RESUMO

T cells play an important role in adaptive immunity. Mature T cells specifically recognize antigens on major histocompatibility complex molecules through T-cell receptors (TCRs). As the TCR repertoire is highly diverse, its analysis is vital in the assessment of T cells. Advances in sequencing technology have provided convenient methods for further investigation of the TCR repertoire. In the present review, the TCR structure and the mechanisms by which TCRs function in tumor recognition are described. In addition, the potential value of the TCR repertoire in tumor diagnosis is reviewed. Furthermore, the role of the TCR repertoire in tumor immunotherapy is introduced, and the relationships between the TCR repertoire and the effects of different tumor immunotherapies are discussed. Based on the reviewed literature, it may be concluded that the TCR repertoire has the potential to serve as a biomarker for tumor prognosis. However, a wider range of cancer types and more diverse subjects require evaluation in future research to establish the TCR repertoire as a biomarker of tumor immunity.

RESUMO

Background: Because family caregivers of patients with a high-grade glioma experience high levels of distress and feel unprepared to perform the complex caregiving tasks associated with the disease and its treatment, we pilot-tested a caregiving skills intervention that integrates hands-on caregiving with coping skill training. Methods: In this single-arm trial, caregivers participated in a 4-session research nurse-led intervention involving simulation-based caregiving skills training at the hospital and psychoeducation delivered via videoconference. We collected measures of patients' and caregivers' psychological symptoms; caregivers' caregiving self-efficacy and role adjustment; and patients' cancer-related symptoms (MDASI) at baseline and again postintervention. We tracked feasibility data. Results: We approached 29 dyads of which 10 dyads (34%) consented. All patients (mean age: 60 years, 89% male) and caregivers (mean age: 58 years, 80% female, 80% spouses) completed the baseline and 7 dyads completed the follow-up assessments (attrition was related to patient's hospice transfer). Seven caregivers completed all 4 sessions and rated the program as beneficial. Paired t-tests revealed a significant improvement in caregiving self-efficacy at 6 weeks postintervention (t = -3.06, P = .02). Although improvements in caregiver role adjustment and patient and caregiver symptoms were not observed, no decreases in symptom burden or role adjustment were found during the follow-up period. Conclusions: This novel supportive care program appears to be safe, feasible, acceptable, and perceived as useful for caregivers of patients with high-grade glioma. Based on feasibility indicators and a signal of intervention efficacy, a randomized controlled trial is warranted.

RESUMO

OBJECTIVES: The primary objective of this retrospective review is to describe patient-reported improvement in muscular pain after initial treatment with onabotulinum toxin. A secondary objective was to determine other physiatry (physical medicine & rehabilitation (PM&R)) interventions ordered. METHODS: Preliminary retrospective review of physiatry interventions for 47 patients referred by breast radiation oncology to PM&R at a tertiary referral-based academic cancer centre clinic from 1 January 2018 to 31 December 2021 for muscular shoulder/chest wall pain. RESULTS: Patients were most commonly diagnosed with muscle spasm 27/47 (58%), lymphedema 21/47 (45%), myalgia/myofascial pain 16/47 (34%), radiation fibrosis 14/47 (30%), fatigue/deconditioning 13/47 (28%), neurological impairment 11/47 (23%) and joint pathology 3/47 (6%). The top three physiatric interventions were home exercise programme education (17/47, 36%), botulinum toxin injection (17/47, 36%) and physical or occupational therapy referral (15/47, 32%). Patients who had muscle spasms documented were more likely to have botulinum toxin recommended by physiatry (24/24) compared with those with questionable spasms (4/7) and those without spasms(0/16) (p=0.0005). 17/28 (60.7%) received botulinum toxin injection, and a total of 35 injections were performed during the study period. 94% (16/17) of patients who received botulinum toxin injection voiced improvement in pain after injection. CONCLUSION: Botulinum toxin injections may play a role in the treatment of muscle spasm-related pain in breast cancer survivors. Additional blinded controlled research on the effectiveness of botulinum toxin injection after breast cancer treatment with spastic muscular shoulder/chest wall pain is needed.

