Abstract
Background This study describes the epidemiological pattern of acute hepatitis B virus (HBV) infection in Saudi Arabia from 2006 to 2021. It explores case frequency and the crude incidence rate (CIR) by year of diagnosis, age group, region, gender, and nationality of patients. Methods Retrospective data on acute hepatitis B cases diagnosed across 20 regions of Saudi Arabia during January 2006 to December 2021 were obtained from the Saudi Ministry of Health's Statistical Yearbook. Statistical analyses were conducted using SPSS version 20.0, employing both parametric and non-parametric tests. Results The highest CIR was reported in the regions of Qunfudah, Jeddah, Tabuk, and Taif (28.6, 25.2, 25.1, and 23.4 per 100,000 people). In contrast, the lowest CIR was documented in the regions of Hail, Qurayyat, Jouf, and Hafr AL-Baten (3.6, 3.5, 2.9, and 1.2 per 100,000 people). Incidence rates were notably elevated in those aged 45 years and above (30.6 per 100,000 individuals), followed by the 15-44 age group (14.2 per 100,000 individuals), and were lowest in children aged 0-14 years (0.8 per 100,000 individuals). Regarding gender differences, HBV infection rates were 1.4 times higher in Saudi males than females and 2.2 times higher in non-Saudi males compared to females. Overall, Saudi nationals had a 4.2 times higher HBV infection rate than non-Saudis during the study period. Conclusion This study highlights diverse acute Hepatitis B infection rates across Saudi regions, with higher rates in Qunfudah, Jeddah, Tabuk, and Taif, and lower rates in Hail, Qurayyat, Jouf, and Hafr AL-Baten. Predominance among ages 45+, followed by 15-44, and lowest in 0-14 age groups was observed. Gender variations showed notably higher rates in Saudi and non-Saudi males. The notably higher prevalence among Saudi nationals implies key considerations for public health strategies.

Abstract
It has been estimated that 15%-20% of human cancers are attributable to infections, mostly by carcinogenic viruses. The incidence varies worldwide, with a majority affecting developing countries. Here, we present a comparative analysis of virus-positive and virus-negative tumors in nine cancers linked to five viruses. We find that virus-positive tumors occur more frequently in males and show geographical disparities in incidence. Genomic analysis of 1,658 tumors reveals virus-positive tumors exhibit distinct mutation signatures and driver gene mutations and possess a lower somatic mutation burden compared to virus-negative tumors of the same cancer type. For example, compared to the respective virus-negative counterparts, virus-positive cases across different cancer histologies had less often mutations of TP53 and deletions of 9p21.3/ CDKN2 A- CDKN1A ; Epstein-Barr virus-positive (EBV+) gastric cancer had more frequent mutations of EIF4A1 and ARID1A and less marked mismatch repair deficiency signatures; and EBV-positive cHL had fewer somatic genetic lesions of JAK-STAT, NF-κB, PI3K-AKT and HLA-I genes and a less pronounced activity of the aberrant somatic hypermutation signature. In cHL, we also identify germline homozygosity in HLA class I as a potential risk factor for the development of EBV-positive Hodgkin lymphoma. Finally, an analysis of clinical trials of PD-(L)1 inhibitors in four virus-associated cancers suggested an association of viral infection with higher response rate in patients receiving such treatments, which was particularly evident in gastric cancer and head and neck squamous cell carcinoma. These results illustrate the epidemiological, genetic, prognostic, and therapeutic trends across virus-associated malignancies.

Abstract
Liver cirrhosis represents an advanced stage of chronic liver disease and is associated with significant morbidity, mortality, and risk of cancer development. While sex disparity of liver diseases has been observed, understanding at a genetic level awaits more thorough investigation. In this study, we performed a sex-specific analysis of the microRNA (miR) profiles in hepatitis B virus (HBV)-associated cirrhosis by small RNA-sequencing using clinical tissue samples. Potential associated signaling pathways, downstream gene targets, and upstream regulators were highlighted by computational prediction analyses based on the differentially expressed miRs (DEmiRs). From our results, deregulation of miRs in cirrhosis showed a marked difference between males and females by the degree and pattern. Sixty-five (64 up-regulated, 1 down-regulated) and 12 (6 up-regulated, 6 down-regulated) DEmiRs were found in males and females, respectively, when compared with their respective control group. A number of DEmiRs were only observed in one sex but not the other. In addition, 26 DEmiRs were identified between cirrhosis female and cirrhosis male groups. Fatty acid biosynthesis pathway, extracellular matrix-receptor interaction, p53 signaling, Hippo signaling, tumor necrosis factor signaling, the forkhead box O signaling, as well as gene targets ribosomal protein S27 like, methyl CpG binding protein 2, and estrogen receptor 1, may contribute to the pathogenesis and biological behavior of cirrhosis in a sex-specific manner. Analysis of the Cancer Genome Atlas data set suggested a role of sex-specific DEmiRs in multistep hepatocarcinogenesis. Conclusion: Our findings illustrate that miR profiles in HBV-associated cirrhosis are distinct between the males and females and suggest a potential role of sex-specific biomarkers and molecular mechanisms in disease development and progression.

