosis by inactivating antiapoptotic members through heterodimer formation. Bad has been shown to contribute to tumorigenesis, including lymphoma formation in humans and mice, through alteration in expression or functional status. Here, its immunohistochemical expression was analyzed in canine nonneoplastic and lymphoma tissues using tissue microarrays. Bad was expressed in the cytoplasm of a wide range of nonneoplastic tissues, especially epithelial cells. Nonneoplastic lymph nodes displayed weak immunostaining in the follicular germinal centers only. Immunoblotting supported these observations but also revealed presence of nonspecific labeling in some organs. Of 81 lymphomas, 29 (35.8%) displayed moderate to strong immunohistochemical Bad labeling, and a significant expression increase was found in lymphomas (especially B cell and double negative) compared to nonneoplastic lymph nodes. ...
MEK-1ca did inhibit BAD-mediated apoptosis in cultures that were exposed to IGF-1 (Fig. 3A). In the absence of MEK-1ca expression, IGF-1 reduced the apoptotic effect of BAD in cerebellar granule neurons, albeit to a lesser extent than that achieved by the combination of MEK-1ca expression and IGF-1 receptor activation (Fig. 3A). Because IGF-1 inhibits the apoptotic effect of BAD by inducing the phosphorylation of BAD at Ser136(20), our results raise the possibility that MAPK suppression of BAD-mediated cell death requires that BAD be phosphorylated at Ser136. Consistent with this possibility, in IGF-1-treated cerebellar granule neurons MEK-1ca failed to inhibit the apoptotic effect of a BAD protein in which Ser136 was converted to Ala (16). Together, these results suggest that the MAPK and PI-3K-Akt signaling pathways converge at BAD to suppress the apoptotic effect of BAD.. We next examined the ability of the MAPK signaling pathway to inhibit the apoptotic effect of a BAD mutant in which Ser112 ...

These results indicate that the mechanism by which the US3 protein kinase blocks activation of the BAD protein does not depend on the phosphorylation of the regulatory serines or the interaction of BAD with the 14-3-3 proteins.. In an earlier article this laboratory reported that the US3 protein kinase blocked the apoptosis induced by the HSV-1 d120 mutant at a premitochondrial stage (21). Further studies revealed that the kinase also blocks programmed cell death induced by the proapoptotic protein BAD (22). In the studies reported here, we investigated the effects of the US3 protein kinase on the function and state of the BAD protein. We report several key findings below.. (i) In uninfected cells BAD was processed by at least two proteolytic cleavages that are blocked by caspase inhibitors. The untreated transduced cells expressed elevated caspase 3 activity.. (ii) In cells cotransduced with the US3 protein kinase, the BAD protein was not cleaved and the caspase 3 activity was not ...

Simple lifestyle choices, such as following a healthy diet and regular exercise, can override bad genes, according to one of Canadas leading genetic researchers.
The sensitivity of tumor cells to apoptosis determines their ability to escape cytotoxic therapies (1, 2, 3) and to survive under adverse physiological circumstances, such as reduced oxygen (4, 5, 6) and sites of metastasis (7) . Recently, a survival-regulating signal transduction pathway has been identified that is important in determining sensitivity to apoptosis in neural (8, 9, 10) , fibroblastic (11, 12, 13) , epithelial (11 , 14) , and hematopoietic cells (15) . This pathway, which is engaged by several survival factors such as IGF 3 -I and interleukin 3, involves, sequentially, the activation of PI3 kinase, the production of 3′-phosphoinositides, activation and recruitment of phospholipid-dependent kinases, and their phosphorylation of the protein kinase Akt/PKB on serine 473 and threonine 308 (11 , 16, 17, 18, 19) . Phosphorylation on these sites activates Akt/PKB, which then inhibits apoptosis by phosphorylation and inactivation of the proapoptotic proteins BAD (20 , 21) , Caspase 9 ...