RESUMO

Background: Rehabilitation therapy is important to treat physical and functional impairments that may occur in individuals receiving physically taxing, yet potentially curative hematopoietic stem cell transplants (HSCT). However, there is scarce data on how rehabilitation is delivered during HSCT in real-life setting. Our objective is to assess the rehabilitation practices for adult patients hospitalized for HSCT in the United States. Methods: A 48-question online survey with cancer centers with the top 10% HSCT volumes (per American registries). We obtained data on patient characteristics, rehabilitation therapy details (timing, indication, administering providers), physical function objective and subjective outcome measures, and therapy activity precautions. Results: Fourteen (out of 21) institutions were included. Rehabilitation therapy referrals occurred at admission for all patients at 35.7% of the centers for: functional decline (92.9%), fall risk (71.4%), and discharge planning (71.4%). Participating institutions had physical therapists (92.9%), occupational therapists (85.7%), speech language pathologists (64.3%) and therapy aides (35.7%) in their rehabilitation team. Approximately 71% of centers used objective functional measures including sit-to-stand tests (50.0%), balance measures (42.9%), and six-minute walk/gait speed (both 35.7%). Monitoring of blood counts to determine therapy modalities frequently occurred and therapies held for low platelet or hemoglobin values; but absolute neutrophil values were not a barrier to participate in resistance or aerobic therapies (42.9%). Discussion: Rehabilitation practices during HSCT varied among the largest volume cancer centers in the United States, but most centers provided skilled therapy, utilized objective, clinician and patient reported outcomes, and monitored blood counts for safety of therapy administration.

RESUMO

BACKGROUND: Colorectal cancer (CRC) is a serious global health burden because of its high morbidity and mortality rates. Hypoxia and massive lactate production are hallmarks of the CRC microenvironment. However, the effects of hypoxia and lactate metabolism on CRC have not been fully elucidated. This study aimed to develop a novel molecular subtyping based on hypoxia-related genes (HRGs) and lactate metabolism-related genes (LMRGs) and construct a signature to predict the prognosis of patients with CRC and treatment efficacy. METHODS: Bulk and single-cell RNA-sequencing and clinical data of CRC were downloaded from the TCGA and GEO databases. HRGs and LMRGs were obtained from the Molecular Signatures Database. The R software package DESeq2 was used to perform differential expression analysis. Molecular subtyping was performed using unsupervised clustering. A predictive signature was developed using univariate Cox regression, random forest model, LASSO, and multivariate Cox regression analyses. Finally, the sensitivity of tumor cells to chemotherapeutic agents before and after hypoxia was verified using in vitro experiments. RESULTS: We classified 575 patients with CRC into three molecular subtypes and were able to distinguish their prognoses clearly. The C1 subtype, which exhibits high levels of hypoxia, has a low proportion of CD8 + T cells and a high proportion of macrophages. The expression of immune checkpoint genes is generally elevated in C1 patients with severe immune dysfunction. Subsequently, we constructed a predictive model, the HLM score, which effectively predicts the prognosis of patients with CRC and the efficacy of immunotherapy. The HLM score was validated in GSE39582, GSE106584, GSE17536, and IMvigor210 datasets. Patients with high HLM scores exhibit high infiltration of CD8 + exhausted T cells (Tex), especially terminal Tex, and oxidative phosphorylation (OXPHOS)-Tex in the immune microenvironment. Finally, in vitro experiments confirmed that CRC cell lines were less sensitive to 5-fluorouracil, oxaliplatin, and irinotecan under hypoxic conditions. CONCLUSION: We constructed novel hypoxia- and lactate metabolism-related molecular subtypes and revealed their immunological and genetic characteristics. We also developed an HLM scoring system that could be used to predict the prognosis and efficacy of immunotherapy in patients with CRC.

