Variability, on the other hand, is measured by the frequency distribution of observed data. Biological variability adds to the uncertainty. The Constrained Disorder Principle (CDP) defines all systems in the universe by their inherent variability. According to the CDP, systems exhibit a degree of variability necessary for their proper function, allowing them to adapt to changes in their environments. Per the CDP, while variability differs from uncertainty, it can be viewed as a regulated mechanism for efficient functionality rather than uncertainty. This paper explores the various aspects of un-certainties in biology. It focuses on using CDP-based platforms for refining fuzzy algorithms to address some of the challenges associated with biological and medical uncertainties. Developing a fuzzy decision tree that considers the natural variability of systems can help minimize uncertainty. This method can reveal previously unidentified classes, reduce the number of unknowns, improve the accuracy of modeling results, and generate algorithm outputs that are more biologically and clinically relevant.</p>","PeriodicalId":48624,"journal":{"name":"Biology-Basel","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11505099/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Drug resistance remains a major challenge in CRC treatment, significantly affecting patient survival rates. Obesity is a key risk factor for CRC development, and accumulating evidence indicates that increased secretion of adipokines, including Visfatin, under obese conditions contributes to the development of resistance in CRC to various therapeutic methods. Amphiregulin (AREG) is a member of the epidermal growth factor (EGF) family, which activates the EGF receptor (EGFR), influencing multiple tumorigenic characteristics of cancers. Abnormal expression levels of AREG in cancer cells have been associated with resistance to anti-EGFR therapy in patients. However, it remains unclear whether this abnormal expression also impacts CRC resistance to other chemotherapeutic drugs. The aim of this study is to examine whether AREG expression levels could be affected in CRC cells under Visfatin stimulation, thereby initiating the development of resistance to 5-fluororacil (5-FU). Through our results, we found that Visfatin indeed increases AREG expression, reducing the sensitivity of HCT-116 CRC cells to 5-FU cytotoxicity. Moreover, AREG upregulation is regulated by STAT3-CREB transcription factors activated by JNK1/2 and p38 signaling. This study highlights the significant role of AREG upregulation in CRC cells in initiating chemotherapeutic resistance to 5-FU under Visfatin stimulation. These findings provide a deeper understanding of drug resistance development in CRC under obese conditions and offer new insights into the correlation between an abnormal increase in AREG levels and the development of 5-FU-resistance in CRC cells, which should be considered in future clinical applications.</p>","PeriodicalId":48624,"journal":{"name":"Biology-Basel","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11505234/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although AngII induced hypertension in both peri-AOF and male mice, peri-AOF females showed higher cytoplasmic GluN1 levels. In peri-AOF females, activation of ERß blocked hypertension and increased plasmalemmal GluN1 in axon terminals. In contrast, stimulation of ERß did not inhibit hypertension or influence presynaptic GluN1 localization in males.

There exists a fascinating relationship between parental genetic distance and genome dosage (polyploidy), and heterosis effects. The contribution of nuclear heterozygosity to heterosis is not uniform across diploid and polyploid crops, even within same species, thus demonstrating that polyploid crops should be part of any discussion on the mechanisms of heterosis. This review examines the records of correlating heterosis with parental genetic distance and the influence of adding supplementary genomes in wide crosses. Increasing nuclear heterozygosity through parental genetic distance has been shown to be an imperfect predictor for heterosis in a variety of commercial crops such as maize, rice, and pepper. However, increasing the ploidy level raises the maximum number of alleles that can be harboured at any one locus, and studies on crops such as oilseed rape, potato, alfalfa, maize, and rice have demonstrated that heterosis may be maximised upon increasing multi-locus nuclear heterozygosity. The novel heterotic phenotypes observed above the diploid level will contribute to our understanding on the mechanisms of heterosis and aid plant breeders in achieving the righteous goal of producing more food with fewer inputs.</p>","PeriodicalId":48624,"journal":{"name":"Biology-Basel","volume":"13 10","pages":""},"PeriodicalIF":3.6,"publicationDate":"2024-10-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11504056/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142510959","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