Abstract
Postmenopausal women with hepatitis B virus (HBV) infection are more likely to have accelerated liver fibrosis, eventually advancing to liver cirrhosis or hepatocellular carcinoma (HCC). The association between sex hormones and HBV-related HCC risk is unclear. We investigated whether hormone replacement therapy (HRT) is beneficial to postmenopausal women with HBV infection. This retrospective study selected the data of 44,465patients with HBV infection between January 2000 and December 2018 from Taiwan’s National Health Insurance Research Database. After excluding patients with preexisting liver diseases, liver cirrhosis, or liver malignancies, we grouped the remaining 10,474 patients by whether they had undergone HRT for at least 3 months (n = 5,638) and whether they had not received HRT (n = 4,836). After propensity score matching, we assigned 3080 patients to an HRT cohort and matched them (1:1) with those in a non-HRT cohort. The incidence of HCC (P < 0.022) and all-cause mortality rate (P < 0.001) were lower in the HRT cohort than in the non-HRT cohort. The liver cirrhosis risk was not significantly higher in the HRT cohort (P = 0.355). HRT is associated with reduced HCC risk and improved survival outcomes but is unrelated to liver cirrhosis development in postmenopausal women.

Abstract
Small ubiquitin-like modifier proteins are involved in tumorigenesis; however, the potential effects and functions of the family member ubiquitin-like modifier-activating enzyme 2 (UBA2) on colorectal cancer are not clear. The present study aimed to examine the effects of UBA2 on the proliferation of colorectal cancer cells in vitro and in vivo. The mRNA and protein expression levels of UBA2 in patients with colorectal cancer were measured by reverse transcription-quantitative polymerase chain reaction and immunohistochemistry, respectively. UBA2 expression levels in colorectal cancer tissues were significantly increased compared with the paracancerous normal tissues. The expression of UBA2 was also associated with higher stage colorectal cancer and poor prognosis. MTT and colony formation assays were used to examine proliferation in colorectal cancer cell lines. Flow cytometry was performed to examine the effects of UBA2 on the cell cycle and apoptosis of colorectal cancer cell lines and protein expression levels were examined by western blotting. Athymic nude mice were used to examine the ability of transfected colorectal cancer cells to form tumors in vivo. Downregulation of UBA2 inhibited the proliferation of colorectal cancer cell lines in vitro and in vivo through the regulation of cell cycle associated protein expression and apoptosis. Furthermore, downregulation of UBA2 decreased the expression levels of cyclin B1, B-cell lymphoma-2, phosphorylated protein kinase B and E3 ubiquitin-protein ligase MDM2 in colorectal cancer cells, whereas the expression levels of p21 and p27 were increased. UBA2 was demonstrated to serve an essential role in the proliferation of colorectal cancer and may be used as a potential biomarker to predict prognosis and as a therapeutic target in colorectal cancer.

Abstract
On the global scale, hepatitis B virus (HBV) infection is the main cause of hepatocellular carcinoma (HCC) especially in regions of Asia where HBV infection is endemic. Epidemiological studies show that the incidence of inflammation-driven HCC in males is three times as high as in females. Recent studies suggest that sex hormones have a crucial role in the pathogenesis and development of HBV-induced HCC. We found that the estrogen/androgen signaling pathway is associated with decreased/increased transcription and replication of HBV genes and can promote the development of HBV infections by up/downregulating HBV RNA transcription and inflammatory cytokines levels, which in turn slow down the progression of HBV-induced HCC. Additionally, sex hormones can also affect HBV-related HCC by inducing epigenetic changes. The evidence that both morphology and function of the human liver are affected by sex hormones was found over 60 years ago. However, the underlying molecular mechanism largely remains to be elucidated. This review focuses mainly on the molecular mechanisms behind the sex difference in HCC associated with HBV and other factors. In addition, several potential treatment and therapeutic strategies for inflammation-driven HCC will be introduced in this review.

Abstract
Ubiquitin-proteasome system regulates cell proliferation, apoptosis, angiogenesis, and motility, which are processes with particular importance for carcinogenesis. UBA protein 2-like protein (UBAP2L) was found to be associated with proteasome; however, its biological function is largely unknown. In this study, the mRNA levels of UBAP2L in human normal and colorectal carcinoma tissues were analyzed using the datasets from the publicly available Oncomine database ( www.oncomine.org ) and found UBAP2L was overexpressed in colorectal carcinoma tissues. Furthermore, we elucidated the role of UBAP2L in human colorectal cancer via an RNA interference lentivirus system in three colorectal carcinoma cell lines HCT116, SW1116, and RKO. Knockdown of UBAP2L led to suppressed cell proliferation and impaired colony formation. UBAP2L depletion in HCT116 and RKO cells also induced cell cycle arrest as well as apoptosis. Moreover, the phosphorylation of PRAS40, Bad, and the cleavage of PARP were remarkably increased after UBAP2L knockdown by Intracellular signaling array and also the activation of P38 was obviously decreased and the cleavage of Caspase 3 and Bax were increased after UBAP2L silencing by western blot assay, indicated that UBAP2L might be involved in the cell growth by the regulation of apoptosis-related proteins. Our findings indicated that UBAP2L may be essential for colorectal carcinoma growth and survival. Lentivirus-mediated small interfering RNA against UBAP2L might serve as a potential therapeutic approach for the treatment of colorectal cancer.

