Instructions for Authors
Cellular & Molecular Biology Letters publishes research articles, communications, review papers and mini reviews. Each volume consists of four issues.

Electronic submission is now mandatory for Cellular & Molecular Biology Letters. Please submit manuscripts directly using the Paper Processing System, which is available at or via our website
  1. In order to submit a manuscript via the Paper Processing System, first register as a new user, and then upload the manuscripts along with a covering letter. The paper should be prepared according to the journal style (see below) and uploaded as one .pdf or .docx file, with all of the figures and tables included in the main file in the main body of the text. The covering letter should contain all of the important details about the submission: your full name (as submitting author), the full title of your article, a full list of the authors, your email address and physical contact address, telephone and/or fax numbers, the number of attached files, the details of any previous or concurrent submissions, and 2–3 names of suggested reviewers.
  2. Together with submission, please send the completed Transfer of Copyright Agreement form, which is available for download from the Paper Processing System at and from our website The Managing Editor of the journal will send it on to the appropriate Editor.
  3. The Editor performs the initial review of the submitted manuscript. The Editor chosen for the initial review is always an expert in the relevant field. He then sends it on to 2–5 selected referees for a specialist review. The Editor decides whether the manuscript can be further considered for publication or not and asks for revisions based on the peer review.
  4. After making corrections, upload a revised version of the manuscript along with detailed replies to the reviewers’ comments to the Paper Processing System. The revised fragments of the manuscript should be in black font with a yellow highlight. Please note that many papers require minor revision or condensation. It is in the mutual interest of the authors and the journal that amended manuscripts are returned promptly. A revised paper will only retain its original date of receipt if the Editor receives it within 2 months of the date of return to the authors.
  5. The Editor refers the revised manuscript back to the referees. Based on these second reviews, the Editor decides whether the manuscript can be accepted for publication or not. If the corrections are satisfactory in general, but the manuscript still requires some revision, the Editor sends it to the authors for final, minor corrections. In the case of the second revision of an article, the authors need to return it within 14 days.
  6. The Managing Editor officially informs the author about the final decision on publication. The manuscript then undergoes language editing, after which it may again return to the authors for final acceptance of changes; technical editing; and final proofreading. Then, the manuscript is published, first online, and later in print form.
All the steps listed above occur within the Paper Processing System. Authors can log in to follow the editorial process in the system.

Starting with No. 1 Vol. 19 2014, we will indicate Invited Papers with a statement in the footnote of the first page.

The page charge of 20.00 EUR per page plus a postage fee for free reprints is to be paid the authors. However, payment of the charge is not a condition of publication, in particular for research that was not supported by an external grant source. Colour illustrations are published at the author’s expense cannot be the subject of a waiver. All figures submitted in colour will be published in colour, i.e., it is not possible to change from colour to black & white or vice versa after manuscript evaluation. The current prices are available from the Editors. The main author will receive 50 free offprints and also a free .pdf version of the paper.

  1. Submit the initial manuscript as a single .pdf file (preferably), with the MS Word format (.docx or .doc extension) as an optional back-up format. Insert all of the tables and figures into the text body. The file should be as small as possible. Please do not use non-specific file names, such as manuscript1, paper2 or article§, but identify the file by the last name of the first author and first word of the manuscript title.
  2. The text should be single spaced, and all of the pages should be numbered consecutively, including the references, tables, and figure legends. Conform to the general style of the journal and write in clear and grammatical English.
  3. Identify the type in the submission letter: regular manuscript, short communication, review, or mini review.
  4. Suggest at least 2 competent reviewers, providing their complete contact information, and indicate individuals who may be excluded from the review process.
  5. Identify the author for correspondence on the title page and provide his or her complete mailing address, telephone, fax numbers and an email address.

  12. Acknowledgments should be brief and should precede the references.
  13. References should be indicated in the text by Arabic numerals in square brackets (e.g., [23]) and numbered consecutively in order of appearance. The in-text references should not state the full names. The list of references should be typed at the end of the paper in the citation order in the style indicated below. Abbreviations of words in journal titles should be in bold and should finish with a period (e.g., J. Biol. Chem.). Full words in journal titles should not have a full stop (e.g., Cancer Res.). Journal volumes should be underlined. All of the authors’ names should be listed. Place ‘and’ between last two authors. Give the full title of the referenced article. Book titles should be given in full, and in bold. The first and last pages of references cited should be given in full (e.g., 341–347, not 341–7). Please note the positions of commas and spaces. DOI addresses could be helpful in addition. Website addresses should be included in the References section.

