Background: Nicotinamide (NAM+) regulates redox and metabolic activities in the mitochondria. The intention of the research was to identify key genes that relate to nicotinamide in hepatocellular carcinoma (HCC).
Methods: Relevant clinical information were collected as well as RNA-seq data using the Cancer Genome Atlas (TCGA) database. Differential analysis was used to discover the genes that were differently expressed. On the key genes associated with NAM, functional enrichment analysis was carried out. Next, receiver operating characteristic (ROC) and prognosis Kaplan-Meier (K-M) curve analyses were used to evaluate the importance of important gene expression, respectively. The immune cell signatures were estimated using the CIBERSORT algorithm. Finally, the anticancer impact of NAM on HCC was experimentally confirmed, and important genes NADSYN1 and NT5C were validated at the protein level in clinical specimens.
Results: Six prognostic key genes (NAXE, NADSYN1, NT5C, NT5C3A, PNP and NT5E) were identified. There is an association between the level of key gene expression and the clinical prognosis. Four key genes (NAXE, NADSYN1, NT5C and NT5C3A) have statistical significance of survival prognosis. Finally, the expression of NAM-related genes and the inhibitory effect of NAM on HCC were verified by experiments.
Conclusion: The study first found some Nicotinamide metabolism-related differentially expressed genes (NMRDEGs) that are related to HCC can contribute to predicting survival and monitoring the treatment.

Objective: MCM5 is a DNA licensing factor involved in cell proliferation and has been previously established as an excellent biomarker in a number of malignancies. Nevertheless, the role of MCM5 in GBM has not been fully clarified. The present study aimed to investigate the potential roles of MCM5 in the treatment of GBM and to elucidate its underlying mechanism, which is beneficial for developing new therapeutic strategies and predicting prognosis.
Methods: Firstly, we obtained transcriptomic and proteomic data from the TCGA and CPTAC databases on glioma patients. Employing the DeSeq2 R package, we then identified genes with joint differential expression in GBM tissues subjected to chemotherapy. To develop a prognostic risk score model, we performed univariate and multivariate Cox regression analyses. In vitro knockdown and overexpression of MCM5 were used to further investigate the biological functions of GBM cells. Additionally, we also delved into the upstream regulation of MCM5, revealing associations with several transcription factors. Finally, we investigated differences in immune cell infiltration and drug sensitivity across diverse risk groups identified in the prognostic risk model.
Results: In this study, the chemotherapy-treated GBM samples exhibited consistent alterations in 46 upregulated and 94 downregulated genes at both the mRNA and protein levels. Notably, MCM5 emerged as a gene with prognostic significance as well as potential therapeutic relevance. In vitro experiments subsequently validated the role of increased MCM5 expression in promoting GBM cell proliferation and resistance to TMZ. Correlations with transcription factors such as CREB1, CTCF, NFYB, NRF1, PBX1, TEAD1, and USF1 were discovered during upstream regulatory analysis, enriching our understanding of MCM5 regulatory mechanisms. The study additionally delves into immune cell infiltration and drug sensitivity, providing valuable insights for personalized treatment approaches.
Conclusion: This study identifies MCM5 as a key player in GBM, demonstrating its prognostic significance and potential therapeutic relevance by elucidating its role in promoting cell proliferation and resistance to chemotherapy.

Keywords: glioblastoma, minichromosome maintenance protein 5, chemotherapeutic drug resistance

Abstract: Primary cancer of the ileum is rare, and when it occurs in conjunction with primary colon cancer, it becomes even more infrequent and challenging to diagnose prior to surgical intervention. Primary small bowel cancers can be overlooked and may be misidentified as small bowel mesenchymal tumours or advanced metastases from colon cancer. We present an exceedingly uncommon case of ruptured primary ileal cancer combined with primary descending colon cancer presenting with gastrointestinal bleeding. Based on our understanding, instances of dual tumours concurrently occurring are exceedingly infrequent. In this patient, there was a preoperative suspicion of bleeding from colon cancer in the descending region. However, intraoperative exploration revealed that the location of the bleeding was a terminal ileal mass. Following the surgical intervention, the patient recovered satisfactorily. Intraoperative exploration of the entire gastrointestinal tract is therefore necessary in patients with gastrointestinal haemorrhage, especially in those who require urgent surgery without adequate preoperative investigations. If a mass is detected at the end of the ileum, intraoperative pathology should be performed if feasible. Subsequently, if the diagnosis reveals an adenocarcinoma, terminal ileocolic resection and right hemicolectomy are necessary for appropriate resection.

