Gastric cancer (GC) is diagnosed at advanced stages and has high mortality rates. Surgical resection and adjuvant chemotherapy are the main therapeutic approaches for GC. Despite curative resection, recurrence and metastasis contribute to a high mortality rate in patients with GC. The receptor-tyrosine-kinase-like orphan receptors 1/2 (ROR1/2) are transmembrane proteins belonging to the receptor tyrosine kinase (RTK) family. ROR1 and ROR2 are known to overexpress in the tumor tissues from several types of cancer patients. However, the role of RORs in the prognosis has not been understood.
This study aimed to determine the association of mRNA expression of ROR1, ROR2, and their signaling components WNT5A, NKX2-1, and FOXF1, with the survival outcome of GC patients. We performed Kaplan-Meir survival analysis on publicly available 'The Cancer Genome Atlas (TCGA)' data sets using 'Kaplan-Meir Plotter.'
High mRNA expression of ROR1, ROR2, NKX2-1, and FOXF1 was significantly correlated with worse overall survival (OS) of GC patients. Interestingly ROR1 and ROR showed a prognostic role in the intestinal subtype, but not in the diffuse subtype of GC. Furthermore, ROR1 was positively correlated with regulatory T cells and M2-type macrophages and negatively correlated with Th17 and natural killer T cells in the tumor stroma of patients with GC.
We conclude that the expression of ROR1, ROR2, and their associated genes correlate with worst prognosis of GC patients, particularly in the intestinal type.<br />.

Oral cancer is one of the most common malignancies in developing countries, but studies using global data are scarce. Telotristat Etiprate The aim of this study is to analyze the search interests for oral cancer using mouth cancer, tongue cancer, gum cancer, and lip cancer as common keywords.
Internet searches relating to oral cancer from 2010 to 2020, from 250 countries and dependent areas, were retrieved from Google Trends. Color densities in a heat map were used to show geographic differences. Kruskal-Wallis test with post hoc Dunn's analysis was used to perform yearly comparisons of searches for mouth cancer, tongue cancer, gum cancer, and lip cancer. Search results within 2020 were also compared to determine differences. Forecasting searches from 2021 to 2022 were done by fitting time series models.
From 29 of 250 (11.6%) countries, the highest search values were observed for mouth cancer in Sri Lanka, Qatar, Bangladesh, Finland, Netherlands, Spain, and France. Compared to 2020, greater searches were seen in 2018 (Mdn = 91%, P = 0.023) and 2019 (Mdn = 94%, P = 0.012) for mouth cancer, and 2019 (Mdn = 17%, P = 0.035) for lip cancer. The relative search volumes for gum cancer and lip cancer were substantially lower than mouth cancer during the COVID-19 pandemic.
Higher-income countries tend to be more interested in seeking information about oral cancer. Noteworthy decline in the interest in seeking information online for oral cancer may have crucial implications during the COVID-19 pandemic. Google Trends offer an invaluable and inexpensive means for oral cancer surveillance and health-seeking behavior.<br />.

Family Caregivers (FCs) of advanced cancer patients often suffer from caregiving burden due to stress arising from the responsibility of caregiving. link2 During the course of their patients palliative therapy, FCs quality of life seems to be influenced by their satisfaction with the quality of patient care. In this study, caregiving burden of FCs and their satisfaction with dedicate Inpatient palliative care (IPC) services provided to their patients were studied.
This cross-sectional study assessed 211 FCs of advanced cancer patients. Caregiving burden of FCs and their satisfaction with IPC were studied through Zarith Burden Interview (ZBI-12 version) and Family Carer Satisfaction with Palliative Care scale (FAMCARE-2) questionnaires, respectively. Descriptive and correlation analyses were deployed for data analysis.
The summative mean ZBI-12 score for FCs was 20.26±5.92, suggesting moderate to high caregiving burden among FCs. Significantly higher scores were observed among FCs who belonged to below poverty line (BPL) families(p=0.025), revealing higher caregiving burden among this lower income group. FCs who were male, unmarried, unemployed, and residing in rural experienced higher caregiving burden. However, it did not lead to a statistically significant difference. The summative mean FAMCARE-2 scale scores was 74.01±4.34, which suggested FCs high satisfaction with the palliative care services provided to their patients. FAMCARE-2 scale scores were lower for BPL families, but it was not statistically significant.
FCs from lower-income groups experienced higher caregiving burden. It seems that IPC unit provided satisfactory services to advanced cancer patients, leading to enhancement of FCs satisfaction and consequently quality of life.<br />.

Alterations in common DNA repair genes (RAD51 and XRCC2) may lead to cervical cancer (CC) development. In the present study, we analyzed the association between RAD51 rs1801320 and XRCC2 rs3218536 polymorphisms and CC.
Variants were selected based on their associations with some cancers in several ethnicities and the risk allele frequency (>0.05) in different populations. The variants were detected using the PCR-RFLP method. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were determined by logistic regression models.
Significantly increased risk (p <0.05) were detected for both SNPs with CC (rs1801320- GC vs. GG aOR=2.21, 95% CI=1.43-3.42; CC vs. GG aOR=4.48, 95% CI=1.76-11.42; dominant model aOR=2.49, 95% CI=1.65-3.76; recessive model aOR=3.52, 95% CI=1.40-8.88; allele model OR=2.30, 95% CI=1.63-3.26, and rs3218536- GA vs. GG aOR=2.77, 95% CI=1.85-4.17; AA vs. GG aOR=5.86, 95% CI=2.08-16.50; dominant model aOR=2.97, 95% CI=1.99-4.42; recessive model aOR=3.56, 95% CI=1.30-9.73; and allele model aOR=2.21, 95% CI=1.62-3.00). Besides, older patients (>60 years) with rs1801320 showed significantly reduced risk (OR=0.53, 95% CI=0.29-0.96, p=0.04) but with rs3218536 depicted significantly increased risk (aOR=2.44, 95% CI=1.20-4.96, p=0.01) for CC.
This study indicates an association of rs1801320 and rs3218536 polymorphisms with CC and confirms that patients older than 60 years are more likely to develop CC for rs3218536 polymorphism.