RESUMO

Background: Is de novo metastatic breast cancer (dnMBC) the same disease in the elderly as in younger breast cancer remains unclear. This study aimed to determine the metastatic patterns and survival outcomes in dnMBC according to age groups. Methods: We included patients from the Surveillance Epidemiology and End Results program. Chi-square test, multivariate logistic regression analyses, and multivariate Cox regression models were used for statistical analyses. Results: A total of 17719 patients were included. There were 3.6% (n=638), 18.6% (n=3290), 38.0% (n=6725), and 39.9% (n=7066) of patients aged <35, 35-49, 50-64, and ≥65 years, respectively. Older patients had a significantly higher risk of lung metastasis and a significantly lower risk of liver metastasis. There were 19.1%, 25.6%, 30.9%, and 35.7% of patients with lung metastasis in those aged <35, 35-49, 50-64, and ≥65 years, respectively. Moreover, the proportion of liver metastasis was 37.6%, 29.5%, 26.3%, and 19.2%, respectively. Age was the independent prognostic factor associated with breast cancer-specific survival (BCSS) and overall survival (OS). Those aged 50-64 years had significantly inferior BCSS (P<0.001) and OS (P<0.001) than those aged <35 years. Patients aged ≥65 years also had significantly lower BCSS (P<0.001) and OS (P<0.001) than those aged <35 years. However, similar outcomes were found between those aged 35-49 and <35 years. Conclusion: Our study suggests that different age groups may affect the metastatic patterns among patients with dnMBC and the survival of younger patients is more favorable than those of older patients.

RESUMO

Interleukin-27 (IL-27) is a member of the IL-12 family. The gene encoding IL-27 is located at chromosome 16p11. IL-27 is considered as a heterodimeric cytokine, which consists of Epstein-Barr virus (EBV)-induced gene 3 (Ebi3) and IL-27p28. Based on the function of IL-27, it binds to receptor IL-27rα or gp130 and then regulates downstream cascade. To date, findings show that the expression of IL-27 is abnormal in different inflammatory autoimmune diseases (including systemic lupus erythematosus, rheumatoid arthritis, Sjogren syndrome, Behcet's disease, inflammatory bowel disease, multiple sclerosis, systemic sclerosis, type 1 diabetes, Vogt-Koyanagi-Harada, and ankylosing spondylitis). Moreover, in vivo and in vitro studies demonstrated that IL-27 is significantly in3volved in the development of these diseases by regulating innate and adaptive immune responses, playing either an anti-inflammatory or a pro-inflammatory role. In this review, we comprehensively summarized information about IL-27 and autoimmunity based on available evidence. It is hoped that targeting IL-27 will hold great promise in the treatment of inflammatory autoimmune disorders in the future.

RESUMO

Trisarcglaboids A and B (1 and 2), representing the first example of lindenane sesquiterpenoid trimers repolymerized based on the classical [4 + 2] type dimer, together with known biogenic precursors chlorahololide D (3) and sarcandrolide A (4), were identified as chemical components of the root of Sarcandra glabra. The novel trimeric lindenane sesquiterpenoid skeletons, including their absolute configurations, were characterized using MS, NMR, ECD, and X-ray single crystal diffraction. The proposed Diels-Alder cycloaddition between Δ2(3) of the tiglic acyl group of the classical [4 + 2] type dimer and Δ15(4),5(6) of the third lindenane may serve as the key biogenic step. In addition, compound 1 exerted significant cytotoxicity against five human cancer cell lines with IC50 values ranging from 1 to 7 µM, potentially through blocking Akt phosphorylation and activating the endogenous apoptosis pathway.