We have shown that the expression of a number of protective genes and a protective pathway culminating in Bad phosphorylation are increased in mice that overexpress APPSw and have no neuronal loss. Increased levels of IGF-2 mRNA and protein correspond to increased activation of the IGF-1 receptor, activation of Akt and Erk1/2, and phosphorylation of Bad in APPSw mice. The increased expression of TTR and IGF-2 as well as increased phospho-Bad staining in hippocampal neurons was consistent in both preplaque (6 months) and postplaque (12 months) Tg2576 mice. Other conditions, such as the presence of a human tau gene, may be necessary for complete AD pathology. However, taken together, these data imply that the lack of neurodegeneration in APPSw mice is a result of the activation of known cell survival pathways associated with the overexpression of APPSw.. Transthyretin has been shown to bind Aβ and inhibit Aβ aggregation (Schwarzman et al., 1994). In human AD patients the concentration of TTR is ...
The fact is, genetics are a tendency, not a death sentence. Genes for heart disease, breast cancer, mental, emotional disorders, etc., are like the trigger on a gun-theyre only dangerous if you pull them. Inside of just one nucleus in one of your fifty trillion cells is six feet of DNA material. This is similar to cramming thirty miles of wire into a cherry pit. This DNA comes in forty-six different sections called chromosomes, which is subdivided into your genes. These genes encode information for molecules that perform a bewildering number of functions. We barely have a glimpse of the monstrous complexity of genes and how they specifically affect our behaviors and respective biology. To say that a gene causes obesity, depression, alcoholism, or chocolate addiction is insane. We truly dont understand 5 percent of whats going on, and that percentage never improves because with each new discovery, we also discover that theres even more mystery.. ...

A much-celebrated performer of my acquaintance received an unfortunate review in a major paper last year. Lets say that this performer is an actress, in Toronto, and lets say it was the Toronto Star. I found the review unfair-my personal opinion was that her show was brilliant-but I was stunned by her response. A day or two after the review came out, she sent the Star reviewer a long email.. She told the reviewer he was full of shit, made various vague statements that a reasonable person might interpret as a threat (I guess I was due for a hatchet job from the Star given all the praise Ive received over the years, going all the way back to my debut solo show Toronto Star Theatre Critic Found at Bottom of River), suggested that the reviewer was racist-it happened that the actress and critic were of different races-hit send, and then forwarded it to her email list. Fortunately for her career, no one sent it to Gawker.. The day after the most recent and more vicious of my Publishers ...

Sexuality and Evolution According to a study in the Oct. 19 issue of Science, sex may be a way for you to bring in the good and get rid of the bad. In other words, sex weeds out the bad genes that may have arisen in your DNA -- so-called baggage -- and allows good mutations to flourish in your offspring. To test this interesting theory, researchers William R. Rice, PhD, and Adam K. Chippendale looked at two different populations of fruit flies -- one that reproduced with sex and one reproduced without sex. Rice and Chippendale are from the department of ecology, evolution and marine biology at the University of California in Santa Barbara. They found that in flies that had sex, good gene changes were able to spread throughout the population faster than those deprived of the joy of sex. Generally, we think of mutations as being a bad thing, but, in fact, mutations can actually lead to good changes in our bodies. For example, at some point in history, a good gene mutation likely led to some ...

If some gene is harmuful when you are 80 years old (e.g. something that causes cancer), it doesnt mean it is exclusively a bad gene. Many oncogenes, for example, are genetic control elements that have an important role in the life and development of an individual. If you removed them, you would die as a fetus. So can you really call a gene that allows you to become an adult and have children a harmful gene? It may become harmful later on for sure, but it has already done its good deeds. Also it is worth noting that often these harmful genes have simply mutated during the individuals life and become malfunctioning. Evolutionary it is not very disastrous if you die of cancer at the age of 80, if the gene that caused your death was useful the years before that ...

