Interuniversity Style Guide: for Writing Institutional Texts in English
[EN] The Interuniversity Style Guide for Writing Institutional Texts in English is designed for use by the administrative, teaching and research staff and language professionals who are responsible for writing institutional texts in English. Although one section focuses on how to write clearly, the word style in the title refers not to literary style but to those linguistic conventions concerning spelling, punctuation, typographical display and other editorial issues that are essential for consistent, clear and precise language and layout. Consistency in these areas leads to clarity and cohesion which, in turn, makes documents more straightforward for readers. As transmitters of knowledge, universities have to be rigorous in their use of language so that they can fulfil the scientific purpose of describing reality and making the complexity of this reality more readily understandable.[CA] El Manual dâestil interuniversitari per a la redacciĂł de textos institucionals en anglĂšs estĂ pensat per als docents, els investigadors, el personal dâadministraciĂł i serveis, i els professionals de la llengua que han de redactar documentaciĂł institucional en anglĂšs.

Genomic interplay between neoneurogenesis and neoangiogenesis in carcinogenesis : therapeutic interventions
Angiogenesis, the generation of new blood vessels, is one of the hallmarks of cancer. The
growing tumor requires nutrients and oxygen. Recent evidence has shown that tumors release
signals to attract new nerve fibers and stimulate the growth of new nerve fibers. Neurogenesis,
neural extension, and axonogenesis assist in the migration of cancer cells. Cancer cells can use both
blood vessels and nerve fibers as routes for cells to move along. In this way, neurogenesis and
angiogenesis both contribute to cancer metastasis. As a result, tumor-induced neurogenesis joins
angiogenesis and immunosuppression as aberrant processes that are exacerbated within the tumor
microenvironment. The relationship between these processes contributes to cancer development and
progression. The interplay between these systems is brought about by cytokines, neurotransmitters,
and neuromodulators, which activate signaling pathways that are common to angiogenesis and
the nervous tissue. These include the AKT signaling pathways, the MAPK pathway, and the Ras
signaling pathway. These processes also both require the remodeling of tissues. The interplay of
these processes in cancer provides the opportunity to develop novel therapies that can be used to
target these processes.The South African Medical Research Council (SAMRC) and the National Research Foundation (NRF).https://www.mdpi.com/journal/cancersam2024Medical OncologySurgerySDG-03:Good heatlh and well-bein

Alternative splicing events and their clinical significance in colorectal cancer : targeted therapeutic opportunities
Colorectal cancer (CRC) ranks as one of the top causes of cancer mortality worldwide
and its incidence is on the rise, particularly in low-middle-income countries (LMICs). There are
several factors that contribute to the development and progression of CRC. Alternative splicing (AS)
was found to be one of the molecular mechanisms underlying the development and progression
of CRC. With the advent of genome/transcriptome sequencing and large patient databases, the
broad role of aberrant AS in cancer development and progression has become clear. AS affects
cancer initiation, proliferation, invasion, and migration. These splicing changes activate oncogenes
or deactivate tumor suppressor genes by producing altered amounts of normally functional or new
proteins with different, even opposing, functions. Thus, identifying and characterizing CRC-specific
alternative splicing events and variants might help in designing new therapeutic splicing disrupter
drugs. CRC-specific splicing events can be used as diagnostic and prognostic biomarkers. In this
review, alternatively spliced events and their role in CRC development will be discussed. The paper
also reviews recent research on alternatively spliced events that might be exploited as prognostic,
diagnostic, and targeted therapeutic indicators. Of particular interest is the targeting of protein
arginine methyltransferase (PMRT) isoforms for the development of new treatments and diagnostic
tools. The potential challenges and limitations in translating these discoveries into clinical practice
will also be addressed.The South African Medical Research Council (SAMRC) and the National Research Foundation (NRF).https://www.mdpi.com/journal/cancersam2024Medical OncologySurgerySDG-03:Good heatlh and well-bein
MicroRNA and alternative mRNA splicing events in cancer drug response/resistance : potent therapeutic targets
Cancer is a multifaceted disease that involves several molecular mechanisms including
changes in gene expression. Two important processes altered in cancer that lead to changes in gene
expression include altered microRNA (miRNA) expression and aberrant splicing events. MiRNAs
are short non-coding RNAs that play a central role in regulating RNA silencing and gene expression.
Alternative splicing increases the diversity of the proteome by producing several different spliced
mRNAs from a single gene for translation. MiRNA expression and alternative splicing events are
rigorously regulated processes. Dysregulation of miRNA and splicing events promote carcinogenesis
and drug resistance in cancers including breast, cervical, prostate, colorectal, ovarian and leukemia.
