Handling procedures

Initial handling guidelines

Upon arrival, the vial should be stored in liquid nitrogen vapor phase and not at -80°C. Storage at -80°C may result in loss of viability.

1. Thaw the vial in 37°C water bath for approximately 1-2 minutes.
2. Transfer the cell suspension (0.8 mL) to a 15 mL/50 mL conical sterile polypropylene centrifuge tube containing 8.4 mL pre-warmed culture medium, wash vial with an additional 0.8 mL culture medium (total volume 10 mL) to collect remaining cells, and centrifuge at 201 x g (rcf) for 5 minutes at room temperature. 10 mL represents minimum recommended dilution. 20 mL represents maximum recommended dilution.
3. Resuspend the cell pellet in 5 mL pre-warmed culture medium and count using a haemocytometer or alternative cell counting method seed all remaining cells into a T25.
4. Incubate the culture at 37°C incubator with 5% CO2. Check the culture one day after revival and continue to check until 80% confluent. Media change can be given if needed.
5. Once confluent passage into an appropriate flask at a density of 2x104 cells/cm2. Seeding density is given as a guide only and should be scaled to align with individual lab schedules. Cultures should be monitored daily.

Subculture guidelines
  • All seeding densities should be based on cell counts gained by established methods.
  • A guide seeding density of 2x104 cells/cm2 is recommended.
  • Cells should be passaged when they have achieved 80-90% confluence.
Culture medium

DMEM (High Glucose) + 10% FBS

Cryopreservation medium

Cell Freezing Medium-DMSO Serum free media, contains 8.7% DMSO in MEM supplemented with methyl cellulose.

Supplementary information

REXO4 also known as RNA exonuclease homolog 4 is a protein that plays a role in RNA processing. It has a molecular mass of approximately 33 kDa. REXO4 is found in the nucleolus and also distributes within the cytoplasm. This protein exhibits exonuclease activity participating in the degradation and/or processing of RNA molecules. By cutting RNA molecules it facilitates the regulation of gene expression which is important for proper cellular function and growth.
Biological function summary

RNA exonucleases like REXO4 contribute to RNA surveillance processes that maintain the quality of RNA. REXO4 might function as part of a larger complex tasked with the maturation and degradation of RNA. These activities are essential especially in the context of removing faulty RNA molecules that could cause deleterious effects if left unchecked in the cell. The precise role of REXO4 remains under investigation yet its contributions to the RNA life cycle are noteworthy.

Pathways

RNA processing and degradation involve REXO4 in essential molecular interactions. It participates in the RNA degradation pathway where it contributes to the turnover of RNA molecules ensuring cellular stability and homeostasis. This pathway often intersects with the nonsense-mediated decay pathway a critical quality control mechanism. Proteins such as UPF1 which are involved in the nonsense-mediated decay pathway might be functionally connected to REXO4 highlighting its importance in maintaining cellular RNA integrity.

Defects or dysregulation in the function of REXO4 may contribute to RNA-related conditions. Aberrant RNA processing has connections to disorders such as cancer. In certain cancers malfunctioning RNA degradation can lead to uncontrolled cell proliferation. Moreover faulty REXO4 activity might impact neurodegenerative diseases by affecting neuronal RNA metabolism. Interactions with proteins like TARDBP associated with such neurodegenerative disorders suggest that REXO4 may have broader implications in understanding RNA-linked diseases.
