Radioresistance greatly hinders the treatment of nasopharyngeal carcinoma (NPC). Long noncoding RNA (lncRNA) plasmacytoma variant translocation 1 (
) has been corroborated to participate in diverse cancers, including NPC. Our aim was to investigate the underlying molecular mechanism of
in NPC radioresistance.

Quantitative real-time polymerase chain reaction (qRT-PCR) was utilized to measure the expression levels of
, microRNA
and phosphatidylinositol-4, 5-bisphosphate 3-kinase catalytic subunit alpha (
) in NPC tissues and cells. Cell counting kit-8 (CCK8) assay, colony formation assay and flow cytometry assay were employed to detect cell proliferation, radiosensitivity and apoptosis, respectively. The protein levels of Cyclin D1, B-cell lymphoma 2 associated X (Bax), Cleaved-caspase-3, PIK3CA, protein kinase B (AKT) and phosphorylated AKT (p-AKT) in samples were measured by Western blot. The starBase was used to predict the binding sites between

The purpose of this study was to prepare and characterize a lipid magnetic ball modified with KRAS antibodies on the surface and to isolate circulating tumor cells of colorectal cancer with
mutations.

The microemulsion method was used to form lipid bilayers to encapsulate Fe3O4 nanoparticles with superparamagnetism to form lipid magnetic balls, and
antibodies were formed on the surface to form
immune lipid magnetic balls.

Compared with traditional EpCAM antibody-modified lipid magnetic balls, it can effectively improve the capture ability of colorectal cancer circulating tumor cells with
mutation, the capture rate reaches 92.9%, and the capture results are consistent with clinical diagnosis and pathology.

Our results showed that
antibody-modified lipid magnetic balls can be used in the diagnosis and treatment of
colorectal cancer.

Dysregulated circular RNAs (circRNAs) are involved in the development of glioma. This paper aims to analyze the role and mechanism of circRNA tau tubulin kinase 2 (circ-TTBK2) in glioma progression.

The glioma samples and normal brain tissues were collected. The levels of circ-TTBK2, microRNA-1283 (miR-1283) and chromodomain helicase DNA-binding protein 1 (CHD1) were examined via quantitative reverse transcription polymerase chain reaction or Western blot. Cell proliferation, migration, invasion and glycolysis were determined via 3-(4, 5-dimethyl-2-thiazolyl)-2, 5-diphenyl-2-H-tetrazolium bromide, transwell assay, Western blot, glucose and lactate assay kits. The target relationship was analyzed via dual-luciferase reporter assay. The xenograft model was established using U251 cells.

circ-TTBK2 expression was increased in glioma tissues and cells. circ-TTBK2 knockdown suppressed glioma cell proliferation, migration, invasion and glycolysis. circ-TTBK2 was a sponge for miR-1283, and knockdown of miR-1283 reversed the effect of circ-TTBK2 silence on glioma progression. CHD1 was targeted via miR-1283, and miR-1283 repressed glioma cell proliferation, migration, invasion and glycolysis via decreasing CHD1. Knockdown of circ-TTBK2-reduced CHD1 expression by mediating miR-1283. Silence of circ-TTBK2 reduced xenograft tumor growth.

Down-regulation of circ-TTBK2 suppressed glioma development by regulating miR-1283 and CHD1, providing a new mechanism for understanding glioma pathogenesis.

Cancer has a major impact on the lives of family caregivers, including their health and quality of life (QOL). However, little is known about the QOL of family caregivers of adult cancer patients in Ethiopia. This study aimed to assess the QOL and associated factors among primary family caregivers of adult cancer patients in Addis Ababa, Ethiopia.

In this cross-sectional study, 291 family caregivers completed the survey in the Amharic language. The Caregiver Quality of Life Index-Cancer (CQOLC) was used to measure QOL of family caregivers. Descriptive and linear regression analyses were conducted using SPSS version 23.

The mean age of the family caregivers was 37.04±11.47 years and 51.5% were male. Endocrinology antagonist The mean score of QOL was 82.23 (±16.21). Not being employed in private sector (
= -0.128; CI=-7.82, -0.45;
= 0.028), having family monthly income less than 16 USD (
= 0.132; CI=0.87, 10.88;
= 0.021) and not having family monthly income greater than 64 USD (
= -0.128; CI= -10.43, -0.66;
= 0.026), being spouse (
= 0.179; CI 1.34, 11.99;
= 0.019) and not residing in urban areas (
= -0.139; CI -10.53, -0.96;
= 0.019) were negatively associated with the QOL of the family caregiver and explained 8.7% of the variation (
=0.087;
=0.000).

Our findings identified factors such as occupation, income, relationship with the patient, and place of residence that negatively associated with the QOL of family caregivers. Targeted interventions such as social and economic support and bringing the care to the patient's residence place are needed to improve the QOL of family caregivers of adult cancer patients.

Long non-coding RNA (lncRNA) exerts a regulatory role in the occurrence and progression of tumors. This study aimed at probing into the function and mechanism of lncRNA DICER1 antisense RNA 1 (DICER1-AS1) in colorectal cancer (CRC).

The expressions of DICER1-AS1, miR-296-5p and STAT3 mRNA were tested by quantitative real-time polymerase chain reaction (qRT-PCR). Cell counting kit-8 (CCK-8) assay was employed to detect cell proliferation, and Transwell was used to detect cell migration and invasion. In addition, the expressions of apoptosis-related proteins Bax and Bcl2 were detected by Western blot. Interactions between DICER1-AS1 and miR-296-5p, and miR-296-5p and STAT3 were predicted and determined by bioinformatics analysis, luciferase reporter assay and RNA binding protein immunoprecipitation (RIP) assay.

The expressions of DICER1-AS1 and STAT3 mRNA were significantly up-regulated while miR-296-5p expression was remarkably down-regulated in CRC tissues and cell lines. Over-expression of DICER1-AS1 or transfection of miR-296-5p inhibitors could promote the proliferation, migration and invasion and inhibit apoptosis of CRC cells, whereas knockdown of DICER1-AS1 or transfection of miR-296-5p mimics had the opposite effects.