Alternative splicing may change the target mRNA 30UTR binding site. This alteration can affect
the produced protein and may ultimately affect the drug affinity of target proteins, eventually
leading to drug resistance. Drug resistance can be caused by intrinsic and extrinsic factors. The
interplay between miRNA and alternative splicing is largely due to splicing resulting in altered
30UTR targeted binding of miRNAs. This can result in the altered targeting of these isoforms and
altered drug targets and drug resistance. Furthermore, the increasing prevalence of cancer drug
resistance poses a substantial challenge in the management of the disease. Henceforth, molecular
alterations have become highly attractive drug targets to reverse the aberrant effects of miRNAs and
splicing events that promote malignancy and drug resistance. While the miRNAâmRNA splicing
interplay in cancer drug resistance remains largely to be elucidated, this review focuses on miRNA
and alternative mRNA splicing (AS) events in breast, cervical, prostate, colorectal and ovarian
cancer, as well as leukemia, and the role these events play in drug resistance. MiRNA induced
cancer drug resistance; alternative mRNA splicing (AS) in cancer drug resistance; the interplay
between AS and miRNA in chemoresistance will be discussed. Despite this great potential, the interplay between aberrant splicing events and miRNA is understudied but holds great potential in
deciphering miRNA-mediated drug resistance.This research was funded by the South African Medical Research Council (SAMRC).The South African Medical Research Council (SAMRC)https://www.mdpi.com/journal/biomedicinesam2022Maxillo-Facial and Oral SurgeryMedical OncologySurger
Apoptosis in Cancer Cells Is Induced by Alternative Splicing of hnRNPA2/B1 Through Splicing of Bcl-x, a Mechanism that Can Be Stimulated by an Extract of the South African Medicinal Plant, Cotyledon orbiculata
Alternative splicing is deregulated in cancer and alternatively spliced products can be linked to cancer hallmarks. Targeting alternative splicing could offer novel effective cancer treatments. We investigated the effects of the crude extract of a South African medicinal plant, Cotyledon orbiculata, on cell survival of colon (HCT116) and esophageal (OE33 and KYSE70) cancer cell lines. Using RNASeq, we discovered that the extract interfered with mRNA regulatory pathways. The extract caused hnRNPA2B1 to splice from the hnRNPB1 to the hnRNPA2 isoform, resulting in a switch in the BCL2L1 gene from Bcl-xL to Bcl-xS causing activation of caspase-3-cleavage and apoptosis. Similar splicing effects were induced by the known anti-cancer splicing modulator pladienolide B. Knockdown of hnRNPB1 using siRNA resulted in decreased cell viability and increased caspase-3-cleavage, and over-expression of hnRNPB1 prevented the effect of C. orbiculata extract on apoptosis and cell survival. The effect of the hnRNPA2/B1 splicing switch by the C. orbiculata extract increased hnRNPA2B1 binding to Bcl-xl/s, BCL2, MDM2, cMYC, CD44, CDK6, and cJUN mRNA. These findings suggest that apoptosis in HCT116, OE33, and KYSE cancer cells is controlled by switched splicing of hnRNPA2B1 and BCL2L1, providing evidence that hnRNPB1 regulates apoptosis. Inhibiting this splicing could have therapeutic potential for colon and esophageal cancers. Targeting hnRNPA2B1 splicing in colon cancer regulates splicing of BCL2L1 to induce apoptosis. This approach could be a useful therapeutic strategy to induce apoptosis and restrain cancer cell proliferation and tumor progression. Here, we found that the extract of Cotyledon orbiculata, a South African medicinal plant, had an anti-proliferative effect in cancer cells, mediated by apoptosis induced by alternative splicing of hnRNPA2B1 and BCL2L1
Predator Mimicry: Metalmark Moths Mimic Their Jumping Spider Predators
Cases of mimicry provide many of the nature's most convincing examples of natural selection. Here we report evidence for a case of predator mimicry in which metalmark moths in the genus Brenthia mimic jumping spiders, one of their predators. In controlled trials, Brenthia had higher survival rates than other similarly sized moths in the presence of jumping spiders and jumping spiders responded to Brenthia with territorial displays, indicating that Brenthia were sometimes mistaken for jumping spiders, and not recognized as prey. Our experimental results and a review of wing patterns of other insects indicate that jumping spider mimicry is more widespread than heretofore appreciated, and that jumping spiders are probably an important selective pressure shaping the evolution of diurnal insects that perch on vegetation
Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