RESUMO

OBJECTIVES: Concurrent chemoradiation to treat head and neck cancer (HNC) may result in debilitating toxicities. Targeted exercise such as yoga therapy may buffer against treatment-related sequelae; thus, this pilot RCT examined the feasibility and preliminary efficacy of a yoga intervention. Because family caregivers report low caregiving efficacy and elevated levels of distress, we included them in this trial as active study participants. METHODS: HNC patients and their caregivers were randomized to a 15-session dyadic yoga program or a waitlist control (WLC) group. Prior to randomization, patients completed standard symptom (MDASI-HN) and patients and caregivers completed quality of life (SF-36) assessments. The 15-session program was delivered parallel to patients' treatment schedules. Participants were re-assessed at patients' last day of chemoradiation and again 30 days later. Patients' emergency department visits, unplanned hospital admissions and gastric feeding tube placements were recorded over the treatment course and up to 30 days later. RESULTS: With a consent rate of 76%, 37 dyads were randomized. Participants in the yoga group completed a mean of 12.5 sessions and rated the program as "beneficial." Patients in the yoga group had clinically significantly less symptom interference and HNC symptom severity and better QOL than those in the WLC group. They were also less likely to have a hospital admission (OR = 3.00), emergency department visit (OR = 2.14), and/or a feeding tube placement (OR = 1.78). CONCLUSION: Yoga therapy appears to be a feasible, acceptable, and possibly efficacious behavioral supportive care strategy for HNC patients undergoing chemoradiation. A larger efficacy trial is warranted.

RESUMO

OBJECTIVE: The aim of the study is to identify and appraise current evidence for rehabilitation interventions in head and neck cancer. DESIGN: A previously published scoping review spanning 1990 through April 2017 was updated through January 11, 2023 and narrowed to include only interventional studies (Arch Phys Med Rehabil. 2019;100(12):2381-2388). Included studies had a majority head and neck cancer population and rehabilitation-specific interventions. Pairs of authors extracted data and evaluated study quality using the PEDro tool. Results were organized by intervention type. RESULTS: Of 1338 unique citations, 83 studies with 87 citations met inclusion criteria. The median study sample size was 49 (range = 9-399). The most common interventions focused on swallow (16 studies), jaw (11), or both (6), followed by whole-body exercise (14) and voice (10). Most interventions took place in the outpatient setting (77) and were restorative in intent (65 articles). The overall study quality was fair (median PEDro score 5, range 0-8); none were of excellent quality (PEDro >9). CONCLUSIONS: Most head and neck cancer rehabilitation interventions have focused on restorative swallow and jaw exercises and whole-body exercise to address dysphagia, trismus, and deconditioning. More high-quality evidence for head and neck cancer rehabilitation interventions that address a wider range of impairments and activity and social participation limitations during various cancer care phases is urgently needed to reduce head and neck cancer-associated morbidity.

RESUMO

Background: Mucinous adenocarcinoma (MAC) is a unique subtype of colorectal cancer and its prognostic value remains controversial. This study aimed to compare the clinicopathological characteristics and prognostic differences between patients with MAC and non-mucinous adenocarcinoma (NMAC). Methods: 674 patients with NMAC, 110 patients with adenocarcinoma with mucinous component (ACWM) and 77 patients with MAC between 2016-2019 were enrolled in the study. Univariate and multivariate Cox regression were performed to analyze the factors associated with prognosis. Predictive nomograms of overall survival (OS) and cancer-specific survival (CSS) for patients with colorectal adenocarcinoma were constructed. Confounding factors were eliminated by propensity score matching (PSM). Results: Compared with patients with NMAC, patients with MAC were more likely to have a tumor located at the proximal colon, present with a larger tumor diameter, more advanced T stage, higher frequency of metastasis, deficiency of mismatch repair, and elevated preoperative carcinoembryonic antigen. Patients with MAC were related to worse OS (HR=2.53, 95%CI 1.73-3.68, p<0.01) and CSS (HR=3.09, 95%CI 2.10-4.57, p<0.01), which persisted after PSM. Subgroup analysis demonstrated that patients with left-sided or stage III/IV MAC exhibited a comparatively worse OS and CSS than those with NMAC. Furthermore, in patients with stage II with a high-risk factor and stage III MAC, adjuvant chemotherapy was associated with an improved OS, CSS, and RFS. Conclusion: Compared with the NMAC phenotype, the MAC phenotype was an independent risk factor for poor prognosis in colorectal adenocarcinoma with worse OS and CSS, particularly patients with left-sided colorectal cancer and stage III/IV. However, patients with MAC can still benefit from adjuvant chemotherapy.

