Objective To investigate the effect of circular RNA hsa_circ_0001922 on the proliferation, migration and invasion of prostate cancer cell PC-3 and its underlying molecular mechanism. Methods qRTPCR and RNA FISH were used to detect the expression level and localization of hsa_circ_0001922 in PC-3 cells respectively. After hsa_circ_0001922 was targeted inhibited, clone formation, Transwell assay and scratch assay were used to detect the proliferation, migration and invasion abilities of PC-3 cells. qRT-PCR and Western blot were used to detect the expression levels of EMT pathway-related molecules after inhibiting hsa_circ_0001922. Results The expression of circular RNA hsa_circ_0001922 was increased in PC-3 cells (P<0.01) and it existed in the cytoplasm and nucleus. The invasion, migration and invasion abilities were significantly weakened (P<0.05) after inhibiting hsa_circ_0001922; the expression of E-cadherin mRNA increased (P<0.05) while the mRNA level of Vimentin decreased (P<0.05). The results of Western blot were consistent with the above (both P<0.05). Conclusion The circular RNA hsa_circ_0001922 may promote the proliferation, migration and invasion of PC-3 cells through the EMT pathway.

Cancer Research on Prevention and Treatment. 2022, 49 (07): 655-661.   DOI: 10.3971/j.issn.1000-8578.2022.21.1537
Abstract( 92 PDF (12351KB)  ( 53 ) )   HTML ()
Objective To reveal the mechanism of action of AS-IV on HepG2 cells based on molecular dynamics simulation and experimental evaluation. Methods We constructed a “drug-disease” network pharmacological map, analyzed the core genes of astragaloside IV (AS-IV) in HCC, screened key signaling pathways, and established a “drug-target” molecular dynamics model. In vitro assay was used to detect migration, proliferation and invasion abilities. Flow cytometry and qRT-PCR were used to detect the effect of AS-IV on the cell cycle and apoptosis, and the expression of core gene of HepG2. Results The core target of AS-IV acting on HCC was VEGFA. Compared with the control group, the high concentration of ASIV significantly inhibited the migration, invasion and proliferation of HepG2 cells, blocked the metastasis of HepG2 cells from G1 to G2 phase, promoted their apoptosis, down-regulated VEGFA expression and upregulated TGF-β1 expression. Conclusion AS-IV may inhibit the proliferation of hepatocellular carcinoma cells through multi-target and multi-pathway.

Abstract( 105 PDF (5891KB)  ( 49 ) )   HTML ()
Objective To investigate the expression of CK2α' in hepatocellular carcinoma (HCC) tissues and its prognosis value. Methods Tissue microarray was made from tumor and adjacent normal tissues of 83 patients with HCC. Immunohistochemical was used to stain the microarray for semi-quantitative analysis, and the expression of CK2α' in HCC tissues and adjacent normal tissues was compared. The associations between CK2α' expression and clinicopathologic features of HCC patients were analyzed with χ2 text. The prognostic value of CK2α' was estimated using Kaplan-Meier approach. Results The average positive expression rate of CK2α' was 47.8% in HCC and 65.4% in adjacent normal tissues. The positive expression rate of CK2α' in HCC tissues was lower than that in adjacent normal tissues (P<0.01). The expression level of CK2α' in the cancer tissues of 74.7% cases was significantly lower than that in the adjacent tissues. HCC patients with low CK2α' expression had higher risk of recurrence and shorter overall survival time (P<0.05). The expression of CK2α' was significantly correlated with CK19 (P<0.05). Conclusion CK2α' is down-regulated in HCC tissues and correlated with the prognosis of patients. It could be a potential prognostic marker for HCC.