PP-2B inhibition by thioureylenes resulted in a repression of NFAT-dependent gene transcription and thus might influence long-term apoptotic events by limiting the expression of proapoptotic genes (Holtz-Heppelmann et al., 1998). However, NMDA receptor activation, disruption of calcium homeostasis, and PP-2B activation is most probably associated with rapid cell death initiated by proapoptotic Bad proteins (Wang et al., 1999). Thioureylenes inhibited PP-2B-dependent Bad dephosphorylation and the subsequent initiation of the intrinsic pathway of apoptosis (Yang et al., 1995). Thus, caspase-3 activity, cleavage of the cellular caspase-3 substrate PARP, and caspase-3-dependent cell death were inhibited in SK-N-SH cells and organotypic hippocampal slice cultures. These events depended on active PP-2B activation, as demonstrated by coincubation with CsA, a specific PP-2B inhibitor, and included the repression of procaspase-3 processing.. Our results suggest that thioureylenes also attenuate ...
PIM1_HUMAN] Proto-oncogene with serine/threonine kinase activity involved in cell survival and cell proliferation and thus providing a selective advantage in tumorigenesis. Exerts its oncogenic activity through: the regulation of MYC transcriptional activity, the regulation of cell cycle progression and by phosphorylation and inhibition of proapoptotic proteins (BAD, MAP3K5, FOXO3). Phosphorylation of MYC leads to an increase of MYC protein stability and thereby an increase of transcriptional activity. The stabilization of MYC exerted by PIM1 might explain partly the strong synergism between these two oncogenes in tumorigenesis. Mediates survival signaling through phosphorylation of BAD, which induces release of the anti-apoptotic protein Bcl-X(L)/BCL2L1. Phosphorylation of MAP3K5, an other proapoptotic protein, by PIM1, significantly decreases MAP3K5 kinase activity and inhibits MAP3K5-mediated phosphorylation of JNK and JNK/p38MAPK subsequently reducing caspase-3 activation and cell apoptosis. ...
In the popular Pixar Movie Inside Out, the emotion, Joy, says [Anger] cares very deeply about things being fair. This becomes apparent when Riley-the protagonist in the film and whose emotions are heavily involved in her decisions-has a difficult time moving to a new city. Anger (pictured above) is first to assume authority and advocates for her to run away! In this impatient and impulsive move, Anger is responsible for Riley stealing her mothers credit card, lying to her parents, and running away from home. Although Riley eventually returns home when Joy and Sadness take control, it is clear that Anger was responsible for a majority of the bad decisions made in the film as he offers little constructive help. There certainly is some truth behind these bad expressions of anger. For instance, research has linked anger with the potential for: (i) aggression and violence; (ii) interpersonal conflicts such as organizational disputes and domestic violence; (iii) impaired judgment, which increases ...

The researchers used their AWSEM (Associative memory, Water-mediated Structure and Energy Model) program to analyze how computer models of muscle proteins interact with each other, particularly in various temperatures that determine when a protein is likely to fold or unfold.. The program relies on Wolynes groundbreaking principle of minimal frustration to determine how the energy associated with amino acids, bead-like elements in a monomer chain, determines their interactions with their neighbors as the chain folds into a useful protein.. Proteins usually fold and unfold many times as they carry out their tasks, and each cycle is an opportunity for it to misfold. When that happens, the body generally destroys and discards the useless protein. But when that process fails, misfolded proteins can form the gummy amyloid plaques often found in the brains of Alzheimers patients.. The titin proteins the Rice team chose to study are not implicated in disease but have been well-characterized by ...

Tissue from my tumor will be tested (provided insurance agrees to pay for it!) to find out if there are certain markers that will tell us if it is something I inherited. If nothing shows up in the tumor, then there is a different test I can have done that will tell me whether I have this other inherited condition where I get 1 bad gene from each parent. People can be carriers of this gene and not get cancer themselves, but if a child gets 1 from each parent, then that child is likely to get colon cancer. With one of these issues there is a greater chance that I could get other kinds of cancers also, specifically uterine. I guess some women even have their uterus removed to prevent this. So, it would be good to know for myself, and my daughters. ...
A gene is a locatable region of genomic sequence, corresponding to a unit of inheritance, which is associated with regulatory regions, transcribed regions and/or other functional sequence regions.[1][2] The physical development and phenotype of organisms can be thought of as a product of genes interacting with each other and with the environment.[3] A concise definition of a gene, taking into account complex patterns of regulation and transcription, genic conservation and non-coding RNA genes, has been proposed by Gerstein et al.[4] A gene is a union of genomic sequences encoding a coherent set of potentially overlapping functional products. Colloquially, the term gene is often used to refer to an inheritable trait which is usually accompanied by a phenotype as in (tall genes or bad genes) -- the proper scientific term for this is allele. In cells, genes consist of a long strand of DNA that contains a promoter, which controls the activity of a gene, and coding and non-coding sequence. ...

