Through the new techniques and establishment of novel protocols, especially in the field of molecular bio­lo­gy, together with the results from in vitro, in vivo pre­cli­ni­cal and clinical studies carried out on an im­pres­sive number of patients with various pathologies, scien­tists have established ample associations between the microbiome composition and certain cancers or the treat­ment response.

In some types of cancer, the role of microorganisms has been incriminated, which by their presence can activate certain signaling pathways or produce some metabolites that ultimately affect the cel­lular functioning. Category: DEFAULT Papillomavirus homme dermatologue For some microorganisms such as Fu­so­bac­te­rium nucleatum or toxigenic Bacteroides fragilis in colorectal cancer, the possible mechanisms of action have been already described.

Despite this fact, numerous stu­dies are still needed in order to determine whether bac­te­rial presence triggers the neoplastic process or the gut microbial abundance in affected patients is the hpv high risk serotypes of other changes taking place.

Keywords microbiome, carcinogenesis, diagnosis Rezumat În ultima perioadă, microbiomul a primit tot mai multă aten­ţie, fiind o temă de cercetare frecvent abordată în numeroase studii.

Microorganisms have been proven to be involved in the etiopathogenesis of some neoplasms 2. For example, Helicobacter pylori interacts through the cytotoxin-associated gene A CagA protein with E-cadherin, an intercellular adhesion molecule, leading to the dissociation of b-catenin from E-cadherin and thus to the cytoplasmic and nuclear accumulation of the first. Moreover, by prolonged activity of the vacuolating cytotoxin protein VacAmany alterations happen at endosomal, mitochondrial, permeability and signaling level 4leading to the impediment of autophagy 3.

Autophagy is a degradation process that involves the formation of autophagosomes, which include cytoplasmic components, and subsequently fuse with lysosomes, but due to the signals of mitochondrial destruction, the cell tries to reduce damage and triggers apoptosis instead of autophagy 5.

Oncoviruses also present many mechanisms by which they can be involved in carcinogenesis through two main paths: directly by genes insertion or indirectly by sustained inflammation hpv high risk serotypes.

For some types of cancers, parasitic etiologies have been suggested: Schistosoma haematobium, Schistosoma japonicum and Schistosoma mansoni through inflammation and oxidative stress; Opistorchis viverrini, Opistorchis felineus and Clonorchis sineses through inflammation, oxidative stress and cell proliferation 6. At the same time, the presence of hpv high risk serotypes parasites seems to have a beneficial, antineoplastic effect: Echinococcus spp.

The role of the microbiota has been highlighted in numerous molecular mechanisms of human body development, autoimmune diseases, hypersensitivity pathologies, and in many others, including neoplastic disorders 9. Recommendations Abstract Triploidy is a numerical chromosomal anomaly characterized by the presence of three sets of haploid chromosomes. The incidence is hard to evaluate, because usually it causes 1st trimester miscarriage.

The analysis of pathological cases identified in the last 11 years by prenatal diagnosis has shown that triploidies represented only 5. The karyotypes were recommended after discovering different congenital anomalies by ultrasound scan.

Colorectal cancer A. Microorganisms with procarcinogenic effect The involvement of microbiota in the carcinogenesis of colon and rectum has been explained through several hpv high risk serotypes, such as altering cell proliferation, influencing the immune system or metabolizing food factors.

Enterotoxigenic Bacteroides fragilis Bacteroides fragilis colonizes between 0.

So far, two strains have been identified: one toxigenic and the other one non-toxigenic The latter strain has beneficial effects in protective mechanisms against cancer 11while the first one, enterotoxigenic B. Hpv serotypes in head and neck cancer Oxiuri ciclu de viata This toxin promotes the cleavage of E-cadherin and leads to nuclear translocation of b-catenin and c-myc proto-oncogene transcription, resulting in colonic epithelial cells hyperplasia, increased spermine oxidase expression and reactive oxygen species production, which promote cell injury and carcinogenesis 1.

Another toxin-mediated mechanism is achieved with the implication of the immune system: the accumulation of regulatory T lymphocytes in the intestinal lamina propria, the suppression of mucosal immune response by T helper-1 lymphocytes, the increased interleukin IL secretion, ultimately leading to tumor genesis.

Fusobacterium nucleatum Fusobacterium nucleatum is an opportunistic anaerobic commensal of the oral cavity, which may be involved in the production of periodontal disease, but it can also cause diseases in other areas of the body, such as intrauterine infections with major pregnancy complications Recently, F. One of the virulence factors expressed on its surface is FadA, which exists in two forms: the intact form pre-FadAanchored in the membrane, hpv high risk serotypes the unguent de zinc pentru condiloame mature FadA mFadA.

Human papillomavirus hpv infection treatment - Papiloma humano se cura para siempre Human papillomavirus hpv infection treatment.

Human papilloma virus enfeksiyonu. Inflammatory cell type was determined using specific markers. The diagnosis of chronic rhinosinusitis with nasal polyps CRSwNP was made according to current EPOS guidelines based on hpv high risk serotypes history, clinical examination and nasal endoscopy. We examined surgically resected nasal polyps from patients diagnosed with CRSwNP, who benefited from surgical procedures at the Department of Otorhinolaryngology of our institution.

Only the pairing of the two forms represents an active complex the pre-FadA-mFadA complexwhich has the ability to attach to the endothelial cells through E-cadherin and activate signaling pathways through b-catenin This process leads to increased expression of transcription factors, oncogenes, inflammatory genes and stimulates the development of cancer cells Fusobacterium varum may also act through the same mechanism Several mechanisms have been proposed regarding the involvement of F.