RESUMO

INTRODUCTION: Physical rehabilitation is increasingly incorporated throughout the allogeneic hematopoietic stem cell transplant (allo-HSCT) journey for older adults. OBJECTIVE: This study aimed to describe physical medicine and rehabilitation (PM&R)-related diagnoses, exercise barriers, and management recommendations for older adults before allo-HSCT. DESIGN: Fifty PM&R consults as part of the Enhanced Recovery-Stem Cell Transplant (ER-SCT) multidisciplinary prehabilitation program at a comprehensive cancer center were retrospectively reviewed. RESULTS: Many PM&R-related diagnoses (173), exercise barriers (55), and management recommendations (112) were found. Common diagnoses were musculoskeletal dysfunction (more commonly back, shoulder, then knee) (n = 39, 23%) and fatigue (n = 36, 21%). Common exercise barriers were also musculoskeletal dysfunction (more commonly back, knee, then shoulder) (total n = 20, 36%) and fatigue (n = 20, 36%). Most patients (n = 32, 64%) had 1 or more exercise barriers. Common PM&R management recommendations were personalized exercise counseling (n = 37, 33%), personalized nutrition management (n = 19, 17%), body composition recommendations (n = 17, 15%), medications (n = 15, 13%), and orthotics and durable medical equipment (n = 8, 7%). CONCLUSION: Routine PM&R referral of older allo-HSCT patients for prehabilitation resulted in the identification of many rehabilitative needs and substantial additional management recommendations. Increased early, collaborative prehabilitation efforts between PM&R and allo-HSCT teams to optimize care for these patients is recommended.

RESUMO

Endophilin is an evolutionarily conserved family of protein that involves in a range of intracellular membrane dynamics. This family consists of five isoforms, which are distributed in various tissues. Recent studies have shown that Endophilin regulates diseases pathogenesis, including neurodegenerative diseases, tumors, cardiovascular diseases, and autoimmune diseases. In vivo, it regulates different biological functions such as vesicle endocytosis, mitochondrial morphological changes, apoptosis and autophagosome formation. Functional studies confirmed the role of Endophilin in development and progression of these diseases. In this study, we have comprehensively discussed the complex function of Endophilin and how the family contributes to diseases development. It is hoped that this study will provide new ideas for targeting Endophilin in diseases.

RESUMO

BACKGROUND/OBJECTIVE: The Tomita, revised Tokuhashi and Tokuhashi lung scores are commonly used tools to predict the survival of patients with spinal metastases and to guide decisions regarding surgical treatment. These prognostic scores, however, tend to underestimate the prognosis of patients with lung cancer. We examined surgical outcome and hopefully provide a more accurate reference for management. METHODS: The consistency between predicted and actual survival was examined using the Tomita and Tokuhashi scores. Various factors that may influence survival were analyzed. Primary outcomes were overall survival (OS) and progression-free survival (PFS), defined as the ambulatory time after the initial surgery. Secondary outcomes included reoperation events, blood loss, and hospitalization days. RESULTS: One hundred seventy-two patients were enrolled. Correct survival predictions were made for 28%, 42%, and 56% with the Tomita, revised Tokuhashi, and Tokuhashi lung scores, respectively. The Tokuhashi lung scores underestimated OS by 35%-40%. Body mass index ≥20, systemic treatment-naïve, good general condition, the use of denosumab, and adenocarcinoma were found to positively affect OS and PFS. There was no significant difference between palliative decompression and excisional surgery regarding OS and PFS. CONCLUSION: Patients with spinal metastases from lung cancer had better prognosis than that predicted by the Tomita and Tokuhashi scores. Spine surgeons should acknowledge this discrepancy and treat these patients with at least the aggressiveness suggested. Patients with adenocarcinoma, amenable to target therapy, denosumab, good general condition, systemic treatment-naïve are better candidates for surgery. Those with cachexic status and unresectable visceral metastases are worse candidates.

