There has been a lack of significant attention given to studying first-generation college students in undergraduate engineering, and therefore, there is limited understanding of how to navigate post-secondary education as a first-generation college student to succeed in undergraduate engineering. Here, I lay out tips for success based on my own experience as a first-generation student in engineering. This includes how to find the right major for you, adjust to college, have a solid support system, seek out research opportunities, become involved in outreach, experience inclusivity, balance courses with other commitments, and apply for scholarships.

The BRI-binding site consists of three hotspot regions on BMP surface, which totally contribute ~70% potency to the BMP-BRI binding events and represent the core sections of BMP conformational wrist epitope; the contribution increases in the order: hotspot 2 (~ 8%) < hotspot 3 (~ 20%) < hotspot 1 (~ 40%). Multiple sequence alignment and structural superposition revealed a consensus sequence pattern and a similar binding mode of the three hotspots shared by most BMP members, indicating a high conservation of wrist epitope in BMP family. The three hotspots are natively folded into wellstructured <i>U</i>-shaped,, loop and double-stranded conformations in BMP proteins, which, however, would become largely disordered when splitting from the protein context to derive osteogenic peptides in free state, thus largely impairing their rebinding capability to BRI receptor. In this respect, cyclization strategy was employed to constrain hotspot 1/3-derived peptides into a native-like conformation, which was conducted by adding a disulfide bond across the ending arms of linear peptides based on their native conformations. Fluorescence-based assays substantiated that the cyclization can effectively improve the binding affinities of osteogenic peptides to BRI receptor by 3-6-fold. The cyclic peptides also exhibit a good selectivity for BRI over BRII (> 5-fold), confirming that they can specifically target the wrist epitope-binding site of BRI receptor.</p><p><strong>Conclusion: </strong>The rationally designed cyclic peptides can be regarded as the promising lead entities that should be further chemically modified to enhance their in vivo biological stability for further bioengineering therapeutic osteogenic peptides against chondrocyte senescence and bone disorder.</p>","PeriodicalId":9687,"journal":{"name":"Cellular and molecular bioengineering","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9474794/pdf/12195_2022_Article_725.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9416442","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

On the other hand, cancer cells are shown to influence the local hemodynamics in their vicinity, in microvasculature. The first objective of present study is to explore how cancer cell-induced changes in local hemodynamics can impact the forces experienced by intra/inter-cellular organelles of ECs that are believed to play important roles in mechanotransduction. Moreover, extracellular matrix (ECM) stiffening has been shown to correlate with progression of most cancer types. However, it is still not well understood how ECM stiffness impacts ECs mechanosensors. The second objective of this study is to elucidate the role of ECM stiffness on mechanotransduction in ECs. <i>Methods</i>-A three-dimensional, multiscale, multicomponent, viscoelastic model of focally adhered ECs is developed to simulate the force transmission through ECs mechanosensors [actin cortical layer, nucleus, cytoskeleton, focal adhesions (FAs), and adherens junctions (ADJs)]. <i>Results</i>-Our results show that cancer cell-altered hemodynamics results in significantly high forces transmitted to subcellular organelles of ECs which are in vicinity of cancer cells. This impact is more drastic on stress fibers (SFs) both centrally located and peripheral ones. Furthermore, we demonstrate that ADJs, FAs, and SFs experience higher stresses in ECs attached to stiffer ECM. Impact of ECM stiffness is particularly significant in ECs exposed to fluid shear stresses of 2 Pa or lower. This finding reveals the role of organ-specific stiffness in promoting cancer cell transmigration even in capillaries larger than cancer cell diameter. <i>Conclusions</i>-ÊCancer cell-induced-changes in ECs mechanotransduction represents an important potential mechanism for cancer cell transmigration in the microvasculature particularly with stiffer ECM. The identification of ECs mechanosensors involved in early stages of EC-cancer cell interaction will help with developing more efficient therapeutic interventions to suppress cancer cell transmigration in the microvasculature.</p>","PeriodicalId":9687,"journal":{"name":"Cellular and molecular bioengineering","volume":null,"pages":null},"PeriodicalIF":2.8,"publicationDate":"2022-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9474981/pdf/12195_2022_Article_728.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9808877","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