This protein appears to be involved in the adhesion of tumor cells, which overexpress Gal-GalNAc molecules This process is followed by the interaction between F. When a Wnt ligand binds to the transmembrane domain of Frizzled proteins family of G protein-coupled receptor proteins and its coreceptors, low-density lipoprotein receptor hpv high risk serotypes protein 5 or 6 LRPthey form a complex together with the recruitment of the Dishevelled protein, which results in the phosphorylation and activation of LRP6.

Moreover, in the infection with F. Another possible involved mechanism is inflammation, with high levels of TNF-a and IL being observed in people with concurrent colonic adenomas and F. In those with colon cancer, increased levels of IL-6 and IL-8 have been noticed in the presence of F.

The presence of this bacterium has been associated with poor survival in patients with colon cancer and also with resistance to chemotherapy Escherichia coli Escherichia coli is a widespread Gram-negative bacterium, also part of the human gut microbiota. It is divi­ded into 5 phylogenetic groups, but the most commonly involved in human pathologies is the one belonging to B2 group The mechanism by which this leads to the development of colon cancer is not exactly known, but there hpv high risk serotypes two main pathways currently under investigation: one indirectly by inflammation and the other one directly through molecular mechanisms For example, hpv high risk serotypes adherent invasive E.

Hpv high risk serotypes, Human papillomavirus vaccine uses, Meniu de navigare Colibactin induces apoptosis of immune cells and chromosomal instability with DNA damage in the epithelial cells, leading to their senescence secretory phenotype of senescent cells Although the cells are no longer dividing, they may secrete growth factors which allow tumor development EspF may decrease the level of repair proteins MLH1 and MLH2 11 and it may also contribute to metastasis process by acting on the intercellular tight junction proteins occludin and claudin-1 Other proteins hpv high risk serotypes by E.

Salmonella spp.

Salmonella enterica comprises several serotypes, sirop oxiuri as Salmonella typhi, Salmonella paratyphi, Salmonella hpv high risk serotypes and Salmonella typhimurium In recent years, cancers of the colon, gall bladder and other cancers of the gastrointestinal tract have been correlated with infections caused by S. The mechanism of cancer transformation can also be direct and indirect, as in the case of other pathogens described There are two identified toxins responsible for these mechanisms: typhoid toxin a cyclomodulin similar hpv high risk serotypes the one produced by E.

Typhoid toxin can increase cell survival and promote intestinal dysbiosis AvrA hpv high risk serotypes been identified in the stool samples from colon cancer patients and several possible mechanisms of action have been suggested, including the inhibition of NF-kB signaling pathway, inhibition of IL, INF-g, TNF-a secretion, IL-6 transcription and stimulation of IL transcription By its activity of acetyl transferase, AvrA can affect p53 activity, decreasing apoptosis It has been observed that the higher incidence of gallbladder cancer in some geographical areas corresponds to the increased incidence of Salmonella spp.

Implicaţiile microbiomului în iniţierea şi promovarea carcinogenezei Enterococcus faecalis By producing increased amounts of superoxide at the luminal level of the colonic mucosa, Enterococcus faecalis can lead to DNA damage, point mutations 2chromosome instability and cellular aneuploidy 1. In vitro studies have proven that E. However, some studies even suggest a possible protective role of E. Streptococcus gallolyticus Streptococcus gallolyticus formerly known as S.

Although frequently reported, the mechanism of action is not yet fully elucidated, but carcinogenic hpv high risk serotypes is most likely produced by inflammatory effects In vitro studies have shown that mucosal exposure to this bacterium hpv high risk serotypes to increased IL-1 16but also IL-8, the latter being involved in carcinogenesis processes by increasing oxidative stress, promoting angiogenesis, tumor proliferation and overexpression of COX-2 Another recent theory mentions the ability of S.

In this case, it acts by activating the Wnt pathway, then decreasing Slc10A2 protein production Solute Carrier Family 10 Member 2, a bile acid transporterwhich leads tratamentul negi plantare the accumulation of bile acids.

Moreover, bacteriocine production is activated, allowing S. Clostridium septicum Due to its ability to produce alpha-toxin that binds to GPI glycosylphosphatidylinositol receptors on the cell surface, including folate receptors, Clostridium septicum has been associated in some studies with carcinogenesis Microorganisms with possible protective effect Some studies have pointed out that certain bacteria may play a protective role in neoplastic processes through numerous mechanisms, including the production of short-chain fatty acids 1.

They are produced in the intestine by microbial fermentation of the dietary fibres, representing the primary energy source for the colon epithelial cells, as opposed hpv high risk serotypes the cancer cells, which are based on carbon source metabolism, especially on glucose 1.

Eubacterium hpv high risk serotypes and Faecalibacterium prausnitzii may be involved in the butyrate production, having an anti-inflammatory role by inducing IL expression Furthermore, the intracellular increased level of butyrate concentration may act as an inhibitor of histone deacetylation, which stimulates apoptosis and inhibits cell proliferation 1.

Through their components, probiotics may have implications in modulating the immune system. For example, the lipopolysaccharide from the bacterial membrane of Gram-negative bacteria may activate the TLR4 surface receptor, which stimulates the T-cell-mediated immune response against cancer cells Bifidobacterium, Bacteroides thetaiotamicron and non-toxigenic B.
