RESUMEN
OBJECTIVES: This study investigates the dual role of ALKBH5, an eraser enzyme, in colorectal cancer (CRC), focusing on how N6-methyladenosine (m6A) mutations influence CRC development and progression. METHODS: We reviewed various studies that highlighted the role of ALKBH5 in colorectal cancer (CRC). This includes the impact of ALKBH5 on tumor cell behavior including immune system interactions, invasion, and proliferation in CRC. We also looked into how ALKBH5 acts as a tumor suppressor under different conditions analyzed clinical data to assess the impact of ALKBH5 expression on outcomes in colorectal cancer patients. KEY FINDINGS: In CRC, ALKBH5 plays a dual role. In certain situations, it inhibits the progression of the tumor, but in other circumstances, it promotes tumor growth and immunosuppression. The interaction with RABA5 plays a role in the development of CRC. Having elevated levels of ALKBH5 has been associated with unfavorable patient outcomes, such as reduced survival rates and more advanced cancer stages. Various factors, including tumor differentiation, TNM stages, and carcinoembryonic antigen (CEA) levels, be linked to ALKBH5 expression. CONCLUSIONS: ALKBH5 plays a complicated and situation-specific role in colorectal cancer (CRC). Targeting ALKBH5 could result in novel therapy options that balance its tumor-promoting and tumor-fighting properties in CRC. Further research into m6A alterations and ALKBH5 could enhance CRC treatment approaches and patient outcomes.
RESUMEN
The Zigzag ladybird beetle, Cheilomenes sexmaculata (Fabricius) (Coleoptera: Coccinellidae), is a biological control agent that feeds on a variety of aphid species. Life table and predation data of C. sexmaculata were collected under laboratory conditions at 25±2°C, 60±5% RH and L14: D10 h in connection with feeding on four different aphid species; Lipaphis erysimi (Kaltenbach), Myzus persicae (Sulzer), Aphis nerii (Boyer de Fonscolombe) and Diuraphis noxia (Mordvilko). Larval development of C. sexmaculata was long when fed on M. persicae (12.18 days) and shorter on D. noxia (10.64 days). The male's lifespan was longer on M. persicae (26.70 days) and shorter on L. erysimi (23.67 days). Fecundity was maximum when the beetle was fed D. noxia (316.8 eggs/female) and minimum on M. persicae (199.1 eggs/female). Net reproductive rate, intrinsic rate of increase and finite rate of increase were highest on D. noxia with values of 158.4 (offspring individual-1), 0.22 d-1, and 1.24 d-1, respectively whereas the respective parameters were lowest on L. erysimi (99.5 offspring individual-1, 0.19 d-1, and 1.20 d-1, respectively). However, the mean of the generation (T) was shorter on A. nerii (22.48 d-1) and longer on M. persicae (24.68 d-1). Based on life table parameters obtained under laboratory conditions, the most appropriate host of C. sexmaculata was D. noxia. This study should help us to improve mass rearing and use of C. sexmaculata in the biological control of aphids on field and horticultural crops.
