Acetylation, a critical regulator of diverse cellular processes, holds significant implications in various cancer contexts. Further understanding of the acetylation patterns of key cancer-driven proteins is crucial for advancing therapeutic strategies in cancer treatment. This study aimed to unravel the acetylation patterns of Engulfment and Cell Motility Protein 1 (ELMO1) and its relevance to the pathogenesis of colorectal cancer (CRC).

Methods: We quantified the number of TB by haematoxylin-eosin (H&E) sections and the densities of CD3 and CD8 T-lymphocytes by immunohistochemistry in a CRC cohort of 351 cases who underwent curative resection.
Poor infiltration of T lymphocytes has been regarded as a crucial mechanism of tumor immune escape. Here, we demonstrate a protective role of KRT17 in colorectal cancer, where KRT17 reversed the tumor immunosuppressive microenvironment by increasing T-lymphocyte infiltration. High-throughput RNA sequencing suggested that KRT17 was significantly upregulated in deficient mismatch repair (dMMR) tumors compared with proficient mismatch repair (pMMR) tumors.

Methods: Hypoxia-responsive circular RNAs (circRNAs) were identified by high throughput RNA sequencing between CRC cells cultured under normoxia or hypoxia.
Functional reprogramming of tumor-associated macrophages (TAMs) is crucial to their potent tumor-supportive capacity. However, the molecular mechanism behind the reprogramming process remains poorly understood. Here, we identify engulfment and cell motility protein 1 (ELMO1) as a crucial player for TAM reprogramming in colorectal cancer (CRC).

However, studies focusing on the combination of these two technologies are limited. This study aimed to evaluate perioperative results, long-term oncologic outcomes, and anorectal functions of patients with low rectal cancer undergoing taTME combined with ISR, by comparing with those of patients undergoing laparoscopic abdominoperineal resection (laAPR).

Here, we identify a previously unknown oncogenic role for inactive VHL in actively triggering histone lactylation to promote ccRCC progression. In patients with ccRCC, inactive VHL positively correlates with the presence of histone lactylation, and high levels of histone lactylation indicates poor patient prognosis.

However, the evidence is still lacking. This study compared the short and long outcomes of taTME with laTME in these "challenging" patients to explore the advantages of taTME among the patients.

Many previous studies reported positive relevant short-term results, histopathological results, and associated complications. Recently, concerns regarding the oncological safety of taTME have been raised due to reports showing high local recurrences (LR) rates.
View Article and Find Full Text PDFBackground: Ever since transanal total mesorectal excision was introduced by Sylla and Lacy in 2010, it has become more popular among colorectal surgeons. However, some surgeons hesitate to use it, because this novel approach differs greatly from laparoscopic total mesorectal excision and requires a long learning curve.
Objective: This study analyzed the learning curve of transanal total mesorectal excision procedure and compared the different phases of transanal total mesorectal excision with laparoscopic total mesorectal excision.