Abstract( 133 PDF (9239KB)  ( 72 ) )   HTML ()
Objective To investigate the predictive value of depth of invasion (DOI) of tongue squamous cell carcinoma (TSCC) for cervical lymph node metastasis and prognosis. Methods We retrospectively analyzed the clinical and pathological data of 73 patients with T1/2 TSCC. ROC curve was used to determine the optimal cut-off value of DOI for predicting cervical lymph node metastasis, and logistic regression analysis was performed to analyze the related factors affecting cervical lymph node metastasis of TSCC. Kaplan-Meier method and Cox regression analysis were used for survival analysis. Results Among 73 patients, 18 patients were with lymph node metastasis and 55 patients were without lymph node metastasis. The median DOI with and without lymph node metastasis were 8.00 and 5.00 mm, respectively (P=0.003). The optimal cut-off value for DOI was 6.15 mm, with AUC 0.75 (95%CI: 64.1%~87.1%, P=0.001), sensitivity 77.8% and specificity 63.6%. DOI and pathological differentiation were independent prognostic factors for cervical lymph node metastasis in multivariate analysis. DOI, nerve invasion and pathological differentiation were independent prognostic factors of survival in Cox regression analysis. Conclusion DOI of TSCC patients has important predictive value for both cervical lymph node metastasis and prognosis. Neck lymph node dissection is recommended for patients with DOI>6.15 mm to improve survival rate and reduce recurrence rate.

Objective To investigate the effect of personality characteristics on near-term postoperative mental health of patients with laryngeal squamous cell carcinoma (LSCC). Methods We included 119 patients with LSCC who underwent surgical treatment. The recent psychological state was assessed by SCL-90, SAS and SDS 5 to 7 days after surgery. The EPQ was used to evaluate the personality characteristics of patients after operation. Multiple linear stepwise regression method was used to analyze the influencing factors of SAS and SDS scores of LSCC patients. Results The postoperative scores of SCL-90, SAS and SDS of LSCC patients were significantly higher than the Chinese norm (P0.05). The scores of P scale and N scale in EPQ were higher than the domestic norm (P<0.01). The scores of somatization, obsessiveness, anxiety, depression, hostility, phobia, paranoia and psychosis were significantly higher than the Chinese norm (P<0.05). Family income, surgical method, postoperative radiochemotherapy, psychoticism and neuroticism personalities were the influencing factors of postoperative SAS score (P<0.01). Family income, surgical method, postoperative radiochemotherapy, neurotic personality were the influencing factors of postoperative SDS score (P<0.01). Conclusion LSCC patients have near-term depression, anxiety and other psychological disorders after operation. In terms of personality, they have psychoticism and neuroticism. Family income, surgical methods, postoperative radiochemotherapy, psychoticism and neuroticism are independent risk factors affecting postoperative SAS and SDS scores.

Objective To retrospectively analyze the clinical data of 47 young NSCLC patients mutation style of EGFR and PD-L1 expression in tumor cells, to understand their clinicopathological and molecular characteristics. Methods We enrolled 47 young (40 years old) patients confirmed as NSCLC who underwent surgical resection, and 94 old patients (60 years old) were matched as 1:2 by R language. EGFR mutation status was detected by ARMS-PCR, and the expression of PD-L1 was detected by immunohistochemistry. Results The median age of 47 young patients with NSCLC was 37 years old. The disease was more common in women and the majority type was adenocarcinoma. In youth group, the 19del and 20ins were more frequent, but the exon 21 L858R point mutation proportion was higher in elder group. The expression of PD-L1 was significantly increased in the solid predominant histological subtype. The PD-L1 expression in 19del patients was higher than that in the patients with L858R mutation in youth group. Conclusion The majority of young NSCLC patients are female, nonsmokers and suffered from adenocarcinoma cancer. The proportion of EGFR alteration in 19del and 20ins in youth group is higher than that in elder group. The positive rate of PD-L1 expression in solid predominant histological subtype is higher than that with other subtypes. The expression of PD-L1 in young patients with EGFR 19del is higher than that with L858R.