Keywords: multiple primary malignant neoplasms, gut bleeding, adenocarcinoma of the small bowel, descending colon cancer, gastrointestinal tumours, case report
摘要:回肠原发性癌症非常罕见,当它与原发性结肠癌同时发生时,就变得更加罕见,而且在手术干预前进行诊断也很困难。原发性小肠癌容易被忽视,可能被误认为是小肠间质瘤或结肠癌晚期转移瘤。我们介绍了一例极为罕见的原发性回肠癌破裂合并原发性降结肠癌并伴有消化道出血的病例。根据我们的了解,同时发生双重肿瘤的病例极为罕见。在这名患者中,术前怀疑是降结肠部位的结肠癌引起的出血。但术中探查发现,出血部位是回肠末端肿块。手术治疗后,患者恢复良好。因此,对于胃肠道出血患者,尤其是需要紧急手术但术前检查不充分的患者,术中有必要对整个胃肠道进行探查。如果在回肠末端发现肿块,应在可行的情况下进行术中病理检查。关键词:多发性原发性恶性肿瘤;肠道出血;小肠腺癌;降结肠癌;胃肠道肿瘤;病例报告

Background: Colorectal cancer (CRC) is one of the deadliest causes of death by cancer worldwide. Liver metastasis (LM) is the main cause of death in patients with CRC. Therefore, identification of patients with the greatest risk of liver metastasis is critical for early treatment and reduces the mortality of patients with colorectal cancer liver metastases.
Methods: Initially, we characterized cell composition through single-cell transcriptome analysis. Subsequently, we employed copy number variation (CNV) and pseudotime analysis to delineate the cellular origins of LM and identify LM-related epithelial cells (LMECs). The LM-index was constructed using machine learning algorithms to forecast the relative abundance of LMECs, reflecting the risk of LM. Furthermore, we analyzed drug sensitivity and drug targeted gene expression in LMECs and patients with a high risk of LM. Finally, functional experiments were conducted to determine the biological roles of metastasis-related gene in vitro.
Results: Single-cell RNA sequencing analysis revealed different immune landscapes between primary CRC and LM tumor. LM originated from chromosomal variants with copy number loss of chr1 and chr6p and copy number gain of chr7 and chr20q. We identified the LMECs cluster and found LM-associated pathways such as Wnt/beta-catenin signaling and KRAS signaling. Subsequently, we identified ten metastasis-associated genes, including SOX4, and established the LM-index, which correlates with poorer prognosis, higher stage, and advanced age. Furthermore, we screened two drugs as potential candidates for treating LM, including Linsitinib_1510, Lapatinib_1558. Immunohistochemistry results demonstrated significantly elevated SOX4 expression in tumor samples compared to normal samples. Finally, in vitro experiments verified that silencing SOX4 significantly inhibited tumor cell migration and invasion.
Conclusion: This study reveals the possible cellular origin and driving factors of LM in CRC at the single cell level, and provides a reference for early detection of CRC patients with a high risk of LM.

背景:结肠直肠癌(CRC)是全球最致命的癌症死因之一。肝转移(LM)是导致 CRC 患者死亡的主要原因。因此,识别肝转移风险最大的患者对于早期治疗和降低结直肠癌肝转移患者的死亡率至关重要:最初,我们通过单细胞转录组分析确定了细胞组成的特征。随后,我们利用拷贝数变异(CNV)和伪时间分析来确定肝转移瘤的细胞起源,并识别与肝转移瘤相关的上皮细胞(LMECs)。我们利用机器学习算法构建了 LM 指数,以预测 LMEC 的相对丰度,从而反映出 LM 的风险。此外,我们还分析了 LMEC 和 LM 高危患者的药物敏感性和药物靶向基因表达。最后,我们进行了功能实验,以确定转移相关基因在体外的生物学作用:结果:单细胞RNA测序分析表明,原发性CRC和LM肿瘤的免疫景观不同。LM起源于染色体变异,chr1和chr6p拷贝数丢失,chr7和chr20q拷贝数增大。我们确定了 LMECs 群,并发现了与 LM 相关的通路,如 Wnt/beta-catenin 信号转导和 KRAS 信号转导。随后,我们确定了包括 SOX4 在内的十个转移相关基因,并建立了 LM 指数,该指数与较差的预后、较高的分期和高龄相关。此外,我们还筛选出两种治疗 LM 的潜在候选药物,包括 Linsitinib_1510、Lapatinib_1558。免疫组化结果显示,与正常样本相比,肿瘤样本中SOX4的表达明显升高。最后,体外实验验证了沉默SOX4能显著抑制肿瘤细胞的迁移和侵袭:结论:这项研究从单细胞水平揭示了乳腺癌可能的细胞起源和驱动因素,为早期发现乳腺癌高危人群提供了参考。