Abstract
To the best of our knowledge, none of the prognostic staging systems for hepatocellular carcinoma (HCC) patients who underwent sorafenib therapy is universally adopted or preferred. In the present study, we aimed to compare prognostic ability among five prognostic systems, including the Japan Integrated Staging (JIS) system, the Barcelona Clinic Liver Cancer classification system, the tumor-node-metastasis classification system, the Cancer of the Liver Italian Program scoring system and the Chinese University Prognostic Index (CUPI) scoring system for HCC patients who received sorafenib therapy. A total of 143 HCC patients treated with sorafenib were analysed. We compared prognostic ability among the five prognostic systems using the likelihood ratio (LR) χ2 test, linear trend χ2 test and concordance index (c-index). Our cohort included 114 men and 29 women. The median patient age was 71 years (range, 45-89 years). A total of 102 patients were classified as Child-Pugh A and 41 as Child-Pugh B, whereas 31 patients (21.7%) had portal vein invasion and 63 (44.1%) extrahepatic metastases. The median survival time was 6.9 months. In the LR χ2 test, the CUPI scoring system had the highest value (35.804), followed by the JIS system (17.469). In the linear trend χ2 test, the CUPI scoring system had the highest value (17.523), followed by the JIS system (15.819). In addition, the JIS system had the highest value in the 6-month c-index (0.659) as well as in the 1-year c-index (0.674). However, the CUPI classification system had the lowest value in the 1-year c-index (0.590). In conclusion, the JIS system may be an appropriate staging system for HCC patients undergoing sorafenib therapy.

Abstract
Ubiquitin-associated protein 2-like (UBAP2L), which contains a ubiquitin-associated (UBA) domain near its N-terminus, has been indicated in the pathogenesis of several human cancers, including multiple myeloma, hepatocellular carcinoma and malignant ovarian tumors. However, the role of UBAP2L in human glioma remains unknown. In the present study, UBAP2L was widely expressed in multiple glioma cell lines. To further examine the effects of UBAP2L on glioma growth, lentivirus-mediated short hairpin RNA (shRNA) was employed to knockdown UBAP2L expression in the glioblastoma cell lines. Depletion of UBAP2L significantly inhibited the proliferation and colony formation ability, as determined by MTT and colony formation assays. Cell cycle analysis showed that UBAP2L knockdown induced G0/G1 phase arrest in U251 and U373 cells, while S phase arrest was induced in A172 cells. These results suggest that UBAP2L has a key role in glioma cell growth, and may act as an oncogene to promote malignant glioma development.

Abstract
Infection with hepatitis B virus (HBV) is a major risk factor for hepatocellular carcinoma (HCC) in developed countries. Epidemiological reports indicate that the incidence of HBV-related HCC is higher in males and postmenopausal females than other females. Increasing evidence suggests that sex hormones such as androgens and estrogens play an important role in the progression of an HBV infection and in the development of HBV-related HCC. While androgen is supposed to stimulate the androgen signaling pathway and cooperate to the increased transcription and replication of HBV genes, estrogen may play a protecting role against the progression of HBV infections and in the development of HBV-related HCC through decreasing HBV RNA transcription and inflammatory cytokines levels. Additionally, sex hormones can also affect HBV-related hepatocarcinogenesis by inducing epigenetic changes such as the regulation of mRNA levels by microRNAs (miRNAs), DNA methylation, and histone modification in liver tissue. This review describes the molecular mechanisms underlying the gender disparity in HBV-related HCC with the aim of improving the understanding of key factors underneath the sex disparity often observed in HBV infections. Furthermore, the review will propose more effective prevention strategies and treatments of HBV-derived diseases.

Abstract
Chronic hepatitis B virus (HBV) infection is one of the most common causes of hepatocellular carcinoma (HCC), a malignant tumor with high mortality worldwide. One remarkable clinical feature of HBV-related HCC is that its incidence is higher in males and postmenopausal females compared to other females. Increasing evidence indicates that HBV-associated HCC may involve gender disparity and that it may be a type of hormone-responsive malignant tumor. Sex hormones, such as androgen and estrogen, have been shown to play very different roles in the progression of an HBV infection and in the development of HBV-related HCC. Through binding to their specific cellular receptors and affecting the corresponding signaling pathways, sex hormones can regulate the transactivation of HBx, cause the chronic release of inflammatory cytokines in the hepatocellular microenvironment, and participate in epigenetic and genetic alternations in hepatocytes. All of these functions may be related to the initiation and progression of HBV-associated HCC. A thorough investigation of the molecular mechanisms underlying the gender-related disparity in HBV-related HCC should provide a new perspective for better understanding its pathogenesis and exploring more effective methods for the prevention and treatment of this disease.