A fundamental concern about applying gene editing to human embryos is how to limit the risk of errors, or off-target effects. One makes an edit to change a bad genes defect, and presumably prevent the disease the defective gene would cause. But the current methods to do that, although apparently highly selective, might still make other, unwanted changes as well-with possible deleterious, even disastrous, consequences.. Heretofore, the attention to these off-target effects has largely been directed to changes in genes that are separated from the target gene. However, a recent news item in Nature describes three recent experiments with human embryos in the laboratory, in which large defects were induced in the chromosomes bearing the target gene-that is, right next door. The difference is a bit like the difference between damage by shrapnel (distant effect) and blowing a 6-foot hole instead of a pinhole (near effect). The latter is now the new concern. Apparently, and, for one who does not ...

Adverse criticism, far from being the easiest, is one of the hardest things in the world to do well. And that for two reasons. When we try to define the badness of a work, we usually end by calling it bad on the strength of characteristics we can find also in good work. . . . The novel before you is bad-a transparent compensatory fantasy projected by a poor, plain woman, erotically starving. Yes, but so is Jane Eyre. . . . An author betrays shocking indifference to all the great political, social, and intellectuals upheavals of his age; like Jane Austen. The solution of the problem is, I suspect, still far away. . . . The other difficulty lies within. . . . Reviews filled with venom have often been condemned socially for their bad manners, or ethically for their spite. I am not prepared to defend them from either charge; but I prefer to stress their inutility. . . . Automatically, without thinking about it ones mind discounts everything [the venomous critic] says, as it does when we are ...

I took a Diflucan on the same day that I started to feel these symptoms, so now I feel better, but I am just wondering if this has happened to anyone else.

I went to visit my pals on Saturday, Kristy, Stacy, Ryan, and Craig. It was, of course, fabulous, and I am seriously aggravated with myself for not taking any pictures. I even remembered my camera this time. How like me. (To forget to take pictures after making sure to remember the camera. Oh geez.) I had to drive a new route there, because obviously Ive never gone there from here before. That was a trick and a half, let me tell you. It took me on all these little roads in the middle of nowhere, roads that werent even county roads. None were labeled. I was a mess, I can assure you. So, I had Chuck find me a better way home. The way he had me go took a little longer, but I was able to stay on actual roads with names. This helped a lot, as it was dark and snowing at this point. Oh, and it saved my life. Apparently, it was really bad on 74 just before I got to it. When I made it onto 74, traffic was crawling (people averaging 35 mph.) I saw two cars that had flipped over, and I lost count of all ...
But I was making a big mistake. I had kept hearing that its simple, what you take in needs to match what you put out, plus some. So if you eat big meals, but dont exercise, that food has got to go somewhere, like on your frame, probably as fat. Im not a big fan of carrying around extra fat. I mean, why? Right? What do you need it for, other than to rationalize why you dont have to work to get rid of it? Fat isnt attractive, its bad on your body, your joints, your self-esteem, and the nations infrastructure to be honest. Airplanes dont need to carry our lard around, wasting fuel, adding to carbon emissions. Cars dont need to be lugging around our bulk, wearing them out slowly along with our roads and bridges. We are costing our nation a lot of money year in and year out with all the unnecessary fat we are carrying about. So, why not lose it? You may even live longer ...

It has been a long and stressful past few days, but I am finally back in my own house with my own noises and my own foods. Actually, the past few days werent really that bad at all. The worst day was yesterday. Yesterday morning, around 4 A.M., I woke up and decided that I was going to be sick. So my feet carried me to the toilet, and up came whatever small dinner I had had earlier. Pleasant. My nurse came and brought me some anti-nausea medication called Ativan, which is one of the really heavy duty ones. Basically, it knocked me out for the rest of the day. I threw up two more times throughout the morning, but they put more medication in me, as well as more chemo, and I literally slept all day. So like I said, now Im home. I dont feel great; I have certainly had better days, but Im glad to be out of the hospital. Im currently working through a little bit of nausea and a fair amount of tiredness, but Im sure Ill be back to happy after a good dinner and a good nights sleep. It is ...

I got some 2XU Knee-High compression socks because my friend (who suffered from severe calf cramping regularly) recommended the things to me because I tend to cramp bad at the end of long distances. I must admit - I was very skeptical at first, but my first 60 miler after taking 2 months off - I had no cramping. Now - after the same exact ride - I took off the sock - and the moment the compression fell off of my calves - a severe cramp came on. I have been continuing the use of it and its very simple for me - I cramp on the rides I do not have them on - and I dont cramp when I do have them on ...