Objective To explore the expression and significance of serum DKK1 in patients with gastric cancer. Methods We selected 170 gastric cancer patients (gastric cancer group) and 170 subjects with nongastric cancer during the same period (control group). ELISA was used to detect the DKK1 level. The ROC curve was used to evaluate the diagnostic performance, and we analyzed the relation between DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, TNM stage, infiltration depth, lymph node metastasis, liver metastasis, vascular invasion, perineural invasion. Results The serum DDK1 level in GC patients was higher than that in control group (P<0.0001). ROC curve showed that the possible optimal cut-off value of DKK1 for gastric cancer patients was 167.8 pg/ml, AUC was 0.908, sensitivity was 80.59%, and specificity was 84.71%. There was no significant relation between the serum DKK1 level and age, gender, family history of gastric cancer, cigarette smoking, alcohol consumption, tumor size, liver metastasis, vascular invasion or distant metastasis (all P>0.05). However, DKK1 level was significantly related with TNM stage, infiltration depth, lymph node metastasis and perineural invasion (all P<0.05). Conclusion Serum DKK1 level is higher in gastric cancer patients than that of control group and related with the severity of lesions, which indicates that serum DKK1 may be a potential biomarker for gastric cancer screening.

Chimeric antigen receptor T cell (CAR-T) is a kind of adoptive cell immunotherapy, in which T cells are genetically modified to exert targeted killing effect on tumors. CAR-T cell therapy has shown remarkable antitumor efficacy for the treatment of tumors, especially for hematological malignancies, but is less effective in solid tumors. Single-target CAR-T is prone to off-target effect during application, and there is a risk of relapse or more refractory treatment. The development of double-target or multi-target CAR-T is expected to extend the antigen coverage of target cells, effectively avoids antigen escape and prevents tumor recurrence, and prolongs the survival time of patients. This article reviews the advances of multi-target chimeric antigen receptor T cell, and discusses the prospect of its development.

Osteosarcoma is a malignant tumor with extreme invasiveness and metastasis as well as dismal prognosis. It is critical to rapidly find a unique therapy strategy capable of significantly improving the prognosis of osteosarcoma. Tumor immunotherapy has the potential to reawaken the immune system, restart and sustain the tumor-immune cycle in the body, resulting in the death of tumor cells. CD8+ CTL, CD4+ T cells, NK cells and NKT cells all play critical roles in tumor immunity, while humoral immunity may not only inhibit tumor growth but also enhance it. Researchers have devised various strategies to boost the immune system in recent years based on tumor immune response studies. This paper highlights and examines osteosarcoma immunotherapy from two perspectives: (1) boosting the response of patient’s own immune system to the tumor; (2) exogenously improving the patient’s immunological function.

The majority of diagnosed cases of gastric cancer are in the middle and late stages, while less than 10% of patients are diagnosed in the early stages in China. The standard treatment strategy for patients with progressive gastric cancer is surgery combined with postoperative adjuvant therapy or preoperative neoadjuvant followed by surgery combined with postoperative adjuvant therapy. Immunotherapy is now recognized as an innovative approach for cancers. It is worth exploring how to best use immunotherapy in neoadjuvant therapy to achieve better clinical benefit. Therefore, this paper reviews the progress of immunotherapy in neoadjuvant therapy for GC. Further studies and the understanding of immune system function by neoadjuvant therapy combined with immunotherapy will help to improve the treatment of gastric cancer.

Tumor-associated macrophages (TAMs) account for a large proportion in tumor stroma, and can be divided into M1 type (anti-tumoral) and M2 type (pro-tumoral). Recently, many experimental and clinical studies have shown that M2-type TAMs are significantly correlated with tumor stage, tumor cell differentiation, depth of invasion, angiogenesis, lymph node metastasis and therapeutic drug resistance, which eventually affects the prognosis of tumor patients. Targeted TAMs therapy is expected to benefit cancer
patients. This paper reviews the recent research of M2-type TAMs in lung cancer.

Alpha-fetoprotein producing gastric cancer (AFPGC) is a special type of gastric cancer. AFPGC is considered to be the most highly invasive tumor with a high degree of malignancy and prone to metastasis. As a consequence, it usually causes unsatisfied treatment effect and the prognosis is poor. At present, treatment methods and monitoring indicators have limited effect on AFPGC. VEGF, HER2, AFP, GPC3 and SALL4 are cogently associated with tumor genesis and development. If we can reasonably guide the treatment and prognosis of AFPGC patients, it will greatly improve the situation of patients and improve the survival of patients. This article reviews the research progress of the genes related to the treatment and prognosis of AFPGC.