RESUMO

OBJECTIVE: The long-term survival data of lung cancer patients with spinal metastases are crucial for informed treatment decision-making. However, most studies in this field involve small sample sizes. Moreover, survival benchmarking and an analysis of changes in survival over time are required, but data are unavailable. To meet this need, we performed a metaanalysis of survival data from small studies to obtain a survival function based on largescale data. METHODS: We performed a single-arm systematic review of survival function following a published protocol. Data of patients who received surgical, nonsurgical, and mixed modes of treatment were meta-analyzed separately. Survival data were extracted from published figures with a digitizer program and then processed in R. Median survival time was used as an effect size for moderator analysis to explain the heterogeneity. RESULTS: Sixty-two studies with 5,242 participants were included for pooling. The survival functions showed a median survival of 6.72 months for surgery (95% confidence interval [CI], 61.9-7.01; 2,367 participants; 36 studies), 5.99 months for nonsurgery (95% CI, 5.33-6.47; 891 participants; 12 studies), and 5.96 months for mixed (95% CI, 5.67-6.43; 1,984 participants; 18 studies). Patients enrolled since 2010 showed the highest survival rates. CONCLUSION: This study provides the first large-scale data for lung cancer with spinal metastasis that allows survival benchmarking. Data from patients enrolled since 2010 had the best survival and thus may more accurately reflect current survival. Researchers should focus on this subset in future benchmarking and remain optimistic in the management of these patients.

RESUMO

OBJECTIVE: Diagnosis of lupus nephritis (LN) is a complex process, which usually requires renal biopsy. We aim to establish a machine learning pipeline to help diagnosis of LN. METHODS: A cohort of 681 systemic lupus erythematosus (SLE) patients without LN and 786 SLE patients with LN was established, and a total of 95 clinical, laboratory data and 17 meteorological indicators were collected. After tenfold cross-validation, the patients were divided into training set and test set. The features selected by collective feature selection method of mutual information (MI) and multisurf were used to construct the models of logistic regression, decision tree, random forest, naive Bayes, support vector machine (SVM), light gradient boosting (LGB), extreme gradient boosting (XGB), and artificial neural network (ANN), the models were compared and verified in post-analysis. RESULTS: Collective feature selection method screens out antistreptolysin (ASO), retinol binding protein (RBP), lupus anticoagulant 1 (LA1), LA2, proteinuria and other features, and the hyperparameter optimized XGB (ROC: AUC = 0.995; PRC: AUC = 1.000, APS = 1.000; balance accuracy: 0.990) has the best performance, followed by LGB (ROC: AUC = 0.992; PRC: AUC = 0.997, APS = 0.977; balance accuracy: 0.957). The worst performance is naive Bayes model (ROC: AUC = 0.799; PRC: AUC = 0.822, APS = 0.823; balance accuracy: 0.693). In the composite feature importance bar plots, ASO, RF, Up/Ucr, and other features play important roles in LN. CONCLUSION: We developed and validated a new and simple machine learning pathway for diagnosis of LN, especially the XGB model based on ASO, LA1, LA2, proteinuria, and other features screened out by collective feature selection.

