What are the Challenges in Transcriptomic Studies of Cancer?
While transcriptomics offers powerful insights, several challenges exist: 1. Heterogeneity: Tumors are often heterogeneous, containing various cell types with distinct transcriptomic profiles. 2. Complexity: The vast amount of data generated requires sophisticated bioinformatics tools for analysis. 3. Sample Quality: High-quality RNA samples are essential, but obtaining such samples from tumors can be difficult.