Epigenetic alterations play an important role in tumorigenesis. Hypermethylation of CpG islands within the promoter regions of tumor suppressor genes (TSGs) and histone deacetylation lead to the silencing of the genes resulting in cancer induction. The suppressor of cytokine signaling (SOCS) family is an important negative regulator of cytokine signaling and deregulation of this family has been reported in several cancers, the protein of the SOCS family inhibit the cytokine-activated Janus kinase/signal transducers and activators of transcription (JAK/STAT) signaling pathway to modulate cellular responses. Previously, we evaluated the effects of DNA demethylating agents and histone deacetylase inhibitors on hepatocellular carcinoma (HCC). The current study aimed to investigate the effect of decitabine (5-aza-2'-deoxycytidine, 5-aza-CdR) in comparison to vorinostat (suberoylanilide hydroxamic acid, SAHA) on DNMT1, DNMT3a and DNMT3b, HDAC 1-3, SOCS 1, SOCS 3, JAK2, and STAT3 gene expression, cell growth inhibition, and apoptosis induction of HCC HLE and LCL-PI 11 cell lines.
The HLE and LCL-PI 11 cells were treated with 5-aza-CdR and SAHA and then the MTT assay, flow cytometry assay, and quantitative real-time RT-PCR were achieved to determine cell viability, cell apoptosis, and relative gene expression respectively.
The result indicated that both compounds inhibited cell growth, induced apoptosis, and down-regulated DNMT1, DNMT3a DNMT3b, HDAC 1-3, JAK2, and STAT3 and up-regulated HDAC 1-3, SOCS 1, and SOCS 3 genes expression significantly. The apoptotic effect of SAHA was stronger than that of 5-Aza-CdR.
5-Aza-CdR and SAHA can induce cell growth inhibition and apoptosis induction through the JAK/STAT pathway.

Triple-negative breast cancer accounts for approximately 15-20% of all breast carcinomas and is associated with earlier age of onset, aggressive clinical course, and dismal prognosis. A series of 1,3-diaryl-5-(3,4,5-trimethoxyphenyl)-4,5-dihydro-1 H-Pyrazole and 1,3-diaryl-5- (3,4,5-trimethoxyphenyl)- 1 H-Pyrazole were evaluated for their anticancer activity against MDA-MB-468, human triple negative breast cancer cell line.
The cytotoxic effects of Pyrazole derivatives on the growth of MDA-MB-468 and AGO1522 were determined using MTT assay. Annexin-V-FITC and PI staining were performed to detect apoptosis and cell cycle distribution using Flow cytometry. The level of Reactive oxygen species (ROS) formation and caspase 3 activity were determined accordingly.
Pyrazole derivatives induced a dose and time-dependent cell toxicity in MDA-MB-468 compared with untreated cells. The results showed that 3-(4-methoxyphenyl)-1-(p-tolyl)-5-(3,4,5-trimethoxyphenyl)-4,5-dihydro-1H-Pyrazole (3f) was the most active compound with IC50 values 14.97 μM and 6.45 μM compared with Paclitaxel with IC50 values 49.90 μM and 25.19 μM, after 24 and 48 hours, respectively. Upon treatment with 14.97 μM of 3f after 24 h, the compound induced cell cycle arrest in S phase. 3f provoked apoptosis was accompanied by the elevated level of ROS and increased caspase 3 activity in MDA-MB-468 cells compared with untreated cells.
The overall results of the present study provided evidence for the cytotoxicity of compound 3f against MDA-MB-468 cells in comparison to reference standard, Paclitaxel. link3 It proves that compound 3f can trigger apoptosis through ROS production and caspase 3 activation. These bring supportive data for future investigations that will lead to their use in cancer therapy.<br />.

The association between PD-1, PD-L1, and PD-L2 expression and prognosis has been extensively studied in various cancers but remained controversial in breast cancer. Besides, little is known about the prognostic value of PD-1, PD-L1, and PD-L2 upregulation or downregulation following systemic therapy (chemotherapy and hormonal therapy) in breast cancer. Therefore, we aim to investigate the change of PD-1, PD-L1, and PD-L2 expression in mRNA level after primary systemic therapy in breast cancer patients and its clinical implications.
Expression of PD-1, PD-L1, and PD-L2 mRNA were measured before-after chemotherapy and hormonal therapy with real-time PCR in 80 advanced breast cancer patients. The correlation between alteration of PD-1, PD-L1, and PD-L2 expression and clinicopathological characteristics as well as overall survival was also statistically analyzed.
Chemotherapy and hormonal therapy altered PD-1, PD-L1, and PD-L2 expression in breast cancer with most patients have an increase expression. As much as 57.
