1. Candidate pathogenicity factor/effector proteins of ‘Candidatus Phytoplasma solani’ modulate plant carbohydrate metabolism, accelerate the ascorbate–glutathione cycle, and induce autophagosomesMarina Dermastia, Špela Tomaž, Rebeka Strah, Tjaša Lukan, Anna Coll Rius, Barbara Dušak, Timotej Čepin, Aleš Kladnik, Maja Zagorščak, Kristina Gruden, Maruša Pompe Novak, 2023, original scientific article Abstract: The pathogenicity of intracellular plant pathogenic bacteria is associated with the action of pathogenicity factors/effectors, but their physiological roles for most phytoplasma species, including ‘Candidiatus Phytoplasma solani’ are unknown. Six putative pathogenicity factors/effectors from six different strains of ‘Ca. P. solani’ were selected by bioinformatic analysis. The way in which they manipulate the host cellular machinery was elucidated by analyzing Nicotiana benthamiana leaves after Agrobacterium-mediated transient transformation with the pathogenicity factor/effector constructs using confocal microscopy, pull-down, and co-immunoprecipitation, and enzyme assays. Candidate pathogenicity factors/effectors were shown to modulate plant carbohydrate metabolism and the ascorbate–glutathione cycle and to induce autophagosomes. PoStoSP06, PoStoSP13, and PoStoSP28 were localized in the nucleus and cytosol. The most active effector in the processes studied was PoStoSP06. PoStoSP18 was associated with an increase in phosphoglucomutase activity, whereas PoStoSP28, previously annotated as an antigenic membrane protein StAMP, specifically interacted with phosphoglucomutase. PoStoSP04 induced only the ascorbate–glutathione cycle along with other pathogenicity factors/effectors. Candidate pathogenicity factors/effectors were involved in reprogramming host carbohydrate metabolism in favor of phytoplasma own growth and infection. They were specifically associated with three distinct metabolic pathways leading to fructose-6-phosphate as an input substrate for glycolysis. The possible significance of autophagosome induction by PoStoSP28 is discussed.

3. Poročanje o neželenih učinkih med zdravljenjem s kemoterapijo : analiza raziskave OnkovedNina Privšek, Tina Zupančič, Ema Grašič, Marjetka Sraka, Klara Grad, Timotej Kovač, Matjaž Kukar, Cvetka Grašič-Kuhar, 2022, published scientific conference contribution Abstract: Zdravljenje s kemoterapijo je povezano s številnimi stranskimi učinki, ki so večinoma blagi in prehodne narave. Objektiviziramo jih glede na 5. izdajo skupnih terminoloških kriterijev za neželene učinke (angl. Common terminology criteria for adverse events; CTCAE). V zadnjih letih so v klinično uporabo vstopile tudi lestvice za bolnikovo poročanje neželenih učinkov (npr. PRO-CTCAE; angl. Patient reported outcomeCommon terminology criteria for adverse events). Raziskave, ki so do sedaj primerjale zdravnikova in bolnikova poročila o stranskih učinkih, so ugotovile, da zdravniki poročajo statistično značilno manj simptomov in nižje graduse kot bolniki. Nadalje je bilo ugotovljeno tudi, da tesnejši nadzor nad stranskimi učinki privede do hitrejše razrešitve težjih oblik le-teh. V pričujočem prispevku predstavljamo rezultate raziskave, ki smo jo izvedli na Onkološkem inštitutu Ljubljana za oceno stopnje pojavnosti ter razlik v beleženju stranskih učinkov s strani zdravnikov in bolnikov. V sklopu raziskave smo ocenjevali tudi kakovost življenja med zdravljenjem s kemoterapijo in doprinos uporabe mobilne aplikacije k učinkovitejšem obvladovanju stranskih učinkov v vsakdanji klinični praksi.
