Accurately classifying patients with non-small cell lung cancer (NSCLC) from the perspective of tumor evolution has not been systematically studied to date. Here, we reconstructed phylogenetic relationships of somatic mutations in 100 early NSCLC patients (327 lesions) through reanalyzing the TRACERx data. Based on the genomic evolutionary patterns presented on the phylogenetic trees, we grouped NSCLC patients into three evolutionary subtypes. The phylogenetic trees among three subtypes exhibited distinct branching structures, with one subtype representing branched evolution and another reflecting the early accumulation of genomic variation. However, in the evolutionary pattern of the third subtype, some mutations experienced selective sweeps and were gradually replaced by multiple newly formed subclonal populations. The subtype patients with poor prognosis had higher intra-tumor heterogeneity and subclonal diversity. We combined genomic heterogeneity with clinical phenotypes analysis and found that subclonal expansion results in the progression and deterioration of the tumor. The molecular mechanisms of subtype-specific Early Driver Feature (EDF) genes differed across the evolutionary subtypes, reflecting the characteristics of the subtype itself. In summary, our study provided new insights on the stratification of NSCLC patients based on genomic evolution that can be valuable for us to understand the development of pulmonary tumor profoundly.At the 2017 St. Gallen International Expert Consensus Conference on the Primary Therapy for Early Breast Cancer, the consensus panel recognized "partial breast irradiation as an option for women meeting the low-risk criteria put forward by the American Society for Radiation Oncology/European Society for Radiotherapy and Oncology (ASTRO/ESTRO) guideline," although acknowledging that there was less evidence for this approach. Partial breast irradiation is defined as irradiation localized to the surgical resection cavity only as opposed to the entire breast. Accelerated partial breast irradiation (APBI) involves intensive treatment in a short time period. The methods vary, and three available APBI options are brachytherapy, external beam and intra-operative irradiation. The long-term follow-up results from two large-scale, well-designed phase III randomized clinical trials have been released. However, further discussion of the optimal treatment candidates and delivery method is needed before the clinical application of APBI as a mainstream breast conservation treatment.We characterized a new cycloartane glycoside, herein known as aspleniumside F (1), along with five known compounds as kaempferol-3-O-[(6-O-(E)-feruloyl)-β-D-glucopyranosyl]-(1→2)-β-D-galacopyranoside (2), quercetin-3-O-[(6-O-(E)-feruloyl)-β-D-glucopyranosyl]-(1→2)-β-D-glucopyranoside (3), kaempferol-3-O-[(6-O-(E)-caffeoyl)-β-D-glucopyranosyl]-(1→2)-β-D-glucopyranoside (4), kaempferol-3-O-[(6-O-(E)-caffeoyl)-β-D-glucopyranosyl]-(1→2)-β-D-glucopyranosyl-7-O-β-D-glucopyranoside (5), and kaempferol-3-O-[(6-O-p-coumaroyl)-β-D-glucopyranosyl]-(1→2)-β-D-glucopyranosyl-7-O-β-D-glucopyranoside (6), from Asplenium ruprechtii Sa. PDGFR inhibitor Kurata, a folk medicine widely used to treat Thromboangiitis obliterans in China, Japan, and Korea. Based on spectroscopic, mainly 1D-, 2D-NMR and (+)-HR-ESI-MS, analyses as well as through comparisons with previous reports, its chemical structure was determined as 3β,24,30-tri-β-D-glucopyranosyl-23,25-dihydroxycycloartane (= (23R,24R)-3β,24-bis-(β-D-glucopyranosyloxy)-23,25-dihydroxy-9β-9,19-cyclolanostan-29-yl β-D-glucopyranoside). According to the 1 H coupling constant of anomeric protons and co-TLC of the acid hydrolysate with D-glucose, all three glycoside groups in 1 were revealed as β-D-glucopyranosyl. Furthermore, SOD-like antioxidant activity evaluation via IC50 of 12.43, 6.78, 9.12, 6.94 and 4.85 μM revealed that compounds 2-6 had bioactivity.Generation of high-affinity monoclonal antibodies by immunization of chickens is a valuable strategy, particularly for obtaining antibodies directed against epitopes that are conserved in mammals. A generic procedure is established for the humanization of chicken-derived antibodies. To this end, high-affinity binders of the epidermal growth factor receptor extracellular domain are isolated from immunized chickens using yeast surface display. Complementarity determining regions (CDRs) of two high-affinity binders are grafted onto a human acceptor framework. Simultaneously, Vernier zone residues, responsible for spatial CDR arrangement, are partially randomized. A yeast surface display library comprising ≈300 000 variants is screened for high-affinity binders in the scFv and Fab formats. Next-generation sequencing discloses humanized antibody variants with restored affinity and improved protein characteristics compared to the parental chicken antibodies. Furthermore, the sequencing data give new insights into the importance of antibody format, used during the humanization process. Starting from the antibody repertoire of immunized chickens, this work features an effective and fast high-throughput approach for the generation of multiple humanized antibodies with potential therapeutic relevance.Epidemiological and molecular studies have indicated that environmental exposure to organophosphate pesticides (OPPs) is associated with increased cancer risk; however, the underlying molecular mechanisms still need to be explained. Increasing cancer incidence is linked to OPPs-induced oxidative stress (OS). Our study evaluates monocrotophos (MCP) and chlorpyrifos (CP)-induced OS responses and apurinic/apyrimidinic endonuclease 1 (APE1) role in human non-small-cell lung cancer (NSCLC) cells. Our prior study has implicated OPPs-induced base excision repair (BER)-pathway dysregulation and APE1-mediated regulation of transcription factor (TF) c-jun in A549 cells. We further investigated the effects of MCP and CP on apoptosis, proliferation, and APE1's redox-regulation of nuclear factor-like 2 (Nrf2). Data demonstrates that MCP and CP at subtoxic concentrations induced reactive oxygen species generation and oxidative DNA base damage 8-oxo-dG lesions in NCI-H1299 cells. CP moderately upregulated the apoptosis-inducing factor (AIF) in A549 cells, however, it did not trigger other pro-apoptotic factors viz.
