Abstract
Circadian Locomotor Output Cycles Kaput (CLOCK) is one of the circadian clock genes and is considered to be a fundamental regulatory gene in the circadian rhythm, responsible for mediating several biological processes. Therefore, abnormal expression of CLOCK affects its role in the circadian clock and its more general function as a direct regulator of gene expression. This dysfunction can lead to severe pathological effects, including cancer. To better understand the role of CLOCK in cancer, we compiled this review to describe the biological function of CLOCK, and especially highlighted its function in cancer development, progression, tumor microenvironment, cancer cell metabolism, and drug resistance.

Abstract
Circadian rhythm is a roughly 24-h wake and sleep cycle that almost all of the organisms on the earth follow when they execute their biological functions and physiological activities. The circadian clock is mainly regulated by the transcription-translation feedback loop (TTFL), consisting of the core clock proteins, including BMAL1, CLOCK, PERs, CRYs, and a series of accessory factors. The circadian clock and the downstream gene expression are not only controlled at the transcriptional and translational levels but also precisely regulated at the post-translational modification level. Recently, it has been discovered that CLOCK exhibits lysine acetyltransferase activities and could acetylate protein substrates. Core clock proteins are also acetylated, thereby altering their biological functions in the regulation of the expression of downstream genes. Studies have revealed that many protein acetylation events exhibit oscillation behavior. However, the biological function of acetylation on circadian rhythm has only begun to explore. This review will briefly introduce the acetylation and deacetylation of the core clock proteins and summarize the proteins whose acetylation is regulated by CLOCK and circadian rhythm. Then, we will also discuss the crosstalk between lysine acetylation and the circadian clock or other post-translational modifications. Finally, we will briefly describe the possible future perspectives in the field.

P-element-Induced Wimpy-Testis-Like Protein 1 Regulates the Activation of Pancreatic Stellate Cells Through the PI3K/AKT/mTOR Signaling Pathway. Dig Dis Sci 2022; 68:1339-1350.

Abstract
AIM Pancreatic fibrosis is the main pathological characteristic of chronic pancreatitis (CP) and pancreatic cancer. Pancreatic stellate cells (PSCs) play a critical role in pancreatic fibrosis. Any targets that may have an impact on the activation of PSCs could become potential treatment candidates for CP and pancreatic cancer. Our goal was to investigate the effect of P-element-induced wimpy-testis (PIWI) protein 1 (PIWIL1) on PSC activation. METHODS Lentivirus-based RNA interference (RNAi) and overexpression vector construction were used to knock down and over-express the PIWIL1 protein. Immunocytofluorescent staining, western blotting, wound healing assay, transwell assay, and phalloidin staining were used to investigate the effects of PIWIL1 on the secretion of extracellular matrix components (EMC), actin cytoskeleton, and on the invasion and migration abilities of primary PSCs isolated from C57BL/6 mice. Moreover, pancreatic fibrosis was induced by L-arginine in C57BL/6 mice. The expression of PIWIL1 and collagen deposition in vivo were tested by western blotting and Sirius red staining. RESULTS Expression levels of collagen I, collagen III, and α-smooth muscle actin were significantly decreased in the LV-PIWIL1 group. Compared with the si-PIWIL1 group, significant differences were observed in the expression of desmin, p-PI3K, p-AKT, and p-mTOR in the LV-PIWIL1 group. Furthermore, PIWIL1 suppressed the PSCs' invasion and migration abilities. In a rescue experiment, the PI3K/AKT/mTOR signaling pathway was found to be the underlying mechanism in PSCs activation mediated by PIWIL1. CONCLUSIONS Our findings suggest that PIWIL1 inhibits the activation of PSCs via the PI3K/AKT/mTOR signaling pathway. PIWIL1 is a potential therapeutic target for pancreatic fibrosis.

Circadian Alterations Increase with Progression in a Patient-Derived Cell Culture Model of Breast Cancer. Clocks Sleep 2021; 3:598-608. [PMID: 34842634 PMCID: PMC8628750 DOI: 10.3390/clockssleep3040042] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 10/10/2021] [Accepted: 10/28/2021] [Indexed: 01/20/2023] Open
Abstract
Circadian rhythm disruption can elicit the development of various diseases, including breast cancer. While studies have used cell lines to study correlations between altered circadian rhythms and cancer, these models have different genetic backgrounds and do not mirror the changes that occur with disease development. Isogenic cell models can recapitulate changes across cancer progression. Hence, in this study, a patient-derived breast cancer model, the 21T series, was used to evaluate changes to circadian oscillations of core clock protein transcription as cells progress from normal to malignant states. Three cell lines were used: H16N2 (normal breast epithelium), 21PT (atypical ductal hyperplasia), and 21MT-1 (invasive metastatic carcinoma). The cancerous cells are both HER2+. We assessed the transcriptional profiles of two core clock proteins, BMAL1 and PER2, which represent a positive and negative component of the molecular oscillator. In the normal H16N2 cells, both genes possessed rhythmic mRNA oscillations with close to standard periods and phases. However, in the cancerous cells, consistent changes were observed: both genes had periods that deviated farther from normal and did not have an anti-phase relationship. In the future, mechanistic studies should be undertaken to determine the oncogenic changes responsible for the circadian alterations found.

Abstract
Circadian rhythms are maintained by series of circadian clock proteins, and post-translation modifications of clock proteins significantly contribute to regulating circadian clock. However, the underlying upstream mechanism of circadian genes that are responsible for circadian rhythms in cancer cells remains unknown. PIWIL1 participates in many physiological processes and current discoveries have shown that PIWIL1 is involved in tumorigenesis in various cancers. Here we report that PIWIL1 can suppress circadian rhythms in cancer cells. Mechanistically, by promoting SRC interacting with PI3K, PIWIL1 can activate PI3K-AKT signalling pathway to phosphorylate and inactivate GSK3β, repressing GSK3β-induced phosphorylation and ubiquitination of CLOCK and BMAL1. Simultaneously, together with CLOCK/BMAL1 complex, PIWIL1 can bind with E-BOX region to suppress transcriptional activities of clock-controlled genes promoters. Collectively, our findings first demonstrate that PIWIL1 negatively regulates circadian rhythms via two pathways, providing molecular connection between dysfunction of circadian rhythms and tumorigenesis.
