Development of a new flippase-dependent mouse model for red fluorescence-based isolation of KRAS oncogene-expressing tumor cells.

Proto-oncogene KRAS, GTPase (KRAS) is one of the most intensively studied oncogenes in cancer research. Although several mouse models allow for regulated expression of mutant KRAS, selective isolation and analysis of transforming or tumor cells that produce the KRAS oncogene remains a challenge. In our study, we present a knock-in model of oncogenic variant KRAS that enables the "activation" of KRAS expression together with production of red fluorescent protein tdTomato.

Relationship Between Adenoma Detection Rate and Respective Withdrawal Time in Different Colon Segments: A Retrospective, Single-Center Study.

Background And Aims: The 6-min withdrawal time for colonoscopy is widely considered the standard of care. However, there may not be appropriate if the 6-min is equally divided into various colon segments. Since the adenoma detection in each colon segment is not the same, there may be differences with the withdrawal time in different colon segments.

A Rare Case with Recurrent Abdominal Pain as the First Symptom: AL Amyloidosis with Colon Involvement Combined with Pulmonary Adenocarcinoma.

Background: Amyloidosis combined with lung cancer is a rare occurrence. To date, there are no reported cases of amyloid light-chain(AL) amyloidosis solely affecting the colon combined with pulmonary adenocarcinoma.

Case Summary: Here, we describe a case of a 66-year-old woman who presented with recurrent abdominal pain and was eventually diagnosed with AL amyloidosis with colon involvement and pulmonary adenocarcinoma.
