Clear cell renal cell carcinoma (ccRCC) represents the most common subtype of renal cell carcinoma, accounting for nearly 70–90% of cases and the majority of metastatic RCC worldwide. Despite advances in surgery and immunotherapy, metastatic ccRCC remains challenging to treat and accounts for the majority of RCC-related deaths. A hallmark of ccRCC biology is dysregulated hypoxia signaling, largely driven by loss of the tumor suppressor VHL, which leads to accumulation of hypoxia-inducible factors (HIFs) and activation of downstream oncogenic pathways.
Recent studies have turned attention to doublecortin-like kinase 1 (DCLK1), a serine/threonine kinase and recognized marker of cancer stem cells. DCLK1 is known to confer stem-like characteristics on tumor cells, thereby enhancing their capacity for proliferation, invasion, and metastasis. However, the mechanisms regulating its expression and the therapeutic implications of targeting DCLK1 have remained poorly defined.

Over the past decade, the CRISPR-Cas9 system has transformed genetic engineering by offering a precise and efficient way to modify genomes. While knockout strategies—where gene function is disrupted by introducing frameshift mutations—are widely used, the ability to knock in defined DNA sequences has unlocked even greater potential. CRISPR knock-in technology enables the insertion of point mutations, fluorescent tags, selectable markers, or entire genes into endogenous loci, providing powerful tools for disease modeling, therapeutic development, and functional genomics.

Delivering genetic material into mammalian cells is a central step in modern molecular biology, yet the choice of method often determines whether an experiment succeeds or fails. While adherent cells are generally receptive to chemical transfection reagents or electroporation, suspension cell types—such as lymphocytes, T-cell leukemia lines, and hematopoietic progenitors—are notoriously resistant. Their lack of adhesion, tendency to aggregate, and negatively charged membrane surface reduce the effectiveness of conventional methods.
In these cases, lentiviral transduction has become the preferred strategy. Lentiviruses, members of the retrovirus family, possess the ability to infect both dividing and non-dividing cells and to integrate their genetic cargo stably into the host genome. This combination of high efficiency, stable expression, and broad tropism makes them especially well suited for suspension cells.

Gene knockout (KO) technology has become one of the most widely used approaches in modern molecular biology. By completely disrupting the function of a target gene, researchers can explore its role in cellular pathways, disease progression, and drug responses. Although the advent of CRISPR-Cas systems has significantly simplified the process, generating a robust KO cell line still requires careful planning and optimization. From sgRNA design to validation, every step influences the final outcome.
This article provides a comprehensive overview of strategies to optimize gene knockout experiments, highlights common pitfalls, and offers practical recommendations for ensuring reliable results.

CRISPR screening has become a cornerstone of functional genomics, allowing researchers to investigate gene function at scale and uncover mechanisms behind complex biological processes. While experimental design is critical, the real challenge often begins once the sequencing data are generated. From read mapping to hit identification, each analytical step carries nuances that can affect the final interpretation. This article highlights common challenges in CRISPR screening analysis and provides practical guidance on how to address them.