Abstract: Gastric adenocarcinoma (GAS) is a rare subtype of mucinous adenocarcinoma characterized by gastric differentiation and is unrelated to human papillomavirus (HPV) infection. This report discusses a 40-year-old female who presented with abdominal distension accompanied by increased abdominal circumference. CT of the abdomen and pelvis showed a large 21.0&ast12.7&ast26.0 cm mass later diagnosed as GAS combined with squamous cell carcinoma on surgical pathology. Immunohistological staining of GAS was positive for CK7, MUC6, PAX-8 CEA, and P53 (wild type) and negative for CDX2, CK20, ER, PR, P16, and WT1. The proliferative index (Ki-67) was 20%. Immunohistochemical staining of squamous cell carcinoma was positive for P16 and P53 (wild type), and the proliferative index (Ki-67) was 90%. However, the pathogenesis and molecular mechanisms of GAS have not been fully elucidated. As more cases are identified and reported, additional targeted therapies can be developed and tested in these patients.

Keywords: cervical cancer, gastric type, adenocarcinoma
摘要:胃腺癌(GAS)是粘液腺癌的一种罕见亚型,以胃分化为特征,与人类乳头瘤病毒(HPV)感染无关。本报告讨论了一名 40 岁女性的病例,她出现腹胀并伴有腹围增大。腹部和盆腔 CT 显示,腹部有一个 21.0&ast12.7&ast26.0 厘米大的肿块,后经手术病理诊断为 GAS 合并鳞状细胞癌。GAS 的免疫组化染色结果为 CK7、MUC6、PAX-8 CEA 和 P53(野生型)阳性,CDX2、CK20、ER、PR、P16 和 WT1 阴性。增殖指数(Ki-67)为 20%。鳞状细胞癌的免疫组化染色显示 P16 和 P53(野生型)阳性,增殖指数(Ki-67)为 90%。然而,GAS 的发病机制和分子机制尚未完全阐明。随着更多病例的发现和报告,可以开发更多的靶向疗法并在这些患者中进行测试。

Abstract: Gastrointestinal angiosarcoma is an extremely rare malignant tumor of the digestive tract, characterized by a very poor prognosis, with few patients surviving more than 1 year after diagnosis. This case report describes a 71-year-old female patient with a 3-year history of intermittent abdominal pain and significant exacerbation of abdominal pain and bloating 2 weeks prior to treatment. After surgical treatment, the pathological and immunohistochemical diagnosis was primary epithelioid angiosarcoma of the jejunal mesentery. The patient refused postoperative adjuvant chemotherapy and died 4 months after diagnosis due to widespread systemic metastasis. In addition, this article reviews 38 previously reported cases of primary gastrointestinal angiosarcoma, aiming to further understand angiosarcoma and thus guide clinical practitioners in providing more comprehensive treatment approaches.

Abstract: Tumor microenvironment (TME) is a complex and integrated system containing a variety of tumor-infiltrating immune cells and stromal cells. They are closely connected with cancer cells and influence the development and progression of cancer. Traditional Chinese medicine (TCM) is an important complementary therapy for cancer treatment in China. It mainly eliminates cancer cells by regulating TME. The aim of this review is to systematically summarize the crosstalk between tumor cells and TME, and to summarize the research progress of TCM in regulating TME. The review is of great significance in revealing the therapeutic mechanism of action of TCM, and provides an opportunity for the combined application of TCM and immunotherapy in cancer treatment.

Keywords: cancer, tumor microenvironment, traditional Chinese medicine, anti-tumor effects
