In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Question: Context: Aedes aegypti is the main mosquito vector of the four serotypes of dengue virus (DENV). Previous population genetic and vector competence studies have demonstrated substantial genetic structure and major differences in the ability to transmit dengue viruses in Ae. aegypti populations in Mexico.', 'Population genetic studies revealed that the intersection of the Neovolcanic axis (NVA) with the Gulf of Mexico coast in the state of Veracruz acts as a discrete barrier to gene flow among Ae. aegypti populations north and south of the NVA. The mosquito populations north and south of the NVA also differed in their vector competence (VC) for dengue serotype 2 virus (DENV2). The average VC rate for Ae. aegypti mosquitoes from populations from north of the NVA was 0.55; in contrast the average VC rate for mosquitoes from populations from south of the NVA was 0.20. Most of this variation was attributable to a midgut infection and escape barriers. In Ae. aegypti north of the NVA 21.5% failed to develop midgut infections and 30.3% of those with an infected midgut failed to develop a disseminated infection. In contrast, south of the NVA 45.2% failed to develop midgut infections and 62.8% of those with an infected midgut failed to develop a disseminated infection.\Question: Is the neovolcanic axis a barrier to gene flow among Aedes aegypti populations in Mexico that differ in vector competence for Dengue 2 virus?

Answer: Barriers to gene flow in vector populations may also impact the frequency of genes that condition continuous and epidemiologically relevant traits such as vector competence. Further studies are warranted to determine why the NVA is a barrier to gene flow and to determine whether the differences in vector competence seen north and south of the NVA are stable and epidemiologically significant.

Question: Context: Due to lack of a targeted therapy for the triple-negative breast cancer (TNBC) patients, it is important to explore this aggressive breast cancer type in more detail and to establish novel therapeutic approaches. TNBC is defined negative for the protein expression of oestrogen receptor (ER), progesterone receptor (PR) and human epidermal growth factor receptor 2 (HER2). One prominent feature of this cancer type is the frequent overexpression of major components of the urokinase-type plasminogen activator system (uPAS) including uPA, its receptor uPAR and the inhibitor PAI-1, which may be valuable as therapeutic targets.', 'Direct interactions of uPAR with interactors were demonstrated by immunoprecipitations and proximity ligation assays. For stable knockdowns of target proteins, lentiviral vectors were used and the effects were analysed by immunoblottings and using in vitro cell viability, migration and invasion assays. Immunohistochemical and statistical analyses of biomarkers and clinical parameters were conducted in a TNBC cohort (n=174).', 'Direct tumour-promoting interactions of uPAR with uPA and the insulin-like growth factor receptor 1 (IGF1R) were shown in TNBC cells and these interactions were significantly reduced (p=0.001) when uPAR was downregulated. The combined knockdown of uPAR and uPA or IGF1R additively and significantly reduced cell viability, migration and invasion of the model cell lines. In TNBC tissue, the complexes formed by uPAR with uPA or with IGF1R significantly correlated with the histological grade (p=0.0019) as well as with cathepsin B and D (p0.0001) that are implicated in cell invasion and metastasis.\Question: Does uPAR enhance malignant potential of triple-negative breast cancer by directly interacting with uPA and IGF1R?

Answer: Our outcomes show that not only overexpressed biomarkers promote tumourigenesis, but rather their interactions further potentiate tumour progression. This study emphasises the potential of combined approaches targeting uPAR and its interactors with regard to an improved therapy of TNBC.

Question: Context: A disintegrin and metalloprotease 12 (ADAM12) has multiple domains and functions, and it plays important roles in the development of cancer. We conducted a retrospective study to determine whether the expression of the membrane type of ADAM12 (ADAM12-L) could be a prognostic factor in resected pathological (p-) stage I lung adenocarcinoma.', 'ADAM12-L mRNA expression was quantified by a reverse-transcription polymerase chain reaction in tissue samples from 84 completely resected p-stage I lung adenocarcinoma patients. The patients were divided into ADAM12-L-Low and ADAM12-L-High groups, and correlations with clinicopathologic features were obtained.', 'Five-year survival rates of the ADAM12-L-Low and ADAM12-L-High groups were 95.1% and 71.9%, respectively. The postoperative prognosis for the ADAM12-L-High group was significantly poorer than for the ADAM12-L-Low group (P = 0.006). Multivariate analysis confirmed that high expression of ADAM12-L was an independent factor for poor prognosis (P = 0.007, hazard ratio 8.288). The ADAM12-L-High group was less differentiated and had a significantly higher rate of cancer recurrence.\Question: Is a disintegrin and metalloprotease 12 ( ADAM12 ) a prognostic factor in resected pathological stage I lung adenocarcinoma?

Answer:
ADAM12-L mRNA expression is an independent prognostic factor in resected p-stage I lung adenocarcinoma, and is significantly correlated with tumor differentiation stage and postoperative cancer recurrence.