RESUMO

PURPOSE: Patients with ovarian metastasis of colorectal cancer (CROM) usually have poor prognosis. Metastasectomy is controversial in patients with CROM. This study aims to evaluate the prognostic value of ovarian metastasectomy and other factors in CROM patients. METHODS: We searched literature up to November 1, 2021 in MEDLINE (PubMed), Embase, Cochrane Library, and Clinicaltrials.gov. Retrospective studies were assessed if survival outcome of CROM patients was reported. Results were pooled in a random-effects model and reported as hazard ratios (HRs) with 95% confidence intervals (CI). Sensitivity was analyzed. RESULTS: Among 2497 studies screened, 15 studies with 997 patients, published between 2000 and 2021, were included. Longer overall survival (OS) was correlated with ovarian metastasectomy (pooled HR = 0.44, 95% CI: 0.34-0.58, P < 0.05) and R0 resection (pooled HR = 0.26, 95% CI: 0.16-0.41, P < 0.05). Longer disease-specific survival (DSS) was associated with systematic chemotherapy (pooled HR = 0.26, 95% CI: 0.15-0.45, P < 0.0001). Shorter OS was associated with extraovarian metastases (pooled HR = 3.00, 95% CI 1.68-5.36, P < 0.05) and bilateral OM (pooled HR = 1.66, 95% CI: 1.09-2.51, P < 0.05). No significant difference in OS was observed among patients with systematic chemotherapy (pooled HR = 0.68, 95% CI: 0.35-1.31, P > 0.05). CONCLUSION: Metastasectomy achieving R0 resection can significantly prolong OS and DSS of CROM patients as a reasonable treatment modality.

RESUMO

Metastasis is commonly occurred in gastric cancer, and it is caused and responsible for one of the major cancer-related mortality in gastric cancer patients. Allyl isothiocyanate (AITC), a natural product, exhibits anticancer activities in human many cancer cells, including gastric cancer. However, no available report shows AITC inhibits gastric cancer cell metastasis. Herein, we evaluated the impact of AITC on cell migration and invasion of human gastric cancer AGS cells in vitro. AITC at 5-20 µM did not induce significant cell morphological damages observed by contrast-phase microscopy but decreased cell viability assayed by flow cytometry. After AGS cells were further examined by atomic force microscopy (AFM), which indicated AITC affected cell membrane and morphology in AGS cells. AITC significantly suppressed cell motility examined by scratch wound healing assay. The results of the gelatin zymography assay revealed that AITC significantly suppressed the MMP-2 and MMP-9 activities. In addition, AITC suppressed cell migration and invasion were performed by transwell chamber assays at 24 h in AGS cells. Furthermore, AITC inhibited cell migration and invasion by affecting PI3K/AKT and MAPK signaling pathways in AGS cells. The decreased expressions of p-AKTThr308 , GRB2, and Vimentin in AGS cells also were confirmed by confocal laser microscopy. Our findings suggest that AITC may be an anti-metastasis candidate for human gastric cancer treatment.

RESUMO

Background: Mucinous adenocarcinoma (MAC) is a unique clinicopathological colorectal cancer (CRC) type that has been recognized as a separate entity from non-mucinous adenocarcinoma (NMAC), with distinct clinical, pathologic, and molecular characteristics. We aimed to construct prognostic signatures and identifying candidate biomarkers for patients with MAC. Methods: Differential expression analysis, weighted correlation network analysis (WGCNA), and least absolute shrinkage and selection operator (LASSO)-Cox regression model were used to identify hub genes and construct a prognostic signature based on RNA sequencing data from TCGA datasets. The Kaplan-Meier survival curve, gene set enrichment analysis (GSEA), cell stemness, and immune infiltration were analyzed. Biomarker expression in MAC and corresponding normal tissues from patients operated in 2020 was validated using immunohistochemistry. Results: We constructed a prognostic signature based on ten hub genes. Patients in the high-risk group had significantly worse overall survival (OS) than patients in the low-risk group (p < 0.0001). We also found that ENTR1 was closely associated with OS (p = 0.016). ENTR1 expression was significantly positively correlated with cell stemness of MAC (p < 0.0001) and CD8+ T cell infiltration (p = 0.01), whereas it was negatively associated with stromal scores (p = 0.03). Finally, the higher expression of ENTR1 in MAC tissues than in normal tissues was validated. Conclusion: We established the first MAC prognostic signature, and determined that ENTR1 could serve as a prognostic marker for MAC.