Headings. Main text headings should be typed in bold CAPITAL LETTERS (INTRODUCTION, MATERIALS AND METHODS, RESULTS, DISCUSSION, REFERENCES). Please do not number the sections.
Second-level headings should be typed in bold upper and sentence case (e.g., Assessment of protein concentrations).
Third-level headings should be in upper and sentence case letters, italics (e.g., Concentration of actin).

Tables. Insert tables using the standard insert function in Word. Place tables in the Word editor as close as possible to the place of reference in the text. Please use separate rows for each data set. Put Table #. (e.g., Table 1) and a short title at the top of the table in sentence case. References to tables should be given thus: (Table 1) or, e.g., „Table 1 shows the results of the analysis”.

Equations and formulas. All of the equations and formulas should be inserted as objects in the appropriate place in the text, and should be numbered. Please use Times New Roman fonts for equations. References to equations and formulas in the text should be given thus: (Equation 1) or (Formula 1) or, for example, „The value is calculated according to Formula 1”.

Figures and photographs. Use Arial font in sentence case for the in-figure and axis labels. The units should be in square brackets. Axis legends should be in sentence case. Please do not use bold or all caps for the in-figure labels.
High quality figures (at least 600 dpi, CMYK mode for colour) should be reduced to a suitable size (max. 12 cm in width) and pasted into the text as close as possible to the place of reference. Provide all figures as separate files with .tiff or .jpg extensions in addition to inserting them into the text. Figure with panels A, B, etc. should be provided as a single figure, not as multiple separate pieces. The panel indicators A, B, etc. should be placed in the upper left corner of the panel. Captions of figures with panels A, B, etc. should have a main (common) title, i.e., after Fig. 1., there should be a single-sentence general description of the figure before the specific description of the panel.
Use uniform line thickness and font sizes for all of the figures in the manuscript. There should be no variation in style from figure to figure and especially no difference in style between panels A and B of a single figure.
Type the figure captions underneath the inserted figures as part of the body text, not in text boxes or as part of the image. Label the figures Fig. #. (e.g., Fig. 1.) and label the parts A –, B –, etc.
References to figures in the text should be given thus: (Fig. 1) or, e.g., „Fig. 1 shows the results of the analysis”. References to parts of a figure should be given thus: (Fig. 1A) and (Fig. 1A and C). References to multiple figures should be given thus: (Figs 2 and 3).

When submitting a manuscript that reports on experiments involving humans or laboratory animals, both the cover letter and the Materials and Methods section of the manuscript must confirm that the experiments have adhered to the legal and ethical requirements of the country in which the study was conducted regarding such experiments.

  1. Please do not use .pdf, .dvi, or PostScript files at this stage, as these formats do not allow editing of the text. Most word-processing packages are acceptable, but we prefer that you use a recent version of Microsoft Word and save manuscripts with formatting intact (.docx, .doc extension).
  2. Submit each figure in the whole as a separate .tiff or .jpg file (in addition to those pasted in the text). The .tiff format is preferred. When creating your figures, use the Arial font. Sizes and line weights will reproduce clearly and accurately when the figures are sized to the appropriate width (6–12 cm). The minimum line weight is 1 point. Thinner lines will not reproduce well. Eliminate all excess white space from the borders of each figure. Please note that each graphics item should contain all its details, apart from those explained in the legend, in the same file, i.e., arrows, scale bars, asterisks, molecular weight standard values and indications of the panel, e.g., A, B, C. Number figures consecutively with Arabic numerals.
  3. A resolution of at least 600 dpi is required for quality reproduction. Colour photographs should be transmitted as CMYK colour. RGB images should be converted into CMYK, and all the necessary colour adjustments must be made prior to the transmission of the files. Authors must supply a colour-correct CMYK printout of all colour electronic art if the paper is accepted.
  4. Use your software’s spellcheck before final submission.
  5. The manuscript will be edited according to the style of the journal, and authors must read the proofs carefully. Proofs will be sent to the corresponding author as a .pdf file. To avoid delay in publication, only necessary changes should be made, and proofs should be returned promptly.
